HULL, Circuit Judge: After a jury trial, eight defendants— seven individuals and one corporation— appeal various aspects of their convictions and sentences in connection with the operation of a complex and sustained scheme of Medicare fraud. To begin, we recount certain evidence regarding the fraud scheme and outline the proceedings before the district court. We then review, with relevant factual background, the appellants’ challenges to their convictions and sentences. I. THE FRAUD SCHEME A. Biscayne Milieu Health Center In 1996, Biscayne Milieu Health Center, Inc. (“Biscayne Milieu”), located in North Miami, was incorporated in Florida. It offered a partial hospitalization program (“PHP”) for patients with mental illness. In 1997, Biscayne Milieu was certified as a Community Mental Health Center; it received a provider number allowing it to bill Medicare for PHP treatment. A PHP provides intensive outpatient treatment for patients with acute mental illness who are sufficiently ill that they would otherwise require inpatient hospitalization. Medicare covers partial hospitalization programs providing treatment for mental illness, but only does so subject to a variety of conditions. These Medicare rules and regulations are set forth in the Local Coverage Determination (“LCD”). Medicare requires that, to qualify for the PHP benefit, the services must be reasonable and necessary for the diagnosis and active treatment of the patient’s condition. The LCD makes clear that PHPs are structured to “provide patients with profound or disabling mental health conditions an individualized, coordinated, intensive, comprehensive, and multidisciplinary treatment program not provided in a regular outpatient setting.” A given patient must be experiencing “an acute onset or decompensation of a covered Axis I mental disorder,” severe enough to prevent the patient from functioning in normal daily activities outside of a hospital setting. And there must also be a reasonable expectation that active treatment in the PHP will improve the patient’s condition. Patients should not remain in PHPs indefinitely. Further, dual diagnosis patients are those suffering from both substance abuse and acute mental disorders. Under Medicare’s regulations, dual diagnosis patients may be eligible for PHP treatment. But PHP treatment is not authorized for “individuals with persistent substance abuse” who “cannot or refuse to participate with active treatment of their mental disorder.” An addicted individual may be admitted as long as the individual is not actively using the substance at the time of admission and has an acute mental health crisis. For a patient to be admitted to a PHP, a “psychiatrist or physician trained in the diagnosis and treatment of psychiatric illness” must certify that the patient would require in-patient psychiatric hospitalization if the PHP services were not provided, and must attest that the services will' be furnished while the patient is under the care of a physician and pursuant to an individualized plan of care. Once a patient is enrolled in a PHP, Medicare requires documentation supporting the medical necessity of the claims made by the PHP provider. This documentation includes progress notes detailing the patient’s participation in and response to the intensive treatment. Partial hospitalization in a PHP is a very intensive and expensive form of treatment for patients experiencing an acute mental health crisis. The evidence showed that Biscayne Milieu was paid $165 per patient per day for outpatient treatment or approximately $5000 per month per patient. The owners and operators of Biscayne Milieu — the appellants here — agreed to be bound by these rules and regulations and to refrain from filing false claims. Because of the volume of claims processed by Medicare, the candor and truthfulness of the appellants, as health care providers making claims into the system, are absolute necessities. As is too often the case, the appellants here concocted and engaged in a pernicious scheme to defraud Medicare and preyed upon vulnerable victims. To carry out the scheme, the owners and operators of Biscayne Milieu: (a) submitted false and fraudulent claims to Medicare for PHP services for patients who were not eligible for PHP treatment, for PHP services that were not medically necessary, for PHP services that were not eligible for Medicare reimbursement, and for PHP services that were not actually provided by Biscayne Milieu; (b) offered, paid, or received kickbacks and bribes for recruiting Medicare beneficiaries to attend Biscayne Milieu; (c) paid kickbacks and bribes to patients to ensure the attendance of ineligible Medicare beneficiaries at Biscayne Milieu; (d) concealed the submission of false and fraudulent claims to Medicare, the receipt and transfer of the proceeds from the fraud, and the payment of kickbacks and bribes to patient recruiters and Medicare beneficiaries; and (e) diverted proceeds of the fraud for personal use. Further, Biscayne Milieu employees and agents, including a doctor, therapists, nurses, and social workers, implemented the fraud by admitting ineligible patients to Biscayne Milieu, holding therapy sessions for patients who did not qualify for PHP treatment, falsifying group therapy notes to justify fraudulent claims to Medicare, and recruiting Haitian patients who did not qualify for PHP treatment by promising to assist such patients with applications for United States citizenship. At trial, numerous former employees of Biscayne Milieu, many of whom were separately indicted and had previously pled guilty to their participation in the fraud scheme, offered substantial evidence of the scheme’s scope and design. From 2007 to 2011, Biscayne Milieu submitted $57,689,700 in Medicare claims for PHP care of mentally ill patients, and Medicare paid $11,481,593 on those claims. This billing was largely fraudulent for the simplest of reasons. Virtually all of the patients treated at Biscayne Milieu’s PHP were not suffering an acute onset of a covered Axis I mental disorder; did not have a reasonable expectation of improvement as a result of PHP treatment; or were not cognitively able to participate in PHP treatment. As the district court found, even the few patients who might have had such an acute mental disorder did not receive the medical care that was required under the PHP rules. Rather than eligible PHP patients, the patient population principally fell into four categories: (1) chronic substance abusers; (2) elderly patients with dementia; (3) Haitian patients seeking immigration benefits; and (4) paid patients. Chronic substance abusers constituted an enormous percentage of the patient population at Biscayne Milieu. Trial witnesses testified that between 70 percent and 96 percent of Biscayne Milieu patients were chronic substance abusers. By virtue of their chronic substance abuse and lack of an acute mental disorder, the patients at Biscayne Milieu were, for the most part, not eligible for PHP treatment at all. Even though it was regularly admitting substance abusers, Biscayne Milieu also failed to provide meaningful treatment for substance abuse. In short, during the relevant period, Biscayne Milieu operated a patient mill supported by a kickback scheme that ensured an ongoing supply of patients. The kickback scheme itself was highlighted by the use of what the parties often referred to as the “money sheet.” The money sheet included columns for: the patient’s name; the physician responsible for admitting the patient into the PHP; the initials of the person who referred the patient; and a box for each day of the month. Biscayne Milieu billed Medicare, and paid the recruiter, for each day that had an “X” in the box, which showed that the patient attended therapy that day. Recruiters were paid only for days the patient attended therapy, and they were not paid for any days that the patient was absent. B. The Seven Individual Defendants In addition to the corporate defendant Biscayne Milieu, the seven individual defendants appealing here played various roles in the operation of the fraud scheme. Defendant Antonio Macli was Biscayne Milieu’s chief executive officer (“CEO”). He also served as Biscayne Milieu’s primary contact with Medicare for purposes of provider certification. Defendant Antonio Macli certified compliance with Medicare rules and regulations despite clear knowledge that Biscayne Milieu’s patient inventory had been stocked through the payment of illegal recruiter kickbacks. He also directed these recruiters to expand their efforts, including by recruiting patients from outside the state, and he ensured that recruiters masked the nature of their employment via false case management contracts. Defendant Antonio Macli also instructed recruiters to recruit Haitian patients to attend the PHP, even though such patients did not qualify for PHP treatment. At trial, former employees of Biscayne Milieu testified to defendant Antonio Mac-li’s control over the operation. Former therapist Nikki Charles testified that Antonio Macli stated that it was “his business” and that he was “in charge,” further adding, when disputes arose, that there were “too many chiefs and not enough [I]ndians.” Recruiter James Edwards testified that he was hired as a recruiter by Antonio Macli with the explicit understanding that he would be paid $25 per client per day of treatment. Former therapist Manotte Bazile testified that Antonio Macli offered her $1000 in addition to her salary if she would recruit patients from the Haitian community. A government agent testified that Antonio Macli signed the checks on behalf of Biscayne Milieu that went to patient recruiters. And John Jackson, the former clinical director of Biscayne Milieu, testified that Antonio Macli signed the check that was cashed to pay off a patient who threatened to expose the fraud. Defendant Antonio Macli’s son, defendant Jorge Macli, was the day-to-day manager of Biscayne Milieu and also a designated point of contact for Medicare. Both Antonio Macli and Jorge Macli had an ownership interest in Biscayne Milieu as well as managerial control of the company. In his day-to-day management role, defendant Jorge Macli oversaw almost every significant aspect of the fraud. He had ultimate oversight over the patient recruiters. He himself recruited patient recruiters and then paid kickbacks to those recruiters. In addition, Jorge Macli aided patient recruiters in financing the purchasing or lease of halfway houses used to board the patients recruited to attend the PHP at Biscayne Milieu. In 2010, defendant Jorge Macli initiated the plan to have the patient recruiters sign fraudulent “case manager” contracts and insisted that recruiters, including defendants Derek Alexander and Anthony Roberts, do so. He directed the recruiters to submit false invoices. Defendant Jorge Macli even paid hush money to certain patients to quiet their complaints. Defendant Jorge Macli directed the admission of patients he knew to be ineligible for PHP treatment, even over complaints from other staff. He overrode staff attempts to deny admissions to elderly patients with dementia who were recycled from other PHPs and Haitian patients who were not mentally ill and who came to Biscayne Milieu in order to obtain immigration benefits. Multiple witnesses testified to defendant Jorge Macli’s centrality to the fraud scheme. Former clinical director John Jackson testified that defendant Jorge Macli agreed, during Jackson’s hiring process, to pay Jackson $25 per day per client attending Biscayne Milieu. Further, Jackson testified to two details showing defendant Jorge Macli’s clear awareness of the fraudulent nature of the enterprise. First, Jackson and Jorge Macli agreed that patients Jackson would recruit from another, then-closed facility should enter Biscayne Milieu over time rather than all at once to avoid suspicion of the Medicare billing. Second, concerned about how Jackson would account for the additional income, Jorge Maeli suggested that Jackson be paid for the recruiting via a dummy corporation or under a different individual’s name to avoid suspicion regarding Jackson’s fluctuating paycheck. Jackson also testified that Jorge Maeli agreed to loan Jackson, as well as other recruiters, funds to expand halfway houses which would then send their residents for PHP treatment at Biscayne Milieu. Separately, Rufus Cargile, who began as a patient at Biscayne Milieu but was later hired as a mental health worker, was sent to Detroit, Michigan, by defendant Jorge Maeli for the purpose of recruiting substance abuse patients to Biscayne Milieu. Cargile testified that Jorge Maeli paid for the trip to Detroit, where Cargile was from, with the expectation that Cargile would “do marketing for Jorge [Maeli] and Biscayne Milieu.” Referring specifically to the value of additional patients recruited, Cargile testified that Jorge Maeli said, “I get two. You get one.” Cargile further testified that marketing in Detroit was viewed as effective because of the limited set of treatment options available for Medicare patients seeking drug treatment. And, like his father Antonio Maeli, defendant Jorge Maeli also signed checks payable to the recruiters. Defendant Antonio Macli’s daughter, defendant Sandra Huarte, was in charge of Biscayne Milieu’s Medicare billing and Biscayne Milieu’s payroll. In this capacity, defendant Huarte oversaw and administered Biscayne Milieu’s payment of illegal kickbacks to patient recruiters. Defendant Huarte also had the “money sheets” in her office, which she used to calculate the recruiter kickbacks. Further, recruiter James Edwards testified to defendant Huarte’s possession of the “money sheets.” In addition, defendant Huarte instructed patient recruiters to recruit Haitian patients to attend the PHP who were not mentally ill and were not qualified for PHP treatment. Defendant Huarte also paid therapists to falsify group therapy notes and was aware of numerous other fraudulent practices at Biscayne Milieu. Therapist Manotte Bazile testified that defendant Huarte, on more than one occasion, requested that Bazile fill out falsified group notes and then paid Bazile, by hand-delivered check, in excess of her salary, when the notes were completed. Defendant Huarte also served as CEO of North Biscayne Investment, Inc., a separate vehicle for transferring the proceeds of the health care fraud to defendants Antonio Maeli and Huarte. Several North Biscayne Investment bank accounts were involved in the transfer of fraudulent Medicare proceeds. Defendant Huarte used the bank accounts to transfer fraudulent Medicare proceeds to herself and others. From late 2008 through 2011, defendant Dr. Gary Kushner, a medical doctor licensed in Florida, was an attending physician at Biscayne Milieu and one of its main psychiatrists. Dr. Kushner signed forms and charts authorizing treatment for patients who were not eligible for PHP treatment, often without examining the patients or the charts. He authorized Biscayne Milieu to bill Medicare using his Medicare identifier as an attending physician to legitimate the fraudulent claims. Dr. Kush-ner admitted numerous patients he himself referred from local hospitals and also did so working in concert with patient recruiters. To hide the fact that such patients were chronic substance abusers, Dr. Kush-ner excluded substance-abuse issues from patient diagnoses. Following admission, Dr. Kushner met with patients only briefly, for five to ten minutes. He had minimal interaction with the patients. He conducted the meetings merely to justify the creation of records that made it appear as though he was providing meaningful treatment. Dr. Kushner also signed forms that falsely certified he had conducted reviews of Biscayne Milieu billings and had discovered no fraudulent billings. These forms certified that Dr. Kushner had “conducted a systematic review of clinic billing to ensure that the billings [were] not fraudulent or unlawful” and that Dr. Kushner had not “discovered any unlawful charges.” In addition to falsifying these documents, Dr. Kushner authorized other staff to complete his paperwork and sign documents for him. Defendant Huarte eventually obtained Dr. Kushner’s electronic password in order to sign treatment plans for him. Defendant Rafael Alalu, a licensed mental health counselor in Florida, became the clinical director at Biscayne Milieu in late June 2010 after serving as a part-time therapist on the Biscayne Milieu staff since February 2010. He remained at Biscayne Milieu until his arrest in September 2011. Evidence at trial showed that defendant Alalu was clearly aware of the variety of patients improperly admitted to Biscayne Milieu. Alalu oversaw the work of mental health therapists and social workers, falsified numerous group therapy notes, and created false notes for patients who were not ill, never showed up, left sessions early, or who were not eligible or did not qualify for PHP treatment in the first place. Further, Alalu cut and pasted therapy notes from one patient into the files of other patients and knowingly oversaw other therapists doing so. At trial, the government introduced approximately 87 sets of therapy notes containing two or more notes that Alalu simply copied and pasted. In one example, Alalu created notes for seven patients on one date and, five weeks later, Alalu copied and pasted the information from those notes into identical notes for seven completely different patients. Alalu also encouraged the creation of fraudulent records by other therapists. Defendant Derek Alexander and defendant Anthony Roberts each served as patient recruiters for Biscayne Milieu. Both Antonio Macli and Jorge Macli hired recruiters and authorized the payment of kickbacks. And Dr. Kushner steered the patients he treated at local hospitals to Roberts and some of the other recruiters, who would then compete to get credit for the clients. From March 2010 through February 2011, defendant Alexander was a patient recruiter and Biscayne Milieu paid him $30 per patient per day for the referred patients’ attendance. He received $47,500 in illegal kickbacks. From April 2008 through June 2011, defendant Roberts was a patient recruiter, and Biscayne Milieu paid him $30 per patient per day for the referred patients’ attendance. He received $199,239.48 in illegal kickbacks. Both Alexander and Roberts also created fraudulent invoices for purported case management services to Biscayne Milieu at a rate of $50 per hour, but the evidence showed that the payments to Alexander and Roberts were for patient recruiting and patient attendance at Biscayne Milieu, not for case management services. In fact, defendants Alexander and Roberts had no training or work experience in case management services. Many of Alexander’s and Roberts’s recruited patients had chronic substance-abuse problems, had been admitted to hospitals after a serious relapse, and lived as tenants in privately run halfway houses for substance abusers. Roberts operated a halfway house and collected rent from his tenants, in addition to receiving illegal kickbacks from Biscayne Milieu. For example, Roberts’s clientele included sixteen individuals who had multiple admissions to Biscayne Milieu, including one patient with five admissions and five billings to Medicare. Roberts also recruited other patient recruiters (including Wyatt Barnfield and Gregory Murphy, who were both separately indicted and who both pled guilty). Biscayne Milieu billed $750,300 to Medicare for defendant Alexander’s recruited patients and collected $300,876.08. Biscayne Milieu billed $4,866,100 to Medicare for defendant Roberts’s recruited patients and collected $887,085.31. C. The Indictment In June 2012, a federal grand jury returned a 44-count superseding indictment charging the eight appellants in this case, along with three additional co-defendants, with various offenses related to Biscayne Milieu’s submission of fraudulent Medicare claims. The three co-defendants, not on appeal here, are Curtis Gates, Madeline Lucas, and Jacqueline Moran. Count 1 alleged a four-and-a-half year conspiracy to commit health care fraud under 18 U.S.C. § 1347, from January 2007 through August 2011, in violation of 18 U.S.C. § 1349. Seven individual defendants, Antonio Macli, Jorge Macli, Huarte, Dr. Kushner, Alalu, Moran, Lucas, and corporate defendant Biscayne Milieu were charged in count 1. Counts 2 through 14 charged substantive health care fraud, in violation of 18 U.S.C. §§ 1347 and 2. Six individual defendants, Antonio Macli, Jorge Macli, Huarte, Dr. Kushner, Alalu, Moran, and corporate defendant Biscayne Milieu were charged in counts 2 through 14. Count 15 charged conspiracy to receive and pay health care kickbacks to recruiters to induce referrals of patients in connection with a federal health care program as prohibited by 42 U.S.C. § 1320a-7b(b)(l) and (2), in violation of 18 U.S.C. § 371. Six individual defendants, Antonio Macli, Jorge Macli, Huarte, Aexander, Roberts, Gates, and corporate defendant Biscayne Milieu were charged in count 15. Counts 16 through 26 charged the substantive payment of specific kickbacks to recruiters to induce patient referrals on dates ranging from August 2007 until June of 2011, in connection with a federal health care program, in violation of 42 U.S.C. § 1320a-7b(b)(2)(A). Counts 27 through 29 charged the substantive receipt of specific kickbacks by recruiters in return for patient referrals, on 15 August 2007, 4 April 2010, and 6 June 2010, in connection with a federal health care program, in violation of 42 U.S.C. § 1320a-7b(b)(l)(A). Two individual defendants, Antonio 'Macli and Jorge Macli, were charged in counts 16 through 26. Three individual defendants, Aexander, Roberts, and Gates, were charged in counts 27 through 29. Count 30 charged conspiracy to commit money laundering, in violation of 18 U.S.C. § 1956(h). Counts 31 through 37 charged money laundering, in violation of 18 U.S.C. § 1957. Counts 38 through 44 charged “concealment” money laundering, in violation of 18 U.S.C. § 1956(a)(l)(B)(i). Three individual defendants, Antonio Macli, Jorge Macli, and Huarte, were charged with counts 30 through 44. II. DISTRICT COURT PROCEEDINGS A. Jury Trial On July 2, 2012, after extensive pre-trial proceedings, all eight appealing defendants proceeded to a jury trial. On July 9, 2012, after a jury was selected and sworn, trial commenced with opening statements. The trial lasted over seven weeks, until August 24, 2012. Both pre-trial and during the trial, the district court ruled that an objection by one defendant would be adopted automatically by each defendant unless a defendant opted out of the objection. As to the 44 counts charged, the defendants moved for judgments of acquittal during trial. The district court granted these motions as to counts 9, 10, 13, 14, 38-40, and 42 and denied them as to the other counts. The remaining counts were decided by the jury. For clarity in our analysis below, we catalog here the jury verdict as against each defendant along with the sentences later imposed by the district court. B. The Convictions and Sentences Defendant Antonio Macli, the CEO of Biscayne Milieu, was convicted of counts 1, 7, 15-26, and 30-37, and acquitted of counts 2-6] 8, 11-12. He was sentenced to a total of 360 months’ imprisonment as follows: 120 months as to each of counts 1, 7, and 31 through 37, to run concurrently; 60 months as to each of counts 15 through 26, to run concurrently; and 240 months as to count 30, to run consecutively to the terms imposed on the other counts. Defendant Jorge Macli, Biscayne Milieu’s day-to-day manager and the contact person for Medicare, was convicted of counts 1, 4, 7, 15-26, 30, 32-33, 35, and 37, and acquitted of counts 2-3, 5-6, 8, and 11-12. He was sentenced to a total of 300 months’ imprisonment as follows: 60 months as to each of counts 1, 4, 7, 15-26, 32, 33, 35, and 37, to run concurrently, and 240 months as to count 30, to run consecutively to the terms imposed on the other counts. Defendant Huarte, responsible for' Biscayne Milieu’s Medicare billing and payroll, was convicted of counts 1, 2, 4-8, 11, 15, 30-31, and 34, and acquitted of counts 3 and 12. She was sentenced to a total of 262 months’ imprisonment as follows: 22 months as to each of counts 1, 2, 4-8, 11, 15, 31, and 34, to run concurrently, and 240 months as to count 30, to run consecutively to the terms imposed on the other counts. Corporate defendant Biscayne Milieu was convicted of counts 1, 2-8, 11-12, and 15, and sentenced to a one year term of probation as to each count, to run concurrently. The court also ordered defendants Antonio Macli, Jorge Macli, Huarte, and Biscayne Milieu to pay $11,481,593.43 in joint and several restitution. Defendant Dr. Kushner, Biscayne Milieu’s attending physician, was convicted of counts 1 and 2. He was sentenced to a total of 144 months’ imprisonment as follows: 120 months’ imprisonment as to count 1, and 24 months’ as to count 2, to run consecutively. Dr. Kushner was also ordered to pay $9,341,767.24 in restitution. Defendant Alalu, Biscayne Milieu’s clinical director, was convicted of counts 1 and 3-4, but acquitted on count 11. He was sentenced to concurrent terms of 100 months’ imprisonment as to each count of conviction. Alalu was also ordered to pay $5,614,353.20 in restitution. Defendant Alexander, a patient recruiter, was convicted of counts 15 and 28. He was sentenced to concurrent terms of 42 months’ imprisonment as to each count of conviction; Alexander was also ordered to pay $300,876.08 in restitution. Finally, defendant Roberts, a patient recruiter, was convicted of counts 15 and 29. He was sentenced to 60 months as to count 15, and 27 months as to count 29, to run consecutively. Roberts was also ordered to pay $887,085.31 in restitution. All eight defendants filed timely notices of appeal. III. ISSUES AND STANDARDS OF REVIEW Given the number of defendants and overlapping claims, we list here the issues raised in this appeal and the standard of review applicable to each claim: 1) Whether sufficient evidence supports the eonvictidns of six defendants, Antonio Macli, Jorge Macli, Huarte, Dr. Kushner, Alexander, and Biscayne Milieu. This Court reviews de novo whether there is sufficient evidence to support the jury’s guilty verdicts, reviewing the evidence in the light most favorable, to the government and resolving all reasonable inferences and credibility evaluations in favor of the verdict. United States v. Doe, 661 F.3d 550, 560 (11th Cir.2011). 2) Whether count 1, conspiracy to commit health care fraud, and count 15, conspiracy to receive and pay health care kickbacks, are multiplicitous. We review defendants’ preserved challenges to the indictment de novo. United States v. Woods, 684 F.3d 1045, 1060 n. 14 (11th Cir.2012). Under Federal Rule of Criminal Procedure 12, challenges to the indictment not raised before trial are waived. Fed.R.Crim.P. 12(b)(3)(B). 3) Whether the district court abused its discretion by declining to remove a juror because of an offensive comment made by .defendant Alexander’s attorney, and by subsequently denying a defense motion, made by Dr. Kushner’s attorney, for mistrial on that ground. Separately, whether defendant Alexander was denied effective assistance of counsel when his attorney failed to withdraw after making that comment. This Court reviews a district court’s decision on whether to remove a sitting juror for abuse of discretion. United States v. Register, 182 F.3d 820, 839 (11th Cir.1999). The claim of ineffective counsel presents a mixed question of law and fact and therefore receives de novo review. Dell v. United States, 710 F.3d 1267, 1272 (11th Cir.2013). 4) Whether the district court abused its discretion by admitting lay testimony regarding the eligibility of patients to receive PHP treatment, and the authenticity of Dr. Kush-ner’s signature on patient records. The district court’s evidentiary rulings, including the admission of witness testimony under Federal Rule of Evidence 701, are reviewed for abuse of discretion. United States v. Hill, 643 F.3d 807, 840-41 (11th Cir.2011). 5) Whether the district court abused its discretion by denying defendant Jorge Macli’s motion for mistrial based on a government witness’s reference to the invocation of Jorge Macli’s right to counsel. This Court reviews for abuse of discretion the denial of a mistrial motion based on a comment regarding a defendant’s right to counsel. See United States v. Reeves, 742 F.3d 487, 504 (11th Cir.2014). 6) Whether all appellants are entitled to a new trial based on remarks made by the prosecutor during rebuttal closing argument. This Court reviews de novo allegations of prosecutorial misconduct in closing argument. United States v. Eckhardt, 466 F.3d 938, 947 (11th Cir.2006). 7) Whether the omission of a jury instruction defining “attempt” is plain error. Because this issue is raised for the first time on appeal, we review it for plain error. United States v. Lewis, 492 F.3d 1219, 1221-22 (11th Cir.2007) (en banc). Under the plain error standard, “before an appellate court can correct an error not raised at trial, there must be (1) error, (2) that is plain, and (3) that affects substantial rights.” United States v. McKinley, 732 F.3d 1291, 1296 (11th Cir.2013). Where these three conditions are met, the Court may then exercise its discretion to correct the error, “but only if (4) the error seriously affects the fairness, integrity, or public reputation of judicial proceedings.” Id. 8) Whether defendants Dr. Kushner and Biseayne Milieu were denied a fair trial by the cumulative effect of the alleged trial errors. 9) Whether the individual defendant-appellants’ sentences are procedurally and substantively reasonable. This Court reviews de novo the district court’s interpretation of the guidelines and its application of guidelines to the facts. Findings of fact by the trial court at sentencing, however, are reviewed for only clear error. United States v. Medina, 485 F.3d 1291, 1297, 1303 (11th Cir. 2007) (loss amount); United States v. Ghertler, 605 F.3d 1256, 1267 (11th Cir.2010) (sophisticated means); United States v. De Varón, 175 F.3d 930, 937 (11th Cir.1999) (en bane) (role in the offense); United States v. Singh, 291 F.3d 756, 763 (11th Cir.2002) (obstruction of justice). The district court’s application of the vulnerable victim enhancement presents a mixed question of law and fact, which this Court reviews de novo. United States v. Arguedas, 86 F.3d 1054, 1057 (11th Cir.1996). “The district court’s determination of a victim’s ‘vulnerability’ is, however, essentially a factual finding to which [this court] give[s] due deference.” Id. And this Court reviews the final sentence imposed by the district court under an abusé of discretion standard. United States v. Pugh, 515 F.3d 1179 (11th Cir.2008). 10)Whether the district court correctly calculated Dr. Kushner’s restitution. This Court reviews de novo the legality of a restitution order and reviews any factual findings about the restitution amount for clear error. United States v. Bane, 720 F.3d 818, 827 (11th Cir.), cert. denied, — U.S. -, 134 S.Ct. 835, 187 L.Ed.2d 694 (2013). IY. SUFFICIENCY OF THE EVIDENCE A. Health Care Fraud Scheme Five defendants, Antonio Macli, Jorge Macli, Huarte, Biscayne Milieu, and Dr. Kushner, all challenge the sufficiency of the evidence underlying their convictions for conspiracy to commit health care fraud under 18 U.S.C. § 1347, in violation of 18 U.S.C. § 1349 (count 1), and substantive health care fraud in violation of 18 U.S.C. § 1347 (counts 2-8 and 11-12). Section 1347(a) provides a criminal penalty for anyone who: “knowingly and willfully executes, or attempts to execute, a scheme or artifice (1) to defraud any health care benefit program; or (2) to obtain, by means of false or fraudulent pretenses, representations, or promises, any of the money or property owned by, or under the custody or control of, any health care benefit program, in connection with the delivery of or payment for health care benefits, items or services.” 18 U.S.C. § 1347 (emphasis added). Section 1349 provides a criminal penalty for anyone who “attempts or conspires to commit any offense under this chapter,” which includes offenses under § 1347. 18 U.S.C. § 1349. Thus, § 1349 makes it unlawful to attempt or conspire to commit a § 1347 crime of health care fraud. To sustain the conspiracy conviction under 18 U.S.C. § 1349, the government must prove that (1) a conspiracy existed; (2) the defendant knew of it; and (3) the defendant knowingly and voluntarily joined it. United States v. Vernon, 723 F.3d 1234, 1273 (11th Cir.2013). Because the crime of conspiracy is “predominantly mental in composition,” the government may prove these elements by circumstantial evidence. Id.; United States v. Mateos, 623 F.3d 1350, 1362 (11th Cir.2010) (affirming Medicare fraud convictions based on circumstantial evidence of knowledge). The nature of conspiracy requires proof by such inferences and circumstantial evidence. See Vernon, 723 F.3d at 1273; Mateos, 623 F.3d at 1362. “[T]he government need not prove that the defendant knew all of the details or participated in every aspect of the conspiracy.” Vernon, 723 F.3d at 1273; see also Mateos, 623 F.3d at 1363. Instead, the government’s burden is only to prove that the defendant knew of “the essential nature of the conspiracy.” Vernon, 723 F.3d at 1273. A conspiracy conviction will be upheld “when the circumstances surrounding a person’s presence at the scene of conspiratorial activity are so obvious that knowledge of its character can fairly be attributed to him.” Id.; Mat-eos, 623 F.3d at 1362. “As for the voluntary joining element, the government can meet this burden ‘through proof of surrounding circumstances such as acts committed by the defendant which furthered the purpose of the conspiracy.’” Vernon, 723 F.3d at 1274 (citation omitted). Here, the jury was properly instructed as to all of the elements of the §§ 1347 and 1349 crimes. In particular, and in contrast to the purely individual focus of the appellants’ briefs, the jury was instructed that for these substantive crimes, where a defendant is a member of a conspiracy, he or she is criminally liable for his or her co-conspirator’s reasonably foreseeable crimes committed during the course of and in furtherance of the conspiracy. Pinkerton v. United States, 328 U.S. 640, 645-48, 66 S.Ct. 1180, 1183-84, 90 L.Ed. 1489 (1946); United States v. Silvestri, 409 F.3d 1311, 1335 (11th Cir.2005). As recounted in detail above and summarized here, the government clearly introduced sufficient evidence to uphold each conviction as to each of these five appellants. As to defendant Antonio Macli, ample evidence demonstrated his control of the Biscayne Milieu business. Multiple witnesses testified that Antonio Macli was ultimately in charge. Though he often delegated tasks which implemented the fraud scheme, this delegation was entirely consistent with his managerial control. Defendant Antonio Macli had access to the “money sheets” throughout the course of the conspiracy, and he directed the format of the false employee filing for “case management” services. After hearing seven weeks of trial evidence, the district court found at sentencing that Antonio Macli “had intimate knowledge of everything, including the amount that was going to be paid” by Medicare. As to defendant Jorge Mach, his day-to-day management of Biscayne Milieu played a key role in the conspiracy. He acted as the contact person for Medicare, hired recruiters to find and refer patients, approved of the recruiting of Haitian patients, and pioneered the recruitment of substance-addicted patients from out of state. As to defendant Huarte, her significant role was made clear by her active involvement in the Medicare billing process. She maintained the personnel records on the recruiters and implemented the controls regarding therapy notes. At sentencing, the district court found that defendant Huarte was not “similarly situated” to other defendants in the case who ultimately received lower sentences, additionally stating that Huarte’s actions “created problems for patients by not giving them the help they deserved, and [ ] ruinfing] the lives of a number of legitimate therapists.” As to defendant Dr. Kushner, his centrality to the scheme is easily stated. He referred and steered patients treated at local hospitals to Biscayne Milieu even though the patients were not eligible for PHP treatment. Through his dual positions at local hospitals and Biscayne Milieu, he was able to control patients going back and forth between Biscayne Milieu and the hospitals. Many of these same patients were repeatedly recycled through Biscayne Milieu after the PHP treatment failed to treat their underlying condition, most often active substance abuse. And as the district court found, the evidence showed Dr. Kushner did improper initial psychiatric evaluations, offered insufficient individualized treatment, and falsely certified that the Medicare rules had been followed. Given the evidence recounted above and earlier in this opinion, we readily conclude the government presented overwhelming evidence for a reasonable jury to convict these five appellants of the conspiracy to commit health care fraud and the substantive health care fraud counts. B. Kickbacks Five defendants, Antonio Macli, Jorge Macli, Huarte, Biscayne Milieu, and Alexander, challenge the sufficiency of the evidence in support of their convictions for conspiracy to receive and pay health care kickbacks in connection with a federal health care program as prohibited by 42 U.S.C. § 1320a — 7b(b)(l) and (2), in violation of 18 U.S.C. § 371 (count 15). Defendants Antonio Macli and Jorge Macli also challenge the sufficiency of the evidence to support their convictions as to counts 16-26, for the payment of specific kickbacks in violation of 42 U.S.C. § 1320a-7b(b)(2)(A). Defendant Alexander also challenges his conviction for the receipt of a $990 kickback (count 28) in violation of 42 U.S.C. § 1320a-7b(b)(l)(A). The Anti-Kickback statute, 42 U.S'.C. § 1320a-7b(b), underlies these charges. Subsection (b)(1) criminalizes the receipt, and subsection (b)(2) criminalizes the payment, of money “in return for referring an individual to a person for the furnishing ... of any item or service for which payment may be made in whole or in part under a Federal health care program.” 42 U.S.C. § 1320a-7b(b)(1) and (2); Vernon, 723 F.3d at 1251-52. Both defendants Antonio Macli and Jorge Macli hired recruiters and authorized the payment of kickbacks to the recruiters to induce them to locate and refer patients to Biscayne Milieu. Defendant Antonio Macli signed checks payable to recruiters. And the simple math of the kickback scheme is illustrated by the documented $990 payment to defendant Alex-' ander. The “money sheet” for a given time period showed that defendant Alexander was credited for 33 patient “days” in a two-week period. He was paid $990, which equals 33 patient days at $30 a day. The jury could reasonably infer a kickback scheme fully in operation. In addition, the evidence showed that defendant Dr. Kushner also referred and steered patients he treated at local hospitals to defendant Roberts, a recruiter, and some of the other recruiters, who then often fought over the doctor’s referrals. C. Money Laundering Defendants Antonio Macli, Jorge Macli, and Huarte challenge the sufficiency of the evidence to support their convictions for conspiracy to commit money laundering in violation of 18 U.S.C. § 1956(h). That section makes it a crime to conspire to commit money laundering in violation of 18 U.S.C. § 1956 or § 1957. Under § 1956(h), “only two elements of conspiracy need be proven: (1) an agreement between two or more persons to commit a money-laundering offense; and (2) knowing and voluntary participation in that agreement by the defendant.” United States v. Broughton, 689 F.3d 1260, 1280 (11th Cir.2012). The two objects of the money laundering conspiracy charged in count 30 are: (1) to conduct financial transactions involving the proceeds of specified unlawful activity knowing that the transactions were designed to “conceal or disguise” the nature, location, source, ownership, and control of the proceeds of the specified unlawful activity, in violation of 18 U.S.C. § 1956(a)(l)(B)(i) (“concealment money laundering”); and (2) to engage in monetary transactions involving “criminally derived property of a value greater than $10,000,” such property having been derived from specified unlawful activity, -in violation of 18 U.S.C. § 1957 (“ § 1957 money laundering”). The “specified unlawful activity” was alleged to be health care fraud in violation of 18 U.S.C. § 1347. The jury, by special verdict form, found defendants Antonio Macli, Jorge Macli, and Huarte guilty of both objects of the conspiracy. These three appellants argue their convictions cannot be sustained because they did not “conceal” their funds. This ignores that evidence showed the shuffling of money through various accounts that could be reasonably read as an attempt to conceal the proceeds of the fraud. Evidence also showed the use of sub-leasing agreements which, in effect, funneled fraud proceeds disguised as rent payments to Huarte. Appellants’ argument fails in any event. Though the jury found the defendants guilty of both objects of the conspiracy, the evidence need only be sufficient for any one of the charged objects to sustain a conviction. Medina, 485 F.3d at 1301. Concealment is an element of § 1956(a) money laundering crime, but not of § 1957 money laundering crime. United States v. Wetherald, 636 F.3d 1315, 1325 n. 2 (11th Cir.2011). Section 1957 requires that the property have a value greater than $10,000, but it does not require that the defendant know of a design to conceal aspects of the transaction or that anyone have such a design. “Due to the omission of a ‘design to conceal’ element, section 1957 prohibits a wider range of activity than money ‘laundering,’ as traditionally understood.” Id. (internal citation omitted). The appellants would have to prevail on a sufficiency challenge to the underlying § 1957 counts in order to gain any traction here. This they cannot do. Ample evidence demonstrated the existence of monetary transactions in excess of $10,000 related to the above-discussed health care fraud in violation of 18 U.S.C. § 1347. For example, at trial an FBI forensic accountant explained the movement of funds through accounts that took in money fraudulently obtained by Medicare billing and for which the defendants Antonio Macli, Jorge Macli, or Huarte were signatories. Viewing the evidence in the light most favorable to the verdict, sufficient evidence was presented to convict defendants Antonio Macli, Jorge Macli, and Huarte on the money laundering conspiracy and substantive money laundering counts. V. MULTIPLICITOUS COUNTS IN INDICTMENT Defendant Huarte argues, for the first time on appeal, that her two conspiracy convictions, in count 1 and count 15, are multiplicitous. Huarte contends that the kickback conspiracy count (count 15)'is a lesser-included offense of the health care fraud conspiracy count (count 1) and thus violates the Double Jeopardy Clause. Huarte’s argument fails. A defendant must object before trial to defects in the indictment, and the failure to do so waives appellate review. Fed.R.Crim.P. 12(b)(3)(B) and (e). See United States v. Pacchioli, 718 F.3d 1294, 1307-08 (11th Cir.), cert. denied, — U.S.-, 134 S.Ct. 804, 187 L.Ed.2d 597 (2013) (refusing to consider same argument because appellant did not raise it before trial). Thus, defendant Huarte waived this argument as a challenge to the indictment by failing to make it before trial. Of course, defendant Huarte still challenges on appeal her sentences on counts 1 and 15. To the extent this multiplicity argument could be construed as a challenge to the sentences as being the result of multiplicitous convictions, see Pacchioli, 718 F.3d at 1308, we briefly address this argument and find it wholly wanting. As to her multiplicity claims, Huarte has not demonstrated any error, much less plain error. Huarte’s convictions on counts 1 and 15 are not multiplici-tous because they involve two conspiracies with different objects and thus different elements. More specifically, count 1, a conspiracy under 18 U.S.C. § 1349 to violate 18 U.S.C. § 1347 and § 2, contains a different set of elements from count 15, a conspiracy under 18 U.S.C. § 371 to violate 42 U.S.C. § 1320a-7b(b)(l) and (2). As charged in count 1 in this case, the § 1349 conspiracy to commit health care fraud under § 1347 required that fraud be the object of the conspiracy. The main unlawful purpose of the conspiracy charged in count 1 was the false and fraudulent claims and representations made to Medicare. As to count 15, however, § 371 prohibits two or more persons from conspiring to commit any offense against the United States. 18 U.S.C. § 371. Further, § 371 requires proof of an overt act, while § 1349 does not. Moreover, the unlawful purpose of the conspiracy in count 15 was the payment and receipt of kickbacks for patient referrals. Unlike in count 1, the conduct (and even the submitted claims to Medicare) did not need to be fraudulent. Even if a patient was eligible for PHP treatment and actually received covered medical treatment, it was still illegal for the co-conspirator owners and operators of Biseayne Milieu, including defendant Huarte, to conspire to pay recruiters for patient referrals and for those recruiters to receive payments. See United States v. Njoku, 737 F.3d 55, 68 (5th Cir.2013) (holding that a conviction for § 1349 conspiracy to commit a conviction for § 1347 health care fraud and § 371 conspiracy to pay health care kickbacks in violation of 42 U.S.C 1320a-7b(b) are not multiplicitous convictions), cert. denied, — U.S. -, 134 S.Ct. 2319, 189 L.Ed.2d 196 (2014). There is no multiplicity error in this case. Alternatively, even if defendant Haurte were somehow correct, this would not impair her substantial rights. Huarte’s 22-month sentences as to counts 1 and 15 are to be served concurrently. “Thus, any claimed multiplicity in the indictment would have been harmless error anyway.” Pacchioli, 7Í8 F.3d at 1308 (holding any multiplicity error in the indictment was “obviously harmless because the arguably multiplicitous counts resulted in concurrent sentences”). VI. JUROR REMOVAL/ATTORNEY MISCONDUCT Four defendants, Alexander, Roberts, Dr. Kushner, and Jorge Macli, argue that the district court abused its discretion by failing to remove a juror and denying their motion for mistrial after an episode oc-during during defense counsel for defendant Alexander’s cross-examination of therapist Barbara Morales. During his cross-examination of therapist Barbara Morales about her practice of copying and pasting group therapy notes, defendant Alexander’s attorney discussed one effect of such copying and pasting, which was that pronouns were often incorrect with respect to the sex of the patient subject of the therapy note. In discussing this phenomenon, which illustrated the copying and pasting of notes, defendant Alexander’s attorney made the following remark, highlighted in the exchange below: Q. Using, let’s say, Jacqueline Moran and John Jackson, if they were two patients and you took John Jackson’s report and you put it on Jacqueline Moran, all of a sudden, she would become a he because you cut and pasted sections? A. I agree with you. Q. If you did it in reverse and you took a section of Jacqueline Moran’s evaluation and put it on John Jackson, he would then become a she? A. Yes. Q. Which he probably wouldn’t mind anyioay. A. Copy and paste. The government immediately objected to the attorney’s remark, and the district court sustained the objection. Defendant Alexander’s attorney immediately apologized to the district court, witness, and jury. At the next recess, the district court upbraided the attorney. During the same recess, the district court received a note from Juror 13 stating the following: “I want a written transcript for today’s cross-examination by the lawyer who made the comment about John Jackson being gay, that he/she comment at around 2:40 p.m. I intend to take it to Gay Services (GLADD).” When the jury returned, the district court advised the jury that it had “sternly admonished” defendant Alexander’s attorney outside of the jury’s presence, and that when the trial was over, anyone could get a copy of the transcript and take whatever action he or she felt was appropriate. The district court then asked the jury if it could be fair as to each defendant and make its decision only on the evidence, stating the following: But there are nine defendants on trial and I want to make sure and we all want to make sure that the fact that something out of place occúrred, and hopefully it will be isolated and nothing of its kind will infect the rest of this trial, we all want to make sure that your decision as to each of the defendant’s cases is made on the merits of the case and not on whether an attorney did something that they shouldn’t have done. So I need some assurances from all of you. I hope all of you share the concern that that kind of comment shouldn’t, be made, but I also need assurances from you, if you can give them to me, that you will be able to set that aside and to make your decision only on the evidence and the law as I instruct you; that you will consider each individual defendant’s case and decide whether or not the Government has proven the case or not proven the case and not let this isolated incident affect you. I am not ordering you to do that, but I heed to find out now if I can do that going forward. So can you all agree that you can do that? Is there anybody that has any concerns about not being able to do that? Raise your hand now. Okay. All right. So we’re going to go forward. No juror then indicated that he or she would not be able to proceed according to the district court’s instruction. Defendant Alexander’s attorney again apologized in the presence of the jury. Defendant Dr. Kushner then moved for a mistrial on the basis of the preceding events. The district court denied the motion for mistrial. The following day, the defendants moved to remove Juror 13. The district court denied the motion to discharge the juror. The district court questioned Juror 13 and also questioned each of the other jurors individually and outside the presence of the full jury. Each juror, including Juror 13, unequivocally stated that defendant Alexander’s attorney’s comment had no effect on his or her ability to weigh the evidence and to be fair to all parties. Just cause exists to discharge a juror where the district court finds evidence that-the juror cannot decide the issues fairly. Register, 182 F.3d at 840. The district court has substantial discretion in ferreting out and determining juror misconduct or bias. See id. And that discretion will not be disturbed absent a showing of bias or prejudice to the defendant. United States v. Fajardo, 787 F.2d 1523, 1525 (11th Cir.1986). Just cause cannot be shown on this record. Juror 13 assured the district court that he was able to be fair and decide the case based on the evidence, explaining that when he sent the note, “it wasn’t so much myself that was offended by it or felt uncomfortable. It was some of the other jurors.” Asked by the district court whether he could look at each of the defendants and at the prosecutors and tell them that the incident was “not even going to be any part of my thought process or discussion,” Juror 13 replied: “Exactly. That’s exactly how I feel. It won’t be part of my emotions or discussions and it won’t come up again.” Juror 13 was properly forthright in raising a concern about the comment and in answering the district court’s questions. The district court was thorough in questioning the jury as a group and each juror individually. The refusal to remove Juror 13 was not an abuse of discretion. Nor was the district court’s denial of the motion for a mistrial. The district court made a determination well within its discretion that bias had not affected the jury such that a mistrial, an extreme remedy, was warranted. VII. ADMISSION OF LAY TESTIMONY Defendants Alalu, Huarte, Dr. Kushner, and Biscayne Milieu argue that the district court abused its discretion by admitting the lay opinion testimony of various witnesses who testified as to the eligibility of patients to receive treatment as well as, in the view of appellants’, these patients’ medical diagnoses. Lay opinion testimony must be: “(a) rationally based on the witness’s perception; (b) helpful to clearly understanding the witness’s testimony or to determining a fact in issue; and (c) not based on scientific, technical, or other specialized knowledge within the scope of Rule 702.” Fed.R.Evid. 701. The determination of whether testimony is properly admitted as lay opinion is based upon the nature of the testimony, not whether the witness could be qualified as an expert. United States v. LeCroy, 441 F.3d 914, 927 (11th Cir.2006). And “Rule 701 does not prohibit lay witnesses from testifying based on particularized knowledge gained from their own personal experiences.” Hill, 643 F.3d at 841. The record shows that the testimony here in question — principally from social workers and therapists at Biscayne Milieu — was based on personal knowledge and reflected the experience of treatment providers with the treatment process, and its shortcomings, at Biscayne Milieu. These witnesses were not standing in for experts. We see no abuse of discretion in the district court’s decision to allow such evidence as lay opinion. Moreover, the defendants at trial did not clearly object to the bulk of the testimony they now seek to challenge on appeal. Defendants Antonio Macli, Jorge Macli, and Huarte did file a pre-trial motion to exclude opinion testimony from witnesses not licensed to render medical diagnoses. Following a hearing, the district court deferred ruling on the motion until trial had commenced. But when most of the evidence then was admitted during trial, the defendants did not point out or renew their motion to exclude. While there were a few objections to certain questions during this lay opinion testimony, most of this lay opinion testimony came in without objection at trial. After ruling on evidentiary challenges as they arose during trial, the district court ultimately denied the motion in limine at moot. To the extent the defendants did not object during trial as the testimony came in, they cannot now show that it was plain error, an even more exacting standard, to allow such lay opinion testimony. VIII. REFERENCE TO INVOCATION OF RIGHT TO COUNSEL Defendant Jorge Macli challenges the district court’s denial of his motion for mistrial, arguing that the government intentionally elicited testimony about his invocation of his right to counsel. On direct examination by the government, Health and Human Services Special Agent John Mejia testified that he interviewed Jorge Macli after his arrest. He testified that Jorge Macli waived his rights and agreed to be interviewed without his attorney present. The prosecutor asked: “And at any point did Mr. Macli say he wanted his lawyer to be present?” Agent Mejia answered: “Not initially.” Jorge Macli objected, and the district court struck the testimony. Defendant Jorge Macli then moved for a mistrial on the basis that the government had elicited an impermissible comment on his right to silence. The prosecutor apologized, stating that “the question was meant to be did he invoke his right to counsel at that time?” The district court denied the mistrial motion, but offered to give a “more strongly worded curative instruction.” Jorge Macli denied this offer, along with the district court’s offer to poll the jury about the effect of the remark, stating he did not want to “reemphasize” the testimony. The district court stated it would take the mistrial motion “under advisement” until it was able to determine “whether the evidence [was] overwhelming or not.” The government made no further reference to it. “A single, inappropriate reference to a defendant’s post-arrest silence that is not mentioned again is too brief to constitute a Fifth Amendment violation.” Reeves, 742 F.3d at 505. And, as the district court later found at the conclusion of the government’s case, because the evidence of Jorge Macli’s guilt was “overwhelming,” any unintentional error the government made by eliciting that he had invoked his right to counsel at a different time was harmless. IX. PROSECUTOR COMMENTS AT CLOSING ARGUMENT Defendants Alalu, Dr. Kushner, and Jorge Macli argue that the district court abused its discretion by denying motions for mistrial based on remarks made by the prosecutor during rebuttal closing argument. Appellants highlight two separate incidents. After noting the defense attorneys’ various attempts, in closing argument, to plead for sympathy for the circumstances of the various defendants, the prosecutor argued: We are all human beings and it is perfectly understandable to feel badly for the positions that these defendants have put themselves in, but your job is to evaluate their guilt based on the law and the facts. And recognize this: Over the course of the last six-and-a-half weeks, I think you have gotten to know all of us very well, and I think that you would agree with me that all of the defense attorneys are very — are very talented, very diligent and very committed to their client’s cause. Ask yourself this: If these attorneys are trying to subtlely tap into your feelings of sympathy, what does that say about what they know of what would happen— Jorge Macli’s attorney immediately objected, arguing this was not about sympathy but rather the government’s attempt to use defense counsel’s sympathy plea to show defense counsel’s awareness of their clients’ guilt. The district court sustained the objection and struck the comment, telling the jury to disregard the prosecutor’s last statement. After the government’s closing, the defendants moved for a mistrial, arguing the comments regarding the sympathy pleas had undermined the defense lawyers’ effectiveness before the jury. The district court denied the motion but gave a curative instruction to the jury, stating in part: So whether [the prosecutor] was misunderstood or misspoke, what he said concerning what the lawyers may or may not think is just not proper and it shouldn’t be considered by you. All these lawyers are very ethical and you have seen them, as [the prosecutor] even pointed out himself, that they are talented, they care about their clients, they care about the case and they care about doing the right thing. I think that is everybody’s goal here and it has been throughout the last couple of months. So please do not consider that when you go to consider your verdict tomorrow. Defendants Dr. Kushner and Biscayne Milieu argue that another remark, which also gave rise to a denied motion for mistrial, resulted in an abuse of discretion by the district court. The prosecutor discussed the case of a repeat Biscayne Milieu patient who ultimately died. The prosecutor stated: The reason why Biscayne Milieu stopped billing for Richard Adderley is that he died. And he died — we don’t know if treatment — if the better form of treatment would have helped, but we know that Biscayne Milieu didn’t care. Richard Adderley was someone who was set up for failure at Biscayne Milieu like so many other
