    Judges, and Paul L. Friedman, Senior District Judge.*
    Opinion by Judge Friedman
    SUMMARY**
    Habeas Corpus
    The panel affirmed the district court’s denial of a
    
    28 U.S.C. § 2255
     motion to vacate a sentence after conviction
    of knowingly possessing a biological agent, toxin or delivery
    system for use as a weapon.
    The panel first affirmed the district court’s denial of
    petitioner Olsen’s claim that the prosecution suppressed
    information about the incompetence of the forensic scientist
    who first examined items that later were found to be
    contaminated with ricin. The scientist was fired after an
    internal investigation that was not completed until after trial.
    The panel explained that, although the information was
    favorable to Olsen, he was not entitled to habeas relief
    because the information was not material under Brady, given
    overwhelming evidence that Olsen intended to use the ricin
    as a weapon, and given that Olsen did not contest the fact that
    he produced and possessed ricin. The panel also affirmed the

    UNITED STATES V . OLSEN                    3
    district court’s denial of relief as to Olsen’s claim of
    ineffective assistance of counsel in connection with his Brady
    claim.
    The panel next affirmed the denial of relief as to Olsen’s
    claim that the trial was tainted by the presence of a biased
    juror who had extensive prior knowledge of the case and had
    repeatedly expressed a belief in Olsen’s guilt. The panel
    explained that the district court did not clearly err in
    determining that the juror was not biased, and that his
    inaccurate juror questionnaire responses about lack of
    knowledge of the case were due to honest oversights and the
    passage of time.
    Finally, the panel affirmed the denial of relief as to
    Olsen’s claim of cumulative error. The panel held that
    Olsen’s claim of an erroneous jury instruction was
    procedurally defaulted and without merit. The panel held that
    any error in the prosecutor’s alleged use of guilt-assuming
    hypothetical instructions was cured by a limiting instruction,
    and the panel was not persuaded that the question elicited
    answers that affected Olsen’s substantial rights or
    significantly damaged his case. The panel also held that the
    failure to disclose Brady material, considered alone (above)
    or in combination with the remaining alleged error, did not
    render the trial fundamentally unfair or violate due process.

    OPINION
    FRIEDMAN, District Judge:
    Kenneth Olsen was convicted in 2003 of knowingly
    possessing a biological agent, toxin, or delivery system for
    use as a weapon, in violation of 
    18 U.S.C. § 175
    . This court
    affirmed his conviction on direct appeal. See United States
    v. Olsen, 120 F. App’x 18 (9th Cir. 2004). In 2009, Olsen
    filed a motion to vacate, set aside, or correct his sentence
    under 
    28 U.S.C. § 2255
    , raising a number of grounds for
    relief. After holding an evidentiary hearing on one of those
    grounds, the district court denied the motion. This court
    granted a certificate of appealability as to four of Olsen’s
    claims: violation of Brady v. Maryland, ineffective assistance
    of counsel, juror bias, and cumulative error. We have
    jurisdiction under 
    28 U.S.C. §§ 1291
     and 2255. We affirm.
    I. Background
    Kenneth Olsen was an employee of Agilent Technologies,
    Inc., in Liberty Lake, Washington, where he worked as a
    computer support technician. In August of 2001, a co-worker
    discovered that a document labeled the Terrorist
    Encyclopedia, which referenced explosives and other
    disturbing matters, had been printed on a shared office
    printer. Agilent security identified Olsen as the person who
    printed the document. Further inquiry revealed that from his
    UNITED STATES V . OLSEN                     5
    office computer Olsen had extensively browsed internet
    websites involving poisons and killing, specifically
    conducting internet searches for phrases like “undetectable
    death pill.”
    Agilent security personnel and counsel interviewed Olsen,
    who offered innocuous explanations for his internet browsing
    that were not deemed credible. He claimed, for instance, that
    he searched for information on poison to help his son’s Boy
    Scout troop avoid poisonous berries, and that he viewed
    anarchist websites involving toxic chemicals because he
    wanted to learn to make safe household cleaners. Olsen was
    immediately placed on leave and escorted off the property
    without being allowed to return to his cubicle.
    The next day, the company decided to fire Olsen, and it
    sent employees to clear out the personal items from his
    cubicle. Within Olsen’s filing cabinets, the employees
    discovered a wealth of internet printouts and books on
    poisons and methods of harming people and exacting
    revenge. They also found test tubes and a wide assortment of
    other chemistry paraphernalia. Alarmed by their discovery,
    the employees placed the items into several boxes and took
    them to the Agilent security team, which in turn contacted the
    Spokane County Sheriff’s Office. A deputy sheriff responded
    and took custody of the items, and a detective later took them
    to the Washington State Patrol (“WSP”) crime laboratory.
    There, the items were examined by WSP forensic scientist
    Arnold Melnikoff.
    Melnikoff tested the items for the presence of various
    substances. Among the many items he examined were two
    test tubes containing an oily residue, a metal cup with a small
    amount of white “cakey” residue stuck inside of it, a glass
    6                UNITED STATES V . OLSEN
    bottle with similar residue caked on the bottom of the bottle,
    a bag of beans later identified as castor beans, and several
    bottles of medicine, including a bottle of Equate-brand
    allergy capsules. Melnikoff’s discovery that the test tubes
    contained castor oil, and that the beans appeared to be castor
    beans, alerted him that some of the substances might contain
    ricin, a highly deadly poison derived from castor beans.
    Because the WSP lab did not have the ability to test for ricin,
    Melnikoff contacted the FBI and arranged for it to analyze the
    test tubes, metal can, glass jar, and beans. Melnikoff then
    individually sealed each of the items for the FBI.
    The FBI in turn sent the test tubes, metal can, and glass
    jar to the United States Army Medical Research Institute of
    Infectious Diseases (“USAMRIID”), which subsequently
    notified the FBI that each tested positive for ricin. The FBI
    then took possession of the remaining items from the WSP
    lab and sent them to USAMRIID. Twelve items from
    Olsen’s cubicle ultimately tested positive for ricin. With
    respect to the Equate capsules, USAMRIID tested twelve
    pills for ricin, finding that one had a “high concentration” of
    the poison while three others also tested positive but “below
    the level of quantization.” Because the capsules had to be
    liquified for testing, however, it could not be determined
    whether the ricin was inside the tainted capsules or on their
    surfaces.
    Independent of Melnikoff’s contact with FBI laboratory
    personnel, the Spokane detective handling the case had
    already consulted the FBI about the matter. When
    USAMRIID confirmed that the first batch of items tested
    positive for ricin, the FBI took over the investigation.
    UNITED STATES V . OLSEN                           7
    Olsen was indicted in July 2002 for knowingly possessing
    a biological agent, toxin, or delivery system for use as a
    weapon, in violation of 
    18 U.S.C. § 175
    . In April 2003 a
    second indictment was returned, charging Olsen with
    possessing a chemical weapon in violation of 
    18 U.S.C. § 229
    . After a twelve-day jury trial in July 2003, Olsen was
    found guilty of both charges.1
    At trial, Olsen did not contest the fact that he produced
    and possessed ricin, but only that he did so “for use as a
    weapon,” 
    18 U.S.C. § 175
    , and that he intended to possess the
    ricin as a “chemical weapon,” 
    18 U.S.C. § 229
    . Defense
    counsel attributed Olsen’s actions to “an irresponsible sense
    of curiosity” about “strange and morbid things.” The
    prosecution, on the other hand, presented evidence that Olsen
    methodically researched numerous undetectable means of
    killing someone, investigated not only how to produce
    poisons but also various means of delivering them to a victim,
    purified the ricin he produced to enhance its toxicity,
    performed mathematical calculations to determine the
    maximum doses of certain common medications for a 150-
    pound person, and spiked the aforementioned Equate capsule
    with the ricin he produced.
    Arnold Melnikoff did not provide expert testimony at
    trial, but he testified about his handling of the items recovered
    from Olsen’s cubicle, the tests he performed on them, the
    reasons he contacted the FBI for assistance, and his
    packaging of the items for transfer to the FBI.
    1
    The district court conditionally dismissed the chemical weapon count
    prior to sentencing, by agreement of the parties based on a multiplicity
    issue. Olsen, 120 F. App’x at 19.
    8                 UNITED STATES V . OLSEN
    This court affirmed Olsen’s conviction on direct appeal,
    concluding, among other things, that the government
    provided “copious evidence” of Olsen’s intent to use the ricin
    as a weapon. The court remanded for resentencing, however,
    due to an error in the application of the Sentencing
    Guidelines. Olsen, 120 F. App’x at 19. Olsen eventually was
    sentenced to 121 months of imprisonment and 60 months of
    supervised release, and was ordered to pay restitution. He
    appealed the revised sentence, which this court affirmed. See
    United States v. Olsen, 280 F. App’x 624 (9th Cir. 2008).
    In 2009, Olsen filed his Section 2255 motion, raising
    numerous grounds for relief. The district court held an
    evidentiary hearing on one of these issues, Olsen’s claim of
    juror misconduct. Although the court initially decided to hold
    an evidentiary hearing on a second issue — a Brady v.
    Maryland claim premised on the suppression of information
    about Arnold Melnikoff — the court later determined that no
    hearing was necessary. The court did allow the parties to file
    briefs, however, along with exhibits that had been prepared
    for the evidentiary hearing, including several depositions and
    affidavits. The district court denied Olsen’s Section 2255
    motion in part on July 15, 2010, rejecting his juror bias claim.
    On November 9, 2010, the court rejected the remainder of
    Olsen’s claims and denied the motion in its entirety. The
    district court declined to issue a certificate of appealability on
    any issue, but this court granted a certificate with respect to
    the four issues presented here.

    637 F.3d 895
    , 901 (9th Cir. 2011).
    III. Brady Claim
    Olsen contends that the prosecution suppressed
    information seriously undermining the honesty and
    professional competence of Arnold Melnikoff, the WSP
    forensic scientist who first examined the items recovered
    from his cubicle that later were found to be contaminated
    with ricin. Had this information been available to Olsen at
    trial, he maintains, it could have been used to rebut the
    government’s argument that Olsen spiked the Equate pill with
    ricin: in light of Melnikoff’s record of laboratory
    incompetence, Olsen would have had a basis for arguing that,
    instead, Melnikoff inadvertently contaminated the pill and did
    not testify truthfully about the laboratory procedures he
    followed when examining Olsen’s items. In Olsen’s view,
    the contaminated Equate capsule was critical to the
    government’s case because it offered powerful evidence that
    Olsen possessed the ricin to harm someone, as required for
    conviction under 
    18 U.S.C. § 175
    , rather than merely out of
    a morbid fascination with poisons.
    Although Melnikoff did not perform the tests that
    identified Olsen’s possessions as containing ricin (nor testify
    as an expert at trial), he handled and extensively manipulated
    the items before they were transferred to FBI custody. An
    expert affidavit supporting Olsen’s Section 2255 motion
    concludes, based on the evidence presented at trial, that it is
    “highly probable” that Melnikoff contaminated the Equate
    10               UNITED STATES V . OLSEN
    capsule with ricin after handling the other, ricin-positive
    items. Melnikoff testified that he examined the Equate
    capsules not by individually removing them from the bottle
    with forceps, but rather by dumping them onto his laboratory
    bench, albeit on “a sheet of clean lab paper,” after he had
    examined other items on the same bench — which included
    scraping ricin-positive powder from some of these items.
    Melnikoff also does not appear to have changed gloves
    between handling each item that he examined, although his
    testimony was equivocal on this point.
    A. Background
    Before Melnikoff joined the WSP in 1989, he was the
    head of the Montana State Crime Laboratory, where his work
    included conducting hair sample analyses. A defendant
    named Jimmy Ray Bromgard, who was convicted in Montana
    of rape based largely on Melnikoff’s hair sample testimony,
    was later exonerated by DNA testing and released in 2002.
    An Innocence Project advocate who had worked on the
    Bromgard matter wrote to the Washington State Attorney
    General about Melnikoff’s expert testimony in that case and
    urged a review of his subsequent work in Washington.
    The WSP responded by launching an internal
    investigation of Melnikoff in October 2002 that included “a
    review of current work performance.” A letter advised
    Melnikoff of the allegations against him: that while employed
    in Washington, he “may have engaged in misconduct
    involving courtroom testimony and/or case analysis” and that
    he “may have misrepresented himself during the original
    employment process when he applied for a position with the
    Washington State Patrol.” Melnikoff was placed on
    administrative reassignment during the investigation. In
    UNITED STATES V . OLSEN                    11
    January 2003 two additional charges were added, stemming
    from Melnikoff’s expert testimony in a different Montana
    case where the defendant later was exonerated. These
    charges accused Melnikoff of offering statistical conclusions
    regarding hair sample identifications that were not consistent
    with scientific principles and of substantially overstating the
    number of cases in which he had conducted hair analyses.
    Documents generated during a WSP internal investigation
    are not available to the public or even to the employee being
    investigated until the WSP’s administrative decisionmaker
    issues his or her preliminary findings, in the form of an
    “Administrative Insight.” The Administrative Insight in the
    Melnikoff investigation was issued on August 4, 2003, after
    the conclusion of Olsen’s trial. By May 2003, however —
    nearly two months before the trial began — the investigative
    file for Melnikoff had already been completed and provided
    to the decisionmaker for review. This investigative file
    contained more than unsubstantiated allegations concerning
    the quality of Melnikoff’s laboratory work and his reliability
    as a witness. Instead, the investigative file contained
    comprehensive factual findings that investigators reached
    after scrutinizing Melnikoff’s laboratory work and his
    testimony as an expert witness in both Montana and
    Washington. Among other items, this file contained three
    separate evaluations of Melnikoff’s work in Montana and
    Washington, solicited for the investigation and conducted by
    peers and other experts in forensic laboratory analysis. These
    evaluations comprised an assessment of Melnikoff’s work in
    the Bromgard case by a panel of experts, an assessment of
    Melnikoff’s work in another Montana case by a forensic
    scientist, and, most notably, an assessment of Melnikoff’s
    work in 100 recent Washington cases, along with his
    courtroom testimony in twelve Washington cases, by a panel
    12                UNITED STATES V . OLSEN
    of Washington forensic chemists. This last assessment — the
    peer review of Melnikoff’s work in Washington — is referred
    to by the parties as the “Johnston Report”.
    The conclusions of these expert assessments were highly
    critical, calling into question Melnikoff’s diligence and care
    in the laboratory, his understanding of the scientific principles
    about which he testified in court, and his credibility on the
    witness stand. The Johnston Report, which reviewed
    Melnikoff’s Washington casework, concluded that his
    laboratory methods “seemed to be built around speed and
    shortcuts.” The panel noted the presence of unexplained
    contaminants in his laboratory, among other findings.
    The lead prosecutor in Olsen’s trial, Assistant U.S.
    Attorney Earl Hicks, was aware of the investigation into
    Melnikoff. In April of 2003, Hicks contacted the WSP
    laboratory director to inquire about the status of the
    investigation and to request any Brady material that might
    exist. Hicks was referred to Elizabeth Brown, an Assistant
    Attorney General for the State of Washington and legal
    counsel for the WSP. Although Hicks attempted to reach
    Brown, and the two repeatedly left voicemail messages for
    each other, they never actually spoke or communicated in
    writing about Hicks’s Brady inquiry.
    Because Hicks never spoke with AAG Brown, it appears
    that he never learned that an investigative file had been
    completed for Melnikoff in May 2003 nor anything about its
    contents. Olsen’s defense counsel never received the file or
    any of the documents it contained, including the critical
    assessments of Melnikoff’s laboratory work — counsel had
    possession only of the original charging documents laying out
    UNITED STATES V . OLSEN                    13
    the allegations against Melnikoff and informing him that an
    investigation was being conducted.
    During a pretrial hearing in late June 2003, AUSA Hicks
    informed the district court about the internal investigation
    into Melnikoff and acknowledged that he needed to “follow
    up and contact the State of Washington again.” But Hicks
    emphasized that no findings of any wrongdoing had yet been
    made. Hicks also characterized the WSP investigation —
    inaccurately, as it turns out — as pertaining solely to
    Melnikoff’s work conducting hair analyses in Montana
    during the 1980s and early 1990s. Olsen’s counsel explained
    that she had been “requesting materials about Mr. Melnikoff
    for quite some number of months now” based on her
    awareness of the investigation, his placement on
    administrative reassignment, and the fact that “his cases were
    being peer reviewed.” Her concern over the internal
    investigation material, she explained, arose from her
    knowledge that Melnikoff did some “testing and
    manipulation” of Olsen’s items and the possibility, in light of
    the allegations against him, of “cross contamination” if his
    handling of the evidence was not “appropriate and done with
    scientific standards.”
    The matter was revisited during trial on July 3, 2003, just
    before Melnikoff testified. By then the prosecutor had
    provided those documents within his possession to both the
    court and defense counsel, but these documents did not
    include Melnikoff’s investigative file or any of its contents
    such as the Johnston Report. The district court ruled that
    Melnikoff could not be cross-examined about the WSP
    investigation, based in part on the court’s erroneous
    understanding that “[t]he only issue here involved at all is
    whether or not there was some inaccuracy regarding his
    14                    UNITED STATES V . OLSEN
    testimony in Montana about comparing hair samples on rape
    and homicide cases” and because “there is nothing in here
    that I see that indicates that there was any problem at all
    during . . . his tenure with the state of Washington.” The
    court stated that because no findings had yet been made by
    the WSP decisionmaker, and because the investigation related
    solely to hair sample analysis in Montana, it would be “unfair
    to Mr. Melnikoff to allow counsel to delve into this issue,
    which isn’t at all relevant, and [does not] appear to in any
    way involve anything, as I understand it, his participation in
    this case would involve.” “I know of no indication,” the
    court reiterated, “that he acted inappropriately while with the
    State of Washington. There is no indication that he . . . didn’t
    operate properly under lab techniques.”
    Melnikoff subsequently testified before the jury about his
    handling and examination of the items recovered from
    Olsen’s cubicle. Defense counsel was permitted to elicit from
    Melnikoff only the fact that during his career complaints had
    been filed against him. On redirect, the prosecutor
    established that these complaints had been two or three in
    number. The prosecutor then asked Melnikoff if he had ever
    been disciplined or “ever been found to have done anything
    incorrectly,” to which Melnikoff answered “no.”2
    On August 4, 2003, after Olsen had been found guilty, the
    WSP decisionmaker issued his Administrative Insight,
    finding all the charges against Melnikoff to be proven. After
    Melnikoff was allowed to respond to the preliminary
    findings, they were made final, and Melnikoff was fired.
    2
    Later in the trial, Melnikoff was called back to the stand to testify that
    a lawsuit against him and the state of Montana by a former prisoner had
    just settled, with no admission of any wrongdoing.
    UNITED STATES V . OLSEN                    15
    These decisions were upheld on various levels of
    administrative and judicial review.
    B. Brady Standards
    “The three elements of a claim for a Brady violation are
    that ‘[t]he evidence at issue must be favorable to the accused,
    either because it is exculpatory, or because it is impeaching;
    that evidence must have been suppressed by the State, either
    willfully or inadvertently; and prejudice must have ensued.’”
    Gentry v. Sinclair, 
    693 F.3d 867
    , 887 (9th Cir. 2012) (quoting
    Strickler v. Greene, 
    527 U.S. 263
    , 281–82 (1999)). We find
    that the first element, favorability, has been satisfied in this
    case. We have no need to address the more difficult question
    presented here by the second element, suppression, because
    we conclude that the third element, materiality, has not been
    satisfied and that Olsen therefore is not entitled to relief.
    1. Favorability
    Evidence is favorable to the accused under Brady if it has
    either exculpatory or impeachment value. Gonzalez v. Wong,
    
    667 F.3d 965
    , 981 (9th Cir. 2011) (citing United States v.
    Bagley, 
    473 U.S. 667
    , 676 (1985)). The prosecution must
    disclose materials that are potentially exculpatory or
    impeaching. See Schad v. Ryan, 
    671 F.3d 708
    , 715 (9th Cir.
    2011); Hovey v. Ayers, 
    458 F.3d 892
    , 918 (9th Cir. 2006).
    The contents of the WSP internal investigation file clearly
    were favorable to Olsen.          The file contained three
    independent assessments completed by different experts and
    peers calling into question Melnikoff’s care in the laboratory
    and his fidelity on the witness stand. The Johnston Report,
    which reviews Melnikoff’s lab work in 100 recent
    16                UNITED STATES V . OLSEN
    Washington cases, criticizes his reliance on “speed and
    shortcuts,” and while it primarily focuses on problematic
    identifications of chemical substances, it also cites
    unaddressed contamination of laboratory materials, finding in
    one instance that “a defendant could have been prejudiced by
    an inaccurate test,” and in another that Melnikoff’s notes
    were contaminated with “reddish brown powder . . . probably
    from the fingers.” As evidence that Melnikoff’s lab work
    was characterized by sloppiness and haste, the report could
    have supported a defense theory that Melnikoff inadvertently
    contaminated the Equate capsule with ricin, undermining one
    piece of evidence of Olsen’s harmful intent.
    The Johnston Report also examined Melnikoff’s
    testimony in twelve Washington cases, noting “small
    misstatements made in a number of testimonies,” “a tendency
    for conclusions to become stronger as the case developed,
    from notes to written report to testimony,” and testimony that
    was either unsupported by the data or outside Melnikoff’s
    field of expertise. Although these findings largely bear on
    Melnikoff’s willingness to offer unwarranted scientific
    conclusions, they also speak to his truthfulness on a more
    general level, by suggesting a proclivity to shade his
    testimony in favor of the government’s case. As such, they
    could have been used to question the accuracy of his account
    about the care with which he examined Olsen’s items and
    thus call into question his credibility as a witness. See
    Gentry, 693 F.3d at 888 (evidence showing that the lead
    detective “was fired from his previous job for misconduct and
    that he had lied to obtain search warrants in other cases” was
    favorable “as it could have been used to impeach the
    credibility of [the detective] for truthfulness”) (citing Bagley,
    
    473 U.S. at 676
    ); Carriger v. Stewart, 
    132 F.3d 463
    , 479–80
    (9th Cir. 1997) (en banc) (evidence from corrections file of
    UNITED STATES V . OLSEN                    17
    prosecution witness bearing adversely on his credibility
    should have been disclosed under Brady).
    Echoing the district court, the government maintains that
    the contents of Melnikoff’s investigative file, including the
    Johnston Report and the other peer evaluations of his work,
    were not favorable to Olsen because the WSP decisionmaker
    had yet to make any findings. That proposition, for which the
    government offers no support, is at odds with the case law in
    this circuit, which repeatedly has held materials from ongoing
    investigations to be favorable under Brady. See, e.g.,
    Kohring, 
    637 F.3d at 903, 905
     (e-mails, memoranda, police
    reports, handwritten notes, and file regarding ongoing
    investigation into government witness); United States v.
    Price, 
    566 F.3d 900
    , 903 (9th Cir. 2009) (information
    respecting witness’s arrests, not convictions). Indeed,
    information bearing adversely on the credibility of a
    prosecution witness is favorable under Brady regardless of
    whether it was part of any investigation at all. See, e.g.,
    Gonzalez, 667 F.3d at 976, 981 (reports prepared by prison
    psychologists undermining credibility of government
    witness); United States v. Alvarez, 
    358 F.3d 1194
    , 1206–07
    (9th Cir. 2004) (exculpatory and impeachment material from
    probation officer’s files). The fact that the materials at issue
    here were generated because of an internal investigation is
    irrelevant. In the government’s view, apparently, no matter
    what the investigative file contained — even perhaps a sworn
    affidavit by Melnikoff himself admitting that he contaminated
    Olsen’s items with ricin — this evidence would not be
    favorable under Brady until the administrative decisionmaker
    concluded that such conduct violated WSP regulations. This
    position is untenable under Brady, and the government’s
    tenacious adherence to it is mystifying.

    2. Suppression
    In order for a Brady violation to have occurred, the
    favorable evidence at issue must have been suppressed by the
    prosecution, Price, 
    566 F.3d at
    907 (citing Strickler, 
    527 U.S. at 281
    ), and suppression may be either intentional or
    inadvertent. Strickler, 
    527 U.S. at 288
    ; Schad, 
    671 F.3d at 715
    . An “innocent” failure to disclose favorable evidence
    constitutes suppression even where there is no allegation that
    the prosecutor acted “willfully, maliciously, or in anything
    but good faith” — “sins of omission are equally within
    Brady’s scope.” Price, 
    566 F.3d at
    907–08 (citing Benn v.
    Lambert, 
    283 F.3d 1040
    , 1053 (9th Cir. 2002)); accord
    United States v. Pelisamen, 
    641 F.3d 399
    , 408 (9th Cir. 2011)
    (citing Strickler, 
    527 U.S. at
    281–82). “Brady has no good
    faith or inadvertence defense.” Gantt v. Roe, 
    389 F.3d 908
    ,
    912 (9th Cir. 2004).
    This case presents the complex question of whether
    suppression occurs under Brady and Kyles v. Whitley,
    
    514 U.S. 419
     (1995), when a federal prosecutor does not
    obtain or reveal information favorable to the defendant that
    is contained in a state internal investigation file. We need not
    reach that issue here, however, because we conclude that the
    information contained in Melnikoff’s WSP internal
    investigation file is not material under Brady.
    3. Materiality
    Even if evidence favorable to the defendant has been
    suppressed or not disclosed by the prosecution, there is no
    true Brady violation unless that information is material.
    Strickler, 
    527 U.S. at
    281–82. The Supreme Court and courts
    of appeals have found evidence to be “material” when “there
    UNITED STATES V . OLSEN                             19
    is a reasonable probability that, had the evidence been
    disclosed to the defense, the result of the proceeding would
    have been different.” Maxwell v. Roe, 
    628 F.3d 486
    , 509 (9th
    Cir. 2010) (quoting Strickler, 
    527 U.S. at 280
    ). “A
    reasonable probability is one that is sufficient to undermine
    confidence in the outcome of the trial.” 
    Id.
     (citing Kyles,
    
    514 U.S. at 434
    ). “The question is not whether the defendant
    would more likely than not have received a different verdict
    with the evidence, but whether in its absence he received a
    fair trial, understood as a trial resulting in a verdict worthy of
    confidence.” Strickler, 
    527 U.S. at
    289–90 (quoting Kyles,
    
    514 U.S. at 434
    ); see Hovey, 
    458 F.3d at 916
    . Reversal of a
    conviction or sentence is required only upon a “showing that
    the favorable evidence could reasonably be taken to put the
    whole case in such a different light as to undermine
    confidence in the verdict.” Williams v. Ryan, 
    623 F.3d 1258
    ,
    1274 (9th Cir. 2010) (quoting Kyles, 
    514 U.S. at 435
    ). This
    necessarily is a retrospective test, evaluating the strength of
    the evidence after trial has concluded.3
    3
    A trial prosecutor’s speculative prediction about the likely materiality
    of favorable evidence, however, should not limit the disclosure of such
    evidence, because it is just too difficult to analyze before trial whether
    particular evidence ultimately will prove to be “material” after trial. Thus,
    “there is a significant practical difference between the pretrial decision of
    the prosecutor and the post-trial decision of the judge.” United States v.
    Agurs, 
    427 U.S. 97
    , 108 (1976). As this court has noted, some trial courts
    therefore have concluded that the retrospective definition of materiality is
    appropriate only in the context of appellate review, and that trial
    prosecutors must disclose favorable information without attempting to
    predict whether its disclosure might affect the outcome of the trial. See
    Price, 
    566 F.3d at
    913 n.14 (noting favorably “the thoughtful analysis set
    forth by two district courts in this circuit” on the matter and citing United
    States v. Acosta, 
    357 F. Supp. 2d 1228
    , 1239–40 (D. Nev. 2005) (“[T]he
    ‘materiality’ standard usually associated with Brady for pretrial discovery
    purposes . . . should not be applied to pretrial discovery of exculpatory
    20                   UNITED STATES V . OLSEN
    To be considered material under Brady, the undisclosed,
    favorable evidence must either be admissible exculpatory
    evidence or be impeachment evidence, which “need not have
    been independently admissible to have been material.”
    Carriger, 
    132 F.3d at 481
    ; see also Price, 
    566 F.3d at
    911–12. Impeachment evidence is material “because ‘if
    disclosed and used effectively, it may make the difference
    between conviction and acquittal.’” Carriger, 
    132 F.3d at 481
     (quoting Bagley, 
    473 U.S. at 676
    ). “Evidence can be
    ‘used to impeach’ a witness even if the evidence is not itself
    admissible, even to impeach” — a written statement, for
    instance, that contradicts a witness’s testimony but is
    inadmissible as hearsay could still be used as a prior
    inconsistent statement to cross-examine the witness. Paradis
    v. Arave, 
    240 F.3d 1169
    , 1179 (9th Cir. 2001); Kohring,
    
    637 F.3d at 904
    . Inadmissible evidence that could have led
    to the discovery of admissible evidence also may qualify as
    material under Brady, although this circuit has not
    conclusively resolved the issue. Price, 
    566 F.3d at
    911–12;
    Paradis, 
    240 F.3d at
    1178–79.
    As noted, the materials contained in Melnikoff’s WSP

     (C.D. Cal.
    1990) (The standard of whether evidence would have changed the
    outcome “is only appropriate, and thus applicable, in the context of
    appellate review. . . . [I]t obviously cannot be applied by a trial court
    facing a pretrial discovery request.”)). See also United States v. Safavian,
    
    233 F.R.D. 12
    , 16 (D.D.C. 2005) (“The prosecutor cannot be permitted to
    look at the case pretrial through the end of the telescope an appellate court
    would use post-trial. Thus, the government must always produce any
    potentially exculpatory or otherwise favorable evidence without regard to
    how the withholding of such evidence might be viewed — with the benefit
    of hindsight — as affecting the outcome of the trial.”).
    UNITED STATES V . OLSEN                          21
    Olsen’s defense in at least two ways. First, defense counsel
    could have cross-examined Melnikoff about the reports
    contained in the file that indicate his lack of total candor on
    the witness stand and a tendency to shade his testimony in a
    manner buttressing the strength of the government’s case.
    See Kohring, 
    637 F.3d at
    905–07 (concluding that police
    department files documenting investigation into government
    witness for offenses calling into question his honesty could
    have been used to impeach witness). This line of inquiry
    could have been employed to undercut Melnikoff’s account
    of the care with which he handled Olsen’s possessions and
    hence his credibility.4 Second, the Johnston Report — which
    details Melnikoff’s slipshod work in the laboratory — could
    have been used to further advance the theory that it was
    Melnikoff who contaminated the Equate capsule with ricin.
    The defense could have pursued this theory by questioning
    Melnikoff about the report.
    The question under Brady is whether there is a reasonable
    probability that, had the Melnikoff information been
    disclosed, it would have led to a different result. Maxwell,
    
    628 F.3d at 509
    . “The mere possibility that an item of
    4
    Rule 608(b) of the Federal Rules of Evidence authorizes courts to
    permit inquiry into specific instances of conduct during cross-examination
    if they are probative of the character for untruthfulness of the witness —
    subject, of course, to the balancing analysis of Rule 403. Had Olsen’s
    attorneys cross-examined Melnikoff about the truthfulness of his
    testimony in prior cases, he either would have acknowledged or denied
    prior questionable conduct, and counsel would have been stuck with his
    answers and not allowed to pursue further inquiry. See United States v.
    Jackson, 
    882 F.2d 1444
    , 1452 (9th Cir. 1989). Nevertheless, the jury
    would have been able to assess his credibility when confronted and “to
    observe his demeanor when he answered the questions, which might have
    been telling.” Kohring, 
    637 F.3d at
    905 & n.4.
    22                   UNITED STATES V . OLSEN
    undisclosed information might have helped the defense, or
    might have affected the outcome of the trial, does not
    establish ‘materiality’ in the constitutional sense.” Barker v.
    Fleming, 
    423 F.3d 1085
    , 1099 (9th Cir. 2005) (quoting
    United States v. Croft, 
    124 F.3d 1109
    , 1124 (9th Cir. 1997)).
    “For purposes of determining prejudice,” therefore, “the
    withheld evidence must be analyzed ‘in the context of the
    entire record.’” Benn, 
    283 F.3d at 1053
     (quoting Agurs,
    
    427 U.S. at 112
    ).5
    Upon a careful review of the record, we conclude that
    there is no reasonable probability that the verdict would have
    been different if the favorable evidence had been disclosed.
    Even if Melnikoff’s credibility as a witness had been totally
    destroyed, we are confident beyond doubt that the jury would
    have found Olsen guilty, based on the overwhelming
    evidence presented by the government that he intended to use
    the ricin he possessed as a weapon. Despite the government’s
    failure to obtain and disclose Melnikoff’s internal
    investigation file, therefore, Olsen received “a trial resulting
    in a verdict worthy of confidence.” Gentry, 693 F.3d at 888
    (quoting Kyles, 
    514 U.S. at 434
    ).
    Because Olsen did not contend that he did not produce or
    possess ricin, the trial focused largely on the issue of intent:
    did he intend to possess the ricin as a chemical weapon or to
    use the ricin as a weapon? The contaminated Equate pill was
    one piece of evidence supporting Olsen’s intent, and to be
    sure, the prosecution highlighted this piece of evidence —
    5
    “The terms ‘material’ and ‘prejudicial’ are used interchangeably in
    Brady cases. Evidence is not ‘material’ unless it is ‘prejudicial,’ and not
    ‘prejudicial’ unless it is ‘material.’ Thus, for Brady purposes, the two
    terms have come to have the same meaning.” Benn, 
    283 F.3d at
    1053 n.9.
    UNITED STATES V . OLSEN                      23
    mentioning the capsule in its opening statement, devoting
    attention to it at various points during its case-in-chief, and
    emphasizing it during closing argument. Far from being the
    “lynchpin” of the prosecution’s case, however, as Olsen
    contends, the Equate pill was, as the government avers,
    “simply one more layer in an already overwhelming case
    against the Defendant.” Over the course of the twelve-day
    trial, the prosecution supplied devastating evidence about
    Olsen’s extensive research into poisons and killing indicating
    that these efforts were not prompted by mere curiosity but by
    a methodical effort to find an undetectable means of ending
    a victim’s life.
    The prosecution demonstrated not only that Olsen
    produced a substantial amount of ricin — enough to kill at
    least 75 people — but more tellingly that Olsen carried out
    extra steps to purify the ricin that he produced, enhancing its
    toxicity and deadliness. While ricin exists at 3 percent to 5
    percent purity in its initial state, Olsen refined the ricin in his
    test tubes to between 18 and 19 percent purity.
    The bulk of the government’s case, however, rested on
    the evidence of intent amply provided by Olsen’s internet
    research over the course of a year. This evidence simply did
    not comport with the defense theory at trial of an individual
    motivated only by curiosity about poisons. Instead, it showed
    that Olsen carried out a prolonged investigation into a variety
    of means to inflict harm on someone, with an ever-present
    focus on avoiding detection, during which he viewed
    materials that discussed not just how to create or obtain
    poisons but how to administer them to a victim. Ricin was
    but one of the deadly substances that Olsen investigated
    during the course of this research, although it was the one on
    which he focused the most attention, and ingestion of poison
    24               UNITED STATES V . OLSEN
    was only one of the methods of delivery discussed in the
    resources he accumulated. The government’s case did not in
    any way hinge on the theory that Olsen actually planned to
    use the spiked Equate capsule, and the capsule was just one
    indication of intent to which the prosecution pointed.
    Government investigators examined over 20,000 pages of
    internet proxy logs from Olsen’s computer — records of the
    internet websites that he viewed from the computer. A
    lengthy summary of those records, exceeding 200 pages, was
    introduced in evidence at trial and was discussed in detail
    during the testimony of FBI agents. This summary was
    combined with an illustrative timeline of Olsen’s internet
    research, allowing the prosecution to show the evolution of
    his activity over the course of months.
    From this evidence, the jury learned that Olsen had
    repeatedly viewed and in some instances printed out or
    purchased works with titles such as “How to Kill,” “Silent
    Death,” “Getting Even,” and the “Poisoner’s Handbook,”
    along with countless websites offering detailed instructions
    on both the production and delivery of poisons. The
    prosecution could not, of course, directly prove why Olsen
    consulted these materials or on what specific information in
    each source he focused. The proxy logs, however, recorded
    not only the websites that Olsen viewed but the actual words
    that he typed into internet search engines to locate materials
    of interest to him. As the prosecution characterized this
    evidence in closing argument: “What is unique about the
    evidence in this case is we have captured a thought process.
    We have captured his own words.” The proxy logs revealed,
    for instance, that at various times Olsen performed searches
    for the phrases “silent killers,” “death by poison,” “tasteless
    poison,” “hidden poison,” “undetectable poisons,”
    UNITED STATES V . OLSEN                    25
    “untraceable poisons,” “painless death,” “untraceable death
    pill,” “suicide pill overdose,” “how to get ingredients for
    suicide pill,” “deadly sleeping pills,” and “common
    ingredients for death by sleep.”
    Ricin was but one of the deadly substances that Olsen
    investigated during the course of his wide-ranging and
    nefarious explorations. For instance, he also acquired
    information about nicotine, which in its pure form is highly
    poisonous. Along with viewing articles on nicotine
    poisoning, Olsen performed searches for “acquiring liquid
    nicotine,” “making liquid nicotine,” “distilling nicotine,”
    “how do you extract nicotine from tobacco,” “nicotine
    isolation,” “how do you get pure nicotine,” and “pure nicotine
    buy.” He also viewed websites discussing lethal doses of
    nicotine and nicotine poisoning symptoms. A pervasive
    theme in his internet searches, however, was lack of
    detection, and the jury also learned that ricin is considered an
    undetectable poison whose deadly symptoms mimic the
    ailments of pneumonia and flu.
    The prosecution also presented evidence from Olsen’s
    internet browsing history showing that he viewed and
    searched for websites dealing specifically with the delivery of
    poison to a victim. Describing this evidence, the district
    court observed that Olsen “did much research on poisons,
    how to administer them, in what doses, and to be undetected.”
    The prosecution did not focus solely on Olsen’s interest in the
    delivery of ricin by ingestion and certainly not on the spiking
    of pills. To the contrary, the government repeatedly
    emphasized that ricin can be delivered to a victim through
    inhalation, injection by syringe, or ingestion.            The
    prosecution showed that needles and syringes were found in
    Olsen’s cubicle along with his ricin-related items, and that
    26                UNITED STATES V . OLSEN
    some of the ricin in his cubicle was in powder form, which an
    FBI agent testified could be inhaled or “sprinkled anywhere”
    for purposes of ingestion. Olsen’s interest in such methods
    of delivery was further demonstrated by the fact that he
    conducted searches for phrases like “inhaling ricin,”
    “atomizing a powder,” and “spraying a powder.”
    The jury heard an entire line of testimony about Olsen’s
    extensive research into “knock out drugs,” such as the so-
    called date-rape drug, and about how ricin could be
    administered without detection by first rendering the victim
    unconscious with such a drug and then injecting the victim or
    causing him or her to inhale the ricin. As the jury learned,
    Olsen also researched the maximum doses of certain common
    antihistamine and sleeping-pill drugs — including Equate —
    which if taken in excessive amounts can render a person
    unconscious. The government introduced notes in Olsen’s
    handwriting in which he listed the maximum doses, in
    milligrams, for four of these medications. Perhaps most
    incriminating of all, within these same handwritten notes
    Olsen mathematically calculated the weight in kilograms of
    a 150-pound person. The jury learned that Olsen’s wife, the
    woman with whom he was having an affair, and his former
    supervisor all weighed around 150 pounds.
    All of this evidence was prominently highlighted by the
    prosecution as evidence of intent during trial and closing
    argument. The record simply does not support Olsen’s claim
    that the presence of ricin in the Equate capsule was “pivotal”
    to the prosecution’s case. The contaminated pill was but one
    piece of evidence put before the jury for which no innocent
    explanation was plausible. It is likely for this reason that the
    district court judge who presided over the trial stated in the
    course of rejecting Olsen’s Brady claim that the Equate
    UNITED STATES V . OLSEN                            27
    capsule “was not that significant to the outcome of the trial,”
    and that “even if [the] allegation of cross-contamination by
    Mr. Melnikoff was conclusively proven as true, it would not
    have affected the outcome of the trial.”6
    Had the prosecution obtained and disclosed the evidence
    from Melnikoff’s WSP internal investigation file, the most
    that Olsen’s defense counsel could have accomplished with
    it would have been to raise a question about whether Olsen or
    Melnikoff contaminated the Equate pill with ricin and how
    credible Melnikoff was in describing the care he took in the
    laboratory. Viewing this evidence “in the context of the
    entire record,” Benn, 
    283 F.3d at 1053
     (quoting Agurs,
    
    427 U.S. at 112
    ), we find no reasonable probability that, had
    the evidence been disclosed, the result of the proceeding
    would have been different. See Maxwell, 
    628 F.3d at 509
    .
    IV. Ineffective Assistance of Counsel
    Olsen contends that although his trial attorneys requested
    Brady material about Melnikoff from the prosecutor, they
    rendered ineffective assistance under Strickland v.
    Washington, 
    466 U.S. 668
     (1984), by not attempting to obtain
    6
    Although Olsen directs our attention to the places in the record where
    the prosecution focused on the Equate pill, examination of these passages
    reveals, nearly without fail, that even in these very instances the
    prosecution’s case focused equally on other methods of delivering ricin.
    To take just one example, Olsen quotes a passage from the direct
    examination of an FBI agent in which the prosecutor asks: “Did you find
    any physical evidence consistent with those delivery methods you came
    to learn about?” Olsen quotes the beginning of the agent’s answer (“The
    Equate tabs. . . .”), but fails to note that the agent’s response continued:
    “Also, that ricin was found in a powder form in the metal bowl, and also,
    that we found needles and syringes since ricin can also be injected.”
    28               UNITED STATES V . OLSEN
    such material independently, through Washington’s public
    disclosure laws, by seeking a subpoena from the district
    court, or through other means.
    In our view, the existing record strongly suggests that
    none of the alternative means of obtaining Melnikoff’s
    internal investigation file would have been successful, and
    that his trial counsel did nothing wrong. We need not resolve
    this matter, however, because “Brady materiality and
    Strickland prejudice are the same.” Gentry, 693 F.3d at 889
    (citing Bagley, 
    473 U.S. at 682
    ); see United States v. Spawr
    Optical Research, Inc., 
    864 F.2d 1467
    , 1472 n.6 (9th Cir.
    1988) (“The Strickland standard for prejudice has been
    considered to impose virtually the same burden on the
    defense as the standard for materiality in Brady claims.”). If
    the withheld information does not constitute a Brady violation
    for lack of materiality, its absence likewise will not support
    an ineffective assistance of counsel claim. Gentry, 693 F.3d
    at 889. Because we have concluded that Olsen’s lack of
    access to the impeachment evidence about Melnikoff had no
    material effect on his defense under Brady, “that analysis is
    dispositive of the prejudice prong of an ineffective assistance
    claim based on the same evidence.” Id. Olsen’s claim of
    ineffective assistance therefore cannot succeed.
    V. Juror Bias
    Olsen’s next claim is that his trial was tainted by the
    presence of a biased juror who, unbeknownst to the parties
    and the district court, had extensive prior knowledge about
    the case and had repeatedly expressed a belief in Olsen’s
    guilt. Olsen maintains that this juror secured a spot on the
    jury by concealing his prior knowledge during voir dire and
    by lying about his own background in his juror questionnaire.
    UNITED STATES V . OLSEN                  29
    The district court held a two-day evidentiary hearing on this
    claim, after which it concluded that the juror was not biased
    against Olsen and that his inaccurate juror questionnaire
    responses were the result of honest oversights. We affirm the
    district court’s findings and conclusions.
    A. Background
    One of the jurors in Olsen’s trial was a man named
    Kenneth Leavitt. During voir dire, Leavitt did not speak up
    when the prospective jurors were asked whether anyone had
    “any particular exposure or knowledge” about the case.
    Defense counsel later asked those prospective jurors who had
    indicated having knowledge of the case to re-identify
    themselves and elaborate on their knowledge. Although
    Leavitt had not responded earlier, he then identified himself
    and explained: “Just months and months ago, a little news
    blurb on one of those news break shows, something about
    ricin or whatever.” Leavitt did not respond, however, when
    defense counsel inquired of the individuals who had heard
    about the case: “Have you talked about this case just in
    general terms with other people simply because it was an item
    of news interest? Is there anyone here who has done that?”
    Nor did he respond when counsel asked of the same group
    whether any of them had formed any opinions about the case.
    When Leavitt later was questioned individually by the trial
    judge, he said he knew of no reason why he could not be
    impartial.
    Leavitt previously was a business associate of an
    individual named Kevin Ryan, whose wife Jeanette Ryan was
    a friendly acquaintance of Olsen. Olsen worked as a massage
    therapist in addition to his computer-related employment, and
    Jeanette Ryan had gone to him for massage therapy for
    30                UNITED STATES V . OLSEN
    several years. Ms. Ryan attended portions of Olsen’s trial,
    which was held near her office, to show support for him and
    his family. On the first day that she attended the trial, she
    observed Leavitt — whom she had met a few times because
    of his work with her husband — in the jury box. That night,
    she mentioned this observation to her husband. Mr. Ryan, as
    he later testified at the evidentiary hearing, was “absolutely
    flabbergasted” and “sick to [his] stomach” by the revelation
    because, he testified, he and Leavitt had had multiple
    conversations about the Olsen case when it was in the news,
    during which Leavitt expressed an unwavering belief in
    Olsen’s guilt and demonstrated familiarity with the evidence
    against him.
    The Ryans’ concerns about juror Leavitt were brought to
    the attention of Olsen’s wife and then his counsel, although
    it appears that the full extent of Mr. Ryan’s allegations
    regarding his conversations with Leavitt became known to
    counsel only after sentencing.
    B. Discussion
    “The Sixth Amendment guarantees criminal defendants
    a verdict by an impartial jury.” United States v. Martinez-
    Martinez, 
    369 F.3d 1076
    , 1081 (9th Cir. 2004). “The bias or
    prejudice of even a single juror is enough to violate that
    guarantee.” United States v. Gonzalez, 
    214 F.3d 1109
    , 1111
    (9th Cir. 2000). “Accordingly, ‘[t]he presence of a biased
    juror cannot be harmless; the error requires a new trial
    without a showing of actual prejudice.’” 
    Id.
     (quoting Dyer v.
    Calderon, 
    151 F.3d 970
    , 973 n.2 (9th Cir. 1998) (en banc)).
    This court recognizes three forms of juror bias: (1) “actual
    bias, which stems from a pre-set disposition not to decide an
    UNITED STATES V . OLSEN                    31
    issue impartially”; (2) “implied (or presumptive) bias, which
    may exist in exceptional circumstances where, for example,
    a prospective juror has a relationship to the crime itself or to
    someone involved in a trial, or has repeatedly lied about a
    material fact to get on the jury”; and (3) “so-called
    McDonough-style bias, which turns on the truthfulness of a
    juror’s responses on voir dire” where a truthful response
    “would have provided a valid basis for a challenge for cause.”
    Fields v. Brown, 
    503 F.3d 755
    , 766–67 (9th Cir. 2007) (en
    banc) (citing McDonough Power Equipment, Inc. v.
    Greenwood, 
    464 U.S. 548
    , 554–56 (1984)). All three forms
    of bias potentially are implicated here, but we conclude that
    Olsen has not demonstrated bias under any theory.
    1. Actual Bias
    When an allegation of juror impartiality is raised after
    trial, the remedy is “a hearing in which the defendant has an
    opportunity to prove actual bias.” Dyer, 
    151 F.3d at 990
    (quoting Smith v. Phillips, 
    455 U.S. 209
    , 215 (1982)).
    “Actual bias is, in essence, ‘bias in fact’ — the existence of
    a state of mind that leads to an inference that the person will
    not act with entire impartiality.” United States v. Mitchell,
    
    568 F.3d 1147
    , 1151 (9th Cir. 2009) (quoting Gonzalez,
    
    214 F.3d at 1112
    ). “Actual bias is typically found when a
    prospective juror states that he can not be impartial, or
    expresses a view adverse to one party’s position and responds
    equivocally as to whether he could be fair and impartial
    despite that view.” Fields, 
    503 F.3d at 767
    . While actual
    bias may be revealed by a juror’s explicit admissions, more
    typically it is demonstrated through circumstantial evidence.
    Gonzalez, 
    214 F.3d at
    1111–12. A defendant bears the
    burden of demonstrating actual bias. Martinez-Martinez,
    
    369 F.3d at 1081
    .
    32               UNITED STATES V . OLSEN
    “The determination of whether a juror is actually biased
    is a question of fact,” Fields, 
    503 F.3d at
    767 (citing Dyer,
    
    151 F.3d at 973
    ), which this court reviews “for ‘manifest
    error’ or abuse of discretion.” 
    Id.
     (citing Gonzalez, 
    214 F.3d at 1112
    ). “At the same time, ‘[d]oubts regarding bias must be
    resolved against the juror.’” Martinez-Martinez, 
    369 F.3d at 1082
     (quoting Gonzalez, 
    214 F.3d at 1114
    ).
    At the evidentiary hearing conducted in this case, the
    district court heard testimony from Kevin Ryan that during
    the summer of 2002, when he and Leavitt worked together in
    the same office, they had at least a dozen conversations about
    the Olsen case, which was in the news at the time. According
    to Ryan, Leavitt was “adamant” about Olsen’s guilt and
    would “argue the points that he read in the paper or saw in the
    media, the evidence that they were gathering.” Ryan testified
    that Leavitt was familiar with the government’s evidence
    regarding the internet websites that Olsen had visited, and
    stated: “I think he probably even told me that he’d went
    online and looked at one of the websites.” During these
    conversations, Ryan said, he challenged Leavitt about
    whether valid opinions could be formed before trial,
    explaining that “all I knew of Ken Olsen was through my
    wife, [that he] was a kind and gentle man.” But according to
    Ryan, Leavitt held to his view that Olsen was guilty and was
    “very adamant” that the government would be able to prove
    its case. Ryan testified: “It seemed like every time he’d
    discuss it, whatever was brought up in the media that day,
    was one more notch in his belt to prove guilt.” According to
    Ryan, other employees within their office might also have
    participated in these conversations, although he could not
    name any other particular individuals besides himself and
    Leavitt who had taken part.
    UNITED STATES V . OLSEN                    33
    Ryan further testified that Leavitt had a reputation within
    their profession, the mortgage industry, for being untruthful.
    According to Ryan, the owner of the company for which the
    two men previously worked had later indicated to Ryan that
    Leavitt was untruthful. Ryan said he was told similar things
    by a bank representative involved in the industry, and that
    after he and Leavitt parted ways he learned from his own
    bank representative that his company’s account had been
    “red-flagged” because of Leavitt’s association with the
    company. Ryan also testified that while he and Leavitt were
    working together “it became evident over time that he
    continued to lie about several different things.”
    Ryan and Leavitt’s business relationship ended in the
    summer of 2002, after which the two men had no further
    contact. The conversations about Olsen’s case that Ryan
    recalled, therefore, took place a full year before Olsen’s trial
    began in July 2003.
    Leavitt testified at the hearing (which took place in May
    2010, seven years after Olsen’s trial) that he had no
    recollection of any conversations with Ryan about the Olsen
    case. He acknowledged that “if it was on the front headline
    — you know, if he said something, I may have commented
    back,” but he did not recall learning, in 2002, anything about
    a ricin investigation or anything at all about Olsen, nor that
    Ryan’s wife knew Olsen. Asked when he first heard of
    Olsen, Leavitt answered: “To the best of my knowledge, I
    mean, unless I read something in the paper or something, it
    was when I came in here . . . the same day that I came into
    court” for jury selection.
    The district court credited the testimony of both Ryan and
    Leavitt, and did not find their accounts to be mutually
    34                UNITED STATES V . OLSEN
    inconsistent. The court noted that the conversations Ryan
    described about Olsen’s case took place a full year before the
    trial, and that Leavitt admitted they could have taken place
    but simply did not recall one way or the other. The court
    cited a lack of any evidence that Leavitt, at the time of the
    trial, still held the beliefs that he expressed a year earlier or
    even remembered having them. It further noted that during
    voir dire Leavitt freely acknowledged having some
    familiarity with the case from the media, as did many
    prospective jurors, but that Leavitt assured the court that he
    could be impartial. In view of these considerations, the
    district court concluded that Leavitt’s responses on voir dire
    about his prior knowledge of the case were not false. Quoting
    Irvin v. Dowd, 
    366 U.S. 717
    , 723 (1961), for the proposition
    that juror impartiality is not rebutted by the mere existence of
    any preconceived notion about the defendant’s guilt, the court
    found that Leavitt was not actually biased against Olsen.
    “Whether a juror is dishonest is a question of fact[.]”
    Fields, 
    503 F.3d at
    767 (citing Dyer, 
    151 F.3d at 973
    ). Like
    the ultimate determination of actual bias, this finding is
    reviewed for clear error. 
    Id.
     (citing Riley v. Payne, 
    352 F.3d 1313
    , 1317 (9th Cir. 2003)). We are not firmly convinced
    that the district court’s findings about Leavitt’s honesty are
    wrong. Certainly, we are struck by the contrast between
    Ryan’s vivid recollection of having had many detailed
    conversations about the case and Leavitt’s own failure, a year
    later during voir dire, to mention these conversations or recall
    being exposed to anything more than “a little news blurb on
    one of those news break shows, something about ricin or
    whatever.” Ryan’s testimony about Leavitt’s reputation for
    untruthfulness gives us further pause. Yet we also are
    mindful that any casual “water cooler” conversations about
    the case at Leavitt and Ryan’s office, as these conversations
    UNITED STATES V . OLSEN                            35
    were later characterized, would have had much less
    significance at the time to Leavitt than to Ryan, whose wife
    had known Olsen for years and who himself had once met
    Olsen.7
    Leavitt was subpoenaed to testify at the evidentiary
    hearing in May 2010 with no advance warning that he was
    going to be questioned about his conduct during the Olsen
    voir dire seven years earlier, or about topical office
    conversations that took place a year before that. The district
    court was able to assess Leavitt’s demeanor as he was
    questioned about these matters, and it found his answers
    credible. See Thompson v. Keohane, 
    516 U.S. 99
    , 111 (1995)
    (noting that resolution of “factual issues,” including juror
    impartiality, “depends heavily on the trial court’s appraisal of
    witness credibility and demeanor”). We are not persuaded
    that this conclusion was manifest error or an abuse of
    discretion, as required to overturn a trial court’s factual
    findings or its conclusions about actual bias. See Fields,
    
    503 F.3d at 767
    .
    Furthermore, actual bias is not proven by the mere fact
    that Leavitt learned about the case from the media and formed
    7
    That supposition is reinforced by the fact that — according to Jeanette
    Ryan — Kevin Ryan even told his wife about these office conversations
    at the time that they took place. It was precisely because she knew that
    Olsen’s case had been discussed in her husband’s office a year earlier, she
    testified, that she was surprised to see Leavitt on the jury and immediately
    notified Olsen’s wife of her concern that he should not be there. W ith
    respect to Kevin Ryan’s personal familiarity with Olsen, he initially told
    investigators that he had never met Olsen but later testified at the
    evidentiary hearing that his wife reminded him about how he had met
    Olsen at his massage therapy office, where Olsen showed Ryan a
    technique to use on his wife’s shoulders.
    36                UNITED STATES V . OLSEN
    prior impressions about it a year before the trial. “[T]he
    Supreme Court has cautioned against presuming juror bias
    due to familiarity with news reports.” Crater v. Galaza,
    
    491 F.3d 1119
    , 1133 (9th Cir. 2007) (citing Irvin, 
    366 U.S. at
    722–23). “It is not required [that] jurors be totally ignorant
    of the facts and issues involved. . . . To hold that the mere
    existence of any preconceived notion as to the guilt or
    innocence of an accused, without more, is sufficient to rebut
    the presumption of a prospective juror’s impartiality would
    be to establish an impossible standard.” 
    Id.
     (quoting Irvin,
    
    366 U.S. at
    722–23).
    2. Implied Bias
    Even where actual bias has not been demonstrated, in rare
    instances a court will find implied bias, which is “bias
    conclusively presumed as a matter of law.” Mitchell,
    
    568 F.3d at 1151
     (quoting Gonzalez, 
    214 F.3d at 1111
    ). Bias
    should be presumed only in “extreme” or “extraordinary”
    cases. 
    Id.
     (citing Tinsley v. Borg, 
    895 F.2d 520
    , 527 (9th Cir.
    1990)). This court has recognized implied bias in only two
    contexts: first, “in those extreme situations ‘where the
    relationship between a prospective juror and some aspect of
    the litigation is such that it is highly unlikely that the average
    person could remain impartial in his deliberations under the
    circumstances,’” Fields, 
    503 F.3d at 770
     (quoting Gonzalez,
    
    214 F.3d at 1112
    ), and second, “where repeated lies in voir
    dire imply that the juror concealed material facts in order to
    secure a spot on the particular jury.” 
    Id.
     (citing Dyer,
    
    151 F.3d at 982
    ). Only the latter context — repeated lies
    during voir dire — is implicated here. Because implied bias
    is a mixed question of law and fact, review is de novo. 
    Id.
    (citing Gonzalez, 
    214 F.3d at 1112
    ).
    UNITED STATES V . OLSEN                     37
    Most of this court’s decisions presuming bias as a matter
    of law have involved situations “where the relationship
    between a prospective juror and some aspect of the litigation
    is such that it is highly unlikely that the average person could
    remain impartial in his deliberations under the
    circumstances.” Fields, 
    503 F.3d at 770
    . Typically the juror
    in question, or a close relative, “has had some personal
    experience that is similar or identical to the fact pattern at
    issue in the trial.” Gonzalez, 
    214 F.3d at 1112
    . See, e.g.,
    Mitchell, 
    568 F.3d at
    1148–49; see also Fields, 
    503 F.3d at
    768–770 (describing earlier cases). The theory is that even
    though some individuals in this position might be able to put
    aside their personal experiences, they nevertheless “would be
    lacking the quality of indifference which, along with
    impartiality, is the hallmark of an unbiased juror” — the court
    therefore “presume[s] conclusively” that these jurors will be
    affected in their deliberations by those experiences. Dyer,
    
    151 F.3d at 982
    . In every case where this form of implied
    bias has been recognized, the juror in question was not
    entirely forthcoming during voir dire about his or her
    personal experiences that were similar to the facts involved
    in the trial. See Fields, 
    503 F.3d at 773
    . That is not the
    situation presented here.
    Rather, Olsen contends that in addition to concealing his
    prior knowledge of the case and attitudes during voir dire,
    Leavitt also lied in his juror questionnaire about several
    matters pertaining to his own background. In Olsen’s view,
    these lies support a finding of implied bias under Green v.
    White, 
    232 F.3d 671
     (9th Cir. 2000), and Dyer v. Calderon,
    
    151 F.3d 970
     (9th Cir. 1998) (en banc), the two decisions
    from this court that have found implied bias “not on the basis
    of the juror’s past history, but on the pattern of lies the juror
    38                UNITED STATES V . OLSEN
    engaged in to secure her seat on the jury.” Green, 
    232 F.3d at 677
    .
    In Dyer, a juror’s brother had been killed in a manner
    similar to that with which the defendant was alleged to have
    killed his victims, but the juror said during voir dire that no
    family member had ever been the victim of any crime. Dyer,
    
    151 F.3d at 972
    . This court found that the record
    “conclusively” showed that the juror lied repeatedly to
    conceal the nature of her brother’s killing, first during voir
    dire and later when questioned by the state trial judge about
    the matter. 
    Id. at 979
    . The juror also “plainly lied” when she
    stated during voir dire that none of her relatives had ever been
    accused of an offense. This was no insignificant oversight:
    the juror’s own husband, charged with rape, had ended up in
    the same jail as the defendant and had spoken with him. 
    Id.
    at 973–94. Further contradicting her voir dire responses, the
    juror herself had been the victim of several crimes, and
    “nearly every close relative of hers had been arrested” for a
    crime at some point. 
    Id.
     at 980–81.
    In part because the district court had not made factual
    findings, this court did not rule on whether the juror was
    actually biased. Dyer, 
    151 F.3d at 981
    . Instead, based on the
    “magnitude” of the juror’s lies, as demonstrated by the
    evidence developed in an evidentiary hearing conducted by
    the district court, this court drew the inference that she “lied
    in order to preserve her status as a juror and to secure the
    right to pass on Dyer’s sentence.” 
    Id. at 982, 984
    . The
    circumstances therefore added up to “that rare case” where
    juror bias must be presumed. 
    Id. at 984
    . In the course of
    reaching this conclusion, the court observed: “A juror . . .
    who lies materially and repeatedly in response to legitimate
    inquiries about her background introduces destructive
    UNITED STATES V . OLSEN                      39
    uncertainties into the process.” 
    Id. at 983
    . Even if not
    motivated by a personal or vindictive bias against the
    defendant, the court explained, such a juror is unfit to serve.
    
    Id.
    These principles were later applied in Green v. White,
    where a juror engaged in a “pattern of misleading statements”
    in his juror questionnaire and during voir dire to conceal
    felony convictions that under state law would have
    disqualified him to serve as a juror. Green, 
    232 F.3d at 672
    .
    Unlike in Dyer, the juror had no personal experience “similar
    or identical to the fact pattern at issue in the trial.” Gonzalez,
    
    214 F.3d at 1112
    . Instead, the court’s finding of implied bias
    was based exclusively on the “destructive uncertainties”
    introduced by a juror who lies “materially and repeatedly in
    response to legitimate inquiries about her background.”
    Green, 
    232 F.3d at 677
     (quoting Dyer, 
    151 F.3d at 983
    ).
    Not surprisingly, Olsen stakes his claim of juror bias
    primarily on Green, attempting to draw parallels between the
    “pattern of misleading statements” in that case and the
    alleged lies by juror Leavitt here. In addition to accusing
    Leavitt of concealing his prior knowledge about the case,
    Olsen contends that Leavitt lied about his own background to
    get on the jury.
    Leavitt provided two answers in his juror questionnaire
    that he later acknowledged were inaccurate when questioned
    about them during the evidentiary hearing. First, Leavitt
    indicated that he never had a lawsuit filed against him.
    Actually, he had been sued a number of times. At the
    evidentiary hearing, he was confronted with evidence that a
    former landlord obtained a judgment against him for unpaid
    rent. Leavitt testified that he never was served with papers,
    40               UNITED STATES V . OLSEN
    went to court, or paid the judgment amount, and that he first
    learned about the judgment years after the Olsen trial, when
    he had to obtain a mortgage to buy a home. Leavitt also was
    questioned about whether he was sued by a particular bail
    bond company. He testified that to the best of his knowledge,
    the company never actually sued him, stating: “I had a traffic
    violation. They bonded me out. I did not show up for court.
    And they came and picked me up and took me in.” Asked
    about two apparent judgments against him by the company,
    Leavitt responded: “I never went to court for it. So, if they
    did, they got a summary judgment. And it probably affected
    my credit, and I probably paid it off. And it would have been
    at least ten years prior [to the trial].”
    Questioned about whether he was sued for writing bad
    checks in 1994, Leavitt answered that he “made bad
    mistakes” and “probably wrote bad checks,” but that he did
    not recall being sued and “never went to court for it.” When
    asked, “So let me understand. Every time you were sued you
    just didn’t go to court?”, he answered yes. Leavitt
    emphasized repeatedly that he did not recall having been
    served with papers to appear in court for any of those cases
    against him, that he fully believed he was answering the juror
    questionnaire honestly, and that he was “absolutely not”
    trying to hide any prior incidents from the court. Leavitt’s
    explanation for his lack of awareness about these lawsuits, as
    well as for the events in his life underlying them, was that
    when they took place in the 1990s he was in the throes of
    alcoholism. Later, as he put it, “I finally got married to a
    good woman who straightened me out,” and he thereafter
    “grew up and had children,” “became an adult,” and “put that
    past behind me.”
    UNITED STATES V . OLSEN                            41
    In his juror questionnaire, Leavitt also answered “no” to
    a question asking whether he had ever been convicted of a
    crime other than a traffic offense. At the evidentiary hearing,
    he explained this answer by stating that “at the time, I did not
    recall ever being convicted of any other crime.” Confronted
    with evidence that he had been prosecuted for and convicted
    of criminal trespass in 1994, for an incident at a bowling
    alley, Leavitt acknowledged the conviction and that he paid
    a fine for it but stated: “I honestly did not recall that event.”
    In explaining how he could forget such a thing, he stated:
    “It’s real simple. I drank an awful lot back then. I don’t
    now.”8
    The district court accepted Leavitt’s explanations for why
    he had forgotten about his trespass conviction and why he did
    not regard himself as having been sued in the other matters.
    It found these explanations credible, stating that “the Court
    does not find that he intentionally gave the Court false
    information” and that “mistaken, but honest juror responses”
    do not necessarily require a new trial. The court also
    observed that “there is no evidence that the inaccurate
    answers were an attempt to serve on a jury, let alone Mr.
    Olsen’s jury.” Noting its awareness that doubts regarding
    bias must be resolved against the juror, the court stated that
    it “does not hold a doubt” about Leavitt’s impartiality.
    Although we review de novo the question of whether bias
    should be presumed, because implied bias is a mixed question
    of law and fact, Hamilton v. Ayers, 583 F.3d at 1107, our
    8
    Leavitt also acknowledged that he had two or three DUI convictions
    — but the juror questionnaire specifically asked about convictions “other
    than traffic or driving offenses,” and Leavitt testified, reasonably enough,
    that he considered DUIs to be “traffic” offenses.
    42                   UNITED STATES V . OLSEN
    review is not carried out on an entirely blank slate.
    Concluding that a juror’s “repeated lies in voir dire” warrant
    an inference of bias requires first concluding that the juror
    lied in voir dire. See Dyer, 
    151 F.3d at 979, 981
    . That
    determination — whether a juror has been dishonest —
    remains “a question of fact,” about which the district court
    here made findings. Fields, 
    503 F.3d at 767
    ; see Patton v.
    Yount, 
    467 U.S. 1025
    , 1037–39 (1984). When this court has
    presumed bias from a juror’s lies, it has done so either where
    there were no factual findings by the trial court about the
    juror’s honesty or where those findings were clearly
    erroneous.9 Bias has been presumed only where the record
    “conclusively” showed that the juror “plainly” lied, and “no
    rational trier of fact could find otherwise,” Dyer, 
    151 F.3d at 979, 981
    , or where the trial court’s “erroneous factual
    finding” that the juror was honest constituted “clear error . . .
    not supported by any evidence” and the “only reasonable
    inference” from the facts was that the juror lied. Green,
    
    232 F.3d at 676
    .
    The district court in this case credited Leavitt’s
    explanation that by the time of Olsen’s trial he no longer
    remembered having the opinions about the case that he had
    expressed a year earlier. As discussed above, we do not
    regard this finding as clearly wrong. We take the same view
    9
    In Dyer, “the facts were not properly developed by the state court,”
    negating any presumption of correctness deriving from federal habeas law,
    and the district court did not make factual findings, despite having
    conducted an evidentiary hearing. This court therefore addressed the
    question of implied bias in the first instance, based on the record generated
    by the evidentiary hearing. Dyer, 
    151 F.3d at 979, 981
    . In Green, this
    court found implied bias only after rejecting, as “clearly erroneous,” the
    state courts’ factual determination that the juror did not lie about his
    criminal history during voir dire. Green, 
    232 F.3d at 678
    .
    UNITED STATES V . OLSEN                    43
    about Leavitt’s claim that the omissions in his juror
    questionnaire were honest mistakes. Unlike a situation where
    the juror’s conduct “defies an innocent explanation” and
    where the trial court’s finding to the contrary is “nearly
    inexplicable,” Dyer, 
    151 F.3d at 979, 981
    , here it is not at all
    obvious from the record that Leavitt was dishonest during
    voir dire.
    Despite Olsen’s valiant efforts to liken the circumstances
    here to those in Green, the comparison simply does not hold
    up. In Green, this court found it incontrovertible that the
    juror lied to conceal his criminal history, first in his juror
    questionnaire and then during voir dire. When called on to
    explain this behavior at a post-trial hearing, the juror gave
    explanations that were manifestly self-contradictory. Green,
    
    232 F.3d at 672
    . The juror also engaged in misconduct
    during the trial itself revealing his bias: it was alleged by
    other jurors that he said, during the proceedings, that he knew
    the defendant was guilty the moment he saw him and that he
    wished “the judge would let him go back to his place so he
    could get his piece” and shoot the defendant. 
    Id.
     at 673–74.
    When questioned about these allegations at the hearing, the
    juror offered “a variety of responses” that, again, were
    transparently self-contradictory and also conflicted with
    statements he had made in a declaration. 
    Id.
    Here, we think that one could fairly question the
    plausibility of Leavitt’s explanations for the omissions in his
    juror questionnaire. But these omissions and Leavitt’s
    explanations for them during the evidentiary hearing do not
    even approach the transparent lies of the juror in Green or the
    “misleading, contradictory, and outright false answers” that
    the juror later gave to explain those lies. Green, 
    232 F.3d at 678
    . The “pattern of lies, inappropriate behavior, and
    44                   UNITED STATES V . OLSEN
    attempts to cover up his behavior,” 
    id. at 676
    , by the juror in
    Green resulted in precisely the type of “extraordinary”
    situation where bias may be presumed as a matter of law. See
    Mitchell, 
    568 F.3d at 1151
    . Leavitt’s omissions in his juror
    questionnaire are not as clearly intentional, nor his later
    explanations as transparently false, as in that case or in
    Dyer.10 It is also worth noting that these omissions cannot
    have been motivated by a desire to pass judgment on Olsen,
    because Leavitt completed and mailed in the questionnaire
    over two weeks before he came to court and learned in which
    case he might be selected to serve as a juror.
    Because the facts before us, as developed in an
    evidentiary hearing by the district court, do not amount to the
    type of “extreme” situation in which manifest lies during voir
    dire justify a presumption of partiality, we do not find any
    implied bias here.
    3. McDonough Bias
    The third type of juror bias, “so-called McDonough-style
    bias,” occurs where a juror fails to answer honestly a material
    10
    The parallels that Olsen attempts to draw between his case and Green
    invariably crumble upon inspection. For instance, Leavitt failed to
    mention a misdemeanor trespass conviction that resulted in a fine; the
    Green juror failed to reveal a conviction for assault while he was in the
    Army that led him to spend six months in the brig. Green, 
    232 F.3d at 673, 676
    . Leavitt testified that he forgot about the trespassing incident,
    citing his rampant alcoholism during those years; the Green juror gave no
    explanation for his omission, and the trial court’s supposition that he
    forgot about it was an “unsupported assertion” not backed by “any
    evidence.” 
    Id. at 676
    . Significantly, the court in Green observed that if
    the juror in question had testified that he forgot about his assault
    conviction, the trial court’s finding might have been reasonable, “at least
    enough to avoid clear error.” Green, 
    232 F.3d at 676
    .
    UNITED STATES V . OLSEN                    45
    question on voir dire and “‘a correct response would have
    provided a valid basis for a challenge for cause.’” Fields,
    
    503 F.3d at
    766–67 (quoting McDonough Power Equipment,
    Inc., 
    464 U.S. at 556
    ). The only voir dire responses from
    juror Leavitt that conceivably would have justified a for-
    cause challenge are his answers regarding his prior
    knowledge of and opinions about the case. We have upheld
    the district court’s finding that Leavitt did not in fact answer
    these questions dishonestly, and accordingly no basis exists
    for a McDonough challenge.
    Because we also have affirmed the district court’s finding
    that Leavitt was not actually biased and have concluded that
    bias cannot be presumed in the circumstances of this case, we
    reject Olsen’s claim that juror misconduct denied him a fair
    trial.
    VI. Cumulative Error
    Finally, Olsen contends that the cumulative effect of
    errors at his trial violated due process by rendering the trial
    fundamentally unfair. Olsen cites three alleged errors: (1) an
    erroneous jury instruction, (2) the prosecutor’s use of guilt-
    assuming hypothetical questions, and (3) the suppression of
    the Melnikoff-related Brady material.
    Olsen did not raise the jury instruction issue on direct
    appeal and has not attempted to establish cause or prejudice
    excusing this failure; he appears to concede that the claim is
    procedurally barred. See United States v. Mejia-Mesa,
    
    153 F.3d 925
    , 929 (9th Cir. 1998). Even were it not, Olsen
    has given us no reason to believe that there is any merit
    whatsoever to this claim, which asks us to assume without
    46                UNITED STATES V . OLSEN
    any evidence that the jury adopted a strained
    misinterpretation of one of the court’s instructions.
    With respect to the prosecutor’s use of guilt-assuming
    hypothetical questions, a similar version of this claim was
    raised and rejected on direct review. This court held that any
    error in permitting such questions was cured by the limiting
    instruction the district court later gave to the jurors, advising
    them to disregard the questions asked of specific witnesses
    that assumed the defendant possessed certain items or
    searched the internet for particular subjects. Olsen, 120 F.
    App’x at 20.
    Apart from the curative effect of this limiting instruction,
    Olsen has not persuaded us that these allegedly guilt-
    assuming questions elicited answers from the witnesses that
    affected his substantial rights or damaged his case in any
    significant way. See United States v. Shwayder, 
    312 F.3d 1109
    , 1121 (9th Cir. 2002) (acknowledging trial court’s error
    in allowing guilt-assuming hypothetical questions but
    examining whether the answers to these questions were
    harmful to the defense).
    The district court judge, even while agreeing to give the
    limiting instruction, observed that in his recollection all of
    Olsen’s character witnesses said that their favorable opinion
    of him was not changed by the information with which the
    prosecutor confronted them. In one of the examples from the
    record that Olsen provides, the prosecutor asked of a
    character witness who had described Olsen as a peaceful
    person: “If somebody harmed somebody, is he a peaceful
    person?” The witness responded: “Depending on their intent
    and also I would have to say on a superficial level, that if
    somebody harmed somebody, they are not a peaceful person.”
    UNITED STATES V . OLSEN                   47
    It is readily apparent that any damaging effect such an
    abstract question and response could have had would be
    minimal, especially since Olsen was not accused in this case
    of having actually harmed anyone. In the other three
    examples Olsen provides, witnesses simply acknowledged
    that they did not know about the items found in Olsen’s
    cubicle or the internet research on poisons that he conducted.
    Whether considered alone or in combination with the
    remaining error that Olsen cites — the government’s failure
    to disclose Brady material about Arnold Melnikoff — any
    error in allowing these questions did not render Olsen’s trial
    fundamentally unfair or violate his due process rights.
    AFFIRMED.
