    United States of America v. Napout et. ano
    UNITED STATES COURT OF APPEALS
    FOR THE SECOND CIRCUIT

    v.
    JUAN ÁNGEL NAPOUT, JOSÉ MARIA MARIN,
    Defendants-Appellants. 1
    Before:            SACK, HALL, AND BIANCO, Circuit Judges.
    Defendants-appellants Juan Ángel Napout and José Maria Marin, former
    officials of the global soccer organization Fédération Internationale de Football
    Association ("FIFA"), were each convicted of, inter alia, multiple counts of
    conspiracy to commit honest services wire fraud after a trial in the United States
    District Court for the Eastern District of New York (Pamela K. Chen, Judge). On
    appeal from the judgments of conviction, Napout and Marin argue principally that
    their convictions rest upon impermissible extraterritorial applications of the

    honest services wire fraud statute, 18 U.S.C. § 1346. They argue also that § 1346 is
    unconstitutionally vague as applied to them. We conclude that the appellants'
    convictions involve domestic applications of § 1346 that are sufficiently clear
    under the circumstances. Accordingly, the judgments of the district court are
    AFFIRMED.
    JUDGE HALL filed a concurring opinion.

    SACK, Circuit Judge:
    INTRODUCTION
    Defendants-appellants Juan Ángel Napout and José Maria Marin, former
    officials of the global soccer organization Fédération Internationale de Football
    2
    Association, or "FIFA" (pronounced fee-fa), were each convicted of, inter alia,
    multiple counts of conspiracy to commit honest services wire fraud after a trial in
    the United States District Court for the Eastern District of New York (Pamela K.
    Chen, Judge). On appeal from the judgments of conviction, Napout and Marin
    argue principally that their convictions rest upon impermissible extraterritorial
    applications of the honest services wire fraud statute, 18 U.S.C. § 1346. They argue
    also that § 1346 is unconstitutionally vague as applied to them.
    Because appellants Marin and Napout appeal their convictions following a
    jury trial, we recount the facts viewing the evidence adduced in the district court
    in "'the light most favorable to the government, crediting any inferences that the
    jury might have drawn in its favor.'" United States v. Rosemond, 
    841 F.3d 95
    , 99–100
    (2d Cir. 2016) (quotation and citation omitted).          But we note that in the
    introduction to his brief on this appeal, appellant Napout 2 declares:
    2 In addition to adopting Napout's brief to the extent it is applicable to him, Marin
    Br. at 3, n.2, Marin objects on appeal to: (1) the district court's use of an anonymous
    and partially sequestered jury; (2) its ruling in limine, later reversed, as to the
    admissibility of foreign law; and (3) the admissibility of certain expert testimony.
    Conversely, Napout adopts Marin’s brief to the extent applicable to him as well.
    Napout Br. at 19, n.8. For this reason, we consider the arguments made by the two
    appellants as having been made by both, even when not adopted explicitly in their
    individual briefs.
    3
    This case raises one overarching question: by what authority does the
    United States purport to police the relationship between a
    Paraguayan employee and his Paraguayan employer, and an alleged
    scheme involving South Americans that took place almost entirely in
    South America. The answer: there is no such authority.
    Napout Br. at 1. Thus Napout makes clear the central theme of the appellants'
    argument on appeal: Even if they did as the government alleged, and the jury so
    found, as a matter of American statutory and constitutional law, they were not
    guilty of the crimes for which they were charged.

    Most Americans (and some others) refer to what we understand to be
    "association football" as "soccer." In most of the rest of the world, of course, it is
    called simply "football" (spelled "fútbol" in Spanish). 3 By any name, it is the
    3The "word 'soccer' comes from the use of the term 'association football' in Britain
    and goes back 200 years. . . . One variant of the game [that was played with one's
    hands] became 'rugby football.' Another variant [which was played with one's
    feet] came to be known as 'association football' after the Football Association
    formed to promote the game in 1863, 15 years after the rules were made at
    Cambridge. 'Rugby football' became ruggle' for short. 'Association football'
    became 'soccer.'" Tony Manfred, The Real Reason We Call It 'Soccer' Is All England's

    https://www.businessinsider.com.au/why-americans-call-it-soccer-2014-6. It may be
    worth noting, in the context of this appeal, that the term "association football" is
    included in the name of one of the two continent-wide associations involved in
    this prosecution, CONCACAF: the "North American Confederation of North,
    Central American and Caribbean Association Football."

    world's most popular sport. 4 Known in some quarters as the "Beautiful Game," 5
    much of the activity surrounding organized soccer, including in particular efforts
    to profit from the game's largest tournaments, has created widespread
    opportunities for corruption. The major, largely successful criminal prosecutions
    that included those in the case here on appeal reflect the fact that those
    opportunities are sometimes taken advantage of by people associated with the
    sport.
    These allegations of corruption have been associated with the operation of
    soccer's Zurich, Switzerland-based international governing body, FIFA, and some
    of its regional affiliates in North, Central, and South America, particularly la
    Confederación Sudamericana de Fútbol ("CONMEBOL"), and the Confederation

    half of the world's population consider themselves to be association football

    of North, Central America and Caribbean Association Football ("CONCACAF").
    Specifically at issue in this case are the bribes and kickbacks paid in connection
    with the process by which FIFA and its regional associates sell broadcasting and
    marketing rights to their more popular tournaments. Beginning at least as early
    as the 1980s, FIFA officials, including leaders of CONMEBOL, CONCACAF, and
    other such continental and national associations, accepted many millions of
    dollars in bribes from sports media and marketing companies in return for their
    granting those companies broadcasting and marketing rights to tournaments
    under the leaders' control.
    In May 2015, after nearly five years of investigation by, inter alia, the United
    States Internal Revenue Service (the "IRS"), the United States Federal Bureau of
    Investigation (the "FBI"), and the United States Attorneys' Office for the Eastern
    District of New York, the latter secured indictments against nine FIFA officials and
    five executives from sports marketing and media companies, for, among other
    things, racketeering conspiracy, wire fraud and wire fraud conspiracy, and money
    laundering and money laundering conspiracy, arising out of alleged bribery
    schemes connected to FIFA's tournaments. United States v. Webb et al., No. 15-cr-
    6
    00252 (E.D.N.Y. May 20, 2015), ECF No. 1, App. at 42. 6 Some six months later, in
    November 2015, the government filed a superseding indictment charging all but
    three of the original defendants, along with sixteen additional FIFA officials, with
    similar crimes arising out of the same schemes. United States v. Webb et al., No. 15-
    cr-00252 (E.D.N.Y. Nov. 20, 2015), ECF No. 102, App. at 48–49. 7
    In June 2017, after most of the charged defendants had pleaded guilty, some
    of them having cooperated with prosecutors and investigators, the government
    filed a second superseding indictment including as named defendants just three
    officials of South American regional and national organizations: Manuel Burga,
    the former president of Peru's national soccer federation; Juan Ángel Napout, the
    former president of Paraguay's national soccer federation; and José Maria Marin,

    a former head of the Brazilian national soccer federation. The second superseding
    indictment alleged one count of racketeering conspiracy against Burga; one count
    of racketeering conspiracy, two counts of wire fraud conspiracy, and two counts
    of money laundering conspiracy against Napout; and one count of racketeering
    conspiracy, three counts of wire fraud conspiracy, and three counts of money
    laundering conspiracy against Marin.
    Burga, Napout, and Marin all proceeded to trial in the district court
    beginning on November 6, 2017. On December 22, 2017, after six weeks of trial
    and five days of jury deliberations, the jury returned its verdicts. Burga was
    acquitted of the one count against him; Napout was convicted of the racketeering
    conspiracy and wire fraud conspiracy counts but acquitted on the money
    laundering conspiracy counts; and Marin was convicted on all counts but one, a
    money laundering conspiracy count on which he was acquitted.
    On August 22, 2018, the district court sentenced Marin to 48 months'
    imprisonment and two years' supervised release.        A week later, the court
    sentenced Napout to 108 months' imprisonment and two years' supervised
    release.
    8
    On appeal, Marin and Napout challenge their convictions for honest
    services wire fraud conspiracy on two principal grounds. First, they contend that
    the honest services wire fraud statute criminalizes only fraudulent conduct that
    occurs on U.S. — not foreign — soil and therefore cannot support convictions
    based on conduct, such as theirs, that occurred overseas. Second, they argue that
    it is unclear whether the honest services wire fraud statute criminalizes a breach
    of the fiduciary duty that a foreign employee owes to his foreign employer, and
    therefore that the lack of clarity leaves the statute unconstitutionally vague as
    applied to them.
    For the reasons set forth below, we conclude that these and the appellants'
    other arguments on appeal are without merit. We therefore affirm the judgments
    of the district court.
    BACKGROUND
    I. World Soccer/Football: General Background
    The Fédération Internationale de Football Association (popularly known
    and hereinafter referred to as "FIFA") is a Zurich, Switzerland-based entity
    responsible for governing the sport of what Americans call "soccer." Test. of
    Stephanie Maennl, Trial Tr. at 106. Two hundred eleven associations world-wide,
    9
    each governing some part of the game in a particular region, country, or territory,
    are members of FIFA.
    Id. FIFA's member
    associations are grouped into six continental confederations
    covering, inter alia, all continents except (of course) Antarctica.
    Id. at 110.
    "The
    Confederation of North, Central American and Caribbean Association Football,"
    or "CONCACAF," referred to above, consists of 35 national associations; the South
    American confederation, also referred to above, including an association from
    every country on that continent save for Suriname and Guyana, is known as "la
    Confederación Sudamericana de Fútbol," or "CONMEBOL."
    Id. at 110–13.
    FIFA and its members are governed by sets of rules called codes of ethics.
    Id. at 138.
    As relevant here, FIFA's lengthy and detailed code of ethics provides
    that the organization's officials "have a fiduciary duty to FIFA, the [continental]
    confederations, [and the national] associations." FIFA Code of Ethics (2012 ed.),
    Art. 15. In a section entitled "[b]ribery and corruption," the code provides that
    FIFA officials "must not offer, promise, give or accept any personal or undue
    pecuniary or other advantage . . . for the execution or omission of an act that is
    related to their official activities and is contrary to their duties or falls within their
    discretion."
    Id., Art. 21.
    10
    CONMEBOL's code of ethics is modeled on FIFA's and also requires the
    confederation's officials to act with "absolute loyalty, particularly to CONMEBOL
    [and] FIFA[.]" CONMEBOL Code of Ethics (2013 ed.), Art. 15. The code also
    provides that CONMEBOL officials "may not offer or promise or give or accept
    any improper personal or economic benefit or any other type of benefit, in order
    to obtain or maintain a transaction or any other dishonest benefit with respect to
    any CONMEBOL person or person outside CONMEBOL."
    Id., Art. 21.
    One of FIFA and the confederations' principal functions is to promote soccer
    by organizing international competitions. The most prominent is the World Cup,
    a quadrennial tournament among the leading national teams of the six continental
    confederations. Since its inception in 1930, with the World War II exceptions of
    1942 and 1946, it has taken place in various locations around the globe. 8
    CONMEBOL also holds tournaments the first of which preceded the first
    World Cup. Since 1916, 9 the confederation has organized the Copa América, a

    9"To celebrate the centenary of its independence on 9 July 1816 . . . , Argentina
    organized a tournament of 2 to 17 July 1916 with Chile, Uruguay and Brazil. This
    Campeonato Sudamericano of Selecciones (South American Championship of
    11
    quadrennial event now held in non-World Cup years in which national teams
    from each of CONMEBOL's ten countries, in addition to two national teams
    invited from outside the region, compete to be crowned champion of South
    America. Test. of Stefan Szymanski, Trial Tr. at 168, 183–84.
    CONMEBOL also hosts an annual tournament called the Copa Libertadores
    among the most successful local club teams in South America. Club teams qualify
    for the Copa Libertadores either by finishing above a specified level in the
    standings of their country's premier league or by winning their country's annual
    club tournament. In Brazil, for example, five clubs secure bids to the Copa
    Libertadores each year: the top four finishers in the country's premier league, the
    Campeonato Brasileiro Série A; and the winner of the annual Copa do Brasil
    tournament, organized by Brazil's national soccer organization, the Confederação
    Brasileira de Futebol ("CBF").
    These tournaments are immensely popular. For example, according to
    FIFA, approximately 3.57 billion people — more than half of the world's
    population over the age of four — watched some part of the 2018 World Cup. More

    2018), www.fifa.com/worldcup/news/more-than-half-the-world-watched-record-breaking-
    2018-world-cup. This popularity creates fertile ground for business.
    Between 2011 and 2014, FIFA generated approximately $5.718 billion in
    revenue, largely from sums paid by television broadcasting companies for the
    right to broadcast the organization's tournaments. Test. of Stephanie Maennl, Trial
    Tr. at 133–34. In 2014 alone, for example, FIFA generated nearly $743 million in
    revenue from the sale of television broadcasting rights.
    Id. FIFA also
    generates hundreds of millions of dollars in annual revenue by
    selling "marketing" rights connected with its tournaments. They include, among
    other things, the right to advertise on stadium billboards and team jerseys; the
    right to sponsor tournaments; and the right to license images, names, and other
    forms of intellectual property related to tournaments.
    To facilitate the sale of both broadcasting and marketing rights, FIFA and
    the confederations frequently hire sports media and marketing companies to serve
    as intermediaries between them and the various entities that wish to purchase the
    rights in order to exercise them. Test. of Stefan Szymanksi, Trial Tr. at 184–85. The
    companies, which specialize in selling rights connected to soccer tournaments, are
    13
    able to obtain higher prices for the rights than would FIFA or the confederations
    acting on their own.
    Id. at 185–86.
    To select among competing sports media and marketing companies, FIFA
    and the confederations typically rely on a tender process whereby companies
    submit bids to the soccer organizations arguing why they would be best suited to
    serve as an intermediary in a particular circumstance.
    Id. at 187.
    II. Alleged Corrupt Practices.
    A. The Parties.
    Beginning at least as early as the 1980s and continuing through the mid-
    2010s, the process for selling both broadcasting and marketing rights to many of
    FIFA's tournaments became rife with corruption, as reflected in part by the
    successful prosecutions in the district court of persons associated with the
    organization. Officials of FIFA, CONCACAF, and CONMEBOL, including the
    leaders of many of the related national associations, accepted millions of dollars in
    bribes from sports media and marketing companies in return for arranging for
    those companies to receive broadcasting and marketing rights in connection with
    tournaments under the leaders' control.
    14
    In particular, according to the indictments in the case at bar, three South
    American companies routinely undertook schemes to bribe CONMEBOL officials
    in return for the officials awarding them exclusive broadcasting and marketing
    rights to CONMEBOL tournaments. The indictment identifies the companies as
    Torneos y Competencias S.A. ("Torneos"), an Argentinian media business that
    operates television stations throughout Latin America, United States v. Webb et al.,
    No.15-cr-00252 (E.D.N.Y. Nov. 20, 2015), Second Superseding Indictment (the
    "S.S.I."), ECF No. 604 at 13, ¶ 33; Traffic Group ("Traffic"), a multi-national sports
    marketing company headquartered in São Paulo, Brazil,
    id. at 14,
    ¶ 37; and Full
    Play Group S.A. ("Full Play"), a sports marketing company headquartered in
    Buenos Aires, Argentina,
    id. at 17-18,
    ¶ 47.
    B.    The Schemes
    1.     The Copa América Scheme. The largest corrupt scheme was related
    to the Copa América tournaments.         Between 1987 and 2010, Traffic had an
    agreement with CONMEBOL for the exclusive broadcasting and marketing rights
    to the Copa América.
    Id. at 33–34,
    ¶ 90. In order to secure that agreement, and to
    maintain its relationship with CONMEBOL thereafter, Traffic paid bribes to
    15
    various CONMEBOL officials, including the confederation's president, Nicolas
    Leoz.
    Id. In 2010,
    CONMEBOL ended its relationship with Traffic.
    Id. at 34,
    ¶ 91.
    Sometime that year, Full Play, led by its controlling principals, father-and-son
    Hugo and Mariano Jinkis, began negotiating with CONMEBOL to take over as the
    exclusive rights holder for the Copa América tournament. Test. of Luis Bedoya,
    Trial Tr. at 1581. As part of the negotiations, Mariano Jinkis offered bribes of $1
    million to the presidents of the smaller national associations of Bolivia, Colombia,
    Ecuador, Paraguay, Peru, and Venezuela, who had formed a coalition — known
    as the "Group of Six" — to attempt to wrest power within CONMEBOL from the
    historically dominant nations of Argentina, Brazil, and Uruguay. S.S.I. at 13, ¶ 33,
    App. at 204. At that time, appellant Juan Ángel Napout was the president of the
    Paraguayan national association, the Asociación Paraguaya de Fútbol ("APF"), and
    the later-acquitted Manuel Burga was the president of the Peruvian national
    association, the Federación Peruana de Fútbol ("FPF").
    Id. at 33–34,
    ¶ 90, App. at
    203–04.
    Apparently as a result of Jinkis's offer of bribes, in June 2010, CONMEBOL
    entered into an agreement to provide Full Play with the exclusive broadcasting
    16
    and marketing rights to the 2015, 2019, and 2023 editions of the Copa América.
    Id. at 34,
    ¶ 91; Text of Translation of Agency Agreement Between CONMEBOL and
    Full Play Group, S.A. (June 8, 2010), App. at 809–19.
    In the following year, 2011, Traffic filed a lawsuit in Florida state court
    against CONMEBOL and Full Play alleging that their 2010 agreement had violated
    CONMEBOL's contract with Traffic. S.S.I. at 34, ¶ 92. To resolve the suit, Traffic
    and Full Play agreed to form, with Torneos, a joint-venture named Datisa
    Incorporated, of which each company would own a one third interest. Test. of
    Alejandro Burzaco, Trial Tr. at 416, App. at 441.
    CONMEBOL and Full Play then terminated their contract, and in May 2013,
    CONMEBOL, Datisa, and Full Play reached an agreement providing Datisa with
    the exclusive rights to the 2015, 2019, and 2023 editions of the Copa América.
    Purchase Contract Among CONMEBOL, Datista and Full Play (May 25, 2013),
    App. at 860.    The agreement also gave Datisa exclusive rights to a special
    centennial edition of the Copa América scheduled to be played in 2016 in stadiums
    across the United States.
    Id. In exchange
    for the rights, Datisa agreed to pay
    CONMEBOL $80 million for each edition of the tournament.
    Id. Datisa also
    agreed to pay bribes ranging from $1–$3 million for each edition of the
    17
    tournament, in addition to a bonus payment of $1–$3 million, to the presidents of
    each of CONMEBOL's national associations except for Uruguay, an expansion
    from Traffic's practice of bribing only the presidents in the Group of Six. Test. of
    Alejandro Burzaco, Trial Tr. at 418–20, Gov't App. at 149. The bribes Datisa gave
    to the leadership of the Brazilian association, the CBF, were complicated by the
    fact that the association's former president, Ricardo Teixeira, had resigned from
    his position in the spring of 2012 after learning he was under criminal investigation
    for corruption in Switzerland and Brazil. Following Teixeira's resignation, Datisa
    began splitting their bribes to the CBF between appellant Marin, a former
    politician from São Paulo who had replaced Teixeira as CBF president, and Marco
    Polo Del Nero, who had replaced Teixeira on a FIFA leadership committee. 10 Test.
    of Alejandro Burzaco, Trial Tr. at 352–53, 419; see also Test. of Eladio Rodrigues,
    Trial Tr. at 2363.
    Like other CONMEBOL officials, Marin worked with Full Play, Traffic, and
    Torneos to keep his bribe payments secret. The money destined for him would
    frequently be deposited in a Swiss bank account of a Torneos-controlled shell
    company. Test. of IRS Special Agent Berryman, Trial Tr. 3430–40, App. at 594–95;
    10 Upon Teixeira's resignation, Marin and Del Nero arranged for Del Nero to
    succeed Marin as CBF president in 2015.

    would be sent from the Swiss bank to an Andorran bank account controlled by
    Marin's associate, Wagner Abrahao.
    Id. Abrahao would
    then send installments
    from another of his Andorran bank accounts to a Morgan Stanley bank account in
    New York that Marin had opened in 2012 under the name "Firelli International
    Limited," a shell company he owned and controlled for his own benefit.
    Id. 2. The
    Copa Libertadores Scheme. CONMEBOL's Copa Libertadores
    tournament was similarly subjected to bribery. Starting at least as early as 2006,
    Torneos paid annual bribes to CONMEBOL officials in exchange for the officials
    providing a Torneos affiliate, T&T Sports Marketing Ltd., with exclusive rights to
    broadcast Copa Libertadores matches on television. Test. of Alejandro Burzaco,
    Trial Tr. at 252, 295. In the scheme's earliest years, according to Torneos's Chief
    Executive Officer Alejandro Burzaco, annual bribes of $600,000 were paid to Leoz
    and five other CONMEBOL officials, including Teixeira.
    Id. In March
    2008,
    CONMEBOL extended T&T's contract and sold to the company broadcasting
    rights to the 2014 through 2018 editions of the tournament.
    Id. at 310–11.
    Burzaco
    continued to pay bribes of between $500,000 and $1 million to the same six
    19
    CONMEBOL officials.
    Id. at 313–14.
    In 2010, Burzaco began paying annual bribes
    to, in addition to the six officials, the Group of Six presidents.
    Id. at 339.
    11 Two
    years later in December 2012, after a vote by the organization's leadership,
    CONMEBOL extended T&T's contract through 2022.                 Agreement Between
    CONMEBOL and Torneos (Dec. 20, 2012), App. at 771–78. Burzaco continued to
    pay CONMEBOL officials, including the appellants Napout, and Marin, annual
    bribes of between $300,000 and $1.2 million. Test. of Alejandro Burzaco, Trial Tr.
    at 329–30, 339, 574.
    3.    The Copa do Brasil Scheme
    There were also bribes paid in connection with CONMEBOL's domestic
    soccer tournaments. For example, between 1990 and 2009, Traffic, through its
    owner José Hawilla, paid yearly bribes to Teixeira to obtain a series of contracts
    for the broadcasting and marketing rights for the Copa do Brasil. S.S.I. at 43, ¶ 116.
    The last of these, executed in 2009, provided Traffic with those rights to the 2009
    through 2014 editions of the Copa do Brasil.
    Id. at 43–44,
    ¶ 117.
    In 2011, Klefer Produções e Promoções Ltda. ("Klefer"), a sports-marketing
    company, made payments to Teixeira to induce him to enter into an agreement
    Burzaco began splitting Teixeira's bribe payment between Marin and Del Nero
    11
    when Teixeira resigned in 2012, as Datisa had for the Copa América.
    Id. at 353.
    20
    with Klefer on behalf of CBF. Under the agreement, CBF provided Klefer with the
    rights for the 2015 through 2022 editions of CBF's Copa do Brasil.
    Id. at 45,
    ¶ 118;
    see also Test. of Jose Schettino, Trial Tr. at 2573–77.
    In 2012, Traffic and Klefer agreed to pool the marketing rights for the 2013
    through 2022 editions of the Copa do Brasil; they also agreed to share the cost of
    the bribe payments to be made to CBF officials. S.S.I. at 45, ¶ 118. When Teixeira
    resigned from the CBF in 2012, Traffic and Klefer began paying annual bribes of
    500,000 Brazilian Reais (approximately $211,864) to both Marin and Del Nero, like
    Datisa and Torneos had done in connection with the international tournaments.

    4.     The Paraguayan World Cup Qualifying Scheme
    CONMEBOL officials also solicited and received bribes in return for
    broadcasting and marketing rights for the "qualifying" matches to be played by
    various CONMEBOL national teams in the run up to the 2014 and 2018 World
    Cups. In Paraguay, for example, during October 2011, the APF agreed to sell the
    rights to its national team's 2014 and 2018 qualifying matches to Ciffart Sports S.A.
    21
    ("Ciffart"), an intermediary for Full Play. Test. of Santiago Peña, 12 Trial Tr. at 1167–
    71, Gov't App. at 123–27. In order to obtain these rights, Full Play agreed to pay
    Napout, then-president of the APF, bribes of $1 million for the matches related to
    the 2014 tournament and $1.5 million for those related to the 2018 tournament.
    Id. at 1172–73,
    Gov't App. at 128–29, 400 (the "Peña Ledger").
    Like Marin, Napout arranged to receive payments discreetly, or — as he
    referred to it— in a "safe way." Test. of Luis Bedoya, Trial Tr. at 1584. To keep
    Napout's involvement in the schemes from public view, Full Play would typically
    wire money from a United States bank account held in the name of a Seychelles
    company to an unrelated third party selected by a "cambista" (money changer);
    the third party would then deliver American cash to a "safety box" in Full Play's
    office, and Mariano Jinkis would then personally deliver the cash to Napout in
    Buenos Aires, usually meeting him in the Hilton hotel there. Test. of Santiago
    Peña, Trial Tr. at 1160–64, Gov't App. at 116–20. On occasion, Full Play also bribed
    Napout with concert tickets and a luxury vacation apartment in Punta del Este,
    12Santiago Peña, a cooperating witness described by Marin as a co-conspirator,
    Marin Br. at 12, had been an employee of Full Play, Test. of Santiago Peña, Trial
    Tr. at 1047. As explained by the government in its brief, "At trial, the government
    introduced a secret ledger of bribes paid to various soccer officials that was
    maintained by Full Play’s financial manager, Santiago Peña." Gov't. Br. at 10.

    States bank.

    C.    Indictments and Arrests
    In May 2015, a grand jury in the United States District Court for the Eastern
    District of New York handed down an indictment charging nine CONCACAF and
    CONMEBOL officials, including Marin, and five executives from sports marketing
    and media companies, with, among other things, racketeering conspiracy, wire
    fraud and wire fraud conspiracy, and money laundering and money laundering
    conspiracy. United States v. Webb et al., No.15-cr-00252 (E.D.N.Y. May 20, 2015),
    ECF No. 1, App. at 42. The charges in the 47-count indictment arose out of the
    bribery schemes connected to the tournaments in violation of various laws of the
    United States. On May 27, 2015, Marin was arrested by Swiss authorities while he
    was in Zurich for FIFA-related meetings. United States v. Webb et al., No.15-cr-
    00252 (E.D.N.Y. Aug. 6, 2018), Letter in Support of CONMEBOL's Request for
    Restitution, ECF No. 968 at 6, App. at 1541. By the time of his arrest, Marin had
    23
    received more than $3 million in payments in connection with the Copa América,
    Copa Libertadores, and Copa do Brasil schemes.13
    Napout, who by that time had begun serving as CONMEBOL's president,
    was not named in the original, May 2015, indictment. In the weeks following the
    filing of that indictment, he undertook efforts to hide the evidence of his
    involvement. United States v. Webb et al., No.15-cr-00252 (E.D.N.Y. Oct. 17, 2017),
    Sealed Memo. & Order Granting Gov't Mot. for Partially Anonymous and Semi-
    Sequestered Jury, ECF No. 717. He hired an attorney to represent him in his
    personal capacity and instructed the attorney to hire another attorney — whom
    Napout had selected — to represent CONMEBOL.
    Id. at 3.
    Soon thereafter,
    Napout learned that he was a target of the U.S. government's ongoing
    investigation and instructed his personal attorney to enter into a common-interest
    agreement with CONMEBOL's attorney in an effort to shield Napout from
    criminal liability by controlling the material that CONMEBOL would turn over to
    the government.
    Id. at 7–8.
    13 See, e.g., United States v. Webb et al., No.15-cr-00252 (E.D.N.Y. Sept. 11, 2018),
    Judgment, ECF No. 1015 at 8, Gov't Special App. at 16 (ordering forfeiture in the
    amount of $3,335,593).
    24
    On November 3, 2015, after five months of incarceration in Switzerland,
    Marin was extradited to the United States and released here on bond.            On
    November 25, the government filed a superseding indictment charging all but
    three of the original defendants, along with sixteen additional officials of
    CONCACAF and CONMEBOL, including Burga and Napout, with participating
    in the racketeering, money laundering and wire fraud conspiracies. United States
    v. Webb et al., No.15-cr-00252 (E.D.N.Y. Nov. 25, 2015), Sealed Indictment of, inter
    alia, José Maria Marin, Juan Ángel Napout, and Manuel Burga, ECF No. 102, App.
    at 48–49.
    On December 3, 2015, Napout was arrested also while in Zurich for FIFA-
    related meetings. By that time, Napout had, like Marin, received more than $3
    million in bribes in connection with the Copa América, Copa Libertadores, and
    Paraguayan World Cup qualifying matches. 14 Later that day, the CONMEBOL
    attorney who had been hired by Napout after the first group of officials were
    arrested in May, entered Napout's CONMEBOL office, and, acting pursuant to
    Napout's instructions, removed a computer that Napout knew contained material
    14 See, e.g., United States v. Webb et al., No.15-cr-00252 (E.D.N.Y. Sept. 4, 2018),
    Judgment, ECF No. 1008 at 8, Gov't Special App. at 8 (ordering forfeiture in the
    amount of $3,347,025.88); see also Gov't App. at 400 (Peña Ledger listing payments
    made to Napout).

    relevant to the government's investigation, including evidence of Napout's
    relationship with defendants charged in the original indictment and evidence that
    he had accepted bribes. United States v. Webb et al., No.15-cr-00252 (E.D.N.Y. June
    22, 2018), Memorandum & Order Regarding Post-Trial Motions, ECF No. 952 at
    28–29,     Special App. at 88–92.   Several weeks after his arrest, Napout was
    extradited to the United States by Swiss authorities and, upon arrival, released on
    bond.
    A year and a half later, on June 14, 2017, after most of the defendants
    charged in the superseding indictment pleaded guilty to the charges, some of them
    having cooperated with prosecutors and investigators, the government filed a
    second superseding indictment naming only three defendants: Burga, Marin, and
    Napout. S.S.I., App. at 170–227. This second superseding indictment contained
    seven counts:
    1.    Count One charged Burga, Marin, and Napout with
    racketeering conspiracy in violation of 18 U.S.C.
    § 1961(1) and (5).
    2.    Count Two charged Marin and Napout with
    honest services wire fraud conspiracy arising out of the
    Copa Libertadores tournament, in violation of
    18 U.S.C. § 1349.
    3.    Count Three charged Marin and Napout with money
    26
    laundering conspiracy arising out of the Copa Libertadores
    tournament, in violation of 18 U.S.C. § 1956(h).
    4.      Count Four charged Marin with honest services
    wire fraud conspiracy arising out of the Copa do
    Brasil tournament, in violation of 18 U.S.C. § 1349.
    5.      Count Five charged Marin with money laundering
    conspiracy arising out of the Copa do Brasil tournament,
    in violation of 18 U.S.C. § 1956(h).
    6.      Count Six charged Marin and Napout with honest services
    wire fraud conspiracy arising out of the Copa América
    tournament, in violation of 18 U.S.C. § 1349.
    7.      Count Seven charged Marin and Napout with money
    laundering conspiracy arising out of the Copa América
    tournament, in violation of 18 U.S.C. § 1956(h).
    D.    Trial
    Napout, Marin, and Burga proceeded to trial before a partially anonymous
    and sequestered jury 15 beginning on November 6, 2017. After six weeks of trial
    and five days of deliberations, on December 22, 2017, the jury returned its verdict.
    Burga was acquitted of the only count against him; Napout was convicted on the
    racketeering conspiracy and wire fraud conspiracy counts but acquitted of the
    15The jurors' names were made available to the parties and their attorneys but
    were concealed from the public. The jurors were sequestered insofar as they were
    escorted into and out of the courthouse by U.S. Marshals and were transported
    from the courthouse to a central location each day before returning home. They
    were also sequestered during breaks in the trial, including lunchtime.
    27
    money laundering conspiracy counts; and Marin was convicted on all counts
    except for one count of money laundering conspiracy.
    On August 22, 2018, the court sentenced Marin to 48 months' imprisonment
    and two years' supervised release, and ordered him to pay a fine of $1.2 million
    and approximately $3.34 million in forfeiture. On August 29, the court sentenced
    Napout to 108 months' imprisonment and two years' supervised release; the court
    also ordered Napout to pay a fine of $1 million and approximately $3.35 million
    in forfeiture. Both Marin and Napout appeal.
    DISCUSSION
    A.     Extraterritoriality
    On appeal, the appellants principally contend that their convictions for
    conspiracy to commit honest services wire fraud were based upon impermissible
    extraterritorial applications of the wire fraud conspiracy statute. We review such
    questions of statutory interpretation de novo. See, e.g., United States v. Epskamp, 
    832 F.3d 154
    , 160–62 (2d Cir. 2016).
    As a general matter, statutes are presumed to "have only domestic
    application." RJR Nabisco, Inc. v. European Cmty, 
    136 S. Ct. 2090
    , 2100 (2016) (citing
    Morrison v. Nat'l Australia Bank Ltd., 
    561 U.S. 247
    , 255 (2010)). But a presumption
    28
    is no more than that. To analyze issues of extraterritoriality in light of this
    presumption, we must apply a "two-step framework."
    Id. at 2101.
    At step one, we ask "whether the presumption . . . has been rebutted" by the
    statute in question, i.e., "whether the statute gives a clear, affirmative indication
    that it applies extraterritorially."
    Id. With respect
    to the case at bar, we neither
    have been pointed to, nor have we ourselves found, any such clear, affirmative
    statutory indication of extraterritoriality with respect to the statute at issue here.
    We therefore turn to step two of the inquiry to "determine whether the case
    involves a domestic application of the statute."
    Id. We begin
    this process by
    "looking to the statute's 'focus.'"
    Id. "The focus
    of a statute is 'the object of its
    solicitude,' which can include the conduct it 'seeks to regulate,' as well as the
    parties and interests it 'seeks to protect' or vindicate." WesternGeco LLC v. ION
    Geophysical Corp., 
    138 S. Ct. 2129
    , 2137 (2018) (brackets omitted) (quoting 
    Morrison, 561 U.S. at 267
    ). "'If the conduct [at issue] relevant to the statute's focus occurred
    in the United States, then the case involves a permissible domestic application' of
    the statute, 'even if other conduct occurred abroad.' . . . But if the relevant conduct
    occurred in another country, 'then the case involves an impermissible
    29
    extraterritorial application regardless of any other conduct that occurred in U.S.
    territory.'"
    Id. (internal citation
    omitted) (quoting RJR 
    Nabisco, 136 S. Ct. at 2101
    ).
    Appellants were convicted of conspiracy to commit honest services wire
    fraud, not the substantive offense of wire fraud itself. A conviction for honest
    services wire fraud conspiracy arises from the interaction of three statutes: wire
    fraud, under 18 U.S.C. § 1343, augmented by the honest services fraud statute, 18
    U.S.C. § 1346, and the wire fraud conspiracy statute, 18 U.S.C. § 1349. The relevant
    portions of those statutes provide in full:
    Whoever, having devised or intending to devise any scheme or
    artifice to defraud, or for obtaining money or property by means of
    false or fraudulent pretenses, representations, or promises, transmits
    or causes to be transmitted by means of wire, radio, or television
    communication in interstate or foreign commerce, any writings, signs,
    signals, pictures, or sounds for the purpose of executing such scheme or
    artifice, shall be fined under this title or imprisoned not more than 20
    years, or both.
    18 U.S.C. § 1343 (emphases added).
    For the purposes of this chapter [in particular, for present purposes,
    § 1343], the term “scheme or artifice to defraud” includes a scheme or
    artifice to deprive another of the intangible right of honest services.
    18 U.S.C. § 1346.
    Any person who attempts or conspires to commit any offense under
    this chapter shall be subject to the same penalties as those prescribed
    30
    for the offense, the commission of which was the object of the attempt
    or conspiracy.
    18 U.S.C. § 1349.
    "'[G]enerally, the extraterritorial reach of an ancillary offense [such as] . . .
    conspiracy is coterminous with that of the underlying criminal statute.'" United
    States v. Hoskins, 
    902 F.3d 69
    , 96 (2d Cir. 2018) (quoting United States v. Ali, 
    718 F.3d 929
    , 939 (D.C. Cir. 2013)). Neither the appellants nor the government dispute that
    the statute underlying the appellants' honest services wire fraud conspiracy
    convictions is the wire fraud statute, 18 U.S.C. § 1343. For the step-two analysis,
    therefore, we must determine the focus of § 1343.
    It is here that the parties join issue. In simplest terms, the appellants contend
    that § 1343's focus is a "scheme . . . to defraud" and that their scheme was
    principally foreign, while the government contends that the statute's focus is the
    "use of the wires" within, from, or to the United States "in furtherance of a scheme
    to defraud."
    After briefing in this case was complete, we answered this question, albeit
    in the context of civil RICO rather than criminal wire fraud. In Bascuñán v. Elsaca,
    
    927 F.3d 108
    (2d Cir. 2019), we made clear that the conduct regulated by § 1343 –
    that is, the statute's "focus" – was "not merely a 'scheme to defraud,' but more
    31
    precisely the use of the . . . wires in furtherance of a scheme to defraud."
    Id. at 122
    (emphasis in original). We also explained, however, that in order for incidental
    domestic wire transmissions not to haul essentially foreign allegedly fraudulent
    behavior into American courts, "the use of the . . . wires must be essential, rather
    than merely incidental, to the scheme to defraud."
    Id. This ensures
    that the
    domestic tail not wag, as it were, the foreign dog.
    After this Court decided Bascuñán, the appellants filed a Rule 28(j) 16 letter
    seeking to distinguish that case from this one. They contended that whatever the
    general rule might be, in cases such as this one involving convictions for honest
    services wire fraud, "the statute's focus for [the] extraterritoriality analysis" is not
    the use of the wires but rather the "bad-faith breach of a fiduciary duty owed to
    the scheme's victim." Appellants' Rule 28(j) Letter, October 18, 2019, at 1.
    We disagree. The argument mischaracterizes the nature of honest services
    wire fraud. It is not something different from wire fraud; it is a type of wire fraud
    that is explicitly prohibited by that statute. The statute includes a provision
    specific to honest services wire fraud not because it is in some essential aspect
    16 Fed. R. Civ. P. 28(j) provides in relevant part: "If pertinent and significant
    authorities come to a party's attention after the party's brief has been filed—or after
    oral argument but before decision—a party may promptly [so] advise the circuit
    clerk by letter, with a copy to all other parties, setting forth the citations."
    32
    different from other wire fraud, but to clarify the application of the law of wire
    fraud to honest services fraud.
    Federal courts began to recognize this theory of fraud based on private
    employer-employee relationships in the 1940s. See Skilling v. United States, 
    561 U.S. 358
    , 400 (2010). "In perhaps the earliest application of the theory,"
    id. at 401,
    a
    district court in Massachusetts explained:
    When one tampers with th[e] [employer-employee relationship] for the
    purpose of causing the employee to breach his duty [to his employer]
    he in effect is defrauding the employer of a lawful right. The actual
    deception that is practised [sic] is in the continued representation of the
    employee to the employer that he is honest and loyal to the employer's
    interests.
    United States v. Procter & Gamble Co., 
    47 F. Supp. 676
    , 678 (D. Mass. 1942).
    Thereafter, "'an increasing number of courts' recognized that 'a recreant
    employee' . . . . 'could be prosecuted . . . if he breached his allegiance to his
    employer by accepting bribes or kickbacks in the course of his employment.'"
    
    Skilling, 561 U.S. at 401
    (brackets omitted) (quoting United States v. McNeive, 
    536 F.2d 1245
    , 1249 (8th Cir. 1976)). "[B]y 1982, all Courts of Appeals had embraced
    the honest services theory of fraud. . . . "
    Id. But then,
    "[i]n 1987," the Supreme Court "stopped the development of the
    intangible-rights doctrine in its tracks" with its decision in McNally v. United States,
    33
    
    483 U.S. 350
    (1987).
    Id. In McNally,
    the Court read the mail fraud statute (generally
    parallel to the wire fraud statute for present purposes) "as limited in scope to the
    protection of property rights." 
    McNally, 483 U.S. at 360
    . "If Congress desires to go
    further," the Court said, "it must speak more clearly."
    Id. Congress did
    as it was bade; the following year, it enacted 18 U.S.C. § 1346,
    a new "honest services statute" that provided: "For the purposes of th[e] chapter
    [of the United States Code that prohibits, inter alia, mail fraud, § 1341, and wire
    fraud, § 1343], the term 'scheme or artifice to defraud' includes a scheme or artifice
    to deprive another of the intangible right of honest services.'" 
    Skilling, 460 U.S. at 402
    (brackets in original; emphasis added) (quoting 18 U.S.C. § 1346).
    On this point, therefore, the law is clear: Honest services wire fraud is
    "include[d]" as a type of wire fraud prohibited under § 1343. 18 U.S.C. § 1346. The
    fact that the appellants were convicted of honest services wire fraud thus has no
    bearing on our extraterritoriality analysis; it is § 1343, not § 1346, whose "focus" we
    must "look to" in step two of the analysis. And for our answer we need look no
    further than Bascuñán and the words of the statute itself: The focus of § 1343 is "the
    use of the . . . wires in furtherance of a scheme to defraud." 
    Bascuñán, 927 F.3d at 122
    (emphasis in original).
    34
    We therefore must do here as RJR Nabisco requires: determine whether "the
    conduct relevant to the statute's focus" – that is, the use of the wires in furtherance
    of the schemes to defraud – "occurred in the United States." RJR 
    Nabisco, 136 S. Ct. at 2101
    . To affirm, we must also conclude that the "use of the . . . wires" was
    "essential, rather than merely incidental, to [the appellants'] scheme to defraud."
    
    Bascuñán, 927 F.3d at 122
    .
    As to the first question, at trial, the government presented ample evidence
    that the appellants had used American wire facilities and financial institutions to
    carry out their fraudulent schemes. The government established, inter alia, that
    Marin frequently received bribe payments from the sports media and marketing
    companies in his "Firelli International Limited" account with Morgan Stanley bank
    in New York. Marin also used a debit card connected with the "Firelli" account to
    make purchases of, among other things, $50,000 of jewelry, and $10,000 of clothing
    at stores in the United States. The government similarly established that Napout
    was often bribed with American banknotes from U.S. bank accounts that had been
    wired to a cambista (money changer) in Argentina, delivered to Full Play's safety
    deposit box, and then given to Napout by hand. Napout was also bribed with
    luxury items including, for example, concert tickets and the use of a vacation
    35
    house, which, wherever located, were paid for with money wired from a U.S. bank
    account. These connections between the events in the United States and the wire
    transactions at issue are roughly parallel to those alleged in the Bascuñán civil
    complaint that survived a motion to dismiss. See 
    Bascuñán, 927 F.3d at 112
    –15.
    The same evidence provides the answer to the question as to the centrality
    of the domestic use of wire transfers to the alleged foreign scheme. At the time of
    their arrests in 2015, the appellants had each received approximately $3.3 million
    in bribes; at least $2.4 million of Marin's payments had been sent to his New York
    bank account, Test. of IRS Agent Berryman Trial Tr. at 3483–86, App. at 596–601,
    while $2.5 million of Napout's $3.3 million had been paid in cash in U.S. dollars
    generated by wire transfers originating in the United States, Peña Ledger, Gov't
    App. at 400. The use of wires in the United States therefore was integral to the
    transmission of the bribes in issue to the appellants. It was in return for the bribes
    that Marin and Napout (and their co-conspirators) gave the sports media and
    marketing companies exclusive rights to various CONMEBOL tournaments under
    their control. The transmission, then, was central to the alleged schemes. And
    U.S. wires provided a — or the — key means of paying those bribes. In other
    36
    words, in the relatively straightforward quid pro quo transactions underlying these
    schemes, the quid was provided through the use of U.S. wires.
    B.     Vagueness
    The appellants next contend that § 1346 is unconstitutionally vague as
    applied to them.
    "The void-for-vagueness doctrine requires that a penal statute define the
    criminal offense with sufficient definiteness that ordinary people can understand
    what conduct is prohibited and in a manner that does not encourage arbitrary and
    discriminatory enforcement." United States v. Halloran, 
    821 F.3d 321
    , 337–38 (2d
    Cir. 2016) (quoting United States v. Rosen, 
    716 F.3d 691
    , 699 (2d Cir. 2013) (internal
    quotation marks omitted)). "The doctrine addresses concerns about (1) fair notice
    and (2) arbitrary and discriminatory prosecutions."
    Id. at 338
    (quoting 
    Rosen, 716 F.3d at 699
    (internal quotation marks omitted)). "Under the 'fair notice' prong, a
    court must determine 'whether the statute, either standing alone or as construed,
    made it reasonably clear at the relevant time that the defendant's conduct was
    criminal.’" Id. (quoting 
    Rosen, 716 F.3d at 699
    (internal quotation marks omitted)).
    Recognizing that a "violation of a fiduciary duty," is an "element of honest
    services fraud,"
    Id. at 337,
    the appellants contend, in essence, that § 1346 did not
    37
    provide them with "fair notice" that the fiduciary duty they, as foreign employees,
    owed to their foreign employers, FIFA and CONMEBOL, could qualify as a "source
    of the fiduciary obligation," 
    Skilling, 561 U.S. at 417
    (Scalia, J., concurring in the
    judgment), whose breach, if committed by a fraudulent scheme using American
    wires, would constitute honest services wire fraud.
    Before reaching the merits of the appellants' argument, we must consider
    what standard of review to apply. The parties dispute this point. The appellants
    allege that Napout twice raised this vagueness challenge to the district court, and
    thus urge us to review their argument de novo. The government asserts to the
    contrary that Napout did not raise his vagueness challenge in the district court,
    and contends that we must review the argument for plain error. We agree with
    the government. 17
    Napout alleges that he first raised the vagueness argument in the
    memorandum of law he filed in support of his pretrial "motion to dismiss all
    charges for lack of extraterritorial jurisdiction." App. at 158–69. In the relevant
    portion of that memorandum, Napout argued that "the allegations against [him]
    fall squarely within the presumption against extraterritoriality and thus, fail to
    17The parties appear to agree that Marin did not raise the vagueness issue before
    the district court.
    38
    satisfy the first step in the RJR Nabisco analysis." App. at 160. This argument was
    not a vagueness challenge; it was an argument against the extraterritorial
    application of the wire fraud statute.
    Second, Napout asserts that he raised a vagueness challenge in the
    memorandum he filed in support of his motion for acquittal pursuant to Federal
    Rule of Criminal Procedure 29(a). It is true, that in that memorandum, Napout
    quoted several judicial opinions, including Justice Scalia's concurrence in Skilling,
    that discuss the issue of vagueness as it pertains to the source of the fiduciary
    obligation under § 1346. For example, the memorandum notes that in United States
    v. Smith, 
    985 F. Supp. 2d 547
    (S.D.N.Y. 2014), a judge of the Southern District of
    New York remarked on the "difficulty" that "inheres in any attempt to describe in
    the abstract the 'fiduciary duty' the violation of which all honest services-wire-
    fraud prosecutions might require."
    Id. at 592.
          Yet, the memorandum raised
    nothing that can be understood as a vagueness challenge to Napout's conviction.
    Instead, it made only one argument: that because the bribes Napout received were
    "euphemistically" considered to be a permissible form of "personal payments" in
    the South American countries in which he lived and worked, his acceptance of
    such bribes did not "result[] in any identifiable harm to FIFA," and thus did not
    39
    "deprive FIFA of [Napout's] honest services." App. at 651–52. In other words, as
    the memorandum states in a footnote, the district court should have "allow[ed]
    [Napout] to prove to the jury that commercial bribery is not a crime in either
    Argentina or Paraguay, such that a reasonable person in [his] position would not
    believe that a technical violation of [FIFA's] codes constituted a breach of any duty
    owed to the organization." App. at 652 n.1. And while, in another footnote, the
    memorandum points out that “due process concerns may well arise if, for example
    ‘a situation arose in which a defendant was charged with honest-services wire
    fraud, and the fiduciary duty that the defendant allegedly breached existed under
    federal law, but not under state law, or vice versa,’” App. at 656 n.6 (quoting 
    Smith, 985 F. Supp. 2d at 598
    ), the memorandum does not argue that such concerns exist
    in this case.
    Thus, while these statements may use language similar to what might have
    been employed in a vagueness challenge — that is, language concerning what a
    "reasonable person" would have "believed" about the statute — they can only be
    understood, we think, as part of the memorandum's sole argument that Napout's
    acquittal was mandated by the government's failure to show that his receiving
    bribes breached his fiduciary duty to FIFA. Because this argument is not a
    40
    vagueness challenge, and because it is the only argument Napout made in
    connection with his Rule 29(a) motion, we conclude that Napout did not raise his
    vagueness challenge in his Rule 29(a) motion, that he therefore did not raise the
    challenge before the district court, and that we therefore must review his argument
    on appeal for plain error. 18
    Under plain error review, an appellant must demonstrate that "(1) there is
    an error; (2) the error is clear or obvious, rather than subject to reasonable dispute;
    (3) the error affected the appellant's substantial rights, which in the ordinary case
    means it affected the outcome of the district court proceedings; and (4) the error
    seriously affects the fairness, integrity or public reputation of judicial
    proceedings." United States v. Marcus, 
    560 U.S. 258
    , 262 (2010) (brackets and
    internal quotation marks omitted). "[R]eversal for plain error should 'be used
    sparingly, solely in those circumstances in which a miscarriage of justice would

    support that a party provides for a proposition presented below.” Eastman Kodak
    Co. v. STWB, Inc.,

    , 221 (2d Cir. 2006) (citing Yee v. City of Escondido,
    
    503 U.S. 519
    , 534 (1992) ('Once a federal claim is properly presented, a party can
    make any argument in support of that claim; parties are not limited to the precise
    arguments they made below.')). That is not, however, what they attempt to do
    here.
    41
    otherwise result.'" United States v. Villafuerte, 
    502 F.3d 204
    , 209 (2d Cir. 2007)
    (quoting United States v. Frady, 
    456 U.S. 152
    , 163 n.14 (1982)).
    Our decision here is determined by application of plain error's second
    requirement: that "[f]or an error to be plain, it must, at a minimum, be clear under
    current law," which means that "[w]e typically will not find such error where the
    operative legal question is unsettled, including where there is no binding
    precedent from the Supreme Court or this Court." United States v. Whab, 
    355 F.3d 155
    , 158 (2d Cir. 2004) (internal quotation marks omitted).
    There are undoubtedly "lingering ambiguities in § 1346," 
    Halloran, 821 F.3d at 337
    (discussing 
    Skilling, 561 U.S. at 417
    (Scalia, J., concurring in the judgment)),
    including questions as to what may serve as "the source of the fiduciary obligation"
    that can sustain a conviction under the statute. 
    Skilling, 561 U.S. at 417
    (Scalia, J.,
    concurring in the judgment) (emphasis in original). As we have noted, the statute
    "provides no textual guidance about the duties whose violation will amount to a
    deprivation of 'honest services,'" United States v. Coppola, 
    671 F.3d 220
    , 235 (2d Cir.
    2012), an issue that caused Justice Scalia in Skilling — and courts since — to wonder
    whether, to be actionable under § 1346, a fiduciary duty "must" arise from "positive
    state or federal law," or whether "merely general principles, such as the obligations
    42
    of loyalty and fidelity that inhere in the employment relationship" can suffice,
    
    Skilling, 561 U.S. at 417
    (Scalia, J., concurring in the judgment).    Taking those
    concerns and running with them, the appellants argue that even assuming that
    they owed a fiduciary duty to FIFA and CONMEBOL under the organizations'
    codes of ethics, any such duty – that is, a fiduciary duty a foreign employee owes
    to his foreign employer through the nature of their private employment
    relationship rather than a duty arising from specific law – cannot form the basis of
    an honest services conviction.
    Although not necessarily dispositive of the appellants' argument, our
    decision in United States v. Rybicki, 
    354 F.3d 124
    (2d Cir. 2003) (en banc), provides
    possible guidance. There, three attorneys who had been convicted of honest
    services wire fraud raised an as-applied vagueness challenge to § 1346 that focused
    on the limits of the conduct the statute may penalize; they alleged that the statute
    did not clearly prohibit their having "arranged for secret gratuities to be paid to
    claims adjusters employed by insurance companies against whom [their] clients
    asserted claims."
    Id. at 127.
    Although we focused primarily on the issue of what
    conduct falls within the scope of § 1346, we also addressed the question of from
    what source a fiduciary duty underlying guilt under § 1346 may arise. We
    43
    concluded that the theory of honest services wire fraud applies to "an officer or
    employee of a private entity" or "a person in a relationship that gives rise to a duty
    of loyalty comparable to that owed by employees to employers. . . ."
    Id. at 141-42;
    see also
    id. at 142,
    n.17.
    Other courts have gone further. In United States v. Milovanovic, 
    678 F.3d 713
    (9th Cir. 2012) (en banc), a case closer to the one at bar than Rybicki, an en banc
    Ninth Circuit, citing Rybicki, held "that a fiduciary duty for the purposes of the
    Mail Fraud Statute [again parallel for present purposes to § 1346 applicable to wire
    fraud] is not limited to a formal 'fiduciary' relationship well-known in the law, but
    also extends to a trusting relationship in which one party acts for the benefit of
    another and induces the trusting party to relax the care and vigilance which it
    would ordinarily exercise."
    Id. at 724.
    The appellants have pointed us to no authority directly supporting their
    position, nor have we found any ourselves, other than two pre-Skilling district
    court cases which they acknowledge are "not . . . directly analogous to this case,"
    Napout Br. at 42, that suggests that the duty they owed to FIFA and CONMEBOL
    falls beyond the scope of § 1346. Rather, whether a foreign employee's duty to his
    foreign employer qualifies as an actionable element under § 1346 is a question that
    44
    remains unsettled, at best. Thus, because it is not "clear under current law," 
    Whab, 355 F.3d at 158
    , that § 1346 is unconstitutionally vague as applied to the appellants,
    the district court did not commit plain error in concluding that it is not. 19
    C.     Sufficiency of the Evidence
    Next, the appellants raise an argument similar to the one made by Napout
    in his Rule 29(a) motion in the district court: They challenge the sufficiency of the
    evidence against them by alleging that the government "failed to adduce any
    evidence that" they owed a fiduciary duty to their employer (both CONMEBOL
    and FIFA) under the laws of Paraguay, the country where CONMEBOL is
    headquartered. Napout Br. at 5.
    Although we review a challenge to the sufficiency of the evidence de novo,
    United States v. Khalil, 
    857 F.3d 137
    , 139 (2d Cir. 2017), the challenger "bears a heavy
    burden," United States v. Coplan, 
    703 F.3d 46
    , 62 (2d Cir. 2012) (quoting United States
    v. Heras, 
    609 F.3d 101
    , 105 (2d Cir. 2010)), and our review is "exceedingly
    deferential," id (quoting United States v. Hassan, 
    578 F.3d 108
    , 126 (2d Cir. 2008)).
    19The filing of the concurrence should not be construed as disagreement by the
    other panel members with the analysis contained therein, but rather reflects their
    view that the issue need not be addressed under the plain error review in which
    we engage.
    45
    The appellants' sufficiency argument miscasts the fiduciary duty they were
    convicted of breaching. The appellants were not prosecuted for breaching a
    fiduciary duty created by Paraguayan law— or Brazilian, Swiss or U.S. law, for
    that matter. The government alleged, and the jury found, that the appellants'
    conduct of accepting bribes had violated the fiduciary duty they owed to FIFA and
    CONMEBOL under the organizations' codes of ethics.              In other words, the
    "fiduciary duty" — the legal obligation to provide "honest services" — that the
    appellants owed to their employer, the breach of which, accomplished by wire
    fraud, was the crime for which they were convicted, arose from their acceding to
    FIFA and CONMEBOL's rules, not the provision of the law of any state or country.
    And the government's evidence was easily sufficient to prove that FIFA and
    CONMEBOL's respective codes of ethics expressly provided that persons bound
    by those codes, including, inter alia, that "all" soccer "officials," such as Marin and
    Napout, had "a fiduciary duty to FIFA [and] the confederations [such as
    CONMEBOL]," and were required to "act with absolute loyalty" to them. App. at
    1056, 1105. Accordingly, "the 'existence of a fiduciary relationship' between [the]
    employee[s] and [their] employer [was] 'beyond dispute.'" United States v. Nouri,
    
    711 F.3d 129
    , 137 n.1 (2d Cir. 2013) (quoting 
    Skilling, 561 U.S. at 406
    –07 n.41).
    46
    D.     Evidentiary Decisions
    1.     Foreign Law Evidence
    The appellants next take issue with two of the district court's evidentiary
    decisions concerning foreign law.
    First, they contend that the court violated Federal Rule of Evidence 403 by
    precluding them from introducing evidence or questioning witnesses about
    whether commercial bribery is lawful in Brazil and Paraguay.
    "[S]o long as the district court has conscientiously balanced the proffered
    evidence's probative value with the risk for prejudice, its conclusion [to preclude
    evidence pursuant to Federal Rule of Evidence 403] will be disturbed only if it is
    arbitrary or irrational." United States v. Awadallah, 
    436 F.3d 125
    , 131 (2d Cir. 2006).
    Thus, even if erroneous, a court's decision to preclude evidence under Rule 403
    warrants reversal only if it "had a substantial and injurious effect or influence on
    the jury's verdict." United States v. Spoor, 
    904 F.3d 141
    , 153 (2d Cir. 2018) (internal
    quotation marks omitted).
    In particular, the appellants argue — as they did to the district court — that
    they should have been permitted to introduce evidence that commercial bribery
    was legal in their home countries because that fact, in their view, reveals that they
    47
    lacked the fraudulent intent (or bad faith) necessary to have committed honest
    services wire fraud.
    The district court considered this evidence and conducted the
    "conscientious balancing" called for by Awadallah. At the outset of its analysis, the
    court noted that whether the appellants had acted in bad faith turned not on
    whether they had acted with the intent to violate the laws of their home countries,
    but whether they had understood that their accepting bribes violated their duties
    to FIFA and CONMEBOL under the organizations' codes of ethics. Thus, evidence
    that commercial bribery was permitted under the laws of Brazil or Paraguay
    would be relevant to the question of the appellants' intent only if the jury could
    infer that: (1) the laws of the appellants' home countries permitted commercial
    bribery and the appellants "knew or believed" that to be so; and (2) the appellants
    "believed that their duties to FIFA and [CONMEBOL] were identical to their
    obligations under th[ose] foreign law[s]." United States v. Webb et al., No.15-cr-
    00252 (E.D.N.Y. Dec. 12, 2017), Mem. & Order Regarding Motion in Limine, ECF
    No. 853 at 24, Special App. at 57. Because the appellants had not "articulated any
    reason to believe, let alone proffered any evidence, that they construed their duties
    to FIFA or [CONMEBOL] based on their understanding of their own countries'
    48
    criminal laws," the court determined that the second necessary inference was "so
    attenuated that it border[ed] on speculation" and thus that the evidence of foreign
    law proffered by the appellants carried "extremely low probative value."
    Id. at 25,
    Special App. at 58.
    The district court concluded, moreover, that introduction of the foreign law
    evidence by the defendants presented "an obvious risk of jury nullification" in light
    of the "substantial risk that the jury would improperly acquit [the appellants] if it
    believed that commercial bribery did not violate the laws of [their] home
    countries."
    Id. In other
    words, allowing the jury to focus on the legality of the
    appellants' conduct in Brazil or Paraguay would risk the jury's ignoring the
    question it needed to answer to determine their guilt or innocence: whether their
    accepting bribes had violated FIFA and CONMEBOL's codes of ethics, and thus
    had deprived those organizations of their honest services in violation of U.S. law.
    In sum, the district court decided, "the risk of prejudice and juror confusion
    substantially outweigh[ed] any probative value there may be to" allowing the
    appellants to introduce this foreign law evidence.
    Id. at 26,
    Special App. at 59.
    The district court's conclusion in this regard was hardly "arbitrary or
    irrational." 
    Awadallah, 436 F.3d at 131
    . Indeed, particularly in light of the at-
    49
    best-tangential nature of the relationship between the law of commercial bribery
    in Brazil and Paraguay and the U.S. law of conspiracy to commit wire fraud for
    the alleged violation of which the appellants were on trial, we do not think that
    the district court erred.
    The appellants offer two other arguments that this conclusion was "arbitrary
    or irrational." First, they attempt to draw a parallel between their proffered foreign
    law evidence and the testimony of Stephanie Maennl, a government witness and
    FIFA lawyer whom the district court allowed to testify about FIFA's code of ethics.
    Marin Br. at 14–16. They argue that the relevance of Maennl's testimony, like the
    relevance of their foreign law evidence, required the jury to make a series of
    unwarranted inferential leaps. Not so: Maennl's testimony required the jury to
    draw only a single – and indeed modest –inference, that the appellants were aware
    of their obligations under the code of ethics she was describing, instead of the two
    inferences that were required to make the appellants' evidence probative. The
    appellants point to United States v. Brandt, 
    196 F.2d 653
    (2d Cir. 1952), for the
    proposition that in a prosecution for wire fraud, "since [good faith, or the lack
    thereof] may be only inferentially proven, . . . no events or actions which bear even
    remotely on its probability should be withdrawn from the jury unless the
    50
    tangential and confusing elements interjected by such evidence clearly outweigh
    any relevancy it might have."
    Id. at 657.
    That instruction, however, calls for
    precisely the analysis that the district court performed here: As the court in
    substance concluded, whatever minor probative value the appellants' foreign law
    evidence may have had, it was "substantially outweigh[ed]" by the risk that its
    introduction would cause the jury to be confused or inclined to vote not guilty
    simply because the appellants' conduct was not illegal in their home countries.
    United States v. Webb et al., No. 15-cr-00252 (E.D.N.Y. Dec. 12, 2017), Mem. & Order
    Regarding Motion in Limine, ECF No. 853 at 26, Special App. at 59.
    For their second argument, Marin Br. at 26–29, the appellants attack what
    the district court described as a "caveat" to its ruling.
    Id. The court
    acknowledged
    that its justification for excluding the foreign-law evidence — i.e., that it would
    require the jury to make two significant inferential steps — did not justify
    preventing the appellants from testifying that they themselves "relied on [their]
    belief or understanding of [their] own country's laws to determine [their]
    obligations to FIFA or [CONMEBOL]."
    Id. That testimony,
    the court concluded,
    would "bridge the gap between the [appellants'] belief[s] about foreign law . . . and
    [their] belief[s] about [their] duties to FIFA or [CONMEBOL]" and thus "would not
    51
    suffer from the same infirmity of attenuation . . . that render[ed] the other
    proffered evidence . . . inadmissible."
    Id. at 26–27,
    Special App. at 59–60.
    The appellants insist that this ruling forced them "to choose, without good
    reason, between [their] Fifth Amendment right not to testify and [their] Sixth
    Amendment right to present a complete defense." Napout Br. at 56.
    "The criminal process," however, "is replete with situations requiring the
    making of difficult judgments as to which course to follow." Corbitt v. New Jersey,
    
    439 U.S. 212
    , 218 n.8 (1978) (internal quotation marks omitted). Therefore, even
    when a defendant has a "right . . . of constitutional dimension . . . to follow
    whichever course he chooses, the Constitution does not by that token always
    forbid requiring him to choose."
    Id. (internal quotation
    marks omitted). Under
    these circumstances, because the foreign law evidence was probative only as it
    pertained to the appellants' understanding of their obligations to FIFA and
    CONMEBOL, and because only the appellants themselves could testify as to that
    understanding, the district court's ruling, although it forced the appellants to make
    a potentially difficult choice, did not run afoul of the Constitution.
    2.    Expert Testimony
    52
    The appellants also argue that the district court erred by allowing the
    government's expert witness, Professor Stefan Szymanski, to testify about the
    economic impact that officials accepting bribes would have on soccer
    organizations such as FIFA and CONMEBOL. This testimony, they contend, was
    unreliable and inadmissible because Szymanski had not performed "any . . .
    empirical study of the evidence in this case." Marin Br. at 42.
    "The admissibility of expert testimony in the federal courts is governed
    principally by Rule 702 of the Federal Rules of Evidence." Nimely v. City of New
    York, 
    414 F.3d 381
    , 395 (2d Cir. 2005). We review a district court's decision to admit
    expert testimony under Federal Rule of Evidence 702 for abuse of discretion.
    Id. at 393.
    Rule 702 allows a witness to testify as an expert if his or her "specialized
    knowledge will help the trier of fact to understand the evidence or to determine a
    fact in issue"; the "testimony is based on sufficient facts or data" and "is the product
    of reliable principles and methods"; and the witness "has reliably applied the
    principles and methods to the facts of the case." Fed. R. Evid. 702. "It is a well-
    accepted principle that Rule 702 embodies a liberal standard of admissibility for
    expert opinions[.]" 
    Nimely, 414 F.3d at 395
    . In considering whether to admit expert
    53
    testimony under Rule 702, a district court serves a "gatekeeping role" by "ensuring
    that an expert's testimony both rests on a reliable foundation and is relevant to the
    task at hand." Daubert v. Merrell Dow Pharms., Inc., 
    509 U.S. 579
    , 597 (1993).
    Szymanski, a professor of sports management at the University of Michigan,
    conducts research on the economics and business of sports. Before trial, the
    appellants moved to preclude Szymanski from testifying on the grounds that he
    had not performed "empirical analysis of actual data relating to FIFA." App. at
    328. In denying the motion, the district court determined that any empirical basis,
    or lack thereof, would go to the weight of Szymanksi's testimony, not its
    admissibility.
    On cross-examination, defense counsel asked Syzmanski to confirm that he
    had not "actually review[ed] any empirical data . . . of the actual prices or revenues
    that were generated by the media or marketing contracts involved in this case."
    App. at 393–400. Syzmanski agreed, stating that he had not analyzed the "specific
    financial information . . . of CONMEBOL regarding the sale of contracts" because
    it "was not available" and he "did not have access to it."
    Id. at 395.
    On appeal, the appellants essentially raise the same argument they made to
    the district court: that Szymanski's testimony, which was "not based on any actual
    54
    data or empirical analysis," was so unreliable as to be inadmissible. Marin Br. at
    44. Moreover, they allege that allowing Syzmanski to testify ran afoul of United
    States v. Tin Yat Chin, 
    371 F.3d 31
    , 40–41 (2d Cir. 2004), where we upheld a district
    court's decision to exclude expert testimony it viewed as insufficiently supported
    by data or facts. Tin Yat Chin, however, does not stand for the principle that a
    court must always exclude expert testimony that is less than perfectly supported
    by data. See
    id. at 41
    (declining to impose a standard that requires exclusion of
    certain expert testimony). It serves only to confirm that a district court has "broad
    discretion" to decide "how to determine reliability" of proposed expert testimony
    and to reach an "ultimate conclusion" with respect to admissibility. Restivo v.
    Hessemann, 
    846 F.3d 547
    , 575 (2d Cir. 2017) (quoting Amorgianos v. Nat'l R.R.
    Passenger Corp., 
    303 F.3d 256
    , 265 (2d Cir. 2002)).
    We have recently observed along these lines that while a "trial judge should
    exclude expert testimony if it is speculative or conjectural or based on assumptions
    that are so unrealistic and contradictory as to suggest bad faith or to be in essence
    an apples and oranges comparison . . . other contentions that [an expert's]
    assumptions are unfounded go to the weight, not the admissibility, of the
    testimony."   
    Restivo, 846 F.3d at 577
    (internal quotation marks and citation
    55
    omitted). In the circumstances of this case, therefore, we cannot conclude that the
    district court abused its discretion by deciding that Szymanski's lack of familiarity
    with the facts underlying this case went to the weight and not the admissibility of
    his testimony.
    E.     Partial Sequestration of Jury
    Finally, the appellants argue that the district court deprived them of their
    Fifth and Sixth Amendment rights to a fair and impartial jury by granting the
    government's motion for a partially anonymous and semi-sequestered jury.
    "If a district court has taken reasonable precautions to protect a defendant's
    fundamental rights, we review its decision to empanel an anonymous jury for
    abuse of discretion." United States v. Kadir, 
    718 F.3d 115
    , 120 (2d Cir. 2013) (citing
    United States v. Thai, 
    29 F.3d 785
    , 801 (2d Cir. 1994)). A district court minimizes
    the prejudicial effects of an anonymous jury on the defendant by "giving the jurors
    'a plausible and nonprejudicial reason for not disclosing their identities'" and by
    conducting a "voir dire designed to uncover bias."
    Id. (quoting Thai,
    29 F.3d at 801).
    "[W]hen genuinely called for and when properly used, anonymous juries do not
    infringe a defendant's constitutional rights." United States v. Pica, 
    692 F.3d 79
    , 88
    (2d Cir. 2012) (quoting 
    Thai, 29 F.3d at 800
    ). After "taking reasonable precautions
    56
    to minimize any prejudicial effects on the defendant and to ensure that his
    fundamental rights are protected," "[a] district court may order the empaneling of
    an anonymous jury 'upon . . . concluding that there is strong reason to believe the
    jury needs protection.'" 
    Kadir, 718 F.3d at 120
    (quoting 
    Pica, 692 F.3d at 88
    ).
    Most importantly, the district court protected the appellants’ fundamental
    rights by ensuring that the jury was not anonymous with respect to any of the
    parties. While the jurors' identities were kept from the public, the appellants and
    their counsel (and the government, too) were provided with the names of the
    prospective jurors during jury selection and were free to investigate any of them
    for potential bias.    Moreover, the court employed a jury questionnaire and
    permitted all parties to review the prospective jurors' answers and move to strike
    jurors for cause. Similarly, the court allowed the parties to conduct extensive voir
    dire before submitting their peremptory challenges. And the court instructed the
    empaneled jurors that the measures of partial sequestration (being transported to
    and from the courthouse by U.S. Marshals and being required to remain in the jury
    room or behind the courtroom during breaks) were "not unusual" and were "being
    taken to ensure [their] privacy and impartiality in light of the media and public
    attention this trial is likely to receive." App. at 378–79.
    57
    The district court's conclusion that there was strong reason for the jury to be
    kept anonymous and sequestered from the public fell well within its discretion.
    For one thing, as the appellants acknowledge, this case prompted a significant
    amount of media attention across the world, including reporting that revealed
    personal information about potential witnesses. In a sealed filing, the government
    also proffered evidence suggesting a possibility that jurors might face safety
    concerns if their names were revealed to the public, including evidence that
    potential witnesses in the case had already been subjected to severely intimidating
    behavior.
    The appellants do not challenge any of the evidence cited by the district
    court in this regard. Instead, they rely on two opinions from the Southern District
    of New York to argue that the district court's conclusion was incorrect as a matter
    of law.
    First, the appellants assert that a court's concern about media attention,
    "without more," is "insufficient to justify the impact on a defendant's trial that
    empaneling an anonymous jury may have." United States v. Mostafa, 
    7 F. Supp. 3d 334
    , 336 (S.D.N.Y. 2014) (citing United States v. Vario, 
    943 F.2d 236
    , 241 (2d Cir.
    1991)).   Even were Mostafa precedential for these purposes, however, it is
    58
    inapposite. The district court's decision here relied on legitimate considerations of
    juror safety in addition to its concerns about media attention that did not exist in
    that case.
    Second, the appellants argue that the government could not make a
    "satisfactory showing of a reasonable likelihood of juror intimidation," because
    "[t]here [was] no evidence that [the appellants] either participated in or directed
    efforts to . . . intimidate witnesses." United States v. Gambino, 
    818 F. Supp. 536
    , 540
    (S.D.N.Y. 1993). Our caselaw does not, however, require a court to find that a
    defendant personally intimidated or attempted to intimidate witnesses or others
    associated with the trial in order to empanel an anonymous jury. In United States
    v. Aulicino, 
    44 F.3d 1102
    (2d. Cir. 1995), for example, we concluded that the district
    court did not err in empaneling an anonymous jury based on "evidence of
    potential jury tampering by [the defendant's] coconspirators . . . even in the
    absence of evidence that [the defendant] in particular had sought to obstruct
    justice."
    Id. at 1117.
    In a more recent summary order, we affirmed the empaneling
    of an anonymous jury based on "threats made to cooperating witnesses by other
    participants in the" defendant's conspiracy. United States v. Vendetta, 
    83 F. App'x 394
    , 400 (2d Cir. 2003) (summary order), vacated on other grounds by Vondette v.
    59
    United States, 
    543 U.S. 1108
    (2005)). The court's finding, therefore, that the "threats
    and violence" faced by the potential witnesses "ha[d] a clear connection and [were]
    directed to preventing the investigation and/or prosecution of one of the crimes
    for which the defendants [were] on trial" adequately justified its decision to
    partially anonymize and sequester the jury. Sealed App. at 20.
    CONCLUSION
    For the reasons set forth above, we conclude that the appellants' convictions
    rest upon permissible domestic applications of the wire fraud statute, 18 U.S.C. §
    1343. In addition, we cannot conclude in light of case law binding on us that the
    district court committed plain error with respect to the issue of whether the honest
    services wire fraud statute, 18 U.S.C. § 1346, is unconstitutionally vague as applied
    to the appellants. We also conclude that the evidence presented at trial was
    sufficient to affirm the district court's judgment of conviction; and that the
    challenged evidentiary rulings of the district court were not error. We have
    considered the remainder of the appellants' arguments on appeal and conclude
    that they are without merit. We therefore AFFIRM the judgments of the district
    court.

    HALL, Circuit Judge, concurring:
    I fully concur with Judge Sack’s opinion. I write separately to
    add that even if the Defendants-Appellants had argued below that
    honest services wire-fraud is unconstitutionally vague because the
    statute, 18 U.S.C. § 1346, does not define the scope of the fiduciary duty
    required to prove the element of “honest services,” see Slip Op. at 38-
    45, I would affirm their convictions.
    As the opinion notes, “perhaps the earliest application” of an
    honest services fraud theory in a criminal case occurred in 1940, in
    United States v. Procter & Gamble Co., 
    47 F. Supp. 676
    (D. Mass. 1942).
    Slip Op. at 33 (quoting Skilling v. United States, 
    561 U.S. 358
    , 401 (2010)).
    In Procter & Gamble, the district court observed that “[t]he normal
    relationship of employer and employee implies that the employee will
    be loyal and honest in all his actions with or on behalf of his employer,
    and that he will not wrongfully divulge to others the confidential
    information, trade secrets, etc., belonging to his 
    employer.” 47 F. Supp. at 678
    . Although McNally v. United States, 
    483 U.S. 350
    (1987), limited the government’s ability to pursue honest services
    fraud cases, see Slip Op. at 34, the near immediate adoption of § 1346
    after that decision has led this court to look back at pre-McNally case
    law to determine the scope of that section. See, e.g., United States v.
    Rybicki, 
    354 F.3d 124
    , 144-45 (2d Cir. 2003) (en banc). Prior to McNally,
    courts considered the combination of two factors—(a) the fiduciary
    duty inherent in an employer-employee relationship and (b) the
    acceptance of bribes or kickbacks in breach of that duty—to be
    sufficient to convict an individual of mail fraud. See 
    Skilling, 561 U.S. at 401
    (citing United States v. McNeive, 
    536 F.2d 1245
    , 1249 (8th Cir.
    1976)). Thus, were we deciding the issue here, I would hold that § 1346
    encompasses the duty that existed between the Defendants-
    Appellants and their employers, FIFA and CONMEBOL.
    Although there has been some discussion of whether the source
    of the fiduciary duty required to be proven in an honest services
    2
    wire-fraud prosecution must arise from “positive state or federal law,”
    Slip Op. at 43 (quoting 
    Skilling, 561 U.S. at 417
    (Scalia, J., concurring)),
    there was no such requirement in our pre-McNally understanding of
    the mail fraud statute. In United States v. Von Barta, 
    635 F.2d 999
    (2d
    Cir. 1980), affirming a conviction of mail fraud and discussing the
    development of honest services fraud, we noted explicitly:
    Our discussion is not to be construed as holding that an
    employee’s duty to disclose material information to his
    employer must be imposed by state or federal statute.
    Indeed, the employment relationship, by itself, may
    oblige an employee not to conceal, and in fact to reveal,
    information he has reason to believe is material to the
    conduct of his employer’s business.
    Von 
    Barta, 635 F.2d at 1007
    ; see also United States v. Bronston, 
    658 F.2d 920
    , 926 (2d Cir. 1981). This understanding of the fiduciary duty
    requirement, moreover, was not limited to our Circuit. See United
    States v. Bush, 
    522 F.2d 641
    , 651-52 (7th Cir. 1975) (holding that a
    defendant’s “duty to disclose need not be based upon the existence of
    some statute prescribing such a duty”); United States v. Brown, 
    540 F.2d 3
    364, 374-75 (8th Cir. 1976) (same); see also United States v. Bohonus, 
    628 F.2d 1167
    , 1172 (9th Cir. 1980) (concluding “that depriving an
    employer of one’s honest services and of its right to have its business
    conducted honestly can constitute a ‘scheme to defraud’”). In sum,
    when the government proves that a defendant-employee has
    concealed information that is material to the conduct of his employer’s
    business, it has proven the defendant has breached a fiduciary duty to
    his employer and has thus deprived the employer of his honest
    services. See also 
    Rybicki, 354 F.3d at 141-42
    , 142 n.17; United States v.
    Milovanovic, 
    678 F.3d 713
    , 724 (9th Cir. 2012) (en banc); United States v.
    Bryza, 
    522 F.2d 414
    , 422 (7th Cir. 1975).
    Defendants-Appellants’ argument that the statute does not
    apply to foreign employment relationships fares no better under our
    more recent precedent. “At the heart of the fiduciary relationship lies
    reliance, and de facto control and dominance.” United States v.
    Halloran, 
    821 F.3d 321
    , 338 (2d Cir. 2016) (alternation, quotation, and
    4
    citation omitted).   These characteristics are obviously inherent in
    employer-employee relationships—including the relationships in this
    case. Had the argument been properly raised below, I would hold that
    a cognizable fiduciary duty exists here.
    Defendants-Appellants, by virtue of their relationship with
    FIFA and CONMEBOL, had a fiduciary duty not to accept bribes or
    kickbacks, a duty that was explicitly laid out by the two associations’
    respective codes of conduct. Because, in my view, the element of
    honest services in § 1346 encompasses “the obligations of loyalty and
    fidelity that inhere in the employment relationship,” 
    Skilling, 561 U.S. at 417
    (Scalia, J., concurring), it follows that the statute is not
    unconstitutionally vague as applied to Defendants-Appellants.
    5
