Affirmed by published opinion. Judge THACKER wrote the opinion, in which Judge MOTZ and Judge KING joined. THACKER, Circuit Judge: Over the course of five weeks of trial, federal prosecutors sought to prove that former Governor of Virginia Robert F. McDonnell (“Appellant”) and his wife, Maureen McDonnell, accepted money and lavish gifts in exchange for efforts to assist a Virginia company in securing state university testing of a dietary supplement the company had developed. The jury found Appellant guilty of eleven counts of corruption and not guilty of two counts of making .a false statement. Appellant appeals his convictions, alleging a multitude of errors. Chiefly, Appellant challenges the jury instructions— claiming the district court misstated the law — and the sufficiency of the evidence presented against him. He also argues that his trial should have been severed from his wife’s trial; that the district court’s voir dire questioning violated his Sixth Amendment rights; and that the district court made several erroneous evi-dentiary rulings. Upon consideration of each of Appellant’s contentions, we conclude that the jury’s verdict must stand and that the district court’s judgment should be affirmed. I. A. On November 3, 2009, Appellant was elected the seventy-first Governor of Virginia. From the outset, he made economic development and the promotion of Virginia businesses priorities of his administration. The economic downturn preceding the election had taken a personal toll on Appellant. Mobo Real Estate Partners LLC (“Mobo”), a business operated by Appellant and his sister, was losing money on a pair of beachfront rental properties in Virginia Beach. When Appellant became Governor, he and his sister were losing more than $40,000 each year. By 2011, they owed more than $11,000 per month in loan payments. Each year their loan balance increased, and by 2012, the outstanding balance was nearing $2.5 million. Appellant was also piling up credit card debt. In January 2010, the month of his inauguration, Appellant and his wife had a combined credit card balance exceeding $74,000. Eight months later, in September 2010, the combined balance exceeded $90,000. B. While Appellant was campaigning on promises of economic development in Virginia, Virginia-based Star Scientific Inc. (“Star”) and its founder and chief executive officer Jonnie Williams were close to launching a new product: Anatabloc. For years, Star had been evaluating the curative potential of anatabine, an alkaloid found in the tobacco plant, focusing on whether it could be used to treat chronic inflammation. Anatabloc was one of the anatabine-based dietary supplements Star developed as a result of these years of evaluation. Star wanted the Food and Drug Administration to classify Anatabloc as a pharmaceutical. Otherwise, it would have to market Anatabloc as a nutraceutical, which generally has less profit potential than a pharmaceutical. Classification as a pharmaceutical would require expensive testing, clinical trials, and studies. But Star did not have the financial wherewithal to conduct the necessary testing, trials, and studies on its own. It needed outside research and funding. C. Appellant and Williams first met in December 2009 — shortly after Appellant’s election to the governorship but before his inauguration. Appellant had used Williams’s plane during his campaign, and he wanted to thank Williams over dinner in New York. During dinner, Williams ordered a $5,000 bottle of cognac and the conversation turned to the gown Appellant’s wife would wear to Appellant’s inauguration. Williams mentioned that he knew Oscar de la Renta and offered to purchase Mrs. McDonnell an expensive custom dress. In October 2010, Appellant and Williams crossed paths again. This time, the two were on the same plane — Williams’s plane — making their way from California to Virginia. During the six-hour flight, Williams extolled the virtues of Anatabloc and explained that he needed Appellant’s help to move forward with the product: [W]hat I did was I explained to him how I discovered it. I gave him a basic education on the — on smoking, the diseases that don’t happen with smokers and just tried to make sure he understood, you know, what I had discovered in this tobacco plant and that I was going to — what I needed from him was that I needed testing and I wanted to have this done in Virginia. J.A. 2211. By the end of the flight, the two agreed that “independent testing in Virginia was a good idea.” J.A. 2211. Appellant agreed to introduce Williams to Dr. William A. Hazel Jr., the Commonwealth’s secretary of health and human resources. In April 2011, Mrs. McDonnell invited Williams to join the first couple at a political rally in New York. “I’ll have you seated with the Governor and we can go shopping now,” Mrs. McDonnell said, according to Williams. J.A. 2222 (internal quotation marks omitted). So Williams took Mrs. McDonnell on a shopping spree; they lunched and shopped at Bergdorf Goodman and visited Oscar de la Renta and Louis Vuitton stores on Fifth Avenue. Williams bought Mrs. McDonnell dresses and a white leather coat from Oscar de la Renta; shoes, a purse, and a raincoat from Louis Vuitton; and a dress from Bergdorf Goodman. Williams spent approximately $20,000 on Mrs. McDonnell during this shopping spree. That evening, Williams sat with Appellant and Mrs. McDonnell during a political rally. A few weeks later, on April 29, Williams joined Appellant and Mrs. McDonnell for a private dinner at the Governor’s Mansion. The discussion at dinner centered on Ana-tabloc and the need for independent testing and studies. Appellant, who had campaigned on promoting business in Virginia, was “intrigued that [Star] was a Virginia company with an idea,” and he wanted to have Anatabloc studies conducted within the Commonwealth’s borders. J.A. 6561. Two days after this private dinner — on May 1, 2011 — Mrs. McDonnell received an email via Williams. The email included a link to an article entitled “Star Scientific Has Home Run Potential,” which discussed Star’s research and stock. Mrs. McDonnell forwarded this email to Appellant at 12:17 p.m. Less than an hour later, Appellant texted his sister, asking for information about loans and bank options for their Mobo properties. Later that evening, Appellant emailed his daughter Cai-lin, asking her to send him information about the payments he still owed for her wedding. The next day, May 2, Mrs. McDonnell and Williams met at the Governor’s Mansion to discuss Anatabloc. However, Mrs. McDonnell began explaining her family’s financial woes — thoughts about filing for bankruptcy, high-interest loans, the decline in the real estate market, and credit card debt. Then, according to Williams, Mrs. McDonnell said, “I have a background in nutritional supplements and I can be helpful to you with this project, with your company. The Governor says it’s okay for me to help you and — but I need you to help me. I need you to help me with this financial situation.” J.A. 2231 (internal quotation marks omitted). Mrs. McDonnell asked to borrow $50,000. Williams agreed to loan the money to the McDonnells. Mrs. McDonnell also mentioned that she and her husband owed $15,000 for their daughter’s wedding reception. Again, Williams agreed to provide the money. Before cutting the checks, Williams called Appellant to “make sure [he] knew about it.” J.A. 2233. “I called him and said that, you know, T met with Maureen. I understand the financial problems and I’m willing to help. I just wanted to make sure that you knew about this,’ ” Williams recounted at trial. Id. Appellant’s response was “Thank you.” Id. Three days later, on May 5 at 11 a.m., Appellant met with Secretary Hazel and Chief of Staff Martin Kent to discuss the strategic plan for the state’s health and human resources office. Shortly after the meeting, Appellant directed his assistant to forward to Hazel the article about Star that Mrs. McDonnell had earlier brought to Appellant’s attention. Williams returned to the Governor’s Mansion on May 23, 2011, to deliver two checks for the amounts discussed on May 2: a $50,000 check made out to Mrs. McDonnell and a $15,000 check that was not made out to anyone but was going to the wedding caterers. After Williams delivered these checks to Mrs. McDonnell, Appellant expressed his gratitude in a May-28 email to Williams: Johnnie. Thanks so much for alll your help -with my family. Your very generous gift to Cailin was most appreciated as well as the golf round tomorrow for the boys. Maureen is excited about the trip to fla to learn more about the products .... Have a restful weekend with your family. Thanks. G.S.A. 20. The next day, as mentioned in the email, Appellant, his two sons, and his soon-to-be son-in-law spent the day at Kin-loch Golf Club in Manakin-Sabot, Virginia. During this outing, they spent more than seven hours playing golf,.eating, and shopping. Williams, who was not present, covered the $2,380.24 bill. Also as mentioned in the email, Mrs. McDonnell traveled to Florida at the start of June to attend a Star-sponsored event at the Roskamp Institute. While there, she addressed the audience, expressing her support for Star and its research. She also invited the audience to the launch for Anatabloc, which would be held at the Governor’s Mansion. The same day— June 1, 2011 — she purchased 6,000 shares of Star stock at $5.1799 per share, for a total of $31,079.40. Weeks later, Williams sent Appellant a letter about conducting Anatabloc studies in Virginia. Williams wrote, “I am suggesting that you use the attached protocol to initiate the Virginia study’ of Anatabloc at the Medical College of Virginia and the University of Virginia School of Medicine, with an emphasis on endocrinology, cardiology, osteoarthritis and gastroenterolo-gy.” G.S.A. 29. Appellant forwarded the letter and its attachments to Secretary Hazel for review. Appellant’s political action committee— Opportunity Virginia (the “PAC”) — hosted and funded a retreat at the Omni Homestead Resort in Hot Springs, Virginia. The retreat began on June 23, 2011, and was attended by the top donors to Opportunity Virginia. Williams, “a $100,000 in-kind contributor to the campaign and the PAC,” was invited, and he flew Appellant’s children to the resort for the retreat. J.A. 6117. Appellant and Williams played golf together during the retreat. A few days later, Williams sent golf bags with brand new clubs and golf shoes to Appellant and one of his sons. From July 28 to July 31, Appellant and his family vacationed at Williams’s multimillion-dollar home at Smith Mountain Lake in Virginia. Williams allowed the McDonnells to stay there free of charge. He also paid $2,268 for the McDonnells to rent a boat. And Williams provided transportation for the family: Appellant’s children used Williams’s Range Rover for the trip to the home, and he paid more than $600 to have his Ferrari delivered to the home for Appellant to use. Appellant drove the Ferrari back to Richmond at the end of the vacation on July 31. During the three-hour drive, Mrs. McDonnell snapped several pictures of Appellant driving with the Ferrari’s top down. Mrs. McDonnell emailed one of the photographs to Williams at 7:47 p.m. At 11:29 p.m., after returning from the Smith Mountain Lake vacation, Appellant directed Secretary Hazel to have his deputy attend a meeting about Anatabloc with Mrs. McDonnell at the Governor’s Mansion the next day. Hazel sent a staffer, Molly Huffstetler, to the August 1 meeting, which Williams also attended. During the meeting, Williams discussed clinical trials at the University of Virginia (“UVA”) and Virginia Commonwealth University (“VCU”), home of the Medical College of Virginia (“MCV”). Then Williams and Mrs. McDonnell met with Dr. John Clore from VCU, who Williams said was “important, and he could cause studies to happen at VCU’s medical school.” J.A. 2273. Williams — with Mrs. McDonnell at his side — told Dr. Clore that clinical testing of Anatabloc in Virginia was important to Appellant. After the meeting ended, Mrs. McDonnell noticed the Rolex watch adorning Williams’s wrist. She mentioned that she wanted to get a Rolex for Appellant. When Williams asked if she wanted him to purchase one for Appellant, she responded affirmatively. The next day — -August 2, 2011 — Mrs. McDonnell purchased another 522 shares of Star stock at $3.82 per share, for a total of $1,994.04. Appellant and one of his sons returned to Kinloch Golf Club on August 13, 2011. The bill for this golf outing, which Williams again paid, was $1,309.17. The next day, Williams purchased a Rolex from Malibu Jewelers in Malibu, California. The Rolex cost between $6,000 and $7,000 and featured a custom engraving: “Robert F. McDonnell, 71st Governor of Virginia.” J.A. 2275 (internal quotation marks omitted). Mrs. McDonnell later took several pictures of Appellant showing off his new Rolex — pictures that were later sent to Williams via text message. Over the next few weeks, Governor’s Mansion staff planned and coordinated a luncheon to launch Anatabloc — an event paid for by Appellant’s PAC. Invitations bore the Governor’s seal and read, “Governor and Mrs. Robert F. McDonnell Request the Pleasure of your Company at a Luncheon.” G.S.A. 104. Invitees included Dr. Clore and Dr. John Lazo from UVA. At the August 30 luncheon, each place setting featured samples of Anatabloc, and Williams handed out checks for grant applications — each for $25,000 — to doctors from various medical institutions. Appellant also attended the luncheon. According to Lazo, Appellant asked attendees various questions about their thoughts about Anatabloc: So I think one question he asked us was, did we think that there was some scientific validity to the conversation and some of the pre-clinical studies that were discussed, or at least alluded to. He also, I think, asked us whether or not there was any reason to explore this further; would it help to have additional information. And also, he asked us about could this be something good for the Commonwealth, particularly as it relates to [the] economy or job creation. J.A. 3344. According to Williams, Appellant was “[a]sking questions like ... ‘What are the end points here? What are you looking for to show efficacy with the studies? How are you going to proceed with that?’ ” Id. at 2283. Appellant also thanked the attendees for their presence and “talked about his interest in a Virginia company doing this, and his interest in the product.” Id. at 3927. Overall, “[Appellant] was generally supportive.... [T]hat was the purpose.” Id. at 2284. Despite the fanfare of the luncheon, Star’s President, Paul L. Perito, began to worry that Star had lost the support of UVA and VCU. In the fall of 2011, Perito was working with those universities to file grant applications. During a particular call with UVA officials, Perito felt the officials were unprepared. According to Peri-to, when Williams learned about this information, “[h]e was furious and said, ‘I can’t understand it. [Appellant] and his wife are so supportive of this and suddenly the administration has no interest.’ ” J.A. 3934. D. Prior to the beginning of 2012, Mrs.McDonnell sold all of her 6,522 shares of Star stock for $15,279.45, resulting in a loss of more than $17,000. This allowed Appellant to omit disclosure of the stock purchases on a required financial disclosure form known as a Statement of Economic Interest. Then on January 20, 2012 — four days after the Statement of Economic Interest had been filed — Mrs. McDonnell purchased 6,672 shares of Star stock at $2.29 per share, for a total of $15,276.88. In the meantime, on January 7, 2012, Appellant made another golf visit to Kin-loch Golf Club, running up a $1,368.91 bill that Williams again paid. Appellant omitted this golf outing and the 2011 golf trips from his Statements of Economic Interest. See J.A. 723 (noting Appellant’s “deliberate omission of his golf-related gifts paid by Jonnie Williams”). Appellant also omitted from his Statement of Economic Interest the $15,000 check for the caterers at his daughter’s wedding. Also in January 2012, Williams discussed the Mobo properties with Mrs. McDonnell, who wanted additional loans. As a result, Williams agreed to loan more money. At the same time, he mentioned to Mrs. McDonnell that the studies with UVA were proceeding slowly. Mrs. McDonnell was “furious when [Williams] told her that [they were] bogged down in the administration.” J.A. 2308. Later, Mrs. McDonnell called Williams to advise him that she had relayed this information to Appellant, who “want[ed] the contact information of the people that [Star] [was] dealing with at [UVA].” Id. at 2309 (internal quotation marks omitted). Appellant followed up on these discussions by calling Williams on February 3, 2012, to talk about a $50,000 loan. Initially, Appellant wanted a cash loan, but Williams mentioned that he could loan stock to Appellant. Williams proposed “that he could loan that stock either to [Appellant’s] wife or he could loan it to [Mobo].” J.A. 6224. This conversation continued to February 29, when Williams visited the Governor’s Mansion. During this meeting, Appellant and Williams discussed the potential terms of a stock transfer. However, Appellant and Williams did not move forward with this idea because Williams discovered he would have to report a stock transfer to the Securities and Exchange Commission. At trial, Williams testified that he did not want to transfer Star stock because he “didn’t want anyone to know that I was helping the Governor financially with his problems while he was helping our company.” Id. at 2333-34. When asked what he expected in return from Appellant, Williams testified, “I expected what had already happened, that he would continue to help me move this product forward in Virginia” by “assisting with the universities, with the testing, or help with government employees, or publicly supporting the product.” Id. at 2355. In the end, Williams agreed to make a $50,000 loan, writing a check in this amount to the order of Mobo on March 6. Also on February 3, one of Williams’s employees responded to Mrs. McDonnell’s request for a list of doctors Williams wished to invite to an upcoming healthcare industry leaders reception at the Governor’s Mansion. The employee emailed the list of doctors to Mrs. McDonnell. Four ' days later — on February 7 — Mrs. McDonnell sent a revised list of invitees for this event, a list that now included the doctors identified by .Williams. The next day, Sarah Scarbrough, director of the Governor’s Mansion, sent an email to Secretary Hazel’s assistant, Elaina Schramm. Scarb-rough informed Schramm that “[t]he First Lady and Governor were going over the list last night for the healthcare industry event. The Governor wants to make sure [head officers at UVA and VCU, along with those of other institutions,] are included in the list.” G.S.A. 146. Mrs. McDonnell received an email, as previously requested by Appellant, containing the names of the UVA officials with whom Star had been working. She forwarded this list to Appellant and his chief counsel, Jacob Jasen Eige, on February 9. The next day, while riding with Appellant, Mrs. McDonnell followed up with Eige: Pis call Jonnie today [and] get him to fill u in on where this is at. Gov wants to know why nothing has developed w studies after Jonnie gave $200,000. I’m just trying to talk w Jonnie. Gov wants to get this going w VCU MCV. Pis let us know what u find out after we return .... G.S.A. 154. Less than a week later — on February 16, 2012 — Appellant emailed Williams to check on the status of certificates and documents relating to loans Williams was providing for Mobo. Six minutes after Appellant sent this email, he emailed Eige: “Pis see me about anatabloc issues at VCU and UVA. Thx.” G.S.A. 157. The healthcare industry leaders reception was held on February 29 — the same day as Appellant’s private meeting about securing a loan from Williams. Following the reception, Appellant, Mrs. McDonnell, Williams, and two doctors went out for a $1,400 dinner on Williams’s dime. During dinner the diners discussed Anatabloc. Mrs. McDonnell talked about her use of Anatabloc, and Appellant asked one of the doctors — a Star consultant — “How big of a discovery' is this?” J.A. 2728 (internal quotation marks omitted). At one point during the dinner Mrs. McDonnell invited the two doctors to stay at the Governor’s Mansion for the evening — an offer the doctors accepted. On March 21, 2012, Appellant met with Virginia Secretary of Administration Lisa Hicks-Thomas, who oversaw state employee health plans and helped determine which drugs would be covered by the state health plan. At one point during the meeting, Appellant reached into his pocket, retrieving a bottle of Anatabloc. He told Hicks-Thomas that Anatabloc was “working well for him, and that he thought it would be good for ... state employees.” J.A. 4227. He then asked Hicks-Thomas to meet with representatives from Star. Almost two months later — on May 18, 2012 — Appellant sent Williams a text message concerning yet another loan: “Johnnie. Per voicemail would like to see if you could extend another 20k loan for this year. Call if possible and I’ll ask mike to send instructions. Thx bob.” G.S.A. 166. Twelve minutes later, Williams responded, “Done, tell me who to make it out to and address. Will FedEx. Jonnie.” Id. at 168. Later the same month — from May 18 to May 26 — Appellant and his family vacationed at Kiawah Island in South Carolina. According to Appellant, the $23,000 vacation was a gift from William H. Goodwin Jr., whom Appellant characterized as a personal friend. Appellant did not report this gift on his 2012 Statement of Economic Interest. He said he did not need to report it because it fell under the “personal friend” exception to the reporting requirements. Between April and July 2012, Appellant emailed and texted Williams about Star stock on four occasions, each coinciding with a rise in the stock price. In response to a text sent on July 3, Williams said, “Johns Hopkins human clinical trials report on Aug. 8. If you need cash let me know. Let’s go golfing and sailing Chat-ham Bars inn Chatham mass labor day weekend if you can. Business about to break out strong. Jonnie.” G.S.A. 170. Appellant and his wife took Williams up on his Labor Day weekend vacation offer. Williams spent more than $7,300 on this vacation for the McDonnells. Williams paid the McDonnells’ share of a $5,823.79 bill for a private clambake. Also joining in on the weekend excursion was one of the doctors who attended the February healthcare leaders reception, whom Williams invited in an áttempt “to try to help get the Governor more involved.” J.A. 2371. Appellant said he learned in December 2012 that Mrs. McDonnell had repurchased Star stock in January 2012 — despite having sold her entire holding of Star stock the previous year. Appellant testified that he “was pretty upset with her.” J.A. 6270. This revelation led to a tense conversation about reporting requirements: [I]t was her money that she had used for this. But I told her, you know, “Listen. If you have this stock, you know, this is” — “again, triggers a reporting requirement for me. I can do it, but I need” — “I just don’t” — “I really don’t appreciate you doing things that really” — “that affect me without” — “without me knowing about it.” Id. at 6271. That Christmas, Mrs. McDonnell transferred her Star stock to her children as a gift. This again allowed Appellant to file a Statement of Economic Interest that did not report ownership of the stock. That same month — December 2012 — Williams gave Appellant’s daughter Jeanine a $10,000 wedding gift. E. Eventually, all of these events came to light. And on January 21, 2014, a grand jury indicted Appellant and Mrs. McDonnell in a fourteen-count indictment. Appellant and Mrs. McDonnell were charged with one count of conspiracy to commit honest-services wire fraud, in violation of 18 U.S.C. § 1349; three counts of honest-services wire, fraud, in violation of 18 U.S.C. § 1343; one count of conspiracy to obtain property under color of official right, in violation of 18 U.S.C. § 1951; six counts of obtaining property under color of official right, in violation of 18 U.S.C. § 1951; two counts of making a false statement, in violation of 18 U.S.C. § 1014; and one count of obstruction of official proceedings, in violation of 18 U.S.C. § 1512(c)(2). Ultimately, the jury verdict of September 4, 2014, found Appellant not guilty of the false statements counts but guilty of all eleven counts of corruption. At sentencing the Government requested a sentence of 78 months — or six and a half years — of imprisonment, which was at the low end of the applicable Sentencing Guidelines range. However, the district court departed downward and sentenced Appellant to two years of imprisonment, followed by two years of supervised re-, lease. Appellant now challenges his convictions, asserting a litany of errors. II. A. Motion for Severance To begin, Appellant argues that the district court erred when it denied both his motion for severance and his request for ex parte consideration of this motion. We review these rulings for an abuse of discretion. See United States v. Lighty, 616 F.3d 321, 348 (4th Cir.2010) (severance); RZS Holdings AVV v. PDVSA Petroleo S.A., 506 F.3d 350, 356 (4th Cir.2007) (ex parte proceeding). 1. Appellant contends that he was entitled to a trial separate from the trial of Mrs. McDonnell. He argues that a joint trial precluded him . from calling Mrs. McDonnell as a witness and thus introducing exculpatory testimony. The district court denied Appellant’s motion for severance. Appellant claims this decision was an abuse of the court’s discretion. In general, “defendants indicted together should be tried together.” Lighty, 616 F.3d at 348. This is especially true when, as in this case, the defendants are charged with conspiracy. See United States v. Parodi 703 F.2d 768, 779 (4th Cir.1983). So a defendant seeking severance based on the need for a co-defendant’s testimony must make an initial showing of “(1) a bona fide need for the testimony of his co-defendant, (2) the likelihood that the co-defendant would testify at a second trial and waive his Fifth Amendment privilege, (3) the substance of his co-defendant’s testimony, and (4) the exculpatory nature and effect of such testimony.” Id. After the initial showing is made, a district court should (1) examine the significance of the testimony in relation to the defendant’s theory of defense; (2) assess the extent of prejudice caused by the absence of the testimony; .(3) pay close attention to judicial administration and economy; (4) give weight to the timeliness of the motion!;] and (5) consider the likelihood that the co-defendant’s testimony could be impeached. Id. Appellant failed to satisfy even the initial showing requirements of United States v. Parodi. The district court denied Appellant’s motion for severance because Appellant offered only vague and conclusory statements regarding the substance of Mrs. McDonnell’s testimony. As we expressed in Parodi vague and conclu-sory statements regarding potential testimony are not enough to establish the substance of a co-defendant’s testimony. See 703 F.2d at 780. Appellant’s motion to sever paints a picture of Mrs. McDonnell’s potential testimony in broad strokes without filling in any details: First, her testimony would disprove the Government’s primary claim that the McDonnells acted in concert through a criminal conspiracy to corruptly accept gifts and loans in exchange for Mr. McDonnell using his office to benefit Williams and his company. Second, her testimony would refute the Government’s allegation that Mr. McDonnell agreed or promised to use his office to improperly “promote” Star’s products or to “obtain research studies for Star Scientific’s products.” Third, Mrs. McDonnell would refute the Government’s allegation that she solicited certain gifts and loans identified in the Indictment. Finally, Mrs. McDonnell would refute the Government’s allegation that the McDonnells “took steps ... to conceal” their supposed scheme. J.A. 296 (alternation in original) (citations omitted). Presented with only these unadorned statements regarding the substance of Mrs. McDonnell’s potential tés-timony, the district court appropriately exercised its discretion when it denied the motion to sever. 2. Appellant claimed he could provide a more detañed account of the substance of Mrs. McDonnell’s potential testimony — an account he offered to share with the district court on the condition that the district court review the evidence ex parte. The district court denied this invitation, finding an ex parte proceeding would be inappropriate. Ex parte proceedings and communications are disfavored because they are “fundamentally at variance with our conceptions of due process.” Doe v. Hampton, 566 F.2d 265, 276 (D.C.Cir.1977), quoted in Thompson v. Greene, 427 F.3d 263, 269 n. 7 (4th Cir.2005). However, such proceedings and communications may be permissible in limited eircum-stances. “[0]ur analysis should focus, first, on the parties’ opportunity to participate in the court’s decision and, second, on whether the ex parte proceedings were unfairly prejudicial.” RZS Holdings AW, 506 F.3d at 357. Ex parte proceedings were not justified in this case. Appellant sought to withhold from the Government all of the information necessary to establish the necessity of severance. This proposal would have barred the Government from challenging whether Appellant actually satisfied the initial showing required by Parodi. If the district court proceeded as Appellant requested, it would have been the only entity in a position to challenge Appellant’s contentions. The district court was reluctant to assume the role of an advocate when evaluating “a motion to sever[, which] requires a fact-intensive, multi-factored analysis for which there is a heightened need for well-informed advocacy.” J.A. 351. It properly exercised its discretion by denying Appellant’s request. Appellant also maintains that the district court erred by failing to defer its ruling on the motion to sever until 14 days prior to trial. The district court was not obligated to consider this request because Appellant waited until his reply to argue this issue. Cf. U.S. S.E.C. v. Pirate Investor LLC, 580 F.3d 233, 255 n. 23 (4th Cir.2009) (“Ordinarily we do not consider arguments raised for the first time in a reply brief.Mike’s Train House, Inc. v. Broadway Ltd. Imports, LLC, 708 F.Supp.2d 527, 535 (D.Md.2010) (applying this principle to reply memoranda). We are satisfied, therefore, that the district court did not abuse its discretion by denying this request outright. Appellant simply failed to provide adequate justification for his claim that a severance was'warranted. He was not entitled to an ex parte examination of his evidence; he was not entitled to deferral of the district court’s ruling. Accordingly, we affirm the denial of Appellant’s motion to sever. • B. Voir Dire Appellant next argues that the district court failed to adequately question prospective jurors on the subject of pretrial publicity. He complains that, during the voir dire proceedings, the court declined his request for individual questioning on this topic. Instead, the court polled the members of the venire as a group, asking whether any of them believed themselves to be incapable of “put[ting] aside whatever it is that [they had] heard.” J.A. 1692. The court did call eight prospective jurors to the bench for one-on-one questioning, but only after the defense singled them out on the basis of their responses to a jury selection questionnaire. Appellant argues that such “perfunctory” questioning violated his Sixth Amendment right to an impartial jury. Appellant’s Br. 65. Because “[t]he conduct of voir dire necessarily is committed to the sound discretion of the trial court,” United States v. Lancaster, 96 F.3d 734, 738 (4th Cir.1996) (en banc), we also review this contention for abuse of discretion, see United States v. Caro, 597 F.3d 608, 613 (4th Cir.2010). Appellant’s argument begins inauspiciously, with an assertion that the Supreme Court’s decision in Skilling v. United States, 561 U.S. 358, 130 S.Ct. 2896, 177 L.Ed.2d 619 (2010), establishes minimum requirements for voir dire in “publicity-saturated” cases like this oné. Appellant’s Br. 22. In Skilling, he claims, the Court approved the voir dire procedure “only because” the trial court asked prospective jurors to indicate whether they had formed an opinion about the defendant’s guilt or innocence and later examined them individually about pretrial publicity. Id. Appellant then reasons that, because the trial court in this case took neither of those steps, it necessarily “failed to ‘provide a reasonable assurance that prejudice would be discovered if present.’ ” Id. (quoting Lancaster, 96 F.3d at 740). Skilling, however, does not purport to hand down commandments for the proper conduct of voir dire proceedings. See 130 S.Ct. at 2918 (explaining that the legal issue under review was, narrowly, “the adequacy of jury selection in Skilling’s case ” (emphasis supplied)). On the contrary, the Court in Skilling recommitted itself to the principle that jury selection is unsusceptible to any “hard-and-fast formula”; as always, it remains “particularly within the province of the trial judge.” Id. at 2917 (internal quotation marks omitted); see also United States v. Wood, 299 U.S. 123, 145-46, 57 S.Ct. 177, 81 L.Ed. 78 (1936) (stating that procedures for detecting and rooting out juror bias cannot be “chained to any ancient and artificial formula”). Trial judges, as we have repeatedly recognized, retain broad discretion over the conduct of voir dire, see, e.g., United States v. Jeffery, 631 F.3d 669, 673 (4th Cir.2011), both as a general matter and in the area of pretrial publicity, specifically, see, e.g., United States v. Bailey, 112 F.3d 758, 770 (4th Cir.1997); United States v. Bakker, 925 F.2d 728, 733-34; (4th Cir.1991). The Supreme Court has itself emphasized the “wide discretion” that trial courts enjoy in questioning prospective jurors about pretrial publicity: Particularly with respect to pretrial publicity, we think this primary reliance on the judgment of the trial court makes good sense. The judge of that court sits in the locale where the publicity is said to have had its effect and brings to his evaluation of any such claim his own perception of the depth and extent of news stories that might influence a juror. The trial court, of course, does not impute his own perceptions to the jurors who are being examined, but these perceptions should be of assistance to it in deciding how detailed an inquiry to make of the members of the jury venire. Mu’Min v. Virginia, 500 U.S. 415, 427, 111 S.Ct. 1899, 114 L.Ed.2d 493 (1991). In his opening brief, Appellant accuses the district court of “limit[ing] voir dire on this issue to asking the prospective jurors en masse to sit down if they felt they could be fair.” Appellant’s Br. 65. The court, though, did a good deal more than thát. Jury selection in this case commenced with a court-approved jury questionnaire spanning 99 questions, four of which pressed prospective jurors for information about their exposure to pretrial publicity. The questionnaire — by and large, a condensed version of a slightly longer proposed questionnaire that the parties submitted jointly — asked respondents to state whether they had “seen, heard or read anything” about the case; “[h]ow closely” they had followed news about the case; and from which types of media they had heard about it. J.A. 592-93.' It then asked whether each respondent had “expressed an opinion about this case or about those involved to anyone,” and if so, to elaborate on both “the circumstances” and the opinion expressed. Id. at 593. Appellant makes much of the fact that the jury questionnaire merely asked whether prospective jurors had “expressed” an opinion about the case, rather than whether they had formed an opinion about it. Appellant, however, bears much of the responsibility for the wording and scope of questions on that document. And while the jointly proposed jury questionnaire from which the final questionnaire was culled did, indeed, ask whether prospective jurors had “formed” an opinion about the case, the wording of this proposed question was suspect. It asked: “Based on what you have read, heard, seen, and/or overheard in conversations, please tell us what opinions, if any, you have formed about the guilt or innocence of Robert F. McDonnell.” J.A. 527. So worded, this question invites respondents to deliberate on the defendant’s guilt or innocence arid to stake out a position before even a single juror has been seated. The court was justified in rejecting it. Later, the court did exercise its discretion to question the prospective jurors as a group, instead of individually, on the subject of pretrial publicity. See Bakker, 925 F.2d at 734 (“[I]t is well established that a trial judge may question prospective jurors collectively rather than individually”). During this portion of the in-court voir dire, the court asked the members of the venire, collectively, to stand up if they had read, heard, or seen any media reports about the case. The court then asked the prospective jurors to sit down if, despite this, they believed they were “able to put aside whatever it is that [they] heard, listen to the evidence in this case and be fair to both sides.” J.A. 1691-92. Even still, the court invited defense counsel to identify any specific veniremen it would like to question further on this subject. In response, Appellant’s counsel brought forward the names of eight prospective jurors, and the court proceeded to summon each of those prospective jurors to the' bench for individual questioning. The court struck one of these individuals, without objection, based on her responses to its questions. When this process was complete, the court asked Appellant’s counsel whether there was “[a]nybody else” he wished to question. J.A. 1706. “Not on publicity,” counsel said. Id. Appellant, relying on our decision in United States v. Hankish, 502 F.2d 71 (4th Cir.1974), argues that the prospective jurors’ acknowledgment that they had been exposed to pretrial publicity obligated the trial court to question every single one of them — not merely one at a time, but outside of the others’ presence. See Appellant’s Br. 65. Hankish, however, is inapplicable. The error in that case was a district court’s refusal to poll jurors, after they had already been seated, to discern whether any of them had read a particular, “highly prejudicial” article that ran in the local newspaper on the second day of the trial. 502 F.2d at 76. We did not hold then, and have not held since, that individual questioning, out of earshot of the rest of the venire, is required to alleviate generalized concerns about the pernicious effects of pretrial publicity. On the contrary, we have held that merely asking for a show of hands was not an abuse of discretion. See Bailey, 112 F.3d at 769-70 (finding no abuse of discretion where a court asked prospective jurors to raise their hands if they had heard or read about the case and, separately, if “anything they had heard would predispose them to favor one side or the other”). We are satisfied that the trial court’s questioning in this case was adequate to “provide a reasonable assurance that prejudice would be discovered if present.” Lancaster, 96 F.3d at 740 (internal quotation marks omitted); see also United States v. Hsu, 364 F.3d 192, 203-04 (4th Cir.2004). And Appellant does not contend that any actual juror bias has been discovered. We conclude, therefore, that the court did not abuse its discretion. C. Evidentiary Rulings Appellant asserts the district court made multiple erroneous evidentiary rulings. In general, we review evidentiary rulings for an abuse of discretion, affording substantial deference to the district court. See United States v. Medford, 661 F.3d 746, 751 (4th Cir.2011). “A district court abuses its discretion if its conclusion is guided by erroneous legal principles or rests upon a clearly erroneous factual finding.” Westberry v. Gislaved Gummi AB, 178 F.3d 257, 261 (4th Cir.1999) (citations omitted). Reversal is appropriate if we have “a definite and firm conviction that the court below committed a clear error of judgment in the conclusion it reached upon a weighing of the relevant factors.” Id. (internal quotation marks omitted). 1. Exclusion of Expert Testimony Appellant objects to the exclusion of his proposed expert testimony about Williams’s cooperation agreement with the Government as well as expert testimony about the Statements of Economic Interest. We reject these claims, as the trial court’s decisions to exclude this evidence were not abuses of discretion. a. First, Appellant argues that he should have been permitted to present expert testimony about Williams’s cooperation agreement with the Government, which provided Williams with transactional immunity. In a letter dated May 30, 2014, the Government outlined the immunized conduct: (1) conduct involving his agreement to provide, and his provision of, things of value to former Virginia Governor Robert F. McDonnell, former First Lady of Virginia Maureen P. McDonnell, and their family members; (2) conduct related to loans Williams received from 2009 to 2012 in exchange for his pledge of Star Scientific stock; and (3) conduct related to Williams’ gifts of Star Scienti-fie stock to certain trusts from 2009 to 2012. J.A. 7918. Appellant offered the expert testimony of Peter White — a partner at Schulte Roth & Zabel LLP and former Assistant United States Attorney — to “ex-plaint] transactional immunity, its value, and its uniqueness” and to “help[ ] the jury understand Williams’s deal so it could assess his credibility.” Appellant’s Br. 78. Expert testimony cannot be used for the sole purpose of undermining a witness’s credibility. See United States v. Allen, 716 F.3d 98, 105-06 (4th Cir.2013). Here, the defense wished to present White’s testimony in order to emphasize the rarity of Williams’s agreement and to imply, as a result, that Williams had more reason to provide false or greatly exaggerated testimony. In other words, the sole purpose of White’s testimony was to undermine Williams’s credibility. This is a matter best left to cross examination. Accordingly, we cannot conclude that the district court’s decision to exclude this evidence was an abuse of discretion. See Allen, 716 F.3d at 106 (“A juror can connect the dots and understand the implications that a plea agreement might have on a codefendant’s testimony — it is certainly within the realm of common sense that certain witnesses would have an incentive to incriminate the defendant in exchange for a lower sentence.” (internal quotation marks omitted)). b. Second, Appellant argues that he should have been permitted to present expert testimony about the Statements of Economic Interest. Appellant offered the expert testimony of Norman A. Thomas— a private attorney who formerly worked in the Office, of the Attorney General of Virginia and served as a judge—to explain the vagueness and complexity of the Statements of Economic Interest. According to Appellant, Thomas also would have explained that Appellant’s Statements of Economic Interest evidenced a reasonable understanding of the disclosure requirements. Expert testimony must “help the trier of fact to understand the evidence or to determine a fact in issue.” Fed.R.Evid. 702(a). “The helpfulness requirement of Rule 702 thus prohibits the use of expert testimony related to matters which are obviously ... within the common knowledge of jurors.” United States v. Lespier, 725 F.3d 437, 449 (4th Cir.2013) (alteration in original) (internal quotations marks omitted). The district court excluded the testimony of Thomas because it would not be helpful to the jury. As the court observed, the jurors were “capable of reading and assessing the complexity of the [Statements] for themselves.” J.A. 719. Generally speaking, one does- not need any special skills or expertise to recognize that something is complex. Accordingly, this matter was plainly within the common knowledge of the jurors. Similarly, the jurors did not need expert assistance to assess the reasonableness of Appellant’s opinions about what he did and did not have to disclose. The district court reasonably concluded that Thomas’s testimony would not have been helpful. As a result, we cannot conclude that the district court’s decision to exclude this evidence was an abuse of discretion. 2. Admission of Statements of Economic Interest Appellant objects to the admission of the Statements of Economic Interest filed by Appellant during his time in office. Appellant moved in limine to exclude evidence relating to the Statements of Economic Interest, arguing the Statements of Economic Interest would have little to no probative value and their admission would confuse the issues and mislead the jury. The Government, on the other hand, characterized the Statements of Economic Interest and related evidence as concealment evidence, which would reveal Appellant’s “corrupt intent and consciousness of guilt.” J.A. 723. In support of this proposition, the Government offered four examples of how the Statements of Economic Interest amounted to concealment evidence: [F]irst, because of [Appellant’s] deliberate omission of his golf-related gifts paid by Jonnie Williams; second, because of [Appellant’s] deliberate omission of the $15,000 check from Mr. Williams to pay the remainder of the catering bill the McDonnells owed for their daughter’s wedding; third, as the reason why Mrs. McDonnell sold and repurchased all Star stock held in her account on dates flanking the due date for [Appellant’s] 2011 [Statement of Economic Interest], and why the next year, she similarly unloaded Star stock to [Appellant’s] children on December 26, 2012, such that less than $10,000 worth of Star stock remained in her account at year-end; and fourth, as the reason why [Appellant] had Mr. Williams direct $70,000 in loan proceeds to [Mobo]. Id. at 723-24 (citations omitted). Evidence is relevant if “it has any tendency to make a fact more or less probable than it would be without the evidence” and “the fact is of consequence in determining the action.” Fed.R.Evid. 401(a)-(b). Relevant evidence may be excluded “if its probative value is substantially outweighed by a danger of ... unfair prejudice, confusing the issues, misleading the jury, undue delay, wasting time, or needlessly presenting cumulative evidence.” Id. 403. The district court admitted the Statements of Economic Interest because they were relevant “to concealment and may be probative of intent to defraud” and because “admission ... will not unfairly prejudice [Appellant] because there is no suggestion, and there will be none at trial, that [Appellant] violated Virginia’s ethics laws or reporting requirements.” J.A. 760. Indeed, an attempt to conceal actions may indicate an individual has a guilty conscience or is aware of the unlawfulness of the actions. See United States v. Zayyad, 741 F.3d 452, 463 (4th Cir.2014). Because the Statements of Economic Interest did not include various gifts, stock transactions, and loans from Williams to Appellant — omissions Appellant sought to explain during trial — the structuring of the loans and gifts and failures to report could be seen as efforts to conceal Appellant’s dealings with Williams. The district court correctly observed as much. And the district court weighed the probative value of this evidence against any dangers that would accompanying its admission. Accordingly, we cannot conclude that the district court’s decision to admit this evidence was an abuse of discretion. 3. Admission of Other Gifts Evidence Appellant objects to the admission of evidence that he accepted a gift of the Kiawah vacation from Goodwin and that he did not disclose this gift pursuant to the “personal friend” exception to Virginia’s reporting requirements. Appellant moved in limine to exclude this evidence as extrinsic evidence of unrelated alleged acts with no probative value of his intent. The Government responded that this evidence showed Appellant’s knowledge of the “personal friend” exception to reporting requirements. This evidence, the Government further noted, would be “competent evidence of absence of mistake or lack of accident when it comes to assessing [Appellant’s] intent in failing to disclose the gifts and loans from Mr. Williams.” J.A. 731. As a general rule, “[e]vidence of a crime, wrong, or other act is not admissible to prove a person’s character in order to show that on a particular occasion the person acted in accordance with the character.” Fed.R.Evid. 404(b)(1). However, such evidence “may be admissible for another purpose, such as proving motive, opportunity, intent, preparation, plan, knowledge, identity, absence of mistake, or lack of accident.” Id. 404(b)(2). The district court admitted the evidence of the Kiawah vacation omission because it was used to show knowledge and lack of mistake. The omission of the gift from Goodwin, the district court determined, “is similar to the act the Government seeks to prove — omission of gifts from Williams pursuant to the personal friend exception.” J.A. 761. This evidence established that Appellant knew about the “personal friend” exception and omitted certain gifts pursuant to this exception. Thus, Appellant’s knowledge and the absence of mistake was “relevant to, and probative of, his alleged intent to defraud.” Id. Rule 404 permits the admission of evidence of intent and knowledge, and in our view, the district court could conclude that the Goodwin evidence was admissible for these purposes. Therefore, we cannot conclude that the district court’s decision to admit this evidence was an abuse of discretion. 4. Admission of Email Exchange Regarding Free Golf Appellant objects to the admission of an email exchange about obtaining free rounds of golf. On January 4, 2013, Emily Rabbitt — Appellant’s travel aide and deputy director of scheduling — asked Adam Zu-bowsky for advice about planning golf trips for Appellant. Zubowsky — once Appellant’s travel aide and later Appellant’s son-in-law — responded in an email dated January 4, 2013: Yes basically this means find out who we know in these cities, that owns golf courses and will let me and my family play for free, or at a reduced cost. Also finding out where to stay for free / or reduced cost. So this means ... find out about pac donors, and rga donors, who will host rfm. J.A. 7921. During trial, Appellant objected to the admission of this email, asserting that this evidence was not relevant and was extraordinarily prejudicial. In post-trial motions and on appeal, however, Appellant has claimed the exchange was inadmissible hearsay and inadmissible character evidence. Because Appellant did not object at trial on these grounds, our review is for plain error. See United States v. Bennett, 698 F.3d 194, 200 (4th Cir.2012). On plain error review, an appellant “bears the burden of establishing (1) that the district court erred; (2) that the error was plain; and (3) that the error affect[ed his] substantial rights.” Bennett, 698 F.3d at 200 (alteration in original) (internal quotation marks omitted). An error affects an individual’s substantial rights if it was prejudicial, “which means that there must be a reasonable probability that the error affected the outcome of the trial.” United States v. Marcus, 560 U.S. 258, 130 S.Ct. 2159, 2164, 176 L.Ed.2d 1012 (2010). The mere possibility that the error affected the outcome of the trial does not establish prejudice. See id. “Even then, this court retain[s] discretion to deny relief, and denial is particularly warranted where it would not result in a miscarriage of justice.” Bennett, 698 F.3d at 200 (alteration in original) (internal quotation marks omitted). At first, the district court refused to permit discussion of the particular email exchange when it was mentioned during the testimony of Rabbitt. Later in the trial, during cross examination of Appellant, the email exchange was admitted over Appellant’s relevancy objection. The discussion of the exchange focused on whether Appellant received information about golf courses where he could play for free or at a reduced cost. Upon review of the record, it does not appear that this exchange was mentioned again, and the parties have not identified any other discussion of the exchange. The use of the email exchange was quite limited, especially in light of the voluminous evidence presented during the course of the five weeks of trial. We cannot say there is a reasonable probability that its admission affected the outcome of the trial. The indictment, we note, did not seek to prosecute Appellant for this conduct; indeed, the district court instructed the jury that Appellant was “not on trial for any act or conduct or offense not alleged in the indictment.” J.A. 7695. We presume the jurors followed the district court’s instruction. See, e.g., Weeks v. Angelone, 528 U.S. 225, 234, 120 S.Ct. 727, 145 L.Ed.2d 727 (2000). Accordingly, the claim that evidence of the email exchange affected the outcome of the trial is beyond the realm of reasonable probability. The admission of this evidence was not plainly erroneous. 5. Return of Forensic Image of Williams’s iPhone Appellant also asserts the district court erroneously ordered him to return all copies of a forensic image of Williams’s iPhone, which the Government had produced to Appellant pursuant to Rule 16 of the Federal Rules of Criminal Procedure. Appellant’s chief complaint is that the forensic image may contain evidence to which he is entitled pursuant to Brady v. Maryland, 373 U.S. 83, 83 S.Ct. 1194, 10 L.Ed.2d 215 (1963), and Giglio v. United States, 405 U.S. 150, 92 S.Ct. 763, 31 L.Ed.2d 104 (1972). However, Appellant waives this claim because his treatment of it is conclusory. Appellant merely argues: “If [Appellant] receives a new trial, he is entitled to this evidence, which almost certainly contains Brady and Giglio material. Likewise, if any of that evidence proves material, its confiscation requires a new trial.” Appellant’s Br. 85 (citations omitted). Appellant’s argument includes bare citations to two decisions of little obvious relevance from other courts of appeals. Furthermore, Appellant does not make any effort to establish the elements of a Brady or Giglio violation. See Strickler v. Greene, 527 U.S. 263, 281-82, 119 S.Ct. 1936, 144 L.Ed.2d 286 (1999) (“The evidence at issue must be favorable to the accused, either because it is exculpatory, or because it is impeaching; that evidence must have been suppressed by the State, either willfully or inadvertently; and prejudice must have ensued.”). Summary treatment of a claim does not sufficiently raise the claim. See, e.g., Russell v. Absolute Collection Servs., Inc., 763 F.3d 385, 396 n. * (4th Cir.2014) (noting that failure to present legal arguments and “record citations or pertinent legal authority supporting ... a claim” waives the claim). Although Appellant raised this issue in an interlocutory appeal in a related case — an appeal we dismissed for want of jurisdiction — this does not preserve the issue and is not sufficient to raise the issue now. To avoid waiver, a party must brief the issue in an appeal over which we may exercise jurisdiction. Thus, because Appellant fails to sufficiently raise this issue and has, therefore, effectively waived it, we do not further address it. III. With these matters resolved, we turn to the two arguments at the core of this appeal. First and foremost, Appellant asserts that the district court’s jury instructions misstated fundamental principles of federal bribery law. Second, he asserts that the Government’s evidence was insufficient to support his convictions pursuant to the honest-services wire fraud statute and the Hobbs Act. We address each of these contentions in turn. A. Jury Instructions Appellant’s claim with respect to the jury instructions is that the court defined bribery far too expansively. “We review de novo the claim that a jury instruction failed to correctly state the applicable law.” United States v. Jefferson, 674 F.3d 332, 351 (4th Cir.2012). “[W]e do not view a single instruction in isolation, but instead consider whether taken as a whole and in the context of the entire charge, the instructions accurately and fairly state the controlling law.” United States v. Woods, 710 F.3d 195, 207 (4th Cir.2013) (internal quotation marks omitted). Even if, upon review, we find that the court misinstruct-ed the jury on an element of an offense, we may disregard the error as harmless. See United States v. Cloud, 680 F.3d 396, 408 n. 5 (4th Cir.2012); United States v. Ramos-Cruz, 667 F.3d 487, 496 (4th Cir.2012). “We find an error in instructing the jury harmless if it is ‘clear beyond a reasonable . doubt that a rational jury would have found the defendant guilty absent the error.’ ” Ramos-Cruz, 667 F.3d at 496 (quoting Neder v. United States, 527 U.S. 1, 18, 119 S.Ct. 1827, 144 L.Ed.2d 35 (1999)). 1. We begin our analysis with an examination of the statutes of conviction. The first of these is the honest-services wire fraud statute, 18 U.S.C. §§ 1343, 1346. This statute requires the Government to prove that the defendant sought to “carry out a ‘scheme or artifice to defraud’ another of ‘the-intangible right of honest services.’” United States v. Terry, 707 F.3d 607, 611 (6th Cir.2013) (citations omitted) (quoting 18 U.S.C. §§ 1341, 1346). The Supreme Court has recognized that § 1346 proscribes two, and only two, types of activities: bribery and kickback schemes. See Skilling v. United States, 561 U.S. 358, 130 S.Ct. 2896, 2907, 177 L.Ed.2d 619 (2010). To the extent that the statute prohibits acts of bribery, the prohibition “draws content ... from federal statutes proscribing — and defining— similar crimes,” including the general federal bribery statute, 18 U.S.C. § 201(b), and the statute prohibiting theft and bribery involving federal funds, 18 U.S.C. § 666(a)(2). Skilling, 130 S.Ct. at 2933. Here, in their proposed instructions for honest-services wire fraud, both parties sought to import the definition of bribery set forth in 18 U.S.C. § 201(b)(2). This statute provides that public officials may not “corruptly” demand, seek, or receive anything of value “in return for ... being influenced in the performance of any official act.” 18 U.S.C. § 201(b)(2). The statute defines an “official act” as “any decision or action on any question, matter, cause, suit, proceeding or controversy, which may at any time be pending, or which may by law be brought before any public official, in such official’s official capacity, or in such official’s place of trust or profit.” Id. § 201(a)(3). The district court provided a near-verbatim recitation of these provisions in its honest-services wire fraud instructions. A second statute of conviction in Appellant’s case, the Hobbs Act, prohibits acts of extortion which “in any way or. degree obstruct[ ], delay[ ], or affect[ ] commerce or the movement of any article or commodity in commerce.” 18 U.S.C. § 1951(a). Though a defendant may commit extortion through threats or violence, it is also possible to commit extortion by obtaining property “under color of official right.” Id. § 1951(b)(2). In Evans v. United States, the Sup
