JON O. NEWMAN, Circuit Judge: This is an appeal by six defendants, including a former United States Congressman, from convictions arising out of the affairs of the Wedtech Corporation, a manufacturing company located in New York City that received contracts from the Defense Department. The defendants are former Congressman Mario Biaggi; his son, Richard Biaggi; the Congressman’s former law partner, Bernard Ehrlich; the former Bronx Borough President, Stanley Simon; the former chief executive officer of Wedtech, John Mariotta; and the former New York regional administrator of the Small Business Administration, Peter Neg-lia. The six defendants appeal from judgments of conviction entered November 18, 1988, in the Southern District of New York (Constance Baker Motley, Judge) after a five-month jury trial. The appeal presents a host of issues. It also requires some consideration of the distinction between bribes and extortion payments, on the one hand, and political contributions and legal fees, on the other hand. The distinction is clear in theory, but this case demonstrates how blurred the line can become in practice when a company that requires political assistance and legal services in dealing with governmental bureaucracies makes payments to office holders and lawyers associated with them. Though the distinction is implicated in this case, we are satisfied that the risk of mis-charaeterizing lawful political contributions and legal fees as bribes and extortion payments did not reach the point where rights of the defendants were denied. Other considerations, however, lead us to reverse convictions of some defendants on some counts. We affirm the convictions of all defendants on at least two counts. BACKGROUND To promote understanding of the many issues in this complex case we set forth first the undisputed facts of Wedtech’s history and then the Government and the defense contentions concerning the different activities that form the basis for the criminal charges. Undisputed Facts. Wedtech began its existence as Welbilt Electronic Tool & Die Corporation (“Welbilt”), a small sheet metal fabricating company located in the South Bronx. Welbilt changed its name to Wed-tech in 1983 when it made a public offering of its stock. For convenience, we will refer to the company at all times as “Wedtech.” Defendant John Mariotta founded the company and remained chairman until company officials ousted him in 1986. In 1975 Wed-tech was accepted into the Small Business Administration’s “Section 8(a)”. program, under which minority-owned businesses are eligible for government contracts without competitive bidding. See 15 U.S.C. ■ § 637(a) (1988). Mariotta is of Puerto Ri-can descent. In 1978 defendant Mario Biaggi, then a Congressman from the Bronx, met Mariot-ta and Fred Neuberger, a co-owner of Wed-tech. In addition to serving in Congress, Biaggi was at that time a partner in a small law firm, known as Biaggi & Ehrlich. His law partner was defendant Bernard Ehrlich. Wedtech retained Biaggi & Ehrlich, initially at an annual retainer of $20,-000. The retainer was subsequently increased in stages to $150,000. Biaggi withdrew as a member of the law firm in 1979, after the House of Representatives adopted Rule XLVII, which limited outside income of members of the House to 30 percent of their salaries. The law firm bought his partnership interest for $320,000 to be paid over a ten-year period. Biaggi remained in an “of counsel” relationship to the firm. Biaggi’s son, defendant Richard Biaggi, became a partner in the firm in 1983. Starting in 1978, Biaggi (all references are to the father, unless otherwise indicated) contacted various governmental officials on behalf of Wedtech, urging awards of contracts from the Defense Department through the SBA’s section 8(a) program and loans from the Economic Development Administration. In addition to Biaggi, Wedtech also benefitted from the services of attorney E. Robert Wallach, former White House assistant Lyn Nofziger, and other Washington lobbyists. Wallach frequently contacted then White House Chief of Staff Edwin Meese on Wedtech’s behalf. Among the benefits achieved for Wed-tech by its lobbyists and lawyers were the awards of a $27 million contract in 1982 to make small engines for the Army and a $24 million contract in 1984 to make pontoons (raft-like structures carried on ships to aid in unloading) for the Navy. Despite these contract awards, Wedtech experienced serious financial difficulties and ultimately filed for bankruptcy at the end of 1986. Contentions Concerning Criminality. The Government’s evidence against the defendants came primarily from four Wed-tech officials, Fred Neuberger, Mario Moreno, Lawrence Shorten, and Anthony Guar-iglia. These four cooperating witnesses had been charged with a series of federal and state violations arising out of their activities at Wedtech and had pled guilty pursuant to plea agreements. All four testified under grants of use immunity. Their testimony concerned six basic matters: 1. The Five Percent Stock Interest. When Wedtech went public, the company issued two and one-half percent of its stock to Ehrlich and an equal percent to Richard Biaggi. The Government contended that Richard was given his share as a nominee for his father, that the total five percent stock interest was paid as a bribe to influence Congressman Biaggi to use the powers of his office to secure government contracts for Wedtech, and that the payment was made in response to an extortionate demand by the Congressman, aided by Ehrlich. A restriction precluded sale of the shares for two years, a circumstance that made it difficult to ascertain their value when issued. The law firm’s accountant placed the value, when issued, at $35,000 for each recipient. After the restriction was lifted, Ehrlich and Richard Biaggi sold about one-third of their shares, each realizing more than $600,000. The defendants contended that the five percent stock interest was transferred to the partners of the law firm, Ehrlich and Richard Biaggi, in fulfillment of a previous promise to reward the firm for its loyalty to Wedtech in the early days when the firm billed modestly for legal services, declined to insist on prompt payment, and did not bill at all for some services. Defendants also contended that Richard Biaggi was issued the stock for himself as a partner in the law firm, and not as a nominee for his father. 2. The $50,000 Loop Drive Payment. After Wedtech obtained the pontoon contract from the Navy, it needed a waterside property at which to test the vessels and identified a site known as One Loop Drive, located in the Bronx. The property was owned by New York City. To secure the City’s willingness to lease the property, Ehrlich sought the assistance of defendant Stanley Simon, who was then the Bronx Borough President and a member of the Board of Estimate, which approved City leases. Simon arranged for Wedtech officials to meet with Susan Frank, the City’s Commissioner of Ports and Terminals. Over the course of a few days in June 1984, a three-year lease was negotiated whereby the City agreed to rent the Loop Drive property to Wedtech for $50,000 a year, well below the annual rent of $125,000 the City had initially requested. Ehrlich negotiated the lease terms on behalf of Wed-tech. Ehrlich and his firm also negotiated with a corporation that occupied the building at One Loop Drive to assure Wedtech’s use of the site’s parking lot in connection with waterside activities required to fulfill the pontoon contract. The lease required approval of the Board of Estimate. Wedtech needed prompt approval in order to satisfy the Navy that it had the waterside site needed to perform the contract. To secure approval at the Board’s June 13 meeting required unanimous consent, since the matter had arisen too quickly to be placed on the agenda for that meeting. Two Board members objected, and, consequently, the item was deferred until July. Biaggi called Simon and demanded his assistance in having the lease approved at a subsequent meeting.' According to Moreno, Ehrlich reported that Biaggi had “punished” Simon, warning him “that his next election depended bn Mario Biaggi’s support and that he had to start moving really quick.” The Board approved the lease at its July 12 meeting. Ehrlich informed Moreno that the law firm would bill Wedtech $50,000 for work performed in connection with the Loop Drive property. At that time the firm’s annual retainer was $150,000. Ehrlich said that the transaction required considerable extra work. He referred both to strictly lawyering activities and to political efforts the firm undertook to secure Board of Estimate approval. The firm billed Wedtech $50,000 for “Ports and terminal matter. Services rendered June 1984,” and the bill was paid on July 13. Thereafter, Moreno paid a young associate at the firm, Carlos Cuevas, Jr., $5,000 as a bonus for his work on the Loop Drive transaction. The Government contended that the $50,-000 payment to the law firm was a bribe to Biaggi to induce him to use his official position to secure City and Board of Estimate approvals for the Loop Drive lease and that the payment was made in response to extortionate demands by Biaggi, aided and abetted by Ehrlich. The defendants contended that the $50,-000 was a fee for legal services rendered in connection with leasing the Loop Drive property. 3. Benefits to Simon. The Government contended that Stanley Simon also made an extortionate demand upon Wed-tech for $50,000, which the Government alleged was in connection with the Loop Drive lease. Neuberger testified that in June 1984 he attended a benefit for the Riverdale (New York) Hebrew Home for the Aged held at the Yonkers racetrack. At that function, according to Neuberger, Simon said to him that “he [Simon] is running a re-election campaign that is a very hard fought campaign and he needs help.” When Neuberger asked, “[W]hat kind of help do you expect?”, Simon replied $75,000- or $100,000. Neuberger thought these figures were ridiculous and observed that it was illegal for a corporation “to make a contribution to a campaign.” Simon then said, “[W]ell, do it in the form of donations to synagogues, churches and some other expenses.” Neuberger said the best he could do was $50,000 and “we settled for that.” Neuberger also testified that at the same function, he asked Susan Frank how things looked for the Loop Drive lease and was told that “you are in good shape.” At that point, Neuberger testified, Simon pulled him aside and cautioned him not to talk with Frank. Neuberger testified that the following Monday he gave instructions to a Wedtech employee, Ceil Lewis, to release a total of $50,000 for purposes that Simon would later indicate to her and to disburse the funds from a Wedtech account known as the FHJ account. The Government contended that the FHJ account was used to pay most of the $50,000 that Neuberger had promised Simon. According to the Government, the major expenditures were $20,000 in charitable contributions to two synagogues, $10,000 as a political contribution to “Friends of Simon,” and $10,000 in cash. Lewis testified that she gave the cash in a sealed envelope to Simon’s assistant, Ralph Lawrence; he testified that he received an envelope from Lewis and gave it to Simon, unopened. Simon acknowledged that Wedtech benefited his reelection campaign but disputed the timing, purpose, and completion of the $50,000 of payments. He presented evidence from those handling arrangements for the Riverdale Hebrew Home to show (a) that the June 1984 fund-raising event at the Yonkers Raceway was arranged by the Men’s Club of the Home and that the guest list, which included about 80 people, did not include the names of Stanley Simon or Fred Neuberger, and (b) that the Bronx Division of the Hebrew Home ran a fund-raising event at the Yonkers Raceway in November 1984 and that the guest list for this event showed Stanley Simon, Fred Neuber-ger, and Susan Frank in attendance. Simon contended that the discussion concerning a political contribution occurred in January 1985 at his home on an occasion when he was receiving visitors mourning the death of his father. At that time, he testified, Neuberger volunteered that “people at the company” were going to contribute $50,000 to his 1985 reelection campaign for borough president. Simon testified that Neuberger later contributed $10,000 and Mariotta $5,000. He denied receiving other political contributions from Wedtech officials and denied receiving a cash payment delivered by Lawrence or anyone else. Thus, Simon’s version was that the June 1984 race-track meeting between him and Neuberger never occurred, that such a meeting did occur at a similar fund-raising event in November 1984, months after the Board of Estimate had approved the Loop Drive lease, that the political contribution was not discussed until January 1985, that only $15,000 of contributions were received, and that any payments received were legitimate political contributions. In addition to the $50,000 of payments allegedly made in response to an extortionate demand in connection with the Loop Drive lease, the Government contended that Simon received three other unlawful benefits, one of which was paid by Wed-tech. Moreno testified that in 1981 Ehrlich introduced him to Simon, whom Ehrlich described as an important person to be “cultivated.” Later Ehrlich told Moreno that Simon wanted Wedtech to hire Simon’s brother-in-law, Henry Bittman. Wedtech complied, hiring Bittman as a payroll clerk at $20,000 a year and subsequently raising his salary to $35,000. Wedtech employees testified that Bittman’s work was unsatisfactory but that he was kept on the payroll in fulfillment of a promise to Simon. Simon did not dispute that Wedtech hired Bittman and gave him raises but denied that he had ever asked anyone at Wedtech to do so. The two other alleged benefits were not paid by Wedtech. First, the Government contended that Simon hired Ralph Lawrence as his assistant when he was the Bronx Borough President and, when Lawrence’s salary rose to $36,000, demanded that Lawrence kick back to him one half of all subsequent salary increases. Lawrence testified that, as his salary rose to $52,000, he shared half of his salary increases with Simon, providing the kickbacks in cash and purchases of goods and services for Simon’s benefit, a significant portion of which was meals. The value of the kickbacks was approximately $14,000 over three and one-half years. Simon acknowledged hiring Lawrence but denied demanding or receiving any portion of his salary. He also denied receiving cash from Lawrence. He acknowledged occasions when Lawrence paid a meal check for him, but maintained that the two ate together hundreds of times a year (as Lawrence had testified) and that sometimes Simon paid and sometimes Lawrence paid. Simon accused Lawrence of lying about the extortion arrangement, contending that Lawrence had made up the claim during a late-night questioning by the Bronx District Attorney’s office. Lawrence conceded that he was frightened during the questioning and made his accusations around 2 a.m. The second non-Wedtech illegality charged to Simon concerned Sabino Fogli-ano, a Bronx contractor. The Government contended that Simon arranged introductions for Fogliano with various New York City officials and that in return Fogliano provided benefits to Simon. The only benefit alleged in the charges against Simon was $9,000 worth of marble and tile work done by Fogliano at Simon’s home. Fogli-ano testified that he did the work at Simon’s request and did not send a bill because he knew he would not be paid. Simon acknowledged that Fogliano had supplied labor and materials worth $9,000 for work at his home, but he testified that the tile work was part of an overall home renovation job estimated to cost more than $22,000, that the job was never finished, and that he did not pay Fogliano both because he was not billed and because the work was not completed. Simon also contended that Fogliano did not send a bill once he learned that Simon was under federal investigation because Fogliano wanted to avoid any dealings that might direct federal investigators in his direction. Fog-liano testified against Simon under a grant of use immunity from the federal government, and admitted on cross-examination that he had evaded federal income taxes on $800,000 of income. After trial, however, Fogliano pled guilty to New York state charges of evading taxes on $8,500,000. Simon unsuccessfully sought a new trial on the ground that Fogliano had lied to minimize the extent of his tax evasions, thereby precluding an effective attack on his credibility and his motive for accusing Simon. 4. The Section 8(a) Fraud. The Government contended that Wedtech’s application for admission to the section 8(a) program and its subsequent retention in the program by the SBA were fraudulent. A company qualifies for the section 8(a) program if it is at least 51 percent owned by “one or more socially and economically disadvantaged individuals,” 15 U.S.C. § 637(a)(4)(A)(i)(I), a phrase that includes members of groups subjected to racial or ethnic prejudice, id. § 637(a)(5); see 13 C.F.R. § 124.105(b) (1990) (Hispanic Americans). Mariotta is of Puerto Rican descent. When Neuberger became Mariotta’s partner, they created false documents to make it appear that Mariotta owned 66% percent of Wedtech’s stock, whereas each in fact owned 50 percent. After Wedtech went public, the dilution of Mariotta’s interest prompted Mariotta and other Wedtech officials to devise fraudulent arrangements to make it appear that Mariotta retained a.n ownership interest above 50 percent. The device was a series of “stock purchase agreements” whereby insiders who had received stock purported to assign their interests to Mariotta, who was obligated to pay for the shares over a ten-year period, with no payments due for the first two years; upon Mariotta’s failure to pay, the shares would revert to the insiders. Mariotta verbally agreed with the insiders that he would not make the payments, thereby assuring that the insiders would retain their interests. The defendants contended that Mariotta owned two-thirds of Wedtech’s stock when the first section 8(a) application was made and that the stock purchase agreements whereby he retained record ownership of a majority of Wedtech shares, after the public offering, were bona fide. 5. The Slush Fund. The Government contended that Mariotta and Neuberger established a bank account, known as “FHJ Associates,” which they used to divert’ to themselves cash that belonged to Wedtech. The account was funded with money earned on goods manufactured by Wedtech but billed on FHJ invoices. Subsequently, other Wedtech officials, including Moreno, Shorten, and Guariglia, participated in the FHJ account. By the time he left Wedtech, Mariotta had received more than $1 million in cash from the FHJ account. The Government made no claim that any defendant other than Mariotta benefitted from the FHJ account. Mariotta contended that funds he received from the FHJ account were repayments of loans that he had made to Neu-berger. 6. The Neglia Bribe. The Government contended that Wedtech officials obtained the cooperation of defendant Peter Neglia, the New York regional administrator of the SBA and later the chief of staff to the SBA Administrator in Washington, by bribing him with a promise of future employment. According to Moreno’s testimony, Ehrlich and Moreno promised Neglia that after he left government employment he would have a job at the law firm of Biaggi & Ehrlich at a salary of $100,000 and that half of his salary would be paid by Wed-tech. The Government contended that this promise was made for Neglia’s past help and in the expectation of his future assistance. Neglia had assisted Wedtech in remaining in the section 8(a) program after the public offering had diminished Mariotta’s holding below the 50 percent mark, rendering Wedtech ineligible for continued participation. The Government contended that Neglia was aware of the sham nature of the Mariotta stock purchase agreements and of Wedtech’s ineligibility for continued participation in the section 8(a) program. After the promise of future employment, Neglia alerted Wedtech to efforts brewing in the SBA and in Congress to decertify Wedtech and acted to keep Wedtech in the section 8(a) program. Neglia denied acting improperly on Wed-tech’s behalf and denied being promised any employment with Biaggi & Ehrlich. He acknowledged that after he left the SBA in early 1986, he opened his own law office and did legal work for Biaggi & Ehrlich in an “of counsel” capacity to the firm. In 1986 the firm paid him $42,000. These six episodes resulted in convictions of the appellants on the following charges: 1. The Five Percent Stock Interest: extortion, 18 U.S.C. § 1951 (1988): Biag-gi, Ehrlich bribery, 18 U.S.C. § 201(b) (1988): Biag-gi, Ehrlich, Mariotta, Richard Biaggi gratuity, 18 U.S.C. § 201(c) (1988): Biag-gi, Ehrlich, Mariotta, Richard Biaggi mail fraud, 18 U.S.C. § 1341 (1988): Bi- aggi, Ehrlich, Richard Biaggi false financial disclosure, 18 U.S.C. § 1001 (1988): Biaggi false tax return, 26 U.S.C. § 7206(1) (1988): Biaggi, Richard Biaggi 2.The $50,000 Loop Drive Payment: extortion: Biaggi, Ehrlich bribery: Biaggi, Ehrlich, Mariotta mail fraud: Biaggi, Ehrlich 3.Benefits to Simon: $50,000 payment: extortion: Simon grand jury perjury, 18 U.S.C. § 1623 (1988): Simon tax evasion, 26 U.S.C. § 7201 (1988): Simon Job for Bittman: extortion: Simon grand jury perjury: Simon Lawrence kickbacks: extortion: Simon tax evasion: Simon grand jury perjury: Simon Fogliano tile work: tax evasion: Simon grand jury perjury: Simon 4. The Section 8(a) Fraud: mail fraud: Biaggi, Ehrlich, Mariotta 5. The Slush Fund: tax evasion: Mariotta 6. The Neglia Bribe: bribery: Ehrlich, Neglia gratuity: Ehrlich, Neglia obstructing justice, 18 U.S.C. § 1503 (1988): Neglia Most of these substantive offenses were also charged as racketeering acts for purposes of RICO substantive and conspiracy offenses, 18 U.S.C. § 1962(c), (d) (1988). The jury found that Biaggi, Ehrlich, and Mariotta committed two or more RICO predicate acts and convicted these three defendants of RICO substantive and conspiracy offenses. In addition, Biaggi was convicted of grand jury perjury for falsely denying that he contacted the Government on behalf of Wedtech. The following aggregate sentences were imposed: DISCUSSION I. Joinder Misjoinder claims are advanced by several defendants. The major challenge is brought by Simon, who contends that he was entitled to a severance of two counts that charged criminal activity unrelated to Wedtech. Count 21 charged Simon with extorting from Ralph Lawrence, his assistant in the Bronx Borough President’s office, one half of Lawrence’s salary increases; Count 23 charged tax evasion for the year 1985, based on failure to report the $50,000 in benefits from Wedtech, the salary kickbacks from Lawrence, and the $9,000 of tilework from Sabino Fogliano. Simon contends that since he was tried with other co-defendants, the governing standards are those of Rule 8(b) (joinder of defendants) of the Federal Rules of Criminal Procedure, rather than Rule 8(a) (join-der of offenses), and that joinder of Counts 21 and 23 is not permissible under Rule 8(b). Judge Motley initially denied Simon’s motion for severance, ruling that Rule 8(a) governed and that these counts were of “the same or similar character,” Fed.R. Crim.P. 8(a), as other extortion counts in the indictment. United States v. Biaggi, 672 F.Supp. 112, 124 (S.D.N.Y.1987). Simon renewed his motion after this Court’s decision in United States v. Turoff, 853 F.2d 1037, 1043 (2d Cir.1988), which appeared to state that claims for severance of counts in a multi-defendant case are to be governed by the standards of Rule 8(b). In a thoughtful opinion, drawing upon the equally thoughtful opinion of Judge Sand in United States v. Clemente, 494 F.Supp. 1310 (S.D.N.Y.1980), aff'd on other grounds sub nom. Fiumara v. United States, 727 F.2d 209 (2d Cir.), cert. denied, 466 U.S. 951, 104 S.Ct. 2154, 80 L.Ed.2d 540 (1984), Judge Motley ruled that Turoff should be understood to apply Rule 8(b) standards to the claim of a defendant in a multi-defendant trial only when he seeks severance of counts in which he and at least one of his co-defendants are charged, and that Rule 8(a) standards apply to a defendant in a multi-defendant trial who seeks severance of counts in which he is the only defendant charged. United States v. Biaggi, 705 F.Supp. 852 (S.D.N.Y.1988). However, Judge Motley also ruled that Counts 21 and 23 were properly joined even under the standards of Rule 8(b). Id. at 855-56, 862-64. Without resolving the issue of whether Turoff should be limited in the manner suggested by Judges Motley and Sand, we agree with the District Court that joinder of Counts 21 and 23 was proper even under Rule 8(b). Though the Lawrence extortion (Count 21) did not involve the same victim as Simon’s extortion of Wedtech, the Lawrence extortion was within “the same series of acts or transactions,” Fed.R.Crim.P. 8(b), as the extortions charged to Simon’s co-defendants. Simon used Lawrence as the means of obtaining many of the benefits he derived from Wed-tech, notably the $10,000 cash payment. His demand to receive benefits from Lawrence was inextricably related to his extortion of Wedtech. Proof of one scheme was helpful to a full understanding of the other. See United States v. Turoff, 853 F.2d at 1044. Simon’s tax evasion for 1985 (Count 23) was also properly joined under Rule 8(b). Turoff recognized the propriety of joining tax counts to non-tax counts in mul-ti-defendant cases where the revenue on which the tax was evaded resulted from the criminal conduct charged in the non-tax counts. See United States v. Roselli, 432 F.2d 879 (9th Cir.1970), cert. denied, 401 U.S. 924, 91 S.Ct. 883, 27 L.Ed.2d 828 (1971). The core of the tax count was the income extorted from Wedtech and Lawrence. Since a tax count deals with taxes evaded on a single year’s income, it was not error in this case to join the tax count, even though it included a relatively small amount of income from the unrelated transaction involving Fogliano. See United States v. McGrath, 558 F.2d 1102, 1106 & n. 6 (2d Cir.1977). That principle, however, has its limits. We would have a very different case if the Government had sought to join several defendants who all extorted benefits from Fogliano and then joined a tax count that charged Simon with evading taxes not only on income from Fogliano but also on income extorted from Wedtech. But where, as here, the Wedtech extortion is central to the trial and income from it forms the core of the tax count, that count need not be severed just because it includes a small amount of unreported income from other sources. We also reject Richard Biaggi’s claim that he was unfairly prejudiced by his joinder with defendants charged with the core of the Wedtech illegalities. He contends that he was placed in an untenable position of having to prove his membership in the firm of Biaggi & Ehrlich to justify his receipt of half of the five percent stock interest in Wedtech, thereby subjecting himself to the prejudicial effect of the evidence concerning the firm’s activities with which he was not personally involved. However, it is obvious that even in a separate trial much of the evidence concerning the activities of the firm and of Wedtech would have been admissible in evidence to prove the circumstances concerning the five percent stock transaction. II. Jury Selection Appellants make two challenges to the selection of the jury. Mariotta contends that the jury selection process used in the Southern District of New York unlawfully discriminates against Blacks and Hispanics, and he and Biaggi contend that the Government’s use of its peremptory challenges discriminated against Hispanics and Italian-Americans. A. The Southern District’s Jury Plan. The Southern District’s Jury Plan uses voter registration lists as the exclusive source of names of prospective jurors. After a two-day hearing, Judge Motley found the following facts pertinent to Mariotta’s claim that use of voter registration lists resulted in unlawful underrepresentation of Blacks and Hispanics. Based on 1984 figures, the percentage of Blacks in the population of the Southern District was 19.9, and the percentage of Blacks in the Master Jury Wheel for the Manhattan seat of court was 16.3. The comparable percentages for Hispanics were 15.7 and 11.0. The disparity for Blacks, i.e., the underrep-resentation, was 3.6 percentage points and for Hispanics, 4.7 percentage points. See United States v. Biaggi, 680 F.Supp. 641, 647, 652 (S.D.N.Y.1988). 1. Equal Protection Claim. Focusing first on the Fifth Amendment claim, based on the equal protection component of that amendment’s Due Process Clause, Judge Motley applied this Court’s analysis in Alston v. Manson, 791 F.2d 255, 257 (2d Cir.1986), cert. denied, 479 U.S. 1084, 107 S.Ct. 1285, 94 L.Ed.2d 143 (1987). Alston read Castaneda v. Partida, 430 U.S. 482, 97 S.Ct. 1272, 51 L.Ed.2d 498 (1977), to establish a three-part test for a prima facie case of jury discrimination amounting to a denial of equal protection: (a) a cognizable group (b) that is substantially underrepresented and (c) a selection procedure that is not racially neutral. Agreeing with Mariotta that the first two elements of the test were met, findings the Government does not contest on appeal, the District Judge rejected the equal protection challenge on the ground that use of the voter registration list as the sole source of prospective jurors had not been shown to deprive the Jury Plan of racial neutrality or render it susceptible to abuse. As Judge Motley pointed out, Mariotta made no claim that Blacks or Hispanics have been hindered in registering to vote. They have simply chosen not to register in the same proportion as Whites. That circumstance is quite different from the Texas “key man” selection system at issue in Castaneda or the Connecticut quota system favoring small towns with low minority populations at issue in Alston. Mariotta disputes that the unimpaired ability of Blacks and Hispanics to register is sufficient reason for tolerating underrepresen-tation resulting from use of voter lists. He relies on Alston and contends that in that case the minority populations in Connecticut’s larger communities could have rectified their underrepresentation on the jury lists by moving in greater numbers to small towns. But the issue does not turn on the physical capacity of minorities to increase their proportion on lists used as sources for prospective jurors. Giving up one’s community of residence is a major dislocation. Registering to vote is a simple task of minimal inconvenience, viewed by many as an obligation of citizenship. The Fifth Amendment challenge was properly rejected. 2. Sixth Amendment Claim. Mariotta also challenged the Jury Plan as a violation of his rights under the Sixth Amendment and the Jury Selection and Service Act of 1968, 28 U.S.C. §§ 1861— 1869 (1988). In Alston we recognized that a jury selection system yielding a significant underrepresentation of a minority group in jury venires can violate the “fair cross-section” requirement of the Sixth Amendment, even if proof of discriminatory intent necessary for a Fifth Amendment violation is absent. 791 F.2d at 258; see Duren v. Missouri, 439 U.S. 357, 368 n. 26, 99 S.Ct. 664, 670 n. 26, 58 L.Ed.2d 579 (1979). Judge Motley correctly observed that we arguably blurred that distinction in United States v. Young, 822 F.2d 1234, 1239-40 (2d Cir.1987), in rejecting a Sixth Amendment challenge to a venire drawn from voter lists. See United States v. Biaggi, 680 F.Supp. at 653-54. Yet, as she also pointed out, Young and Alston are reconcilable, id. at 654, and we agree with Judge Motley that discriminatory intent is not an element of a Sixth Amendment “fair cross-section” claim. The District Judge rejected Mariotta’s Sixth Amendment claim on the ground that the degree of underrepresentation was not great enough to violate the “fair cross-section” requirement. In reaching that conclusion, she applied the so-called “absolute numbers” approach, used by this Court in United States v. Jenkins, 496 F.2d 57 (2d Cir.1974), cert. denied, 420 U.S. 925, 95 S.Ct. 1119, 43 L.Ed.2d 394 (1975). In Jenkins, we deemed an underrepresentation too small to violate Sixth Amendment standards where proper representa tion would have required the addition of only one member of the minority group to a typical venire of 60 persons. Though the “absolute numbers” approach has been called into question, see Alston v. Manson, 791 F.2d at 259, we have recently reaffirmed its use. United States v. Rosario, 820 F.2d 584, 585 & n. 1 (2d Cir.1987); see Anderson v. Casscles, 531 F.2d 682, 685 & n. 1 (2d Cir.1976). The risk of using this approach is that it may too readily tolerate a selection system in which the seemingly innocuous absence of small numbers of a minority from an average array creates an unacceptable probability that the minority members of the jury ultimately selected will be markedly deficient in number and sometimes totally missing. Of course, the Sixth Amendment assures only the opportunity for a representative jury, rather than a representative jury itself, see Roman v. Abrams, 822 F.2d 214, 229 (2d Cir.1987), cert. denied,—U.S.-, 109 S.Ct. 1311, 103 L.Ed.2d 580 (1989); McCray v. Abrams, 750 F.2d 1113, 1124-25 (2d Cir.1984), vacated and remanded, 478 U.S. 1001, 106 S.Ct. 3289, 92 L.Ed.2d 705 (1986), but that opportunity can be imperiled if venires regularly lack even the small numbers of minorities necessary to reflect their proportion of the population. In this ease, Judge Motley found that addition of two Blacks and two to three Hispanics to a venire of typical size would be required to eliminate underrepre-sentation, and she concluded that these figures, though larger than those in Jenkins, “are not so great as to amount to a violation of the fair cross-section requirement.” United States v. Biaggi, 680 F.Supp. at 655. We think the facts of this case press the Jenkins “absolute numbers” approach to its limit, and would find the Sixth Amendment issue extremely close if the underrepresentations had resulted from any circumstance less benign than use of voter registration lists. Nevertheless, we agree with the conclusion reached by the District Court and reject the Sixth Amendment challenge. We also agree that rejection of the Sixth Amendment claim, in the circumstances of this case, necessarily requires rejection of the statutory claim. Id. at 657. B. The Government’s Peremptory Challenges. Mariotta contends that the Government used its peremptory challenges to exclude Hispanics, and Biaggi makes the same contention with respect to Italian-Americans. Defendants initially raised their claims immediately after the peremptory challenges were exercised. Judge Motley ordered the defendants to present their claims in written motions, a requirement the defendants acknowledged without objection. However, written motions were not submitted until after the conclusion of the trial. Judge Motley then held a two-day hearing at which one of the prosecutors was questioned extensively about the Government’s reasons for challenging members of the venire with Hispanic or Italian surnames. The District Judge ruled that the defendants had shown a sufficient pattern of Government use of peremptory challenges against Hispanics and Italian-Americans to constitute a prima facie case of discrimination, obliging the Government to demonstrate neutral explanations for its challenges. See Batson v. Kentucky, 476 U.S. 79, 106 S.Ct. 1712, 90 L.Ed.2d 69 (1986); United States v. Alvarado, 891 F.2d 439 (2d Cir.1989), vacated on other grounds, 58 U.S.L.W. 3815 (U.S. June 25, 1990). The Government had challenged four of the six Hispanics and five of the six Italian-Americans chosen for the regular jury, and two of the four Hispanics chosen for service as alternates. Judge Motley then found that the prosecution’s explanations for its challenges were neutral and not pretextual, and satisfactorily rebutted the claim of discrimination. These findings have considerable support in the record and are not clearly erroneous. See United States v. Biaggi, 853 F.2d 89, 96 (2d Cir.1988), cert. denied,—U.S.-, 109 S.Ct. 1312, 103 L.Ed.2d 581 (1989). Two aspects of the Batson claim merit brief additional comment. First, Batson objections should be entertained and adjudicated during the process of jury selection. Though the District Court’s preference for written motions in a complex trial is understandable, that preference must give way to the need to resolve a Batson claim at the point where prompt corrective action can be taken if the claim is successful. “We recognized in McCray [v. Abrams, 750 F.2d 1113 (2d Cir.1984),] and Roman [v. Abrams, 822 F.2d 214 (2d Cir.1987),] that the prosecutor’s unwarranted exclusion of cognizable groups should be remedied on the spot, without waiting to see the ultimate composition of the jury.” United States v. Alvarado, 891 F.2d at 445. Postponing consideration of a Batson claim until the trial is in progress, or even completed, as in this case, risks infecting what would have been the prosecutor’s spontaneous explanations with contrived rationalizations, and may create a subtle pressure for even the most conscientious district judge to accept explanations of borderline plausibility to avoid the only relief then available, a new trial. Cf. United States v. Tunnessen, 763 F.2d 74, 78 (2d Cir.1985) (requiring contemporaneous statement of “ends of justice” continuance under 18 U.S.C. § 3161(h)(8)(A) (1988) to guard against risk that district judge “may simply rationalize his action long after the fact”). The postponement of the Batson inquiry is no ground for complaint in this case, however, because the defendants did not object to the requirement of a written motion and did not present the motion until the end of the trial. Second, though we accept the District Court’s findings as to the prosecution’s neutral explanations, we reject the Government’s effort to bolster its denial of discrimination by showing how closely the ethnic composition of the jury resembled that of the venire from which it was selected. The composition of the jury may be relevant to rebutting a claim of discrimination in the trial court, see United States v. Biaggi, 673 F.Supp. 96, 107 (E.D.N.Y.1987), aff'd, 853 F.2d 89 (2d Cir.1988), cert. denied, —U.S.-, 109 S.Ct. 1312, 103 L.Ed.2d 581 (1989), bt the pertinent comparison is between the jury as selected and the racial or ethnic composition of the population of the judicial district, not the composition of the venire drawn for the particular case, id. The latter might contain an underrepresentation of a cognizable group compared to the pertinent population. Cf. United States v. Jenkins, 496 F.2d at 65. In this case, however, Hispanics were in fact 17.2 percent of the venire, compared to 15.7 percent of the Southern District population. III. Challenges to the Sufficiency of the Evidence A. The Five Percent Stock Interest. Richard Biaggi was convicted only of offenses related to the five percent stock interest. He was convicted (a) of aiding and abetting his father’s commission of bribery and gratuity offenses based on the stock interest, (b) of mail fraud based on fraudulent concealment of his father’s ownership of half of the five percent stock interest (112,500 shares), and (c) of filing false income tax returns by overstating his income to include on his 1983 return receipt of the 112,500 shares and on his 1985 return receipt of gain from the sale of one-third of these shares. He contends that the evidence is insufficient to show that he aided and abetted the bribery and gratuity offenses of his father that were based on the stock interest. For purposes of this appeal, he concedes that the evidence sufficed to show that the Congressman committed bribery and gratuity offenses with respect to the stock. His primary point is that there is insufficient evidence to show that he knew the stock was issued to influence his father in his official duties (bribery) or because of his father’s performance of official acts (gratuity). He also contends that the evidence is insufficient to show that he was holding the 112,500 shares as nominee for his father. Taking these claims in reverse order, we are satisfied that there was sufficient evidence that Richard was holding his father’s 112,500 shares as a nominee. The demands by Biaggi and by Ehrlich for Wedtech stock began in 1981. Moreno testified that when Ehrlich became aware of Moreno’s nine percent stock interest, he pressed Moreno to honor what he alleged was a prior promise by Mariotta to issue some stock to Biaggi & Ehrlich. In a conversation in, 1982, Biaggi made a demand for a five percent override on all contracts that he “could help bring into the company.” Wedtech officials rejected that demand, but suggested that they could pay the firm five percent of the subcontracts resulting from such contracts. At this meeting they agreed to issue five percent of Wedtech stock to the firm. There is no evidence that Richard Biaggi was present at or informed of any of the discussions at which the five percent stock interest was demanded or agreed to. In 1983, in anticipation of the public offering of Wedtech’s stock, Biaggi and Ehrlich pressed Wedtech to issue their promised stock interest. An early draft of the agreement for the share transfer provided that 225,000 shares (five percent) would be granted to the law firm of Biaggi & Ehrlich. Later in 1983, Biaggi, Ehrlich, and Richard met with Irwin Wolf, Biaggi’s tax accountant, to discuss how the 225,000 shares would be handled. Wolf testified that the law firm was to receive “fees in kind, namely, the stock of the corporation.” Wolf was asked whether the Congressman could retain ownership if the shares were issued in the name of the law firm. Wolf said that was not possible because the Congressman had sold his interest in the firm in 1979. Wolf was then asked about the consequences of placing the Congressman’s shares in his own name. Wolf said that, if that occurred, the issuance of the shares would be income to the Congressman in 1983 and that the receipt of such income might put him over the statutory cap on outside earnings. By House Rule XLVII, effective after December 31, 1978, that cap was 30 percent. After these alternatives were rejected, the conclusion was reached “that the stock would have to be registered in the name of Richard, because there didn’t seem to be any other alternative.” Thereafter, Ehrlich and Richard were each issued 112,500 shares. Evidence of events after the shares were received supports a finding that Richard was holding his father’s stock. In late 1983, when it was proposed that Richard transfer some of the shares to Mariotta to support his claim of Wedtech’s entitlement to section 8(a) eligibility, the Congressman decided that the shares would be transferred, despite Richard’s objection, and the Congressman dictated special terms, not applicable to other transferors, for the “default” provisions of the transfer to Mariot-ta. When Richard sold one-third of the shares in 1985, he retained nearly all the proceeds, after using enough for taxes, in a money market account paying approximately seven percent interest, even though he was then paying fourteen percent interest on two mortgage loans. Finally, the evidence undermined any claim that Richard could possibly have been entitled to the 112,500 shares as a member of the firm. When the stock was issued, he had been a lawyer for only nine months, he did little work on the Wedtech account, and he was not listed as a partner in the firm until 1985. Though the evidence amply supports a finding that Richard held the stock as nominee for his father, it fails to support a finding, crucial to Richard’s bribery conviction, that he knew the shares were issued for his father’s benefit in return for his father’s being influenced to assist Wed-tech as a Congressman. There was no evidence that Richard heard any of the statements that supported the finding that the stock was a bribe and an extortion, such as the Congressman’s demand for five percent of contracts he brought to Wed-tech, a demand that accompanied the negotiation of the five percent stock interest, and the threatening remark that the Congressman could destroy the company. The Government contends that Richard must have known that the shares were issued to his father for an unlawful purpose because, according to the Government, their value of $1,800,000 exceeded the value of any legal services rendered by the law firm. This speculation is unsupportable. Though the public offering price was $16 per share, the shares issued to Ehrlich and Richard contained a restriction precluding sale within two years. There is dispute as to the value of the restricted shares when issued, but there is no evidence that in 1983 anyone was willing to pay anything near $1,800,000 for 112,500 shares that could not be sold until 1985. The accountants who prepared the 1983 tax returns for Ehrlich and Biaggi valued the 112,500 shares at $34,000, apparently using a book value supplied by Wedtech. Even if the value in fact was somewhat higher, there is no evidence that the value was so high, in relation to the value of past services rendered by the firm, as to lead Richard to believe that the shares must have been issued for an unlawful purpose. There is sufficient evidence, unchallenged by Biaggi or Ehrlich, that they knew why the shares were issued. And it is possible that the Congressman told his son the true reason. But knowledge, though inferable from circumstances, must be based on evidence, not speculation. What little evidence exists as to Richard’s knowledge would have supported a finding that he knew that his father’s stock was put in his name to circumvent the limits on a Congressman’s outside income. Had Richard been charged with aiding and abetting a violation of that restriction, a conviction could stand. But the evidence did not permit a rational jury to find beyond a reasonable doubt that Richard knew that his father received the shares as a bribe or a gratuity, and without evidence of such knowledge, Richard’s conviction for aiding and abetting the bribery and the gratuity may not stand. See United States v. Zambrano, 776 F.2d 1091, 1097 (2d Cir.1985) (aider and abetter must have the mental state necessary to convict the principal); United States v. Perry, 643 F.2d 38, 46 (2d Cir.) (same), cert. denied, 454 U.S. 835, 102 S.Ct. 138, 70 L.Ed.2d 115 (1981). The reversal of these counts, however, does not affect Richard’s conviction on the two counts charging the filing of false income tax returns. Since the evidence sufficed to show Richard’s knowledge that the shares were owned by his father, he was properly convicted of overstating his income to include receipt of the shares and the subsequent profit from their sale. The false tax return counts require knowledge only of the true ownership of the shares, not of the unlawful purpose for which they were issued. As to the mail fraud count, the Government advises only that since Richard’s attack on his mail fraud conviction “rests” on his challenge to the bribery and gratuity convictions, it will not “address the mail fraud count separately.” Brief for Appellee at 63 n. *. This appears to concede that Richard’s mail fraud conviction cannot survive reversal of his bribery conviction, and the mail fraud conviction will therefore be reversed. Reversal of Richard’s bribery, gratuity, and mail fraud convictions results in vacation of the $51,000 in fines imposed on those counts but does not reduce his sentence since he received concurrent two-year sentences. Nevertheless, since the District Judge may well have regarded the tax return offenses as aggravated because of their relation to the bribery offense, we think there should be an opportunity for resentencing on the tax return counts, now that the bribery conviction has been reversed. See United States v. Sperling, 506 F.2d 1323, 1343 (2d Cir.1974), cert. denied, 420 U.S. 962, 95 S.Ct. 1351, 43 L.Ed.2d 439 (1975); United States v. Rizzo, 491 F.2d 1235, 1236 (2d Cir.1974). The Government contends that this opportunity for reconsideration of the sentence should not be afforded, pointing out that we have previously denied the Govern-merit’s request to permit reconsideration of a sentence- claimed to be lenient where conviction on a count carrying a more severe sentence is reversed. See United States v. Pisani, 787 F.2d 71 (2d Cir.1986). We are not persuaded that claims for reconsideration of sentences must be treated symmetrically. A sentencing judge has the option of imposing a sentence of adequate severity on a less serious count no matter what happens to the sentence on a more serious count. An opportunity to consider increasing a sentence on a minor count after a sentence on a major count is vacated is not required. See id. at 75-76. But the initial sentence on a comparatively minor count may well have been influenced upwards in part by a defendant’s conviction on serious charges, and the reversal of a conviction on such charges should afford an opportunity for consideration of a reduction of the sentences on the remaining counts, unless the sentencing judge’s intent to scale sentences according to the seriousness of the several offenses is clear. B. The $50,000 Loop Drive Payment. Ehrlich contends, in an argument that applies as well to Biaggi and Mariotta, that the evidence is insufficient to show that the $50,000 Loop Drive payment was unlawful. It is undisputed that Biaggi & Ehrlich billed Wedtech $50,000 for legal services rendered in connection with the leasing of the Loop Drive property from New York City. That payment formed the basis of Biaggi’s convictions for extortion, accepting a bribe, and mail fraud, Ehrlich’s convictions for aiding and abetting these offenses, and Mariotta’s conviction for bribing Biaggi. The mail fraud convictions rested on the alleged falsity of the law firm’s bill in stating that it was rendered for legal services. The issue as to the criminality of the payment is whether the demand for the payment was extortion by Biaggi and whether the payment was a bribe of Biaggi, as the Government contends, or whether the payment was sought and made lawfully as a fee for legal services, as appellants contend. The issue presents difficulties because this case is not the garden variety of extortion/bribery in which a payment is made to a public official who has no colorably lawful claim to it. Where a federal law enforcement officer is paid cash, for example, it will usually be clear that the payment is unlawful; the payment will at least be a gratuity if paid because of his official act, 18 U.S.C. § 201(c)(1)(B), it will be a bribe if paid in exchange for his being influenced in his duties, id. § 201(b)(2)(A), and it will be extortion if he demanded it under color of official right, id. § 1951(b)(2). However, a payment to a law firm is normally a legitimate payment for services rendered, and the payment does not necessarily become unlawful because the firm used its political contacts to assist its client in a matter that requires governmental approvals, in addition to rendering traditional legal services such as negotiating and drafting a lease. Distinguishing between a lawful fee and an unlawful bribe or extortion is further complicated in this case because the payment alleged to be a lawful fee was received by a firm with which Congressman Biaggi maintained an “of counsel” relationship and in which his son was initially employed and later a partner. In their approaches to the issue, both sides overstate their contentions. The Government asserts that the $50,000 “cannot be viewed as a simple request for compensation for services rendered” because the law firm “was already handsomely compensated by virtue of its $150,000 retainer.” Brief for Appellee at 56. Yet it is not uncommon in the practice of law for legitimate legal fees to be paid in addition to an annual retainer where a law firm handles special tasks and accomplishes significant results. In this case, it is undisputed that lawyers at the firm, particularly Ehrlich and his associate, Carlos Cuevas, Jr., performed legal tasks in negotiating the favorable terms of the Loop Drive lease and drafting its provisions. Though the work was done in a matter of days, it had to be done on an expedited basis and entailed long hours. The lawyers’ efforts obtained for their client a waterside property that was essential to performance of a multi-million dollar contract and did so at an annual saving in rent of $75,000 below the City’s asking price for the three-year lease. Appellants contend that the $50,000 was a proper legal fee earned by the firm— as lawful as the $5,000 bonus that Moreno gave to Cuevas, a payment the Government does not challenge. On the other hand, appellants overstate the matter in urging that the $50,000 was solely for services already rendered and therefore could not have satisfied either the quid pro quo element of a bribe or the inducement element of an extortion. The law firm’s bill was dated June 19, 1984. The demand for payment and Moreno’s agreement on behalf of Wedtech to pay the fee must have occurred before this date. After this date, important steps remained to be taken to assure Wedtech that the lease would be approved. When two members of the Board of Estimate, City Controller Harrison Goldin and Queens Borough President Donald Manes, objected at the Board’s June 13 meeting to expedited consideration of the lease the next day, efforts were made to secure approval at a subsequent meeting. Biaggi called Goldin and Simon, and Richard Biaggi asked Simon to talk to Manes. As reported by Ehrlich to Moreno, the Congressman believed that Simon was at fault for not getting the lease on the Board’s June 14 agenda, and he talked to Simon about obtaining approval at a subsequent meeting. In Moreno’s words, Biaggi “had punished [Simon] ... had told him that his next election depended on Mario Biaggi's support and that he had to start moving really quick.” The $50,000 bill was paid the day after the July 12 meeting of the Board of Estimate. It thus appears, and surely the jury was entitled to find, that the $50,000 payment had two purposes. It was sought in part as compensation for legal services rendered by the law firm. But in part it was also a payment demanded by Biaggi (and directed to his son’s firm) to obtain his assistance as a public official in securing favorable action from other public officials. Biaggi expected to be influenced by the payment to render such assistance, thereby satisfying the quid pro quo element of bribery and he obtained the payment, at least in part, by virtue of the action he could be expected to take as a Congressman, thereby satisfying the inducement element of extortion. Only two years previously, in connection with the demand for the five percent stock interest, Biaggi had reminded Wedtech officials that he had “brought up the company to the point it was” and “could also destroy it.” Thus, the issue as to the $50,000 payment becomes whether a payment may be found to constitute a bribe and an extortion where it is sought and paid for both lawful and unlawful purposes. We think it may. A valid purpose that partially motivates a transaction does not insulate participants in an unlawful transaction from criminal liability. For example, if a Congressman demands a payment for taking official action as to a matter that requires some legal services, his demand is nonetheless extortion if he instructs the payer to retain his son’s law firm for the needed legal services and to pay a sum for both the firm's legal services and his own official action. In such cases, however, the evidence must suffice to permit the jury to find beyond a reasonable doubt that the unlawful purposes were of substance, not merely vague possibilities that might attend an otherwise legitimate transaction. A client paying his law firm’s legal fee does not commit bribery simply because a Congressman is “of counsel” to the firm and the client hopes the Congressman will some day be helpful. In some cases of payments to service providers who hold public office, the evidence has been deemed insufficient to show any purpose for a payment other than a lawful one. See United States v. O’Keefe, 825 F.2d 314, 319-20 (11th Cir.1987). In the pending case, several factors permitted the jury to find the $50,-000 payment unlawful. It followed a prior extortionate demand by Biaggi and Ehrlich for a five percent stock interest. It was discussed with a Congressman while matters were pending on which the Congressman’s assistance was urgently needed. The bill was submitted just one week after the need for the Congressman’s assistance became apparent. The bill was paid the day after the governmental action on which the Congressman had assisted. The bill was not accompanied by normal law firm time records and, though perhaps justified in part by the legal services rendered, was in addition to a substantial retainer. Under all the circumstances the jury was entitled to conclude that the $50,000 was demanded and paid, at least in part, to obtain the political services of Congressman Biaggi. Though it would be helpful in cases like this, where a payment appears to have a lawful purpose in addition to its allegedly unlawful purpose, to focus the jury’s attention on the special problems presented by the possibilities of dual motivation, no special charge language was requested on this point. Appellants’ complaint is solely that the evidence was insufficient for conviction, and we conclude that it suffices. C. Neglia’s Bribery Offense. Neglia mounts a substantial challenge to his bribery conviction on the ground that the evidence showed at most a gratuity violation and did not establish the quid pro quo necessary to establish a bribery violation. See United States v. Myers, 692 F.2d 823, 841 (2d Cir.1982), cert. denied, 461 U.S. 961, 103 S.Ct. 2437, 77 L.Ed.2d 1322 (1983). A public official commits a gratuity violation when he accepts something of value, here the promise of a job, “for or because of any official act performed or to be performed.” 18 U.S.C. § 201(c)(1)(B). He commits a bribery violation when he accepts something of value “in return for (A) being influenced in the performance of any official act.” Id. § 201(b)(2). Neglia contends that the job was promised “in gratitude for past services.” Brief for Neglia at 69. Testimony of Moreno, Neuberger, and Shorten supports Neglia’s claim that the job was promised as a reward for prior assistance. The Government contends, however, that the job was promised not only as a reward for past services but also in return for being influenced in the performance of official duties in the future. We have recognized, especially with respect to public officials, that evidence of the receipt of benefits followed by favorable treatment may suffice to establish circumstantially that the benefits were received for the purpose of being influenced in the future performance of official duties, thereby satisfying the quid pro quo element of bribery. See United States v. Friedman, 854 F.2d 535, 554 (2d Cir.1988), cert. denied,—U.S.-, 109 S.Ct. 1637, 104 L.Ed.2d 153 (1989). After learning of the
