    Opinion by Judge Milan D. Smith, Jr.
    SUMMARY*
    Criminal Law
    The panel affirmed the district court in a case in which
    Brent Wilkes was convicted of wire fraud, bribery,
    conspiracy, and money laundering, in connection with his
    long-running scheme to bribe former Congressman Randall
    “Duke” Cunningham.
    The panel held that the district court’s failure to compel
    use immunity for a proposed defense witness, Michael
    Williams, did not violate Wilkes’s right to a fair trial because
    Wilkes is unable to identify a direct contradiction between the
    testimony Williams would have offered at trial and testimony
    offered by an immunized government witness.
    The panel rejected Wilkes’s contention that determination
    of the amount of his criminal forfeiture by the district judge,
    as opposed to a jury, violated his Sixth Amendment right to
    a jury trial.
    The panel held that the district court did not err in
    denying Wilkes’s motion for a new trial based on “newly

    stating that Wilkes is innocent and court documents relating
    to a fraud scheme run by a co-conspirator in the bribery
    scheme. The panel stated that it is clear that the new
    evidence would not “probably result in acquittal.”

    OPINION
    M. SMITH, Circuit Judge:
    On November 5, 2007, a jury convicted Brent Wilkes on
    thirteen charges, including wire fraud, bribery, conspiracy,
    and money laundering, in connection with his long-running
    scheme to bribe former Congressman Randall “Duke”
    Cunningham. Wilkes was sentenced to 144 months in prison
    and ordered to pay a $636,116 criminal forfeiture or a
    $500,000 fine. Following our remand in United States v.
    Wilkes, 
    662 F.3d 524
    (9th Cir. 2011) (Wilkes I), Wilkes raises
    three issues in this appeal.
    Wilkes first argues that his right to a fair trial was violated
    under United States v. Straub, 
    538 F.3d 1147
    (9th Cir.
    2008)—which permitted a defendant to prove a Fifth and
    4                UNITED STATES V. WILKES
    Sixth Amendment violation by showing that “the prosecution
    granted immunity to a government witness in order to obtain
    that witness’s testimony, but denied immunity to a defense
    witness whose testimony would have directly contradicted
    that of the government witness, with the effect of so
    distorting the fact-finding process that the defendant was
    denied his due process right to a fundamentally fair trial.”
    
    Straub, 538 F.3d at 1162
    . Wilkes further argues that the
    district court violated his Sixth Amendment right to a jury
    trial because the amount of his criminal forfeiture was not
    determined by a jury. Finally, Wilkes argues that the district
    court erred in denying his motion for a new trial. These
    arguments are unavailing, and we affirm the district court.
    FACTS AND PRIOR PROCEEDINGS
    Wilkes created Automated Data Conversion Systems
    (ADCS)—named after an eponymous Department of Defense
    (DoD) program proposed by Wilkes—in order to pursue
    valuable defense contracts. Wilkes obtained and retained
    these contracts by virtue of his close ties to Congressman
    Cunningham. The details of Wilkes’s scheme are described
    in Wilkes I, 
    662 F.3d 530
    –31.
    At trial, the government introduced the testimony of 29
    witnesses, who testified to a significant number of bribes paid
    by Wilkes to Cunningham. In addition to presenting evidence
    of Wilkes’s payments to Cunningham, the government
    introduced evidence that ADCS failed to perform work
    required by the DoD contracts it had acquired, and that work
    performed by ADCS was of poor quality. In support of the
    latter proposition, the government introduced testimony from
    Wilkes’s nephew, Joel Combs. The government also
    introduced testimony from Michael Wade, a consultant hired
    UNITED STATES V. WILKES                      5
    by Wilkes to help ADCS obtain government contracts. Wade
    and Combs both testified about ADCS’s work scanning
    documents in Panama (the Panama Project), as well as
    testifying more generally about Wilkes’s scheme. Because
    Combs intended to invoke his Fifth Amendment privilege
    against self-incrimination at trial, the government granted
    him use immunity. The government had also entered into a
    favorable plea agreement with Wade in return for his
    testimony against his co-conspirators. Wilkes then requested
    use immunity for his witness, Michael Williams, who he
    contended would offer testimony that directly contradicted
    the testimony of Combs and Wade. The district court denied
    Wilkes’s request based on its conclusion that it could not
    compel the granting of immunity to a defense witness absent
    a finding of prosecutorial misconduct.
    On November 5, 2007, after four days of deliberation, the
    jury found Wilkes guilty on thirteen counts: one count of
    conspiracy, ten counts of honest services wire fraud, one
    count of bribery of a public official, and one count of money
    laundering. After the district court discharged the jury, it
    imposed criminal forfeiture against Wilkes in the amount of
    $636,116, or, in the alternative, a fine in the sum of $500,000.
    Wilkes appealed his conviction, alleging, inter alia, that
    his Fifth and Sixth Amendment rights had been violated by
    the district court’s failure to compel immunity for Williams,
    and that his Sixth Amendment rights had been violated
    because the district judge, rather than the jury, determined the
    amount of his criminal forfeiture. While his case was on
    appeal, we decided Straub, which clarified that a defendant
    could be entitled to compelled immunity for a defense
    witness in situations where that witness would directly
    contradict an immunized government witness’s testimony,
    6                UNITED STATES V. WILKES
    and where the failure of the defense witness to testify
    deprived a defendant of his right to a fair trial. 
    Straub, 538 F.3d at 1162
    . We remanded Wilkes’s case to the district
    court with instructions that it determine whether Wilkes was
    entitled to compelled immunity for Williams; we rejected all
    of Wilkes’s other claims.
    On remand, the district court held an evidentiary hearing,
    during which Williams proffered the testimony that he would
    have given at Wilkes’s trial had he been granted immunity.
    The district court concluded that Williams’s testimony did
    not directly contradict that of an immunized government
    witness. The district court also concluded that Williams’s
    failure to testify did not amount to a due process violation
    because he had no knowledge of the bribes paid to
    Cunningham, had no personal knowledge related to the
    charged offenses, and most of the conduct charged in the
    indictment occurred before Williams joined ADCS.
    Wilkes also filed a motion for a new trial on the basis of
    “new evidence,” consisting of declarations obtained from
    Cunningham corroborating Wilkes’s testimony that he had
    not bribed the congressman, and court records supposedly
    corroborating Wilkes’s testimony that money allegedly given
    to Cunningham as a bribe had instead been lost in a fraud
    scheme. The district court rejected the motion because the
    “new” evidence was available to Wilkes at the time of trial
    and “[did] not in any way establish a probability of acquitting
    him.”
    Wilkes now appeals both those rulings, and he renews his
    Sixth Amendment challenge to the district court’s imposition
    of a criminal forfeiture.

    JURISDICTION AND STANDARD OF REVIEW
    We have jurisdiction over this consolidated appeal
    pursuant to 28 U.S.C. § 1291. The question of whether a
    district court erred by refusing to compel use immunity is a
    mixed question of law and fact that we review de novo.
    United States v. Alvarez, 
    358 F.3d 1194
    , 1216 (9th Cir. 2004).
    Factual findings underlying the district court’s ruling are
    reviewed for clear error. 
    Id. DISCUSSION Wilkes
    raises three issues in this appeal. First, he argues
    that the district court erred in concluding that Williams was
    not entitled to compelled use immunity. Second, Wilkes
    argues that he has a Sixth Amendment right to have the
    amount of his criminal forfeiture decided by a jury. Finally,
    Wilkes argues that newly discovered evidence should compel
    us to grant him a new trial. We disagree, and affirm the
    district court.
    I. Compelled Immunity
    Wilkes contends that the district court’s failure to compel
    use immunity for Williams violated his right to a fair trial
    under Straub. In support of this argument, Wilkes points to
    eight alleged contradictions between Williams’s proffered
    testimony and testimony offered by Combs, who was granted
    use immunity, and Wade, who received a favorable plea
    agreement from the government. The record, however,
    makes clear that Williams never directly contradicts
    testimony offered by Combs or Wade.
    8                   UNITED STATES V. WILKES
    A. Legal Standard for Compelled Immunity
    In Straub, we held that a defendant could establish a Fifth
    and Sixth Amendment violation by showing that: “(1) the
    defense witness’s testimony was relevant; and (2) either
    (a) the prosecution intentionally caused the defense witness
    to invoke the Fifth Amendment right against
    self-incrimination with the purpose of distorting the
    fact-finding process; or (b) the prosecution granted immunity
    to a government witness in order to obtain that witness’s
    testimony, but denied immunity to a defense witness whose
    testimony would have directly contradicted that of the
    government witness, with the effect of so distorting the
    fact-finding process that the defendant was denied his due
    process right to a fundamentally fair trial.”1 
    Straub, 538 F.3d at 1162
    . Straub also recognized that “[a] survey of our
    opinions suggests that in the majority of cases where a
    defendant seeks to compel immunity for a witness, that
    witness’s testimony will not be ‘directly contradictory’ to that
    of the prosecution’s witness, or there will have been no
    distortion of the fact-finding process, and the district court
    may deny immunity on those bases.” 
    Id. at 1161.
    1
    Our cases make clear that government witnesses who are granted
    favorable plea deals in return for their testimony are encompassed by
    Straub’s use of the term “immunized.” See United States v. Young,
    
    86 F.3d 944
    , 948 (9th Cir. 1996) (“Of the remaining four witnesses who
    testified against Young, two . . . had entered into plea agreements with the
    government, and two . . . received immunity. In light of these plea
    agreements and grants of immunity, there is a serious danger that the
    government’s denial of immunity to Delfs—the only witness who could
    have impeached Drake as the government’s critical witness—distorted the
    fact-finding process.”).
    UNITED STATES V. WILKES                    9
    We have found direct contradictions where witnesses
    offer differing accounts of factual circumstances. For
    example, in Straub, immunized government witness Adams
    admitted that, if asked, he would deny that he had walked into
    a bar in 2003 and confessed to Mike Baumann that he had
    “just shot a guy.” 
    Straub, 538 F.3d at 1162
    . The defense
    sought to compel immunity for Baumann, who was prepared
    to testify that Adams, the key prosecution witness, had
    arguably confessed to the very crime attributed to Straub. 
    Id. at 1162–63.
    Similarly, in United States v. Young, the government
    offered testimony from John Drake to the effect that two
    defendants, Tamez and Young, used Drake as a middleman
    to distribute 
    cocaine. 86 F.3d at 946
    . Tamez and Young
    sought immunity for David Delfs, who was prepared to testify
    that he had heard government witness Drake state that he was
    “falsely accusing somebody as being [his] supplier in the
    Tri-Cities.” 
    Id. at 947.
    Delf’s testimony—that Drake said
    either Tamez or Young was falsely accused—directly
    contradicted Drake’s own testimony—that Tamez and Young
    both supplied him with cocaine. Accordingly, we remanded
    the case to the district court for the purpose of determining
    whether the failure to grant immunity had intentionally
    distorted the fact-finding process. 
    Id. at 949;
    see also
    Benjamin v. Prosper, No. 2:03–cv–1166, 
    2010 WL 4630252
    at *12–14 (E.D. Cal. 2010) (noting that proffered witness
    who would testify that she had stolen Sudafed directly
    contradicted police offer’s statement that the defendant had
    stolen the drugs).
    By contrast, in United States v. Alvarez we held that
    failure to immunize a defense witness was appropriate where
    that witness “had been to several ‘stash’ house locations and
    10               UNITED STATES V. WILKES
    would have testified that [the defendant’s] home was not one
    of those she 
    visited.” 358 F.3d at 1216
    . We held that “this
    does not directly contradict the testimony of the
    government’s witnesses that [the defendant’s] house was in
    fact used to store cocaine in 1996. In fact, [the defense
    witness] was not present during any of the shipments of
    cocaine to various ‘stash’ houses, so she was not in a position
    to directly contradict the government’s witnesses’ testimony
    that implicated [the defendant] in the scheme.” 
    Id. Our cases
    thus illustrate what Aristotle expressed more
    than two-thousand years ago—that “contradictory
    propositions are not true simultaneously.” Aristotle,
    Metaphysics, Book IV 1011b13–14. Thus, a witness directly
    contradicts another witness if their respective testimonies
    cannot simultaneously be true, although in this context the
    proffered defense testimony “need only support (as opposed
    to compel) a finding by the jury that it was ‘directly
    contradictory.’” 
    Straub, 538 F.3d at 1163
    . We next turn to
    the question of whether Williams’s testimony directly
    contradicts testimony given by either Combs or Wade.
    B. Combs’s Testimony
    Wilkes alleges that Williams’s proffered testimony would
    have directly contradicted immunized government witness
    Combs’s testimony in six respects: (1) the level of demand
    for Wilkes’s VP-Max Software; (2) the identity of the
    Panama Project Manager; (3) whether ADCS had billed the
    government for equipment that it had not purchased;
    (4) whether ADCS had billed for work that it had not
    completed; (5) the reason that Wilkes opposed bar-coding the
    equipment used in Panama; and (6) whether ADCS had billed
    the government for a useless “ROI Task Plan.”
    UNITED STATES V. WILKES                    11
    1. Demand for VP-Max Software
    When Combs started at ADCS in late 1995, he was tasked
    with selling document-scanning software (VP-Max) to the
    DoD. ADCS hoped to sell more copies of the software.
    However, after an initial software purchase, the DoD declined
    to purchase any more copies of VP-Max. Combs testified
    that Wilkes sent him to “creat[e] a demand amongst the
    military to buy the software” but that he did not discover
    much demand for the product and was unable to generate any
    additional sales. Combs further testified that Wilkes showed
    him a letter—written by Wilkes and signed by
    Cunningham—aimed at pressuring the DoD to purchase more
    VP-Max software. After Cunningham’s involvement, the
    DoD purchased more software.
    At the evidentiary hearing conducted by the district court
    for the purpose of ascertaining the contents of Williams’s
    potential testimony, Williams testified he was “familiar” with
    VP-Max, that he thought it was a worthwhile product, and
    that “there seemed to be” demand for the product. These
    general impressions about VP-Max’s merits do not directly
    contradict Combs’s testimony about his specific experiences
    selling VP-Max—both statements can simultaneously be true.
    2. Identity of the Project Manager in Panama
    In 1998, ADCS secured a contract to scan documents in
    Panama. Wilkes put his nephew Combs in charge of the
    project, despite the fact that Wilkes thought he was a “ball
    dropper.” At Wilkes’s trial, Combs testified that he was the
    manager of the Panama Project on October 27, 1998. Combs
    also testified on cross-examination that he was the project
    12               UNITED STATES V. WILKES
    manager before Williams was hired, and that he believed that
    Williams had been hired in November of “1998, 1999.”
    Williams testified that he was hired in September of 1998,
    and that he became the manager of the Panama Project
    “relatively soon after” that, a time period of “a couple of
    months.” Williams again does not directly contradict Combs,
    who noted that Williams took over the Panama Project
    sometime in November of 1998.
    3. Equipment for the Panama Project
    On October 27, 1998, ADCS submitted a $3 million
    invoice for equipment purchased in connection with the
    Panama Project. Combs testified that ADCS had not actually
    purchased any of the equipment listed on the invoice at the
    time it was submitted.
    Williams testified that “most of the equipment that was
    used [in Panama] was . . . there when [he] arrived.” He
    further testified that “subsequent to the equipment being
    there, [he] did an analysis on the invoices and the purchases
    of [that] equipment. And I did know, from that, that [Wilkes]
    did purchase it.” Finally, in response to the question of
    whether ADCS had ever invoiced the government for
    equipment it never purchased, Williams responded, “not to
    my knowledge.”
    None of this testimony contradicts what Combs actually
    said. Combs testified that the equipment listed on the
    October 27, 1998 invoice had not been purchased at the time
    ADCS submitted an invoice seeking payment for purchasing
    that equipment. By contrast, Williams stated after he had
    taken over the project, some time later he reviewed invoices
    UNITED STATES V. WILKES                   13
    and determined that Wilkes had purchased the equipment
    being used in the Panama project. It is entirely possible that
    the equipment was purchased between the time that ADCS
    submitted the invoice that Combs identified as false and the
    time that Williams observed that the equipment had been
    purchased.
    4. Billing for Nonexistent Work
    ADCS also submitted two invoices for services rendered
    on the Panama Project on October 27 and 28, 1998. Combs
    testified that ADCS had not actually completed the tasks
    reflected in the invoices at the time they were submitted. By
    contrast, Williams testified that “to the best of [his]
    knowledge” ADCS did not bill the government for work that
    it did not do, but admitted that “[he] didn’t always see the
    invoices that were submitted.”
    Combs’s testimony states that two invoices, submitted in
    late October 1998, billed the government for work that was
    not completed. Williams does not state that those two
    invoices accurately reflected work that ADCS had completed,
    nor is it clear that he could have done so, as he was not
    involved in the Panama Project at the time. Further,
    Williams’s testimony that he did not recall any fraudulent
    invoices being submitted does not contradict Combs, because
    Williams admitted that he did not see all of the invoices.
    5. Bar-coding Dispute
    Combs testified that the government wanted to place bar-
    codes on equipment used in the Panama Project for
    identification, but that Wilkes told Combs that he did not
    want the equipment labeled because “[h]e wanted to be able
    14              UNITED STATES V. WILKES
    to move it to other projects or anywhere,” and bar-coding
    would identify the equipment as belonging to the
    government. Combs further testified that the government had
    paid for the equipment, but that Wilkes had moved the
    equipment to other locations.
    Williams testified that the bar-coding problem was “that
    if the equipment belonged to ADCS and not the government,
    then by the government applying bar-codes to that equipment
    it would imply their ownership.” Williams further testified
    that it “was [his] understanding” that at the time the bar-
    coding dispute arose the government had not paid for the
    equipment. Finally, Williams testified that he and Wilkes had
    not talked about opposing bar-coding because ADCS was
    trying to steal the equipment.
    Combs testified about a private conversation that he had
    had with Wilkes. Even if Wilkes gave Williams other
    reasons for not bar-coding the equipment, that does not
    contradict Combs’s testimony about the meeting.
    Furthermore, Williams only states that “it was his
    understanding” that the equipment was owned by ADCS.
    Clearly he could have held that understanding concurrently
    with the events described in Combs’s testimony.
    6. ROI Analysis
    On September 30, 1998, ADCS submitted a $135,795
    invoice for an “ROI.” An “ROI Task Plan” was attached to
    the invoice. Combs testified that he prepared the task plan,
    but that he had no experience doing so. Combs also testified
    that the document was incomplete, and that when he
    submitted the document to the government “[t]here was
    immediate push-back” because the document was useless.
    UNITED STATES V. WILKES                   15
    Williams testified that ADCS was responsible for
    preparing an ROI report, and that ADCS had subcontracted
    that work to PricewaterhouseCoopers. He further testified
    that “to the extent that it was completed and delivered, [he]
    believed that [it was of value to the government].” Williams
    also admitted that he had never seen the “ROI Task Plan”
    appended to the September 30 invoice, and that it was not the
    document he prepared with PricewaterhouseCoopers.
    Williams and Combs appear to be referencing completely
    different documents. The document that Combs worked on,
    and which he describes as useless, titled “ROI Task Plan,” is
    appended to the September 30 invoice. Williams admits to
    never having seen that document, nor did he have any
    involvement with the Panama Project at that point.
    Williams’s testimony at most indicates that ADCS later
    completed a full ROI analysis, but does nothing to dispute
    Combs’s contention that the September 1998 invoice sought
    payment for poor-quality work.
    C. Wade’s Testimony
    Wilkes argues that Williams’s testimony would have
    contradicted Wade’s testimony in two respects: (1) whether
    DoD officials’ concerns about ADCS’s performance on the
    Panama Project were “justified,” and (2) whether ADCS
    planned a “change in focus” involving hardware sales. As
    with Combs’s testimony, Williams’s testimony does not
    directly contradict Wade’s.
    16               UNITED STATES V. WILKES
    1. DoD Officials’ Concerns about Wilkes’s Work
    in Panama
    Wade testified that Gary Jones and Paul Behrens, two
    officials with the DoD, expressed concerns over “pricing and
    performance,” including issues surrounding the inventory of
    equipment. Wade further testified that those concerns were
    “justified,” and that he and Wilkes had met to discuss their
    response. Wade noted that the plan was to meet the officials,
    and if Wilkes and Wade did not allay their suspicions, to
    involve Cunningham. Wade also testified that Bob Fromm,
    a different DoD official, expressed concerns, and that they
    were “justified.”
    Williams testified that government concerns that Wilkes
    was blocking the bar-coding effort to steal the equipment
    were not “justified.” He also testified that concerns about
    ADCS billing for work that it did not do were not “justified.”
    These statements do not directly contradict Wade’s testimony
    in the manner contemplated by Straub. Wade’s statement
    that the concerns were “justified” is a matter of opinion. Two
    parties can truthfully hold differing opinions at the same time.
    Accordingly, Williams’s testimony does not amount to a
    direct contradiction.
    2. Whether ADCS Planned a “Change in Focus”
    Wade also testified that he and Wilkes discussed a
    “change in focus” from “scanning to buying hardware and
    software.” Wade further testified that he and Wilkes would
    mark up, sometimes by 600 percent, the cost of the equipment
    sold to the government, which was more lucrative than
    providing scanning services.
    UNITED STATES V. WILKES                     17
    Williams testified that he did not believe ADCS was only
    awarded a hardware contract due to a “change in focus.” But
    this does not directly contradict Wade’s testimony regarding
    a specific conversation between Wade and Wilkes. Williams
    merely notes that, as far as he was aware, one specific
    contract awarded to ADCS for hardware was not awarded
    “because ADCS decided to have a shift in focus.”
    Wilkes thus fails the first prong of the Straub test. He is
    unable to identify a single direct contradiction between the
    testimony Williams would have offered at trial and testimony
    offered by an immunized government witness. Accordingly,
    the district court’s conclusion that failure to compel use
    immunity for Williams did not violate Wilkes’s right to a fair
    trial is correct.

    .
    II. Forfeiture
    Wilkes argues that determination of the amount of his
    criminal forfeiture by the district judge, as opposed to a jury,
    violated his Sixth Amendment right to a jury trial. Wilkes
    argues that Apprendi v. New Jersey, 
    530 U.S. 466
    (2000), and
    Alleyne v. United States, 
    133 S. Ct. 2151
    (2013), require that
    the jury find facts justifying an increase in either end of the
    range of the prescribed penalty. Wilkes further argues that
    Southern Union Co. v. United States, 
    132 S. Ct. 2344
    (2012),
    applied Apprendi and, by extension, Alleyne, to monetary
    penalties—which he contends includes criminal forfeiture.
    Wilkes’s argument is directly contradicted by binding
    Supreme Court precedent. In Libretti v. United States,
    
    516 U.S. 29
    , 48–49 (1995), the Court expressly held that
    there is no Sixth Amendment right to a jury verdict in a
    criminal forfeiture proceeding. The Supreme Court has
    18               UNITED STATES V. WILKES
    cautioned courts of appeals against concluding that “recent
    cases have, by implication, overruled an earlier precedent.”
    Agostini v. Felton, 
    521 U.S. 203
    , 237 (1997). Thus, “[i]f a
    precedent of [the Supreme] Court has direct application in a
    case, yet appears to rest on reasons rejected in some other line
    of decisions, the Court of Appeals should follow the case
    which directly controls, leaving to [the Supreme] Court the
    prerogative of overruling its own decisions.” Rodriguez de
    Quijas v. Shearson/Am. Express, Inc., 
    490 U.S. 477
    , 484
    (1989). In compliance with the Supreme Court’s instructions,
    we reject the argument that Southern Union implicitly
    overruled Libretti.
    III.   New Trial
    Finally, Wilkes moved for a new trial in the district court
    based on “newly discovered” evidence—declarations from
    Cunningham stating that Wilkes is innocent and court
    documents relating to a fraud scheme run by Tommy
    Kontogiannis, a co-conspirator in the bribery scheme. The
    district court denied the motion, noting that “[t]he evidence
    [Wilkes] brings to bear — Cunningham’s declarations and
    proof of the Kontogiannis fraud — was available to him at
    the time of trial, and, in any event, the Court is extremely
    confident that it does not in any way establish a probability of
    acquitting him.” We agree.
    In order to obtain a new trial based on newly discovered
    evidence, Wilkes must establish that: (1) the evidence is
    newly discovered; (2) his failure to discover the evidence
    sooner was not the result of a lack of diligence; (3) the
    evidence is material; (4) the evidence is neither cumulative
    nor merely impeaching; and (5) the evidence indicates a new
    UNITED STATES V. WILKES                   19
    trial would probably result in acquittal. United States v.
    Harrington, 
    410 F.3d 598
    , 601 (9th Cir. 2005).
    We need not address the first four prongs, because it is
    clear that the new evidence would not “probably result in
    acquittal.” 
    Id. at 601.
    In Wilkes I, we noted that “[t]his was
    not a close case . . . . While Combs’s testimony may have
    significantly helped the government’s case, prosecutors also
    presented over two-dozen other witnesses and extensive
    documentary evidence of Wilkes’s guilt.” Wilkes 
    I, 662 F.3d at 541
    . Wilkes argues that declarations obtained from
    Cunningham—which state that Wilkes never bribed
    Cunningham—and court documents related to a mortgage
    fraud scheme run by Cunningham’s associate Kontogiannis—
    which Wilkes argues show he lost money to the scheme
    rather than used Kontogiannis as a means to bribe
    Cunningham—would likely result in his acquittal, despite this
    mountain of evidence.
    Self-serving declarations by a convicted criminal,
    however, are unlikely to persuade a jury, especially where
    those statements are directly contradicted by Cunningham’s
    own sworn statements at his plea colloquy. The evidence of
    Kontogiannis’s fraud scheme also would not likely have
    resulted in acquittal because there is no new evidence to
    support the argument that Wilkes paid Kontogiannis as part
    of that scheme, instead of as a bribe to Cunningham.
    CONCLUSION
    For the foregoing reasons we AFFIRM the district court.
