    United States v. McPartland, Spota
    UNITED STATES COURT OF APPEALS
    FOR THE SECOND CIRCUIT
    August Term 2022
    (Argued: October 20, 2022              Decided: August 25, 2023)

    UNITED STATES OF AMERICA
    Appellee,
    -v.-
    CHRISTOPHER MCPARTLAND, THOMAS J. SPOTA,
    Defendants-Appellants.
    ––––––––––––––––––––––––––––––––––––
    Before:         LIVINGSTON, Chief Judge, NARDINI and MENASHI, Circuit Judges.
    Defendants-Appellants Christopher McPartland and Thomas J. Spota
    appeal from their judgments of conviction in the United States District Court for
    the Eastern District of New York (Azrack, J.). Following a five-week jury trial,
    Defendants-Appellants were convicted on counts of conspiracy to tamper with
    witnesses and obstruct an official proceeding, substantive witness tampering and
    obstruction of an official proceeding, obstruction of justice, and being accessories
    after the fact to the deprivation of the civil rights of a victim. The district court
    1
    sentenced Defendants-Appellants, principally, to five years’ imprisonment each.
    On appeal, Defendants-Appellants raise challenges to the district court’s
    admission of certain testimony at trial—in particular, testimony about
    subordinates’ fear of retaliation and testimony about bad acts that formed the basis
    for that fear of retaliation. Defendants-Appellants also challenge the district
    court’s denial of their application to admit the government’s bill of particulars, and
    McPartland challenges the district court’s denial of his motion for an evidentiary
    hearing and new trial. We find Defendants-Appellants’ arguments to be without
    merit. Accordingly, the judgment of the district court is AFFIRMED.

    DEBRA ANN LIVINGSTON, Chief Judge:
    This is an appeal by two former prosecutors—Defendants-Appellants
    Thomas J. Spota, previously the Suffolk County District Attorney, and Christopher
    2
    McPartland, previously the chief of the Government Corruption Bureau for the
    Suffolk County District Attorney’s Office (“SCDAO”)—who were convicted for
    their roles in covering up an assault carried out by James Burke, then the police
    chief for Suffolk County. After a five-week jury trial in the United States District
    Court for the Eastern District of New York (Azrack, J.), Spota and McPartland were
    found guilty of conspiracy to tamper with witnesses and obstruct an official
    proceeding, in violation of 
    18 U.S.C. § 1512
    (k); substantive witness tampering and
    obstruction of an official proceeding, in violation of 
    18 U.S.C. §§ 1512
    (b)(1),
    1512(b)(2)(A), 1512(b)(3), and 1512(c)(2); obstruction of justice, in violation of 
    18 U.S.C. §§ 1503
    (a) and 1503(b)(3); and being accessories after the fact to the
    deprivation of the civil rights of the assault victim, Christopher Loeb, in violation
    of 
    18 U.S.C. § 3
    .    On August 10, 2021, the district court entered judgment
    sentencing Spota and McPartland principally to five years’ imprisonment each.
    On appeal, Spota and McPartland argue that the district court improperly
    admitted what they characterize as irrelevant and inflammatory evidence—
    primarily, evidence that certain law enforcement officers feared retaliation if they
    were not complicit in the cover-up, as well as evidence of various bad acts carried
    out by Defendants-Appellants’ co-conspirator, Burke.        Spota and McPartland
    3
    also challenge the district court’s denial of their application to admit the
    government’s bill of particulars, and McPartland challenges the district court’s
    denial of his Rule 33 motion, Fed. R. Crim. P. 33, for an evidentiary hearing and
    new trial. Because we conclude that the district court did not abuse its discretion
    in admitting the evidence of the officers’ fear of retaliation, that any error in
    admitting the evidence relating to Burke was harmless, and that Spota and
    McPartland’s other arguments are without merit, we affirm the judgment of the
    district court.
    BACKGROUND
    I.   Factual Background
    In December 2012, Burke, the then–Chief of Department of the Suffolk
    County Police Department (“SCPD”), violently assaulted Loeb, who was at the
    time being held in an interrogation room in a police precinct.     Loeb had been
    arrested after a search turned up evidence that he had been burglarizing cars—
    including, notably, a vehicle belonging to Burke, from which Loeb appeared to
    have taken several items.    Three SCPD detectives in the Criminal Intelligence
    unit—Kenneth Bombace, Anthony Leto, and Michael Malone—interrogated Loeb.
    They yelled at, cursed, and slapped him, but could not extract a confession; Burke
    4
    himself then went into the interview room, where he fiercely punched, kicked,
    kneed, and screamed at Loeb, stopping only when the other officers intervened.
    After the assault, Burke ordered other high-ranking members of the SCPD—
    including then-Lieutenant James Hickey, who led the Criminal Intelligence unit—
    to ensure that the rank-and-file detectives who had witnessed or participated in
    the assault would not reveal what had occurred. Burke also enlisted the help of
    his long-time friend and mentor, Spota, the District Attorney of Suffolk County, as
    well as McPartland, one of Spota’s top prosecutors in the SCDAO, to help keep the
    witnesses quiet and to control the criminal case against Loeb.
    In the spring of 2013, the U.S. Attorney’s Office for the Eastern District of
    New York, with the assistance of the Federal Bureau of Investigation (“FBI”),
    opened a federal grand jury investigation into the assault.      Burke, Spota, and
    McPartland responded by using the influence afforded by their positions, along
    with various threats of retaliation, to conceal Burke’s crimes and to prevent
    witnesses from cooperating with the federal investigation. Thus, although the
    federal investigators served grand jury subpoenas in June 2013 on various
    potential witnesses—most notably, SCPD detectives Bombace and Leto—the
    investigation came up mostly dry. In December 2013, after determining that they
    5
    had insufficient evidence to pursue any charges, the U.S. Attorney’s Office and the
    FBI closed the investigation.
    But approximately one year later, the grand jury investigation was
    reinvigorated as certain key law enforcement witnesses—most notably Bombace,
    Leto, and Hickey—upon being immunized or entering into cooperation
    agreements, admitted to participating in the conspiracy and testified to Burke’s
    conduct. Shortly thereafter, Burke was charged for his role in the assault and in
    the cover-up. In February 2016, he pleaded guilty to the charges and later was
    sentenced to 46 months’ imprisonment. In October 2017, Spota and McPartland
    were indicted for their role in the conspiracy and charged with four counts:
    conspiracy to tamper with witnesses and obstruct an official proceeding,
    substantive witness tampering and obstruction of an official proceeding,
    obstruction of justice, and being accessories after the fact to the deprivation of
    Loeb’s civil rights.
    II.   The Trial
    Spota and McPartland’s trial commenced on November 14, 2019. Over the
    course of five weeks, the government presented evidence, including hundreds of
    exhibits and the testimony of dozens of witnesses, supporting the charges that
    6
    Spota and McPartland, together with others, carried out a concerted plan, which
    involved both witness tampering and the obstruction of the federal grand jury
    investigation, to cover up Burke’s assault on Loeb. Central to the government’s
    case was the testimony of Hickey, who spoke directly to the key roles of Spota and
    McPartland in the conspiracy, along with the testimony of Bombace and Leto, who
    discussed the pressures they were under to carry out Spota and McPartland’s
    desired ends.
    A. The “Inner Circle”
    As the government elicited at trial, Spota and Burke had a relationship that
    was widely known in the Suffolk County law enforcement community to be
    extremely close. They had been “close friends for over 40 years” and “Spota was
    Burke’s fiercest defender and protector.” MA-1130.1 Similarly, McPartland and
    Burke were characterized as having a close personal and professional relationship,
    with one witness describing them as “best friends” and saying that McPartland
    “would be the first person that Burke would turn to when he was in trouble.” 
    Id.
    Spota, Burke, and McPartland referred to themselves as “the administration.”

    Defendant-Appellant Christopher McPartland and Appendix of Defendant-Appellant
    Thomas Spota, respectively. Citations to “SPA-__” are to the Special Appendix of
    Defendant-Appellant Thomas Spota.
    7
    MA-1141 to -42.      And, according to the testimony elicited at trial, “the
    administration” had a reputation for being tightly knit and vindictive—“[a]n
    enemy of one [was] an enemy of all” and could expect to “face dire consequences.”
    MA-1132, MA-1135.
    The three also had a slightly larger clique—this one comprised of
    themselves, Hickey, and William Madigan, the Chief of Detectives of the SCPD—
    which they called “the inner circle.” MA-1129 to -30. Like “the administration,”
    the inner circle was built on a combination of loyalty and vindictiveness. Indeed,
    according to his testimony, Hickey joined the inner circle in 2005 through an
    incident targeting an “enemy” of Burke’s, Patrick Cuff.
    As Cuff himself testified, he first appeared on Burke’s blacklist following an
    incident in 1993, when Cuff was a lieutenant in the SCPD’s Internal Affairs Bureau.
    At that time, the Internal Affairs Bureau was investigating Burke for his alleged
    sexual relationship with Lowrita Rickenbacker, a woman with a prior felony
    conviction who was known to be actively engaged in criminal conduct, including
    possession and sale of illegal drugs, prostitution, and larceny.    As part of the
    investigation, Cuff interviewed Burke.       During the interview, Cuff, as he
    8
    acknowledged at trial, “chuckled” at Burke’s description of his own reputation as
    “sterling,” earning Burke’s ire. MA-1563.
    Hickey’s “induction” into the inner circle came over a decade later.        In
    September 2005, he encountered Cuff—who was now an inspector in the SCPD—
    deeply upset because his son had been arrested for possession of a service weapon
    and he believed the SCDAO had moved to upgrade the misdemeanor charge to a
    felony. Upon seeing Cuff upset, Hickey called Burke to tell him, and heard Burke
    in turn call Spota and McPartland into the room so Hickey could relay the
    information to them as well.      Hickey explained at trial that he called Burke
    because he knew Burke hated Cuff, and he believed that telling Burke would
    “ingratiate” him with the administration. MA-1407.       And it indeed appeared to
    do so—six or seven weeks later, Hickey was, in his telling, “suddenly promoted”
    to commanding officer of the Criminal Intelligence unit.        
    Id.
       To Hickey the
    lesson of this incident was clear—that friends of Burke’s “administration” would
    be rewarded, and enemies punished.
    Once “inducted,” and after Burke’s promotion to Chief of Department,
    Hickey acted as a liaison between the inner circle and his detectives in the Criminal
    Intelligence unit, specifically the four who comprised the “palace guards”—
    9
    Bombace, Leto, Malone, and Cliff Lent.     MA-1156.   The detectives frequently
    carried out tasks, both personal and work-related, for Burke.   In one instance,
    Leto tailed the stepson of Burke’s girlfriend, who had been giving her trouble,
    hoping to catch him breaking the law. In another, Burke had two detectives sent
    to confront his girlfriend’s contractor. Aware of Burke’s disagreements with a
    colleague in the SCPD, Bombace was ordered to serve as a “lookout” while another
    friend of Burke’s, Sanjiv Panchal, removed a GPS tracking device Panchal had
    previously placed on the colleague’s vehicle. Leto also testified to “spying on”
    county executive Steve Bellone and reporting back to Hickey about whom Bellone
    was meeting with. MA-772. These orders often came to them from Hickey; they
    knew the information they reported was being passed up the chain to Burke; and
    the “palace guards . . . would do anything and everything that the king, Burke,
    would ask them to do.” MA-1156.
    B. Loeb’s Interrogation and the Immediate Aftermath
    Several witnesses at the trial provided testimony regarding the events
    leading up to and including the assault of Loeb on December 14, 2012.        As
    relevant here, on that morning, Burke had reported that his SCPD-issued vehicle
    had been broken into and various items were stolen, including a “party bag”
    10
    containing, among other things, dildos, condoms, pornography, and Viagra.
    MA-338, MA-499 to -502.
    Although the Criminal Intelligence unit would not normally be involved
    with a vehicle break-in, at Burke’s request, Hickey assigned a number of his
    detectives to investigate. After initially reporting to Burke’s house to canvass the
    scene, detectives Bombace, Leto, and Malone were directed to report to the Fourth
    Precinct, where Loeb and another burglary suspect were in custody.
    As Leto testified at trial, the detectives felt pressure to secure a confession
    from Loeb, as he had burglarized “the chief’s” car—but their attempts were
    unsuccessful.   MA-775 to -76.     It was at this point that Burke arrived at the
    Fourth Precinct and became “upset” when told that Loeb had not confessed.
    MA-777. Burke then entered the interview room to confront Loeb, and after a
    brief exchange in which Loeb called Burke a “pervert,” Burke began violently
    assaulting Loeb—punching him in the head and body as Loeb was handcuffed to
    the floor, grabbing Loeb’s ears, and shaking and kneeing the detainee. MA-776
    to -77. Burke desisted only when the detectives physically pulled him away.
    Following the assault, the SCDAO proceeded with its prosecution of Loeb
    for the vehicle break-ins and thefts. Initially, the prosecution was overseen by
    11
    McPartland, then the Chief of the Government Corruption Bureau, even though
    car thefts would not normally be within his bureau’s purview.      Burke told Hickey
    that McPartland was handling the case so as to “take care of it for us.” MA-1166.
    But Loeb subsequently went public with his allegations of being assaulted in
    police custody. As a result, Spota faced considerable pressure around February
    2013 to transfer the case to a special prosecutor, which he ultimately did. When
    a special prosecutor was appointed from the Queens District Attorney’s Office,
    Spota and McPartland initially expressed that they were “very pleased” given
    their “very friendly” relationship with that office. MA-1199. Even still, Spota
    and McPartland asked Madigan to serve as a liaison between the special
    prosecutor and the police department, monitoring all interactions and “report[ing]
    back.” MA-1199 to -203; see also MA-563 to -64, MA-616.
    C. The Cover-Up
    Hickey testified that, in fact, Burke, Spota, and McPartland reacted to the
    public allegations with panic.       McPartland “immediately reach[ed] out [to
    Hickey], discussing the need for . . . [Hickey] to keep [his] guys quiet and tight”
    and telling him “that to keep Jimmy out of jail, . . . we need[] to keep the guys quiet
    and in line.” MA-1187 to -88. Spota also spoke with Hickey during this period,
    12
    inquiring whether the detectives were “towing [sic] the line.”            MA-1187.
    Hickey recalled meeting with Burke and McPartland in February 2013 to discuss
    potential explanations for Burke’s presence at the police station on the day of the
    assault.   During this meeting, Burke proposed various explanations, “and
    McPartland would okay [them] or not.” MA-1192. Ultimately Burke proposed
    saying that “he just popped his head in,” and McPartland approved of this
    explanation by nodding his head. MA-1191 to -95.
    There were “constant” inquiries from both Spota and McPartland during
    this time as to whether Hickey, as commanding officer of the Criminal Intelligence
    unit, could ensure that his men were “doing okay”—that they would “stay with
    the story and not tell the truth,” rather than “chang[e] their tune.” MA-1195 to -
    96.   This would become a common refrain.          Hickey recounted that “[e]very
    single time [he] saw Spota . . . [or] McPartland, in passing, in a meeting, on the
    phone, they would inquire, how are your men? How are the guys? How are
    they doing?” MA-1195. Hickey would then ask his detectives if everyone was
    “holding tight” and “good,” and report “back up the chain of command.” MA-
    1196 to -97. “[I]t was . . . a daily, nonstop, constant pressure [on Hickey] . . . to
    keep track of [his] men and to report back up the chain.” MA-1205.
    13
    Bombace and Leto also testified at trial about the cover-up from their
    perspective. Leto explained that after the appointment of the special prosecutor,
    Bombace, Leto, and Malone met with Hickey, who informed them of the
    appointment and told them “what [their] story was going to be . . . [if] the special
    prosecutor asked . . . about if [Burke] went into the room with Christopher Loeb.”
    MA-782. The detectives subsequently met with Burke himself, who told them
    that he “might have poked [his] head” into the interview room, which Bombace
    and Leto both testified to having understood to signify that this was the account
    they should give the special prosecutor. MA-557 to -58, MA-783.
    On June 25, 2013, Bombace and Leto received grand jury subpoenas as part
    of the federal investigation. On the same day, they informed Hickey that they
    had been served with subpoenas “[s]o that he would know that . . . [they] were . . .
    not going to rat out” and “[s]o he would pass it up the chain to Burke and
    everybody else”—including Spota. MA-784 to -85. Hickey, after failing to get
    in contact with Burke, called McPartland, who told him to “get [his] guys
    together,” “find out exactly what was said to them by the agents serving the grand
    jury subpoenas,” and “to report back [his] findings.” MA-1211 to -12. Hickey
    then met with his detectives, whom Hickey described as “extremely nervous,”
    14
    “scared,” and “very apprehensive.” MA-1213 to -14. That day, Burke met with
    Spota, McPartland, Madigan, and Emily Constant, who as Chief Assistant District
    Attorney was essentially the “number two” person in the SCDAO, at Spota’s
    home, where they discussed the subpoenas and the federal investigation. Burke
    later told Hickey that keeping his detectives quiet was Hickey’s new “full-time
    job,” MA-1218 to -19, and that his “only job was to keep [Burke] alive, to keep [his]
    guys calm, to keep them from ratting, to let them know if there was [sic] any
    changes,” MA-1230.
    In September 2013, ahead of a state court hearing related to the Loeb
    prosecution, Hickey, Burke, and McPartland met to prepare Burke, should he have
    to testify in the hearing, and to discuss which of Hickey’s detectives could testify
    in the alternative. 2   Burke and McPartland settled on Leto, because they
    perceived that he would be the most reliable. When Hickey commented that Leto
    was “not going to like it,” Burke became angry, observing that “this is what they
    signed up for. They want to make the most money, drive the nicest cars, have
    the nicest job, this is what they signed up for.”      MA-1245.     Leto—who was
    2 By this point, according to Hickey, Burke had repeatedly and openly
    acknowledged beating Loeb in conversations with both Spota and McPartland at which
    Hickey was also present. MA-1244.
    15
    separately tapped by the special prosecutor to testify—was upset and didn’t want
    to testify. But he nevertheless gave false testimony about what had happened on
    the day of Loeb’s arrest, denying that an assault had occurred.
    Bombace and Leto both admitted at trial that they lied to the special
    prosecutor when they parroted Burke’s false story that he had merely popped his
    head in during Loeb’s interrogation.       MA-558, MA-790.        Bombace likewise
    admitted to lying to the FBI during the federal investigation, denying that Burke
    had beaten Loeb.     MA-561.     When asked about their decision not to testify
    truthfully, both Bombace and Leto explained that they feared retaliation by Burke
    and his associates. For example, Leto explained that he feared his sons would be
    set up or falsely accused of a crime if he were to testify against Burke, specifically
    noting Burke’s “powerful friends,” Spota and McPartland.          MA-774, MA-786.
    Similarly, Bombace explained his fear that if he and Leto “told the truth, that [they]
    would be retaliated against, even with as much as a . . . targeted criminal
    prosecution.” MA-558.
    Hickey’s testimony hit on the same themes. When asked if he “[felt] like
    [he] had any choice in the matter in terms of [his] role,” Hickey replied,
    “Absolutely not.”    Specifically, he testified, “If I went against Burke, Spota or
    16
    McPartland, especially as someone that’s part of the inner circle . . . I’d be dead.
    I’d be finished.   I would be public enemy number one.”           MA-1205 to -06.
    Hickey—along with several other witnesses, including Leto—observed that, when
    Burke was named Chief of Department of the SCPD in 2012, he promptly demoted
    Cuff the maximum possible four ranks, after which Spota, McPartland, Burke,
    Hickey, and Madigan held a “demotion party.”
    In December 2013, Burke was notified by an FBI agent involved with the
    federal investigation of the assault on Loeb that the investigation was being
    closed—and Burke was cleared.       Hickey testified that Burke was “elated” and
    boasted that this is “what happens when you just hold tight.” MA-1252. Spota
    indicated to Hickey that his men had done “great,” while McPartland
    congratulated Hickey for a good job. MA-1253.
    D. The Federal Investigation Reopens
    The administration’s success, however, was only temporary. In September
    2014, Hickey learned that two Suffolk County detectives serving on the FBI gang
    task force had been asked to leave a proffer session in the Central Islip federal
    courthouse, prompting concern among the co-conspirators that the federal
    investigation had recommenced. Hickey located Burke, who immediately called
    17
    McPartland and placed him on speaker phone. McPartland first speculated that
    Bombace had decided to cooperate, before telling Hickey that he “need[ed] to take
    the temperature of [his] guys, find out what’s going on, and make sure that they’re
    all quiet.”   MA-1265 to -66.     That day, Spota also asked Hickey if his “guys
    [were] holding tight,” and whether “it look[ed] like any of them are cooperating
    or looking to cooperate.”       MA-1268.     By this time Burke was “extremely,
    extremely concerned,” and advised Hickey that he should make sure that he
    wasn’t being followed and that his conversations were not being intercepted.
    MA-1266, MA-1269.
    In early June 2015, Bombace informed Hickey that his attorney had heard
    from the U.S. Attorney’s Office that the federal investigation into Loeb’s assault
    had been reopened and that subpoenas would be forthcoming. Hickey testified
    that he informed Burke, who insisted they meet with Spota and McPartland the
    next day to explain the situation.
    Spota, McPartland, Burke, and Hickey discussed next steps and who might
    be cooperating with the FBI.      According to Hickey’s testimony, after Hickey
    suggested that Bombace may have been the one who “flipped,” Spota responded
    by saying “these guys can’t change their testimony now,” remarking further that
    18
    he would see to it that Bombace would never work in Suffolk County again if he
    cooperated. MA-1290 to -92. McPartland told Hickey to “find out if anyone’s
    talking, if anyone’s cooperating, and, if so, we will take immediate steps to
    discredit them.”   MA-1292.    Burke, addressing Spota, said, “Tommy, can you
    believe this? Can you believe that the feds are going to try to put me in jail for
    tapping some junkie thief on the top of his head?”        MA-1292.     Spota then
    reminded the group to be “careful for bugs and wiretaps.” MA-1293.
    At the end of the meeting, as Hickey started to leave, Burke told Hickey to
    remind his detectives of “what happens when you go against the administration.”
    MA-1309 to -10. According to Hickey, McPartland then added, “just ask John
    Oliva.” MA-1293.
    The government elicited testimony from Hickey and others explaining
    McPartland’s reference to John Oliva, a former SCPD detective.       Back in 2014,
    McPartland, with Spota’s authorization, obtained a warrant to wiretap Oliva after
    concluding that he was the likely source of unflattering leaks to a particular
    Newsday reporter who had authored articles critical of Burke.          Spota and
    McPartland were both active in monitoring the wire, which eventually captured
    Oliva leaking information, a possible felony offense. In September 2014, Oliva
    19
    was arrested and pleaded guilty to a misdemeanor for official misconduct. By
    referencing these recent events in discussing potential defectors among Hickey’s
    detectives, McPartland made his intentions clear—Spota and McPartland were not
    afraid to use the resources of their office to punish an enemy.
    Burke’s girlfriend, Barbara Craft, testified that throughout the summer of
    2015, Burke was on the phone with McPartland discussing the Loeb investigation
    and expressing concern that Hickey and his detectives were talking about him.
    Hickey testified that in August, after hearing from Bombace again about the
    building federal investigation, Hickey met with Burke and McPartland; there
    McPartland accused Hickey of having “lost control” of Bombace, whom he called
    a “rat.” MA-1314, MA-1318 to -19.
    According to Hickey’s testimony, Burke, Spota, and McPartland continued
    to pressure Hickey to maintain the cover-up throughout the summer of 2015 and
    into the fall. For a time, Hickey remained resolved, but the stress and anxiety
    from the cover-up continued to mount. Hickey experienced, among other things,
    hallucinations, memory loss, and confusion, eventually leading to his
    hospitalization in October 2015. A week after his hospital stay, Hickey himself
    was served with a federal grand jury subpoena. Shortly thereafter, Hickey hired
    20
    an attorney and began cooperating with law enforcement authorities, thus
    permitting the full scope of Burke, Spota, and McPartland’s cover-up to come to
    light.
    E. The Defense and Rebuttal Cases
    After the government rested, Spota and McPartland each proffered
    stipulations and related exhibits but called no additional witnesses in their
    respective defenses. 3 In rebuttal, the government called a witness to clarify an
    issue raised by the defense, relating to certain swipe card records of Spota’s and
    Hickey’s entries into the two buildings that housed the SCDAO during the
    relevant period. The parties then offered their summations.
    F. The Verdict
    The trial concluded on December 17, 2019, with the jury convicting both
    Spota and McPartland on all four counts in the indictment.
    3Constant, the former Chief Assistant District Attorney at the SCDAO, had
    testified earlier in the trial as a defense witness after being first called by the government.
    As a defense witness, her testimony called into question a number of aspects of the
    government’s case. For example, she testified to having had two conversations with
    Spota that suggested he did not know about either the Loeb assault or its cover-up until
    October 2015. She also testified that relations between Burke and Spota had cooled by
    2012, making cooperation between them less likely, and that Spota had legitimate
    concerns motivating his authorization of the Oliva wiretap.
    21
    III.   Subsequent Procedural History
    On February 27, 2020, McPartland moved for a new trial pursuant to Rule
    33 of the Federal Rules of Criminal Procedure and requested an evidentiary
    hearing in support of that motion. The district court denied the motion.
    On August 10, 2021, Spota and McPartland were each sentenced,
    principally, to five years’ imprisonment. This appeal followed.
    DISCUSSION
    On appeal, Spota and McPartland contend the district court erred in three
    respects: (1) its admission of evidence relating to the state of mind of the law
    enforcement officers who participated in the cover-up, Burke’s prior bad acts, and
    the bag stolen from Burke’s vehicle; (2) its denial of Defendants-Appellants’
    application to admit the government’s bill of particulars; and, only on behalf of
    McPartland, (3) its denial of McPartland’s Rule 33 motion for an evidentiary
    hearing and new trial. We address each argument in turn.
    I.   Evidentiary Challenges
    We review a district court’s evidentiary rulings for abuse of discretion and
    “will disturb an evidentiary ruling only where the decision to admit or exclude
    evidence was manifestly erroneous.” United States v. Litvak, 
    889 F.3d 56
    , 67 (2d
    22
    Cir. 2018) (internal quotation marks omitted). “Even if a decision was manifestly
    erroneous, we will affirm if the error was harmless.”        
    Id.
     (internal quotation
    marks omitted).
    Evidence is relevant if “it has any tendency to make a fact more or less
    probable than it would be without the evidence” where “the fact is of consequence
    in determining the action.”     Fed. R. Evid. 401.   A district court “may exclude
    relevant evidence if its probative value is substantially outweighed by a danger of
    one or more of the following: unfair prejudice, confusing the issues, misleading
    the jury, undue delay, wasting time, or needlessly presenting cumulative
    evidence.” Fed. R. Evid. 403.
    “We accord great deference to a district court in ruling as to the relevancy
    and unfair prejudice of proffered evidence, mindful that it sees the witnesses, the
    parties, the jurors, and the attorneys, and is thus in a superior position to evaluate
    the likely impact of the evidence.” United States v. Paulino, 
    445 F.3d 211
    , 217 (2d
    Cir. 2006) (internal quotation marks omitted). When reviewing a district court’s
    Rule 403 determination, we “generally maximize [the evidence’s] probative value
    and minimize its prejudicial effect.” United States v. LaFlam, 
    369 F.3d 153
    , 155 (2d
    Cir. 2004) (internal quotation marks and alterations omitted).
    23
    Rule 404(b) governs the admissibility of evidence of “other acts”—“crimes,
    wrongs, or acts” other than those charged in the indictment. Fed. R. Evid. 404(b). 4
    Such evidence is not admissible “to prove a person’s character in order to show
    that on a particular occasion the person acted in accordance with the character,”
    but it may be admitted “for another purpose.” Fed. R. Evid. 404(b)(1), (2). This
    Court “has adopted an inclusionary approach to other act evidence under Rule
    404(b), which allows such evidence to be admitted for any purpose other than to
    demonstrate criminal propensity.”          LaFlam, 
    369 F.3d at 156
     (internal quotation
    marks omitted). For example, evidence of uncharged criminal conduct that “is
    inextricably intertwined with the evidence regarding the charged offense . . . [or]
    necessary to complete the story of the crime at trial” is not typically excluded
    under Rule 404(b).       United States v. Robinson, 
    702 F.3d 22
    , 37 (2d Cir. 2012)
    (internal quotation marks omitted).           “To determine whether a district court

    notice requirements on the prosecution in a criminal case. See Fed. R. Evid. 404(b)
    advisory committee’s note to 2020 amendment. Pursuant to Rule 404(b)(3), the
    prosecution must generally provide the defendant with pretrial notice “in writing” that
    “identif[ies] the evidence that it intends to offer pursuant to the rule” and “articulate[s] a
    non-propensity purpose for which the evidence is offered and the basis for concluding
    that the evidence is relevant in light of this purpose.”

     This notice must be provided
    “in such time as to allow the defendant a fair opportunity to meet the evidence.” 
    Id.

    of this amendment are not implicated here.
    24
    properly admitted other act evidence, the reviewing court considers whether (1) it
    was offered for a proper purpose; (2) it was relevant to a material issue in dispute;
    (3) its probative value is substantially outweighed by its prejudicial effect; and
    (4) the trial court gave an appropriate limiting instruction to the jury if so
    requested by the defendant.” LaFlam, 
    369 F.3d at 156
    .
    A. Fear-of-Retaliation Testimony
    Spota and McPartland first contend the admission of testimony explaining
    that the officers participated in the cover-up out of a fear of retaliation was in
    violation of Rules 401, 403, 602, 701, and 404(b) of the Federal Rules of Evidence.
    We disagree.
    To begin, we discern no arbitrariness or irrationality in the district court’s
    determination that the fear-of-retaliation testimony was relevant “to explain the
    actions of the coconspirators [i.e., the officers] and to complete the story of the
    charged conspiracy.” SPA-3; see also MA-244 to -46, MA-250 to -52.5            Evidence
    of a co-conspirator’s state of mind may be relevant “to explain how a criminal
    5  The district court issued a written order, dated November 9, 2019, permitting the
    introduction of, among other things, the fear-of-retaliation testimony, the Oliva wiretap
    and prosecution, the Cuff incidents, and the Rickenbacker investigation. See SPA-1 to -
    9. This order was issued after the parties submitted various motions in limine relating to
    these categories of evidence.
    25
    [enterprise] developed,” “to help the jury understand the basis for the co-
    conspirators’ relationship of mutual trust,” United States v. Pipola, 
    83 F.3d 556
    , 566
    (2d Cir. 1996), or “to complete the story of the crime on trial,” United States v.
    Gonzalez, 
    110 F.3d 936
    , 942 (2d Cir. 1997) (internal quotation marks and alteration
    omitted). Here, without this testimony, the jury would have lacked a complete
    picture as to why the officers chose to participate in the cover-up, despite the stress
    and criminal penalties to which participation in a years-long cover-up would
    expose them.      Moreover, the officers’ fear of retaliation, along with their
    understanding of the administration’s willingness to operate corruptly, was
    necessary to explain why the officers interpreted the occasionally cryptic
    statements by Burke, Spota, and McPartland as instructions to lie—such as when
    Burke told Bombace and Leto that he “might have poked [his] head” into the
    interview room. MA-557 to -58; see United States v. Simels, 
    654 F.3d 161
    , 168 (2d
    Cir. 2011) (“[Testimony regarding prior] witness intimidation activities . . . of
    which [the defendant] was likely aware . . . was admissible to provide a basis for
    [the witness] (and the jury) to understand the full import of many of [the
    defendant’s] statements to [the witness].”). Given that the testimony of Hickey,
    Bombace, and Leto was critical to the government’s case, their explanations
    26
    regarding how Burke, Spota, and McPartland operated the conspiracy through
    fear of reprisal provided important context for the jury. Accordingly, we reject
    Spota and McPartland’s relevancy challenge.
    Moreover, we disagree with Spota and McPartland’s contention that the
    government’s use of the fear-of-retaliation testimony improperly served to
    establish the truth of the officers’ beliefs.     The government’s statements in
    summation, such as that “[r]etaliation is sure to follow” those who cross Burke,
    Spota, and McPartland, MA-1937, were said in the context of the court’s limiting
    instruction that the evidence—particularly the testimony relating to specific,
    purportedly retaliatory actions taken by Burke, Spota, or McPartland—was to be
    used only to consider the state of mind of the witnesses. In light of the highly
    probative nature of the evidence at issue, this limiting instruction was sufficient to
    prevent improper use of the testimony. See United States v. Reichberg, 
    5 F.4th 233
    ,
    244 (2d Cir. 2021) (“We presume that juries follow limiting instructions . . . .”
    (internal quotation marks and alteration omitted)).       We thus reject Spota and
    McPartland’s argument that the fear-of-retaliation testimony was misused in a
    manner that created unfair prejudice, and we conclude that their challenge to this
    testimony under Rule 403 is without merit.
    27
    Spota and McPartland also challenge the testimony under Rules 602 and
    701, which require, respectively, that a lay witness testify only to matters within
    his or her “personal knowledge,” Fed. R. Evid. 602, and offer opinion testimony
    based only on the “the witness’s perception,” Fed. R. Evid. 701(a). Defendants-
    Appellants note that, besides Hickey, the officers who related their fears of
    retaliatory conduct did not testify to having actually spoken to either Spota or
    McPartland about the Loeb affair, nor did they testify that Hickey ever
    communicated any direct threats from Spota or McPartland to them.
    On review, however, we disagree with Spota and McPartland’s contention
    that the fear-of-retaliation testimony was “sheer speculation” and “entirely based
    on [the officers’] imaginations.”      Br. of Appellant McPartland at 46–47.
    Bombace and Leto need not have spoken directly to Defendants-Appellants about
    the Loeb assault and cover-up in order to have personal knowledge that there was
    a possibility of retaliation by “the administration.”    Rather, an officer could
    perceive a possibility of retaliation—and fear that retaliation would happen—
    simply from working in the SCPD and experiencing the department’s culture, as
    Hickey, Bombace, and Leto all invariably did.    See United States v. Cuti, 
    720 F.3d 453
    , 458–59 (2d Cir. 2013) (“[P]ersonal knowledge of a fact is not an absolute to
    28
    Rule 602’s foundational requirement, which may consist of what the witness
    thinks he knows from personal perception.” (internal quotation marks omitted)).
    Accordingly, we conclude that the district court did not abuse its discretion in
    admitting this evidence under Rules 602 and 701.
    Finally, McPartland argues that the testimony about fear of retaliation—
    referring to the officers’ testimony describing their fears, as opposed to their
    testimony regarding the specific instances that informed those fears—was
    admitted as “backdoor propensity evidence” in violation of Rule 404(b). 6 Br. of
    Appellant McPartland at 44. On this point, we are unpersuaded.
    Simply put, the officers’ fear-of-retaliation testimony does not constitute
    “other crimes, wrongs, or acts” that fall under Rule 404(b). 7           The testimony is
    comprised of the officers’ statements about what they thought Burke, Spota, and
    McPartland might do if they did not cooperate in the cover-up.              Although this
    testimony may paint Spota and McPartland in a bad light, it is not evidence of
    other crimes, wrongs, or acts within the meaning of Rule 404(b)—the officers’
    6  Spota argues that the fear-of-retaliation testimony was inadmissible under Rules
    401, 403, 602, and 701—but he does not argue that the district court’s admission of the
    fear-of-retaliation testimony violated Rule 404(b). See Br. of Appellant Spota at 52.
    7 To the extent the fear-of-retaliation testimony dovetails with the evidence of
    specific incidents of retaliation, we discuss the application of Rule 404(b) in the following
    sections.
    29
    statements were merely lay opinion testimony that, as the district court stated,
    reveals the state of mind of the officers.      Accordingly, we conclude that
    McPartland does not present a colorable argument under Rule 404(b), and that the
    fear-of-retaliation testimony was properly admitted.
    B. The Oliva Wiretap and Prosecution
    Spota and McPartland next argue that the district court’s decision to admit
    evidence of the Oliva wiretap and prosecution was in violation of Rules 401, 403,
    and 404(b) of the Federal Rules of Evidence because, among other things, the
    wiretap was lawful and some testimony, such as a discussion of profane text
    messages, led to unfair prejudice that outweighed the probative value of the
    testimony. We find these arguments to be without merit.
    Here, we discern no abuse of discretion in the district court’s finding that
    the Oliva evidence was “inextricably intertwined” with the charged offenses and
    therefore outside the scope of Rule 404(b)(1)’s prohibition. SPA-5. According
    to Hickey’s testimony, when he met with Burke, Spota, and McPartland in June
    2015 to discuss the reopening of the federal investigation, McPartland pointedly
    said, “just ask John Oliva,” after Burke reminded Hickey of what happens to those
    who “go against the administration.”     MA-1397.      This statement—a threat to
    30
    any officers who were considering cooperating with the investigation—directly
    bears on whether McPartland committed the charged crimes. But to understand
    the reference to Oliva, it was necessary that the jury hear evidence about the Oliva
    wiretap and prosecution.     Thus, this evidence was properly admitted, not to
    prove anything about the defendants’ character (much less to show that any of
    their specific actions were in accordance with that character), but rather to make
    sensible to the jury key evidence of the charged offense.
    Additionally, we discern no abuse of discretion in the district court’s
    assessment of the Oliva evidence under Rule 403. It reasonably found that the
    evidence of the Oliva wiretap and prosecution was highly probative because it
    provided context for other relevant evidence—namely, the alleged threat by
    McPartland—and it involved conduct “not . . . any more sensational or disturbing
    than the crimes with which [the defendants were] charged.”         United States v.
    Roldan-Zapata, 
    916 F.2d 795
    , 804 (2d Cir. 1990).      Further, the district court’s
    limiting instruction, which reminded the jury that the Oliva wiretap and
    prosecution were lawful, served to lessen any prejudicial effect of the evidence—
    as did the district court’s instruction that the evidence “was admitted for only
    limited purposes” relating to understanding the relationships and motivations of
    31
    Defendants-Appellants and their co-coconspirators. SA-512.           Accordingly, we
    affirm the district court’s decision to admit the Oliva evidence.
    C. The Prosecution of Cuff’s Son and the Rickenbacker Investigation
    Spota and McPartland next contend that the district court’s decision to
    admit evidence related to the prosecution of Cuff’s son and the 1993 investigation
    into Burke’s relationship with Lowrita Rickenbacker was in violation of Rules 401,
    403, and 404(b).8 Defendants-Appellants argue that the district court improperly
    permitted a number of witnesses to testify about the charges against Cuff’s son,
    even though only Hickey’s testimony suggested any wrongdoing by Spota and
    McPartland in connection with those charges.          They also argue that the court
    erred in allowing multiple witnesses to discuss Burke’s relationship with
    Rickenbacker, including testimony that he had sexual relations in his police
    cruiser, as well as affairs with other prostitutes.
    8   Spota and McPartland also purport to challenge the admissibility of this
    evidence under Rule 802, the rule against hearsay. Their arguments simply state that
    certain testimony was hearsay, without further explanation. See, e.g., Br. of Appellant
    Spota at 42 (alleging that Hickey’s testimony that he knew Spota was responsible for the
    upgraded charge against Cuff’s son was “a baseless assertion, grounded in hearsay”); id.
    at 43 (stating that “granular details” about Burke’s affair with Rickenbacker were
    “introduced through lengthy hearsay”). As Spota and McPartland do not make any
    meaningful arguments on hearsay grounds, we do not consider whether the testimony at
    trial consisted of improperly admitted hearsay.
    32
    Again, we disagree that the evidence was inadmissible.         First, we agree
    with the district court that the evidence about Hickey’s and Cuff’s beliefs that the
    charge against Cuff’s son was to be upgraded was necessary “to complete the story
    of the charged conspiracy.” SPA-6. The account of the upgraded charge against
    Cuff’s son explains Hickey’s introduction to the inner circle, which in turn
    provides context for his role as the liaison between “the administration” and the
    Criminal Intelligence detectives. Without understanding Hickey’s place in the
    inner circle—including the loyalty to Burke that Hickey demonstrated in order to
    earn that place—the jury could not have understood why Hickey was entrusted
    with the all-important responsibility of keeping his detectives in line, but was at
    the same time subject to threats and pressure from Burke, Spota, and McPartland.
    As such, this is the sort of evidence “to explain the mutual trust that existed
    between coconspirators” that “[w]e have held repeatedly [to be] within the court’s
    discretion to admit.” United States v. Rosa, 
    11 F.3d 315
    , 334 (2d Cir. 1993); see also
    United States v. Williams, 
    205 F.3d 23
    , 33–34 (2d Cir. 2000) (“[E]vidence of [the
    defendant’s] prior criminal conduct with his co-conspirators was relevant . . . to
    help explain to the jury how the illegal relationship between the participants in the
    crime developed.” (internal quotation marks omitted)).
    33
    We also conclude that the district court did not abuse its discretion in
    finding that the risk of unfair prejudice from this evidence was not substantially
    outweighed by its probative value. See Fed. R. Evid. 403. Hickey’s and Cuff’s
    beliefs that the charge would be upgraded, and the fact that Hickey relayed Cuff’s
    distress to Burke, Spota, and McPartland, provided highly probative context about
    the administration and the inner circle. Meanwhile, any prejudicial effect against
    Spota and McPartland, based on either Hickey’s belief that they upgraded the
    charge or their participation in the discussion of Cuff, was lessened by the district
    court’s limiting instructions informing the jury of the legality of the prosecution of
    Cuff’s son and the limited purposes for which this evidence was admitted. See
    SA-512.   Additionally, we discern no abuse of discretion in the district court’s
    determination that the evidence about the prosecution of Cuff’s son, which was a
    lawful exercise of the SCDAO’s discretion, was “not more sensational or
    disturbing” than the obstruction charges against Spota and McPartland. SPA-6;
    see Williams, 
    205 F.3d at 34
     (finding “no undue prejudice” in admitting evidence of
    prior criminal conduct where “the evidence did not involve conduct more serious
    than the charged crime and the district court gave a proper limiting instruction”).
    34
    Evidence of the Rickenbacker investigation, meanwhile, was necessary to
    understand why Hickey’s phone call to Burke after learning about Cuff’s concern
    that his son would be indicted for a felony was meaningful enough to earn Hickey
    a place in the inner circle. As such, it too was necessary to complete the story of
    the charged conspiracy. Accordingly, the testimony regarding the Rickenbacker
    investigation was not improperly admitted as evidence of “other crimes, wrongs,
    or acts” under Rule 404(b). See Robinson, 
    702 F.3d at 37
    .
    We also conclude that the district court did not abuse its discretion in
    determining that the evidence about the Rickenbacker investigation was “critical
    to understand[ing] Burke’s hatred of Cuff,” and therefore more probative than
    unfairly prejudicial.   SPA-6 to -7, -10.    The only direct relation between this
    evidence and Defendants-Appellants was the testimony that Spota represented
    Burke in the investigation, but the district court’s limiting instruction that the
    representation was legal and ethical served to lessen any prejudicial effect against
    Spota. See SA-511. As such, we affirm as to the district court’s admission of this
    evidence.
    35
    D. The Remaining Cuff Incidents and Burke’s Other “Bad Acts”
    Finally, Spota and McPartland challenge the district court’s admission of
    testimony regarding the “party bag” stolen from Burke’s vehicle and Loeb’s
    subsequent reference to Burke as a “pervert”; the assorted tasks the detectives did
    at Burke’s behest; and the remaining incidents involving Cuff, namely Cuff’s four-
    rank demotion upon Burke becoming Chief of Department, and a separate
    instance in July 2015, when Burke sought someone to “take accurate attendance”
    at Cuff’s retirement party to see who was friendly with Cuff and thus should be
    considered an enemy, MA-1408 to -09. We first conclude that admission of the
    party bag was not in error.     On the other hand, we conclude that in certain
    instances, the district court erroneously admitted testimony regarding Burke’s bad
    acts, but that such errors were ultimately harmless.
    To begin, we conclude that evidence of Burke’s “party bag” was admissible
    under Rule 403.    The party bag and its contents provided context for Loeb’s
    labeling of Burke as a “pervert,” and for Burke’s assault on Loeb. That context,
    in turn, was relevant to understanding the cover-up, as executed by Burke, Spota,
    and McPartland.     Nor was the probative value of this evidence substantially
    outweighed by the risk of unfair prejudice toward Spota and McPartland, neither
    36
    of whom bore any relationship to the bag or its contents. As such, we conclude
    the district court did not err in admitting this evidence.
    Next, we consider the district court’s admission of evidence concerning
    Cuff’s demotion and retirement party as evidence of the co-conspirators’ state of
    mind. The logic underlying the district court’s determination is sound: testimony
    involving particular events offered to explain the co-conspirators’ fear of
    retaliation is not offered “to prove [the defendants’] character in order to show that
    on a particular occasion [the defendants] acted in accordance with the character,”
    Fed. R. Evid. 404(b)(1), but rather, to demonstrate the basis for the co-conspirators’
    beliefs. Accordingly, where the witness’s fear of retaliation is relevant, as it is
    here for the reasons previously discussed, we have upheld district courts’
    decisions to admit a witness’s testimony regarding past acts of reprisal that
    provide the foundation for his or her fear of the defendant. See, e.g., Simels, 
    654 F.3d at 168
     (“The Court . . . did not err in admitting evidence about violence
    committed by gang members, evidence relevant to [the witness’s] fear of
    reprisal.”); see also 1 Christopher B. Mueller & Laird C. Kirkpatrick, Federal
    Evidence § 4:37 (4th ed.) (“Other acts by the defendant may explain the conduct of
    other people, apparently in reaction. Often the proof shows threatening, violent,
    37
    or abusive behavior, which tends to prove fear on the part of victims or others, and
    knowing of that fear helps understand behavior that would otherwise be hard to
    decipher.”).
    As such, it was not error for the district court to permit Hickey and Leto to
    testify to their understanding that Burke demoted Cuff in retaliation for his role in
    the Rickenbacker investigation, and to permit Hickey to testify regarding the
    incident involving Cuff’s retirement party.        With regard to both of these
    witnesses, such testimony was offered as part of their explanations for why they
    feared retaliation from the administration—a point made clear by the district
    court’s instructions that such evidence should be considered only “to the extent it
    relates to the state of mind of the alleged co-conspirators of the defendants.” SA-
    513. For the same reasons, the testimony from Hickey, Bombace, and Leto about
    the various tasks the detectives performed for Burke—such as when Leto tailed
    the stepson of Burke’s girlfriend or spied on the county executive—was
    admissible. By illustrating the detectives’ willingness to follow Burke’s orders,
    that evidence further highlighted their fear of retaliation from Burke and the rest
    of the administration.
    38
    But this accounts only for some of the testimony involving the Cuff incidents
    and Burke’s other questionable acts that the district court permitted to come in.
    In addition to Hickey and Leto, four other witnesses—Dennis Sullivan, Stuart
    Cameron, John Meehan, and Cuff himself—testified about Burke’s demotion of
    Cuff, even though their states of mind were not at issue. Similarly, in addition to
    allowing Bombace to testify about Burke’s use of a GPS device to track a colleague,
    the court allowed Panchal, the individual who actually placed the device, to
    describe the incident.   To be sure, such testimony may be admissible in some
    circumstances in order to bolster the reasonableness of the co-conspirators’ fears
    by corroborating the events providing the foundation for their beliefs. See United
    States v. Everett, 
    825 F.2d 658
    , 660–61 (2d Cir. 1987) (explaining that evidence of
    “other crimes” is admissible to corroborate “crucial prosecution testimony,” so
    long as the corroborating testimony is “direct and the matter corroborated is
    significant” (internal quotation marks omitted)). But in the present case, though
    this testimony may otherwise have been admissible, we conclude that it was
    needlessly cumulative and unfairly prejudicial. In particular, by permitting six
    witnesses to testify regarding the Cuff demotion—including Cuff himself and
    three other non-conspirators—whatever probative value came from the
    39
    corroboration of Hickey and Leto’s fears was substantially outweighed by the
    potential prejudice associated with hearing again and again about Burke’s history
    of vindictiveness.9   The repetition of such testimony risked distracting the jury
    and transmogrifying the trial into a reckoning on Burke’s character. Accordingly,
    the testimony of the non-conspirators regarding these incidents should have been
    excluded.
    Nevertheless, we conclude that the district court’s errors were harmless in
    light of the myriad other evidence presented at trial. “A district court’s erroneous
    admission of evidence is harmless if the appellate court can conclude with fair
    assurance that the evidence did not substantially influence the jury.”            United
    States v. Al-Moayad, 
    545 F.3d 139
    , 164 (2d Cir. 2008) (internal quotation marks
    omitted). In the harmless error analysis, we consider “(1) the overall strength of
    the prosecution’s case; (2) the prosecutor’s conduct with respect to the improperly
    9   The other two purposes for which the district court admitted this evidence—to
    illustrate motive by “show[ing] that defendants considered Burke’s enemies to be their
    enemies,” and to show the close relationship between Burke, Spota, and McPartland—do
    not alter our analysis. SPA-6. The evidence about Cuff’s demotion and retirement
    party only marginally involves Spota and McPartland. Indeed, neither Spota nor
    McPartland figure in the testimony recounting Cuff’s demotion, aside from their
    participation in the “demotion party,” MA-1408, and neither Spota nor McPartland were
    mentioned at trial in relation to Cuff’s retirement. In any case, either of these purposes
    would have been achieved by permitting only Hickey and Leto to discuss these events—
    not the various other witnesses.
    40
    admitted evidence; (3) the importance of the wrongly admitted evidence; and
    (4) whether such evidence was cumulative of other properly admitted evidence.”
    United States v. McCallum, 
    584 F.3d 471
    , 478 (2d Cir. 2009) (internal quotation marks
    and alteration omitted).    “We have frequently stated that the strength of the
    government’s case is the most critical factor in assessing whether error was
    harmless.” United States v. Ramirez, 
    609 F.3d 495
    , 501 (2d Cir. 2010).
    Here, the government’s case was strong. Hickey was no doubt a critical
    witness whose testimony, if believed, left “no question [that] both . . . defendants
    [were] guilty of each and every single offense in the indictment.” MA-2043. But
    the government also presented other witnesses and evidence to corroborate
    Hickey’s testimony.     For example, phone records showed that multiple calls
    occurred between the phones attributed to Burke and McPartland, Burke and
    Hickey, and Burke and Madigan, on December 14, 2012, the day of the assault; and
    between the phones attributed to Spota and McPartland, Burke and Madigan,
    Spota and Madigan, McPartland and Madigan, Spota and Hickey, and Burke and
    Hickey, on June 25, 2013, the day of the subpoenas.          Similarly, analysis of
    cellphone locations provided corroboration for meetings about which Hickey
    testified.
    41
    Additionally, testimony from multiple witnesses corroborated Hickey’s
    account and, despite a lack of direct contact between these other witnesses and
    Defendants-Appellants, the testimony alluded to Spota and McPartland’s
    presence and role in the cover-up. For example, Leto testified to his belief that
    Burke reported to Spota, MA-769, and he explained that he informed Hickey about
    his subpoena so Hickey “would pass it up the chain to Burke and everybody else,”
    MA-784 (emphasis added). Hickey’s role in the cover-up, Leto perceived, was to
    “pass[] . . . information back to Chief Burke and all of them.” MA-846 (emphasis
    added).   Bombace testified that there was “a seamless existence [between] the
    DA’s office and the police department,” MA-617, and he spoke of his fear that, if
    he were to cooperate with the federal investigation, he might be targeted “[b]y
    Chief Burke and his associates . . . [w]hat [he] perceived was the District Attorney’s
    office, too,” MA-625. And Craft, Burke’s girlfriend, testified that in the summer
    of 2015, after the federal investigation was reopened, she heard Burke speak with
    McPartland over the phone about concerns that Hickey and Bombace “were
    talking about him.”       MA-1800 to -01.        Together, all of this testimony
    42
    corroborated Hickey’s account of the cover-up and strengthened the case against
    Spota and McPartland. 10
    Moreover, the evidence about Cuff’s demotion and retirement party, as well
    as the detectives’ “tasks,” comprised only a small part of the government’s case.
    In summation, the government specifically mentioned the demotion and the
    retirement party only once each, as examples of retaliation by Burke against an
    enemy; and in rebuttal the government made only one substantive reference to
    Cuff at all.   Discussion of the tasks performed by the detectives was similarly
    brief. These remarks by the government could have been made based only on
    the properly admitted testimony from Hickey and Leto and, accordingly, could
    not have misled the jury. As a result, we conclude that although the admission
    of cumulative evidence regarding Cuff’s demotion and retirement party, and the
    tasks performed for Burke, was in error, it was ultimately harmless.
    10Some evidence pointed in the other direction. Constant testified that by 2012
    Burke and Spota were not on good terms, making a coordinated cover-up less likely. See
    MA-1681. Still, the jury was entitled to discount that evidence and to credit Hickey’s
    testimony and its corroboration.
    43
    II.   Application to Admit the Government’s Bill of Particulars
    Next, Spota and McPartland challenge the district court’s denial of their
    application to admit the government’s pre-trial bill of particulars. In summation,
    the government argued that the June 25, 2013 meeting attended by Burke,
    McPartland, Spota, Madigan, and Constant, as well as another meeting of the same
    group in October 2015, were evidence of the cover-up. Spota and McPartland
    subsequently sought to introduce the government’s pre-trial bill of particulars,
    arguing that the government’s purported position in summation—that Constant
    was a co-conspirator—was inconsistent with the bill of particulars, which did not
    list Constant among the list of co-conspirators.     The district court denied the
    application, and in rebuttal, the government clarified it was not arguing that
    Constant was a co-conspirator. On appeal, Spota and McPartland repeat their
    arguments from trial.
    As above, we review the district court’s evidentiary rulings for abuse of
    discretion. Litvak, 
    889 F.3d at 67
    . We have previously stated that although bills
    of particulars “are not evidence in and of themselves,” “a prior inconsistent bill of
    particulars [may] be considered an admission by the government in an
    appropriate situation,” and may therefore be admissible under Rule 801(d)(2) of
    44
    the Federal Rules of Evidence. United States v. GAF Corp., 
    928 F.2d 1253
    , 1260–62
    (2d Cir. 1991) (emphasis added); see also Fed. R. Evid. 801(d)(2) (defining a
    statement made by an opposing party as “not hearsay”).          The inconsistency
    should be clear on its face. Cf. United States v. McKeon, 
    738 F.2d 26
    , 33 (2d Cir.
    1984) (explaining that when admitting a prior inconsistent opening statement under
    Rule 801(d)(2), the inconsistency “should be clear and of a quality which obviates
    any need for the trier of fact to explore other events”).
    Here, we discern no abuse of discretion in the district court’s denial of the
    application to admit the bill of particulars. There was no “clear” inconsistency
    about Constant’s status in the government’s statements. 
    Id.
     Indeed, there was
    no inconsistency at all, as the government did not state in its opening summation
    that Constant was a co-conspirator.      Moreover, even assuming arguendo there
    was an inconsistency generated by the government’s opening summation, the
    government’s clarification in rebuttal obviated any need to admit the bill of
    particulars. Accordingly, we affirm the district court’s denial of the application
    to admit the bill of particulars.
    45
    III.   Rule 33 Motion
    Finally, McPartland challenges the district court’s denial of his request for
    an evidentiary hearing and new trial under Rule 33.          Following the verdict,
    McPartland filed a Rule 33 motion seeking a new trial on the current record or,
    alternatively, an evidentiary hearing to establish, inter alia, that Hickey testified
    falsely as to critical parts of his trial testimony and that the government knew or
    should have known the testimony was false.           The district court denied the
    motion.
    We review the district court’s denial of a motion under Rule 33 for abuse of
    discretion. United States v. Vinas, 
    910 F.3d 52
    , 58 (2d Cir. 2018).
    A district court abuses its discretion in denying a Rule 33 motion
    when (1) its decision rests on an error of law or a clearly erroneous
    factual finding, or (2) its decision—though not necessarily the product
    of a legal error or a clearly erroneous factual finding—cannot be
    located within the range of permissible decisions.
    
    Id.
     (internal quotation marks and alteration omitted).          The district court
    itself “has broad discretion to decide Rule 33 motions based upon its evaluation of
    the proof produced.”     United States v. Gambino, 
    59 F.3d 353
    , 364 (2d Cir. 1995)
    (internal quotation marks omitted). “The ultimate test on a Rule 33 motion is
    whether letting a guilty verdict stand would be a manifest injustice.”           United
    46
    States v. Ferguson, 
    246 F.3d 129
    , 134 (2d Cir. 2001). As we have explained, to grant
    a new trial pursuant to Rule 33, “[t]here must be a real concern that an innocent
    person may have been convicted.” 
    Id.
     (quoting United States v. Sanchez, 
    969 F.2d 1409
    , 1414 (2d Cir. 1992)).
    Here, we discern no abuse of discretion in the district court’s denial of
    McPartland’s motion for a new trial and evidentiary hearing. It considered all
    the circumstances surrounding Hickey’s testimony, including those McPartland
    raises now on appeal. For example, McPartland argues on appeal that Hickey’s
    testimony regarding the February 2013 meeting—in which McPartland allegedly
    approved Burke’s story that he merely “popped his head” into the interrogation
    room—was clearly false because there is no reference to this meeting in either the
    government’s witness materials or Hickey’s own notes.         But the district court
    appropriately explained that the omission of the meeting from Hickey’s calendar
    was “not dispositive.”        See MA-2116 to -17.   Moreover, the district court’s
    conclusion that Hickey’s testimony was credible—and, at a minimum, not at the
    level of “patently incredible” required for a court to reject the jury’s credibility
    determination, Sanchez, 
    969 F.2d at
    1414—is located within the range of
    47
    permissible decisions and does not rest on an error of law or a clearly erroneous
    factual finding. See MA-2113 to -18.
    Further, McPartland incorrectly interprets the district court as requiring
    newly discovered evidence in order to make a successful Rule 33 motion. The
    district court’s reference to a lack of “newly discovered evidence” was merely to
    underscore the point that McPartland could have pressed his perjury arguments
    at trial; it did not require that he present new evidence. See MA-2120. Indeed,
    the district court expressly acknowledged that “Rule 33 does not require that a
    motion involve newly discovered evidence.” MA-2120 n.8. Thus, the district
    court did not impose an erroneous burden on McPartland.
    Finally, the district court did not abuse its discretion in finding that
    McPartland’s failure to press his perjury argument at trial counseled against relief.
    McPartland claims that he could not have asserted this argument at trial because
    he would have had to call as a witness the prosecutor who was, at the time, trying
    the case, thus leading to her disqualification under the advocate-witness rule.11
    But as the district court correctly noted, McPartland could have called government
    11 See Model Rules of Pro. Conduct R. 3.7(a) (Am. Bar Ass’n 2020) (“A lawyer shall
    not act as advocate at a trial in which the lawyer is likely to be a necessary witness . . . .”).
    48
    agents other than the prosecutor to testify about Hickey’s disclosures to the
    government; and if he truly needed the testimony of the prosecutor, he could have
    requested a hearing outside the presence of the jury.   Cf. United States v. Leung, 
    40 F.3d 577
    , 582 (2d Cir. 1994) (explaining that in some circumstances, the trial court
    should undertake an independent in camera review of government files to
    determine materiality of the evidence). Accordingly, the district court did not
    abuse its discretion in denying McPartland his requested relief.
    CONCLUSION
    For the foregoing reasons, we AFFIRM the judgment of the district court.
