    A jury convicted Wesley Purkey of the kidnapping, rape, and murder of
    Jennifer Long, and sentenced him to death. See 
    18 U.S.C. §§ 1201
    (a), (g), 3559(d),
    3591-3598. On appeal, Mr. Purkey raises myriad challenges to his conviction and
    sentence. After careful review, we conclude that his arguments lack merit and
    therefore affirm the judgment of the district court.1
    1
    The Honorable Fernando J. Gaitan, Jr., United States District Judge for the
    Western District of Missouri.
    Jennifer Long, a sixteen year-old high school sophomore, disappeared in
    January of 1998. On December 15, 1998, while in the Wyandotte County Jail
    awaiting a Kansas state prosecution for the murder of eighty-year-old Mary Ruth
    Bales, Mr. Purkey contacted Detective Bill Howard of the Kansas City, Kansas, Police
    Department and offered to speak with him about a kidnapping and homicide that had
    occurred earlier that year. Mr. Purkey told Detective Howard that he also wanted to
    speak with an FBI agent about this crime because he wanted to spend his time in a
    federal, rather than a state, institution. Detective Howard asked FBI Special Agent
    Dirk Tarpley to go with him to meet with Mr. Purkey.
    The next day, Mr. Purkey met with Detective Howard and Agent Tarpley. At
    the beginning of the meeting, Mr. Purkey executed a form indicating that he
    understood and voluntarily waived his constitutional rights. He then told the officers
    that he was going to plead guilty in the Kansas case and was therefore willing to
    confess to the kidnapping, rape, and murder of a Missouri woman, provided that he
    could serve his state time in a federal penitentiary. Detective Howard and Agent
    Tarpley informed Mr. Purkey that they could not make any promises but would take
    whatever he had to say to the United States Attorney. After giving an account of the
    kidnapping, rape, and murder of the victim (who was later identified as Ms. Long),
    Mr. Purkey refused to cooperate further unless he received assurances from the United
    States Attorney that his case would be federally prosecuted.
    That afternoon, Detective Howard and Agent Tarpley met with Kurt Shernuk,
    an Assistant United States Attorney for the District of Kansas. Although he was
    skeptical of Mr. Purkey, Mr. Shernuk indicated that his office might be willing to
    prosecute the case if Mr. Purkey fully cooperated with the investigators and provided
    the location of the victim's remains and other evidence to corroborate his confession.
    After meeting with Mr. Shernuk, Detective Howard and Agent Tarpley returned
    to the Wyandotte County Jail to speak with Mr. Purkey. They told him that
    -2-
    Mr. Shernuk wanted a body and would require full cooperation, but they did not make
    Mr. Purkey any promises as to the sentence that he might receive. Mr. Purkey then
    led Messrs. Tarpley and Howard to the crime scene and to the place where he claimed
    to have discarded the victim's undergarments and jaw bone. He told the officers that
    because he had taken extraordinary measures to dispose of the body, including
    dismembering it with a chain saw and burning the remains, the victim's remains were
    not recoverable.
    More meetings occurred over the next several days. On December 17,
    Detective Howard and Agent Tarpley again met with Mr. Purkey and, after being
    reminded verbally of his constitutional rights, Mr. Purkey gave a detailed handwritten
    confession. The next day, Detective Howard met with Mr. Purkey and, after
    reminding him of his rights, conducted a photo lineup to see if he could identify the
    victim. Without hesitation, Mr. Purkey identified Ms. Long. Agent Tarpley met with
    Mr. Purkey three days later, and after being advised of his rights, Mr. Purkey
    confessed again.
    During the guilt phase of his federal trial, Mr. Purkey affirmed his statements
    about the killing and dismemberment of Ms. Long, but he disavowed his previous
    statements that he forced Ms. Long to travel with him from Missouri to his home in
    Kansas. Instead, he stated that Ms. Long, who he said he thought was a prostitute,
    voluntarily entered his truck and accompanied him to his home. He indicated that he
    fabricated the kidnapping aspect of the confession to ensure that his actions would be
    considered, and therefore prosecuted as, a federal crime. After deliberating briefly,
    the jury returned a verdict of guilty.
    During the penalty phase of the trial, the defense submitted and the court
    instructed on twenty-seven mitigating factors. Mr. Purkey's primary mitigation
    defense consisted of expert testimony indicating that he suffered brain damage that
    resulted in diminished mental capacity. The government presented expert testimony
    -3-
    to rebut this assertion and also produced evidence in support of six statutory and four
    non-statutory aggravating factors.
    After deliberating for eleven hours and ten minutes, the jury found the existence
    of all six of the statutory aggravating factors: (1) that the death of Ms. Long occurred
    during the commission and attempted commission of her kidnapping; (2) that
    Mr. Purkey killed Ms. Long in an especially heinous, cruel, and depraved manner in
    that the killing involved torture and serious physical abuse; (3) that the victim was
    particularly vulnerable due to her youthful age of sixteen years; (4) that Mr. Purkey
    had previously been convicted of an offense punishable by a term of imprisonment of
    more than one year, involving the use, attempted use, and threatened use of a firearm
    against another person; (5) that Mr. Purkey had previously been convicted of an
    offense resulting in the death of a person for which a sentence of life imprisonment
    was authorized by statute; and (6) that Mr. Purkey had previously been convicted of
    two or more offenses punishable by a term of imprisonment of more than one year,
    committed on different occasions and involving the infliction and attempted infliction
    of serious bodily injury and death upon another person. The jury also found the
    existence of three of the four non-statutory aggravating factors: (1) that the
    government established loss and harm because of the victim's personal characteristics
    as an individual human being and the impact of the death upon the victim's family; (2)
    that the defendant had previously killed Mary Ruth Bales in a vicious manner in that
    he repeatedly struck her in the head with a hammer until she died; and (3) that
    Mr. Purkey had a substantial criminal history. The jury did not record any evidence
    of its findings with regard to the mitigating factors. It then determined that
    Mr. Purkey should be sentenced to death.
    I.
    We begin with Mr. Purkey's arguments pertaining to the district court's denials
    of his pretrial motions.
    -4-
    A.
    Mr. Purkey's primary argument on appeal is that the district court erred in
    denying his motion to suppress his multiple confessions to the kidnapping, rape, and
    murder of Ms. Long. He argues that the district court should have suppressed his
    statements to Messrs. Tarpley and Howard because the statements were involuntary
    and therefore obtained in violation of the fifth amendment to the Constitution. He
    bases this argument on his assertion that the officers obtained the confessions through
    a false promise, cf. United States v. Pierce, 
    152 F.3d 808
    , 812-13 (8th Cir. 1998),
    namely, that if he cooperated with the government he would receive a life sentence in
    a federal institution. As an alternative to suppression, Mr. Purkey moved to prohibit
    the government from pursuing the death penalty. The district court also denied that
    motion.
    The core of Mr. Purkey's argument is that Detective Howard and Agent Tarpley
    procured his confession by indicating that the Assistant United States Attorney had
    accepted Mr. Purkey's alleged quid pro quo offer, that is, that Mr. Purkey would
    confess to the crime and provide full cooperation in return for a life sentence in a
    federal institution. Detective Howard and Agent Tarpley testified at the suppression
    hearing that they never made this representation to Mr. Purkey. The district court,
    adopting the discussion and conclusions in the report and recommendation of a
    magistrate judge,2 squarely rejected Mr. Purkey's version of the events. It found that,
    "[d]uring all of the time the officers spent with Purkey on December 16, 1998, there
    were no hints or suggestions made to Purkey ... that Purkey would get a life sentence
    if he confessed. No one told Purkey that a life sentence would be recommended if he
    confessed." The court inserted a footnote within this language to make explicit that
    it found "the testimony of Special Agent Tarpley and Detective Howard more credible
    than that of defendant Purkey" on the issue of whether Messrs. Tarpley and Howard
    2
    The Honorable Sarah W. Hays, United States Magistrate Judge for the Western
    District of Missouri.
    -5-
    told Mr. Purkey that the Assistant United States Attorney had agreed to give
    Mr. Purkey a life sentence in the federal system in exchange for a full confession.
    Finally, the court concluded that during the course of the investigation, "[n]o promises
    were made to defendant Purkey in exchange for his confessions. While the defendant
    was apparently surprised to find out that the death penalty was a potential sentence he
    might receive, the officers did not mislead [the] defendant into believing that there
    was no federal death penalty."
    Because Mr. Purkey's challenges are to the district court's conclusions regarding
    the facts underlying its decisions to deny his motions, we review the matter for clear
    error. See United States v. Kilgore, 
    58 F.3d 350
    , 353 (8th Cir. 1995); see also United
    States v. Heath, 
    58 F.3d 1271
    , 1275 (8th Cir. 1995), cert. denied, 
    516 U.S. 892
     (1995).
    After a thorough review of the record, we cannot conclude that the district court
    clearly erred in arriving at the credibility determinations and factual conclusions that
    it reached. We therefore affirm the district court's denial of Mr. Purkey's motion to
    suppress his statements and his motion to prohibit the government from seeking the
    death penalty.
    B.
    Mr. Purkey also maintains that the district court erred when it denied his motion
    to dismiss based on the alleged destruction of notes that Mr. Purkey asserts that he
    took to document his conversations with Detective Howard and Agent Tarpley in
    December of 1998. Mr. Purkey testified that these notes were destroyed by prison
    staff during a "shakedown" of his segregation pod while he was incarcerated at
    CCA(Corrections Corporation of America)-Leavenworth. He asserts that the
    destruction of these notes constitutes a denial of due process and requires dismissal
    of the indictment.
    In United States v. Malbrough, 
    922 F.2d 458
     (8th Cir. 1990), cert. denied,
    
    501 U.S. 1258
     (1991), we recognized that the "Supreme Court has held that the state's
    -6-
    failure to preserve evidence does not constitute a denial of due process unless ...
    comparable exculpatory evidence was not reasonably available to the defendant." 
    Id.
    at 463 (citing California v. Trombetta, 
    467 U.S. 479
    , 488-89 (1984)). The district
    court, adopting the discussion and conclusions of the magistrate judge, concluded that
    Mr. Purkey's motion must fail because, among other shortcomings, Mr. Purkey could
    not demonstrate that he was unable to obtain comparable exculpatory evidence by
    other means. We review the matter to determine whether this conclusion was clearly
    erroneous, cf. United States v. Weise, 
    89 F.3d 502
    , 504 (8th Cir. 1996), and we
    conclude that it was not.
    At best, these notes can be characterized as Mr. Purkey's account of his
    conversations with Detective Howard and Agent Tarpley. They were neither
    transcripts of the conversations nor were they attested to by Messrs. Howard or
    Tarpley. They were simply Mr. Purkey's recollections of the conversations as
    recorded shortly after each conversation concluded. Mr. Purkey had ample
    opportunity to introduce comparable evidence in the form of his own testimony as to
    the substance of the conversations. And, although these notes could have been read
    into evidence to fill gaps in Mr. Purkey's recollection as to the content of those
    conversations, see Fed. R. Evid. 803(5), Mr. Purkey's own testimony belied his
    assertion of an incomplete recollection of the conversations. We can find no clear
    error in the magistrate judge's observation that, "Despite Purkey's contention that he
    needs these notes to assist him with remembering the details of the interrogations,
    Purkey's testimony would suggest that he has no trouble remembering [those] details
    ... (at least until defense counsel reminded him that he should not remember)." Hence
    the district court did not err in denying Mr. Purkey's motion to dismiss based on the
    alleged destruction of his notes.
    C.
    Mr. Purkey also argues that the district court erred in denying his pretrial
    motion asking the court to prohibit the government from seeking the death penalty
    -7-
    because of two violations of the fifth amendment's indictment clause. First,
    Mr. Purkey asserts that the Federal Death Penalty Act (FDPA), 
    18 U.S.C. § 3591
    -
    3598, is facially unconstitutional because it vests the prosecution with unilateral
    authority to seek the death penalty without ever taking the matter of whether the death
    penalty is justified to the grand jury, see 
    18 U.S.C. § 3593
    (a). Second, he argues that
    his prosecution ran afoul of the indictment clause because the government failed to
    seek an indictment upon some of the necessary elements of the capital prosecution,
    namely, the government's non-statutory aggravating factors and the issue of whether
    the aggravating factors sufficiently outweighed any mitigating factors to justify a
    sentence of death. Both of these are questions of law, and we therefore review them
    de novo. See United States v. Koons, 
    300 F.3d 985
    , 990 (8th Cir. 2002); cf. United
    States v. Roy, 
    408 F.3d 484
    , 491 (8th Cir. 2005).
    In United States v. Allen, 
    406 F.3d 940
    , 949 (8th Cir. 2005) (en banc), we
    addressed the same facial challenge that Mr. Purkey now presents. There we
    recognized that the FDPA does vest the prosecution with authority to charge
    aggravating factors in a notice of intent to seek the death penalty, and does not
    specifically require the government to bring those factors before the grand jury for
    inclusion in the indictment. But because "nothing in the Act precludes the
    government from also submitting them to the grand jury for inclusion in the
    indictment," we rejected the contention that the FDPA was unconstitutional. 
    Id.
    Therefore, Mr. Purkey's facial challenge also fails.
    To deal with Mr. Purkey's second challenge, we begin with a bit of background.
    Under the FDPA, once the jury finds the defendant guilty of one of the offenses listed
    in 
    18 U.S.C. § 3591
    , the trial proceeds to a separate phase – the sentencing or penalty
    phase. In a homicide case, the jury must make three determinations in this latter phase
    before it can impose the death penalty: First it must find, unanimously and beyond
    a reasonable doubt, that the defendant acted with the requisite mens rea. See
    
    18 U.S.C. § 3591
    (a)(2). Second, again unanimously and beyond a reasonable doubt,
    -8-
    it must find the existence of at least one statutory aggravating factor. See 
    18 U.S.C. §§ 3592
    (c), 3593(d). If the above two requirements are satisfied, the jury must then
    determine whether the aggravating factors, both statutory and non-statutory,
    "sufficiently outweigh" the mitigating factors presented by the defendant to justify a
    death sentence, "or, in the absence of a mitigating factor, whether the aggravating
    factor or factors alone are sufficient to justify" that sentence. See 
    18 U.S.C. § 3593
    (e).
    Mr. Purkey maintains that because the jury is required to take this third step
    before it may impose a sentence of death, the necessary elements for a capital
    prosecution under the FDPA include all aggravating factors, including non-statutory
    aggravating factors, and the weighing of aggravating factors versus mitigating factors.
    He therefore contends that because his superseding indictment did not include non-
    statutory aggravating factors or a determination that there exists probable cause to
    believe that aggravating factors sufficiently outweigh mitigating factors so as to
    justify a sentence of death, it falls short of what the fifth amendment requires. We
    disagree.
    "[T]he same facts that the Sixth Amendment requires to be proven to the petit
    jury beyond a reasonable doubt in state and federal prosecutions must also be found
    by the grand jury and charged in the indictment in federal prosecutions." Allen,
    
    406 F.3d at 943
    . For that reason, Allen held that to comport with the fifth amendment
    "at least one statutory aggravating factor and the mens rea requirement [must] be
    found by the grand jury and charged in the indictment" in a prosecution under the
    FDPA. 
    Id.
     Mr. Purkey's superseding indictment satisfies both of these requirements.
    The indictment must charge at least one of the statutory aggravating factors that
    is ultimately found by the petit jury because "that is what is required to elevate the
    available statutory maximum sentence from life imprisonment to death." 
    Id.
     In other
    words, including that factor in the indictment is required to make the defendant
    eligible for the death penalty. See United States v. Higgs, 
    353 F.3d 281
    , 299 (4th Cir.
    -9-
    2003), cert. denied, 
    125 S. Ct. 608
     (2004). We now make clear what Allen merely
    implied: "There is no requirement that the indictment allege all of the factors that
    might be weighed by the jury when deciding whether to impose a death sentence."
    Higgs, 
    353 F.3d at 299
    . Non-statutory aggravating factors do not increase the
    maximum punishment to which a defendant is subject. They are neither sufficient nor
    necessary under the FDPA for a sentence of death. Their purpose is merely to aid the
    sentencer "in selecting the appropriate sentence from the available options," 
    id. at 298
    ,
    " 'on the basis of the character of the [defendant] and the circumstances of the crime,'
    " 
    id.
     (quoting Tuilaepa v. California, 
    512 U.S. 967
    , 972 (1994)).
    Further, it makes no sense to speak of the weighing process mandated by
    
    18 U.S.C. § 3593
    (e) as an elemental fact for which a grand jury must find probable
    cause. In the words of the statute, it is a "consideration," 
    18 U.S.C. § 3593
    (e), – that
    is, the lens through which the jury must focus the facts that it has found to produce an
    individualized determination regarding "whether the defendant should be sentenced
    to death, to life imprisonment without possibility of release or some other lesser
    sentence." 
    Id.
    We thus conclude that Mr. Purkey's arguments based on the indictment clause
    of the fifth amendment are without merit.
    II.
    Mr. Purkey next challenges the district court's for-cause exclusion of three
    potential jurors who expressed reluctance to impose the death penalty. In Wainwright
    v. Witt, 
    469 U.S. 412
    , 420, 424 (1985), the Supreme Court instructed that a potential
    juror may be excluded for cause based on his or her views on capital punishment only
    if those views would " ' prevent or substantially impair the performance of his duties
    as a juror in accordance with his instructions and his oath. ' " (quoting Adams v. Texas,
    
    448 U.S. 38
    , 45 (1980)). We review a district court's removal of death-scrupled
    venirepersons for an abuse of discretion. See United States v. Nelson, 
    347 F.3d 701
    ,
    710-11 (8th Cir. 2003), cert. denied, 
    125 S. Ct. 486
     (2004); United States v. Ortiz,
    -10-
    
    315 F.3d 873
    , 888 (8th Cir. 2002), cert. denied, 
    538 U.S. 1042
     & 
    540 U.S. 1073
    (2003).
    Mr. Purkey first asks us to find error in the district court's removal of Margaret
    Fox. He begins by inviting us to adopt the holding of the Tenth Circuit in United
    States v. Chanthadara, 
    230 F.3d 1237
    , 1270 (10th Cir. 2000), cert. denied, 
    534 U.S. 992
     (2001), and review Ms. Fox's removal de novo because the court struck her solely
    on the basis of her answers to a questionnaire. We do not agree, however, with
    Chanthadara's implicit assumption that a district court's decision on the qualifications
    of a juror is entitled to deference only because of that court's superior position to
    assess a potential juror's demeanor and credibility. See 
    id. at 1269-70
    . Other reasons,
    such as respect for the trial process, "the expertise developed by trial judges," and the
    desire to conserve judicial resources also underpin the fundamental principle that
    "appellate courts are not to decide factual questions de novo, reversing any findings
    they would have made differently." Maine v. Taylor, 
    477 U.S. 131
    , 145 (1986); cf.
    Anderson v. Bessemer City, 
    470 U.S. 564
    , 574-76 (1985); Fed. R. Civ. P. 52(a).
    Accordingly, we decline this invitation to stray from the standard of review
    established in our previous cases, which is whether the district court abused its
    discretion.
    The district court did not abuse its discretion by striking Ms. Fox. She
    repeatedly indicated on the questionnaire that she had serious reservations about
    capital punishment. When asked in question thirty-eight of the questionnaire to
    describe her feelings about the death penalty, how strong those feelings were, and how
    long she had held them, she wrote, "Within the last 50 years I've gained stronger and
    stronger feelings against [the] use of the death penalty. I believe major criminals
    should be punished, but taking away their lives should be left to God." Her responses
    to questions thirty-six and thirty-seven, which asked about the effect that exposure to
    books, articles, and movies about the death penalty had on her, also indicate that she
    -11-
    "questioned that the death penalty should be used" and "question[ed] the right of the
    courts to administer the death penalty."
    Question thirty-nine, a multiple choice question, gave each juror an opportunity
    to mark the choice that best described his or her feelings about the death penalty.
    Three of the eight choices pertained to people with some degree of opposition to the
    death penalty. They were as follows:
    a. I am opposed to the death penalty, and I will never vote
    to impose the death penalty in any case, no matter what the
    facts.
    b. I am opposed to the death penalty, and I would have a
    difficult time voting to impose the death penalty.
    c. I am opposed to the death penalty, but could vote to
    impose the death penalty if I believed that the death penalty
    was called for in light of the facts and law in the case.
    Ms. Fox declined to indicate that she could vote to impose the death penalty by
    selecting choice "c" and instead chose the ambiguous "b." When we consider this
    response together with her other answers regarding her views on the death penalty, we
    find sufficient evidence in the record from which the district court could conclude that
    her views on the death penalty would " 'substantially impair the performance of her
    duties as a juror in accordance with h[er] instructions and h[er] oath.' " Wainwright,
    
    469 U.S. at 424
     (quoting Adams, 
    448 U.S. at 45
    ).
    Mr. Purkey also argues that the court erroneously struck Willie Randle after
    mishearing or incorrectly recollecting his responses during voir dire. During voir dire,
    the government asked Mr. Randle whether he would "hold the government to a higher
    -12-
    burden of proof than what is required under the law." He responded, "I think I
    would." When the government next asked whether he would hold it to a higher
    burden of proof than "beyond a reasonable doubt" he replied, "It has to be proof
    without a reasonable doubt." Later, in granting the government's request to strike
    Mr. Randle, the district judge declared, "My recollection is that he's holding the
    government to a higher standard than the law provides."
    Reviewing the cold record, it is difficult to divine exactly what Mr. Randle
    meant when he replied that "[i]t has to be proof without a reasonable doubt." Although
    those words of the transcript, taken literally, may indicate that Mr. Randle had agreed
    to apply a burden equivalent to the one that the law actually imposes, the transcript
    cannot provide any insight regarding Mr. Randle's intent in using the phrase "without
    a reasonable doubt" instead of "beyond a reasonable doubt." This is why the Supreme
    Court instructed in Wainwright, 
    469 U.S. at 426
    , that "deference must be paid to the
    trial judge who sees and hears the juror." The trial judge, who had the opportunity to
    observe the exchange, could have reasonably interpreted Mr. Randle's refusal to parrot
    the words of the government and instead use the phrase "without a reasonable doubt"
    as an affirmation of his earlier statement that he would hold the government to a
    higher burden of proof than the law provides. Based on the colloquy between Mr.
    Randle and the government, as well as the court's stated reason for its ruling, we
    conclude that the district court did not abuse its discretion by striking this potential
    juror.
    Finally, Mr. Purkey argues that the district court erred when it removed Gary
    Danford for cause after he had been "rehabilitated." When questioned by the
    government, Mr. Danford insisted that he would hold the government to a higher
    burden of proof than reasonable doubt. But Mr. Danford reversed course under
    subsequent questioning by Mr. Purkey's counsel and indicated that he would "follow
    the law." The district court concluded that, "I think he has kind of made up his mind
    what the standard is and that the standard he has decided upon is something different
    -13-
    than what the law provides." Quite simply, the district court made a reasonable
    judgment based on its impression of Mr. Danford's credibility as was its prerogative.
    See Nelson, 
    347 F.3d at 710-11
    ; United States v. Moore, 
    149 F.3d 773
    , 779-80 (8th
    Cir. 1998), cert. denied, 
    525 U.S. 1030
     & 1082 (1998). The record lacks adequate
    grounds for us to conclude that the district court abused its discretion.
    III.
    Mr. Purkey also maintains that the district court erred in several respects during
    the guilt phase of his trial.
    A.
    We begin with Mr. Purkey's contention that the district court erred by refusing
    to allow certain evidence during the guilt phase of the trial. He asserts that the district
    court erred in the following ways: by excluding the testimony of defense expert
    Dr. David Preston; by refusing to allow Mr. Purkey to testify about how his father had
    introduced him to prostitutes at an early age; and by refusing to permit cross-
    examination of Michael Speakman regarding his misconduct while he was
    incarcerated at CCA-Leavenworth. "We review de novo the district court's
    interpretation and application of the rules of evidence, and review for an abuse of
    discretion the factual findings supporting its evidentiary ruling." United States v.
    Smith, 
    383 F.3d 700
    , 706 (8th Cir. 2004). We may affirm on any ground supported
    by the record, even if that ground was not relied on by the district court. See Bilal v.
    Lockhart, 
    993 F.2d 643
    , 645 (8th Cir. 1993), cert. denied, 
    510 U.S. 924
     (1993).
    Dr. Preston, a nuclear medicine specialist, conducted positron emission
    topography and magnetic resonance imaging testing upon Mr. Purkey and would have
    testified that those tests revealed abnormalities within Mr. Purkey's brain. Mr. Purkey
    intended to offer this testimony during the guilt phase of the trial to support both his
    contention that he did not intentionally kidnap Ms. Long (because he thought she was
    a prostitute and/or voluntarily accompanied him to his home) and to illuminate
    -14-
    Mr. Purkey's state of mind when he confessed to Detective Howard and Agent
    Tarpley. The district court concluded that "although Dr. Preston is qualified in the
    field of nuclear medicine, he is not qualified to testify regarding defendant's state of
    mind and actions at the time of the offenses or at the time that Mr. Purkey gave his
    statements to the investigators."
    We believe that the district court's conclusion was correct. Although we harbor
    no doubt that Dr. Preston was qualified to testify regarding the results of the tests that
    he conducted on Mr. Purkey, there is nothing in the record that indicates that he was
    qualified to connect that testimony to the inquiry for which it was offered, namely,
    Mr. Purkey's state of mind and actions either at the time of the offenses or when he
    gave his statements to the investigators. Indeed, in neither the expert report nor the
    offer of proof did Dr. Preston even attempt to tie the test results to Mr. Purkey's state
    of mind on the specific occasions in question. When questioned by the government,
    moreover, Dr. Preston admitted that the images produced by the tests could not predict
    behavior and did not have a causal relationship to criminal behavior. There is
    manifestly no error in the district court's decision to exclude Dr. Preston's testimony.
    Mr. Purkey also argues that the court erred when it refused, in the guilt phase
    of the trial, to allow him to testify that his father had introduced him to the use of
    prostitutes during his boyhood. (The court did permit some testimony of this nature
    in the penalty phase.) Mr. Purkey submits that this testimony would have provided
    the jury with context to understand why he might have mistakenly believed that
    Ms. Long was a prostitute. This, he argues, would have bolstered his defense that he
    did not kidnap Ms. Long and that she willingly entered his car and traveled with him
    from Missouri to Kansas. And, defense counsel argues, if the jury believed that
    Mr. Purkey did not transport Ms. Long across state lines against her will and did not
    do so with the intent to rape her, it could not have convicted him of kidnapping. But
    we fail to see how the method by which Mr. Purkey was introduced to prostitutes
    more than thirty years before his crime is relevant to explaining why he mistook a
    -15-
    teenage schoolgirl for a prostitute, and we therefore uphold the district court's decision
    to exclude the testimony.
    Mr. Purkey also argues that the district court erred by refusing to permit him to
    cross-examine Michael Speakman regarding Mr. Speakman's uncharged misconduct
    while at CCA-Leavenworth. Mr. Purkey wanted to elicit this testimony to
    demonstrate that a desire to avoid punishment for these uncharged acts might have
    motivated Mr. Speakman to provide information and testimony for the prosecution.
    He asserts that this denial deprived him of his sixth amendment right to confront an
    adverse witness.
    Mr. Purkey calls our attention to the Supreme Court's language in Davis v.
    Alaska, 
    415 U.S. 308
    , 316-17 (1974), which recognizes that "the exposure of a
    witness' motivation in testifying is a proper and important function of the
    constitutionally protected right of cross-examination.” 
    Id. at 316-17
    . But this passage
    does not suggest that a judge should be prevented from imposing limits of any sort on
    defense counsel's inquiry into the potential bias of a prosecution witness. Delaware
    v. Van Arsdall, 
    475 U.S. 673
    , 679 (1986). "On the contrary, trial judges retain wide
    latitude ... to impose reasonable limits on such cross-examination based on concerns
    about, among other things, harassment, prejudice, confusion of the issues, the witness'
    safety, or interrogation that is repetitive or only marginally relevant." 
    Id.
     We will not
    reverse a trial court's decision to limit cross-examination absent a "clear abuse of
    discretion and a showing of prejudice to [the] defendant." United States v. Love,
    
    329 F.3d 981
    , 984 (8th Cir. 2003).
    Mr. Purkey has failed to demonstrate a violation of the confrontation clause.
    To do so, he must show that a reasonable jury might have received a different
    impression of the witness's credibility had Mr. Purkey's counsel been permitted to
    pursue his proposed line of cross-examination. See Van Arsdall, 
    475 U.S. at 680
    ;
    United States v. Drapeau, 
    414 F.3d 869
    , 875-76 (8th Cir. 2005). Here, Mr. Purkey's
    -16-
    counsel conclusively demonstrated by other means that Mr. Speakman was driven to
    testify by a desire for leniency. Mr. Speakman's testimony established that the
    government had filed a motion under Federal Rule of Criminal Procedure 35,
    requesting a reduction of Mr. Speakman's sentence. Mr. Purkey's counsel asked
    Mr. Speakman, "Basically what you're trying to do is do your best to get a reduction
    to your sentence?" Mr. Speakman replied, "I'd be lying if I said I was sitting here
    being a good citizen." Mr. Purkey's counsel then asked, "Your sole point in being
    here is to reduce the sentence that you received?" Mr. Speakman replied, "Yes,
    ma'am." We have difficulty imagining how further testimony could have shown more
    definitively that a desire for leniency played a significant part in Mr. Speakman's
    willingness to testify. Consequently, the district court did not abuse its discretion in
    limiting cross-examination that would have further established that point.
    B.
    Mr. Purkey also submits that the district court incorrectly instructed the jury on
    the elements contained in the kidnapping statute. See 
    18 U.S.C. § 1201
    . That statute
    provides that a person commits the offense of kidnapping if he or she "unlawfully
    seizes, confines, inveigles, decoys, kidnaps, abducts, or carries away and holds for
    ransom or reward or otherwise any person ... when – (1) the person is willfully
    transported in interstate or foreign commerce." 
    Id.
     This statute quite clearly requires
    that the government prove that Mr. Purkey seized Ms. Long "for ransom or reward or
    otherwise," 
    id.,
     which in this case was for the purpose of forcible rape. Mr. Purkey,
    however, contends that the statute also requires that the government prove that he
    transported Ms. Long across state lines for that same reason. He bases this contention
    on the language of the statute that requires the defendant to have "willfully
    transported," 
    id.,
     his or her victim. He submits that this phrase requires that the
    kidnapper transport his or her victim with the intent to do something that the law
    forbids. Cf. United States v. Gabaldon, 
    389 F.3d 1090
    , 1094-95 n.1 (10th Cir. 2004),
    cert. denied, 
    125 S. Ct. 1688
     (2005). He therefore maintains that the district court
    erred by failing to give an instruction that required the government to prove not only
    -17-
    that he seized the victim for the purpose of forcible rape but also that he transported
    her across the state line for the purpose of forcible rape. This error is significant,
    according to Mr. Purkey, because he argued as part of his defense that he transported
    Ms. Long from Missouri to Kansas without the intent to rape. We will affirm if the
    instructions correctly stated the law and fairly and adequately submitted the issues to
    the jury. Cf. United States v. Kehoe, 
    310 F.3d 579
    , 593 (8th Cir. 2002), cert. denied,
    
    538 U.S. 1048
     (2003).
    The district court instructed the jury that in order to convict it had to find that
    "the defendant unlawfully seized, confined, kidnapped, abducted, carried away or held
    Jennifer Long;" that "the defendant did so for the purpose of the forcible rape of
    Jennifer Long;" that "the defendant willfully, knowingly, and unlawfully transported
    Jennifer Long across the state line from Missouri to Kansas;" and that "Jennifer Long
    died as a result of defendant's actions." This instruction precisely tracked the statute's
    ordering of the elements. See 
    18 U.S.C. § 1201
    . And, although the Eighth Circuit
    Manual of Model Jury Instructions (Criminal) (2005) does not contain a recommended
    instruction on kidnapping, the instruction given by the district court is consistent with
    the recommended instructions for the Ninth and Eleventh Circuit, see Ninth Circuit
    Manual of Model Jury Instructions (Criminal) § 8.95 (2003 ed.); Eleventh Circuit
    Pattern Jury Instructions (Criminal) 49 (2003 ed.), as well as the instruction
    recommended by the Federal Judicial Center, Pattern Criminal Jury Instructions § 84.
    Cf. Eighth Circuit Manual of Model Jury Instructions (Criminal) 12.07A. We disagree
    with Mr. Purkey's construction of the statute and therefore find no error in the district
    court's instruction on the elements contained in § 1201.
    -18-
    C.
    In his last contention of error with respect to the guilt phase of his trial,
    Mr. Purkey maintains that the district court erred in denying his motion for a mistrial
    based on prosecutorial misconduct. He asserts that the government's efforts to call
    attention to his tattoos that depicted, among other things, a Nazi swastika and symbols
    of the Aryan Brotherhood unfairly inflamed the jury and deprived him of his right to
    a fair trial.
    During the government's direct examination of its first witness, it displayed a
    picture of Mr. Purkey standing shirtless with his tattoos visible. Due to a
    misunderstanding between the prosecution and the defense, Mr. Purkey's counsel did
    not have a chance to object before the government displayed the picture to the jury.
    Mr. Purkey's counsel then objected to the picture's admission into evidence and that
    objection was sustained. Three days later, during the government's cross-examination
    of Mr. Purkey, the government again highlighted the tattoos. The prosecutor asked
    Mr. Purkey whether Ms. Long observed his tattoos, including the "Nazi swastika"
    tattoo, when she entered his vehicle or while she was, according to Mr. Purkey,
    voluntarily kissing him while he had his shirt off. The government stated that it made
    this inquiry to demonstrate the unreasonableness of Mr. Purkey's testimony that
    Ms. Long voluntarily accompanied him to his home and consented to engaging in
    foreplay with him. When defense counsel objected to this question, the district court
    sustained the objection and instructed the jury to disregard the government's questions
    about Mr. Purkey's tattoos. The defense then asked the judge to declare a mistrial
    based on the prosecution's referring to the tattoos after the district court had previously
    sustained the objection regarding the picture showing the tattoos. The district court
    denied that request.
    "The test for reversible prosecutorial misconduct has two parts: (1) the
    prosecutor's remarks or conduct must in fact have been improper, and (2) such
    -19-
    remarks or conduct must have prejudicially affected the defendant's substantial rights
    so as to deprive the defendant of a fair trial." United States v. Hernandez, 
    779 F.2d 456
    , 458 (8th Cir.1985). Even assuming arguendo that the prosecutor's actions and
    questions were improper, these actions nevertheless fail to constitute reversible error.
    When determining whether the prosecutor's remarks and conduct so infected the trial
    with unfairness that it deprived the defendant of a fair trial, we usually consider three
    criteria: "(1) the cumulative effect of such misconduct; (2) the strength of the properly
    admitted evidence of the defendant's guilt; and (3) the curative actions taken by the
    trial court." Hernandez, 779 F.2d at 460. Here the cumulative effect of the
    prosecutor's references to Mr. Purkey's tattoos was not significant. Although we do
    not doubt that references of this sort can sometimes result in prejudice, the prosecution
    referred to Mr. Purkey's tattoos only twice, cf. id., and only briefly at that. There was
    also considerable evidence of guilt. Although he gave a somewhat different story at
    trial, there was evidence that Mr. Purkey had confessed to the crime on multiple
    occasions. Finally, the district court took prompt curative action. It sustained the
    objections to the admission of the picture and to the questions regarding Mr. Purkey's
    tattoos. After sustaining the latter objection, the court also instructed the jury to
    disregard the questions. Cf. United States v. Uphoff, 
    232 F.3d 624
    , 625-26 (8th Cir.
    2000). We therefore reject Mr. Purkey's contention that his assertions of prosecutorial
    misconduct warrant reversal.
    IV.
    We move now to Mr. Purkey's assignments of error regarding the penalty phase
    of his trial.
    A.
    Mr. Purkey makes several arguments relating to the district court's evidentiary
    rulings. He asserts that the district court erred in the following ways: by refusing to
    permit evidence that his wife had poisoned him; by excluding the testimony of
    Dr. Mark Cunningham regarding Mr. Purkey's alleged fetal alcohol exposure; by
    -20-
    refusing to permit the surrebuttal testimony of Dr. Stephen Peterson in response to the
    testimony of Dr. Helen Mayberg; by limiting the impeachment of Dr. Park Dietz; and
    by allowing the government to question Dr. Peterson regarding his views on the death
    penalty.
    "The Federal Death Penalty Act (FDPA) erects very low barriers to the
    admission of evidence at capital sentencing hearings." United States v. Lee, 
    274 F.3d 485
    , 494 (8th Cir. 2001), cert. denied, 
    537 U.S. 1000
     (2002). In the sentencing phase,
    "[i]nformation is admissible regardless of its admissibility under the rules governing
    admission of evidence at criminal trials." See 
    18 U.S.C. § 3593
    (c). One reason for
    this more lenient standard is that it affords the defendant additional opportunities to
    present mitigating evidence consistent with the Supreme Court's directive that to meet
    constitutional requirements in capital cases " 'the sentencer ... not be precluded from
    considering, as a mitigating factor, any aspect of a defendant's character or record and
    any circumstances of the offense that the defendant proffers as a basis for a sentence
    less than death.' " Eddings v. Oklahoma, 
    455 U.S. 104
    , 110 (1982) (quoting Lockett
    v. Ohio, 
    438 U.S. 586
    , 604 (1978) (plurality opinion)) (emphasis omitted).
    But this does not mean that the defense has carte blanche to introduce any and
    all evidence that it wishes. The trial court retains its traditional authority "to exclude,
    as irrelevant, evidence not bearing on the defendant's character, prior record, or the
    circumstances of his offense." Lockett, 
    438 U.S. at
    604 n.12 (plurality opinion). The
    FDPA, moreover, invests the judge with the authority to exclude probative
    information during the penalty phase if "its probative value is outweighed by the
    danger of creating unfair prejudice, confusing the issues, or misleading the jury."
    
    18 U.S.C. § 3593
    (c). We review the record to determine whether the district judge
    abused the discretion entrusted to him by the FDPA, see United States v. Johnson,
    
    223 F.3d 665
    , 674 (7th Cir. 2000), cert. denied, 
    534 U.S. 829
     (2001); United States
    v. Hall, 
    152 F.3d 381
    , 397 (5th Cir. 1998), cert. denied, 
    526 U.S. 1117
     (1999),
    -21-
    abrogated on other grounds in United States v. Martinez-Salazar, 
    528 U.S. 304
    , 310-
    14 (2000), and we determine de novo the question of whether Mr. Purkey's
    constitutional rights have been violated. See United States v. Washington, 
    318 F.3d 845
    , 854-55 (8th Cir. 2003), cert. denied, 
    540 U.S. 884
     & 899 (2003). Even if we
    conclude that the district court erred, we cannot reverse or vacate a federal death
    sentence on account of an error that is harmless beyond a reasonable doubt. See
    
    18 U.S.C. § 3595
    (c)(2); Jones v. United States, 
    527 U.S. 373
    , 402-05 (1999).
    Mr. Purkey contends that the district court erred by refusing to allow evidence
    that his wife, Jeanette Purkey, had poisoned him. Mr. Purkey wished to use this
    evidence to demonstrate that because he was operating under the influence of poison
    when he murdered the elderly Kansas woman or when he killed Ms. Long, his actions
    took place while he was involuntarily intoxicated or, at the very least, in an altered
    mental state. When he sought to introduce the evidence in the penalty phase (he also
    sought to introduce this evidence in the guilt phase), he had no evidence that the
    poison he allegedly received, rat poison, had any known effect on the mind. Also, his
    wife's testimony as to whether she had poisoned him during the relevant time period
    was equivocal at best. During the penalty phase, the government objected to the
    evidence, asserting that for both of the above reasons the presentation of this evidence
    was not relevant and would be a "big diversion" for the jury. The district court
    agreed.
    We cannot say that the district court erred in excluding this evidence. The
    defense admitted that it had no evidence that rat poison has any psychological effects.
    Therefore, this evidence could not have had any probative value to suggest that
    Mr. Purkey's mind was operating under the poison's supposed influence when he
    committed either of the two murders. A reasonable judge could conclude that this
    evidence was both completely irrelevant to the purpose for which it was offered, cf.
    Lockett, 
    438 U.S. at
    604 n.12 (plurality opinion), and, because of the scandalous and
    -22-
    perplexing nature of the claim, had significant potential to confuse or mislead the jury.
    Cf. 
    18 U.S.C. § 3593
    (c).
    Mr. Purkey also asserts on appeal that this evidence also demonstrates his
    difficult home life. Because he did not argue this below, we review for plain error,
    see Lee, 
    274 F.3d at 493
    ; United States v. Turner, 
    104 F.3d 217
    , 221 (8th Cir. 1997),
    and find none. To begin, we note Ms. Purkey's benevolent, if misguided, motivation
    for poisoning her husband by mixing the poison with his drugs: She asserted that she
    was trying to scare him into abandoning his illegal use of drugs. This evidence might
    demonstrate that Mr. Purkey had someone in his life who cared about his well being.
    To the extent that this evidence could be construed as illustrating Mr. Purkey's
    difficult home life, we note that the record is replete with evidence of the difficult and
    dysfunctional environments in which Mr. Purkey has lived, and so we cannot
    conclude that the omission of this additional evidence affected his substantial rights.
    See Turner, 
    104 F.3d at 221
    .
    Mr. Purkey also contends that the district court erred by refusing to allow
    Dr. Cunningham to testify to his opinion that Mr. Purkey suffered from fetal alcohol
    exposure. The district court excluded the evidence because Mr. Purkey could not
    adduce specific evidence that his mother drank during the time that she was pregnant
    with him. Mr. Purkey's offer of proof does indicate, however, that had the court
    permitted Dr. Cunningham to testify on this issue he would have brought forth
    significant circumstantial evidence that Mr. Purkey suffered from this affliction. First,
    there was evidence that Mr. Purkey's mother abused alcohol dating back to at least
    1950. (Mr. Purkey was born in 1952.) Second, there was evidence that Mr. Purkey's
    mother had two other children around the time of Mr. Purkey's birth, both of whom
    died, one shortly before and one shortly after birth. This, according to
    Dr. Cunningham, would have been consistent with those children's fetal alcohol
    exposure. Third, Dr. Cunningham would have testified that Mr. Purkey's brain
    -23-
    condition is consistent with his having suffered fetal alcohol exposure. We think that
    Dr. Cunningham's testimony regarding Mr. Purkey's fetal alcohol exposure would
    have provided probative mitigating evidence. Cf. Silva v. Woodford, 
    279 F.3d 825
    ,
    847 n.17 (9th Cir. 2002), cert. denied, 
    537 U.S. 942
     (2002). Given that and the
    relaxed standard set forth by 
    18 U.S.C. § 3593
    (c), we conclude that the district court
    erred when it excluded this evidence simply because there was no direct evidence that
    Mr. Purkey's mother drank while pregnant with him.
    Nevertheless, when we consider the record as a whole, we are satisfied that this
    error was harmless beyond a reasonable doubt. See 
    18 U.S.C. § 3595
    (c)(2); Jones,
    
    527 U.S. at 402-05
    ; cf. Hitchcock v. Dugger, 
    481 U.S. 393
    , 398-99 (1987); Chapman
    v. California, 
    386 U.S. 18
    , 24 (1967). We are confident that the jury would have
    reached the sentence that it did even if the court had admitted this evidence. See
    Jones, 
    527 U.S. at 402
    ; cf. Sweet v. Delo, 
    125 F.3d 1144
    , 1158-59 (8th Cir. 1997),
    cert. denied, 
    523 U.S. 1010
     (1998). The district court admitted significant expert
    testimony regarding Mr. Purkey's brain abnormalities and their impact on his mental
    and emotional health. The jury was not, therefore, precluded from considering
    Mr. Purkey's mental and emotional impairments as potential mitigating factors; it was
    merely precluded from considering one of several possible explanations as to the
    cause of these alleged impairments. And, although we recognize that a jury may be
    more likely to believe that someone suffers from a problem if its cause is explained,
    we nevertheless harbor no doubt that considering the minimal probative value of the
    evidence and the overwhelming evidence and jury findings of serious aggravating
    factors, its exclusion was harmless. Cf. United States v. Bernard, 
    299 F.3d 467
    , 487
    (5th Cir. 2002), cert. denied, 
    539 U.S. 928
     (2003).
    Mr. Purkey also assigns error in the district court's refusal to allow him to
    impeach Dr. Park Dietz by inquiring into an error that the doctor made when testifying
    in the case of Yates v. State, Nos. 01-02-00462/00463, 
    2005 WL 20416
     (Tex. Ct. App.
    -24-
    Jan. 6, 2005). When serving as an expert witness for the state in the Yates case,
    Dr. Dietz erroneously testified that the facts of an episode of a television show on
    which he consulted, "Law & Order," were very similar to those in Yates. In fact, no
    such episode existed. 
    Id.
     at *3-*4. Dr. Dietz, during a proffer session conducted
    outside of the hearing of the jury in Mr. Purkey's case, freely admitted to the error that
    he had made in the Yates trial. The district court, however, sustained the government's
    objection to testimony about the error because it would "create[] confusion and [was]
    collateral."
    In response to Mr. Purkey's argument, the government asserts that the exclusion
    of this evidence was proper under Federal Rule of Evidence 403. But that is not the
    controlling law here. This is an FDPA case, and its evidentiary standard must govern.
    See Lee, 
    274 F.3d at 494-95
    . Accordingly, we review this issue under the standard of
    § 3593(c), which provides for the exclusion of evidence "if its probative value is
    outweighed by the danger of creating unfair prejudice, confusing the issues, or
    misleading the jury." 
    18 U.S.C. § 3593
    (c); see Lee, 
    274 F.3d at 494
    .
    Although one of the court's reasons, that the testimony would "create[]
    confusion," is arguably consistent with a permissible reason under the FDPA, we
    cannot conclude that the district court acted correctly when it refused to permit any
    inquiry into Dr. Dietz's previous mistake. This testimony would have been relevant
    to demonstrate the doctor's fallibility. Further, we cannot agree with the district court
    that this testimony would have resulted in confusion. Dr. Dietz freely admitted that
    he erred; that was not in dispute. The nature of Dr. Dietz's error, moreover, was not
    unusually complex or confusing. Therefore we can find no reason to conclude that
    the probative value of this testimony was "outweighed by the danger of creating unfair
    prejudice, confusing the issues, or misleading the jury," 
    18 U.S.C. § 3593
    (c).
    -25-
    We nevertheless conclude that the error was harmless. Mr. Purkey's cross-
    examination of Dr. Dietz was otherwise extensive. During that cross-examination,
    Mr. Purkey was able to extract concessions from Dr. Dietz that he had made mistakes
    in two other cases in which he had testified. And, although we do not doubt that the
    excluded information would have provided a morsel of additional probative evidence
    of Dr. Dietz's ability to err, given the otherwise extensive cross-examination that
    allowed the defense to bring out his other errors, and the overwhelming number and
    the nature of the aggravating factors found by the jury, we cannot conclude that the
    absence of this additional information affected Mr. Purkey's substantial rights. See
    
    18 U.S.C. § 3595
    (c)(2); Jones, 
    527 U.S. at 402-05
    ; Hitchcock, 
    481 U.S. at 398-99
    ; cf.
    Bernard, 
    299 F.3d at 487
    ; Sweet, 
    125 F.3d at 1158-59
    .
    Mr. Purkey also maintains that the district court erred by denying his request
    to allow Dr. Peterson to present surrebuttal testimony in response to the testimony of
    Dr. Helen Mayberg. Dr. Mayberg's testimony was presented to rebut the conclusions
    of the defense's experts regarding Mr. Purkey's alleged brain injuries. The defense
    requested that it be allowed to introduce surrebuttal evidence pertaining to two of
    Dr. Mayberg's conclusions: that Mr. Purkey could not have suffered significant brain
    injuries in automobile accidents that occurred in 1968 and 1972, and that Mr. Purkey's
    functioning as a "jailhouse lawyer" was inconsistent with the sort of brain damage
    reported by the defense's medical experts.
    The government argues that the court did not err in excluding this surrebuttal
    testimony because Dr. Mayberg's rebuttal testimony did not raise a new matter. The
    decision of whether to allow a party to present evidence in surrebuttal is generally
    committed to the discretion of the trial court, see United States v. Wilford, 
    710 F.2d 439
    , 452 (8th Cir. 1983), cert. denied, 
    464 U.S. 1039
     (1984), and surrebuttal is
    typically thought appropriate only when new matters are raised in the rebuttal
    -26-
    testimony, see United States v. Barnette, 
    211 F.3d 803
    , 821 (4th Cir. 2000); cf.
    Wilford, 
    710 F.2d at 452
    .
    We do not think that the FDPA alters this standard. Cf. Barnette, 
    211 F.3d at 820-21
    . Although the FDPA dispenses with the rules governing the admission of
    evidence during criminal trials, it is not sensible to read this statutory imperative as
    also divesting the trial judge of his or her traditional authority to control the mode and
    order of the interrogation of witnesses and the presentation of evidence. A contrary
    reading would transform the FDPA sentencing hearing into an evidentiary mélee.
    Even assuming that Dr. Mayberg's testimony that Mr. Purkey's work as a
    "jailhouse lawyer" demonstrated his lack of significant brain damage presented a new
    matter, thereby making surrebuttal appropriate, we cannot conclude that this putative
    error provides an adequate ground for reversal. As mentioned previously, Mr. Purkey
    presented a significant amount of testimony regarding his assertion that he suffered
    from brain damage. This additional testimony would have, at best, offered only
    marginal additional support for this defense. When we consider this fact combined
    with the significant number and serious nature of the aggravating factors advanced by
    the government and found by the jury, we cannot conclude that this error affected
    Mr. Purkey's substantial rights. See 
    18 U.S.C. § 3595
    (c)(2); Jones, 
    527 U.S. at
    402-
    05; Hitchcock, 
    481 U.S. at 398-99
    ; cf. Bernard, 
    299 F.3d at 487
    ; Sweet, 
    125 F.3d at 1158-59
    .
    Finally, Mr. Purkey asserts that the district court erred by overruling his
    objection to questions that the government asked on cross-examination of
    Dr. Peterson, one of Mr. Purkey's expert witnesses. Specifically, Mr. Purkey's counsel
    objected to the government's inquiry into Dr. Peterson's views on the death penalty.
    Even under the traditional rules of evidence, "cross-examination regarding
    potential bias of a witness is proper." United States v. Amerson-Bey, 
    898 F.2d 681
    ,
    -27-
    682 (8th Cir. 1990); see United States v. McCoy, 
    131 F.3d 760
    , 760-61 (8th Cir. 1997)
    (per curiam). If Dr. Peterson strongly disfavored the death penalty, knowledge of that
    would be relevant to the jury's evaluation of his credibility in testifying to factors that
    could mitigate Mr. Purkey's sentence; " 'exposure of a witness' motivation in testifying
    is a proper and important function of ... cross-examination,' " Van Arsdall, 
    475 U.S. at 678-79
     (quoting Davis, 
    415 U.S. at 316-17
    ). To the extent that the FDPA alters this
    rule, it relaxes it, see 
    18 U.S.C. § 3593
    (c); Lee, 
    274 F.3d at 495
    ; a fortiori the district
    court did not err in allowing the government to continue its line of inquiry into
    Dr. Peterson's beliefs about the death penalty.
    In addition to considering whether each of the evidentiary errors that we have
    found is individually sufficient to require reversal, we have also considered, sua
    sponte, what cumulative effect these errors might have had upon Mr. Purkey's
    substantial rights. Cf. United States v. Steffen, 
    641 F.2d 591
    , 597-98 (8th Cir. 1981),
    cert. denied, 
    452 U.S. 943
     (1981). After careful review, we also conclude that the
    errors, even when taken cumulatively, are harmless.
    B.
    Mr. Purkey next maintains that the district court erred by denying his motion
    for allocution during the penalty phase of the trial; Mr. Purkey sought to make a
    statement before the jury without being subject to cross-examination. Although
    Mr. Purkey was permitted to address the district court before it imposed his sentence,
    he argues that the court functionally deprived him of his right to allocution, because
    it lacked any discretion to impose a sentence other than the one that the jury already
    had recommended, see 
    18 U.S.C. § 3594
    . The district court's error, he maintains,
    violated his constitutional rights, Rule 32 of the Federal Rules of Criminal Procedure,
    and the FDPA, see 
    18 U.S.C. §§ 3592
    (a)(8), 3593(c). We disagree.
    First, our circuit previously has recognized that the right to allocution does not
    emanate from the Constitution. See United States v. Patterson, 
    128 F.3d 1259
    , 1260
    -28-
    (8th Cir. 1997) (per curiam); see also Barnette, 
    211 F.3d at 820
    ; Hall, 
    152 F.3d at 396
    .
    Therefore, even if Mr. Purkey were correct that the district court denied him the right
    to allocution, the error would not be a constitutional one.
    Second, Mr. Purkey does not have a statutory right to make statements to a jury
    during the penalty phase of an FDPA trial without being subject to cross-examination.
    Rule 32(i)(4)(A)(ii) requires that "[b]efore imposing sentence," the district court must
    "permit the defendant to speak or present any information to mitigate the sentence."
    The district court satisfied Rule 32 when it allowed Mr. Purkey to speak "before
    imposing sentence." See Hall, 
    152 F.3d at 392
    . Although Mr. Purkey's allocution
    could not have mitigated his sentence because it followed the jury's recommendation
    of the death penalty, see 
    18 U.S.C. § 3594
    , nowhere does Rule 32 grant Mr. Purkey
    a right to allocution before a jury; Rule 32 speaks only of "the court." We agree with
    the Fifth Circuit that Rule 32(i)(4)(A)(ii) should not be interpreted to entitle
    Mr. Purkey to a right of allocution before the jury "when the plain language of the rule
    does not dictate such an interpretation." Hall, 152 F.3d at 393; see also Barnette,
    
    211 F.3d at 820
    . As for the FDPA, nowhere does it mention a right to allocution or
    anything comparable; Mr. Purkey's claimed right on that ground therefore does not
    exist.
    C.
    Mr. Purkey assigns several errors relating to the jury's special findings and
    recommendation of his death sentence. We previously noted that, to recommend a
    death sentence after determining that the defendant is eligible for such a sentence, the
    jury must unanimously find that the statutory and non-statutory aggravating factors
    "sufficiently outweigh" the mitigating factors. See 
    18 U.S.C. § 3593
    (e). For an
    aggravating factor to enter into the jury's calculation, the government must establish
    "the existence of such a factor ... beyond a reasonable doubt." 
    Id.
     at § 3593(c). The
    standard for mitigating factors, however, is less rigorous. The jury may consider any
    mitigating factor that at least one juror found proved "by a preponderance of the
    -29-
    information." Id. at § 3593(c), (d). After the jury has completed its deliberations, it
    must "return special findings identifying any aggravating factor ... found to exist." Id.
    at § 3593(d).
    Mr. Purkey first contends that the district court erroneously permitted the
    prosecution to present the jury with duplicative aggravating factors, thereby skewing
    the jury's balancing of aggravating and mitigating factors in violation of the eighth
    amendment. Because Mr. Purkey challenges the constitutionality of allegedly
    duplicative aggravating factors, we review the district court's decision de novo. Cf.
    Cooks v. Ward, 
    165 F.3d 1283
    , 1289 (10th Cir. 1998).
    Mr. Purkey's best case for duplication is that the nonstatutory aggravator for
    "[s]ubstantial criminal history" mirrors the statutory aggravator for convictions of
    "two or more offenses punishable by a term of imprisonment of more than one year,
    committed on different occasions, involving the infliction and attempted infliction of
    serious bodily injury and death upon another person." The convictions that the
    government offered to support both aggravating factors were identical.
    We think that the Tenth Circuit is correct to conclude that the same facts can
    support different inferences that form different aggravators. See Medlock v. Ward,
    
    200 F.3d 1314
    , 1319 (10th Cir. 2000) (per curiam), cert. denied, 
    531 U.S. 882
     (2000).
    Otherwise the government would either have to choose one out of several possible
    aggravating factors for each instance of a defendant's misconduct or pack into a single
    aggravator multiple negative inferences that could be drawn from the misconduct and
    then risk the jury's rejection of the aggravator due to disagreement over just one of the
    inferences.
    Even under the Tenth Circuit's standard, however, we agree with Mr. Purkey
    that the nonstatutory aggravating factor duplicated the statutory one. The government
    used the same set of convictions each time for the same purpose, namely to show the
    -30-
    defendant's criminal history. The nonstatutory aggravating factor did refer to a fact
    of Mr. Purkey's criminal history that went unmentioned in the statutory aggravating
    factor, namely, that Mr. Purkey "shot Gregg W. Carlberg on or about August 3, 1980."
    Even if this fact were enough to distinguish the two aggravators, though, it overlaps
    with a separate statutory aggravating factor based on Mr. Purkey's conviction of "an
    offense punishable by a term of imprisonment of more than one year, involving the
    use ... of a firearm ... against another person," 
    18 U.S.C. § 3592
    (c)(2) – an aggravator
    that went to the same history of illegal firearm use as did the shooting episode.
    Despite the duplication of aggravators in Mr. Purkey's case, we see no basis for
    the constitutional infirmity of such factors. The Supreme Court has "never before held
    that aggravating factors could be duplicative so as to render them constitutionally
    invalid," Jones, 
    527 U.S. at 398
     (plurality opinion), and we decline to do so when the
    FDPA avoids arbitrary death sentences by requiring juries to weigh aggravating and
    mitigating factors rather than to tally the factors on each side and declare a winner
    based on sheer numbers. See 
    18 U.S.C. § 3593
    (e). But see United States v. Tipton,
    
    90 F.3d 861
    , 899 (4th Cir. 1996), cert. denied, 
    520 U.S. 1253
     (1997); United States
    v. McCullah, 
    76 F.3d 1087
    , 1111-12 (10th Cir. 1996), cert. denied, 
    520 U.S. 1213
    (1997). The district court's jury instructions bolster this view as applied to
    Mr. Purkey's case: The district court ensured that the jury would not employ a tally
    method of evaluating factors when it instructed the jury that "weighing aggravating
    and mitigating factors ... is not a mechanical process. In other words, you should not
    simply count the number of aggravating and mitigating factors. The law contemplates
    that different factors may be given different weights or values by different jurors."
    Of course, had the government introduced an invalid aggravating factor into the
    jury's weighing process, then the government might have violated Mr. Purkey's rights
    under the eighth amendment. See Stringer v. Black, 
    503 U.S. 222
    , 232 (1992). But
    Mr. Purkey asserts no such error here.
    -31-
    Mr. Purkey next requests that our circuit reconsider its precedents that have
    approved jury instructions mandating that a jury recommend a sentence of death
    should it conclude, after balancing aggravating against mitigating factors, that the
    former sufficiently outweigh the latter to justify imposition of a death sentence. He
    recognizes that overruling those precedents would require the action of our en banc
    court and that, as a panel of that court, we are required to give them effect. See United
    States v. Provost, 
    969 F.2d 617
    , 622 (8th Cir. 1992). For our part, we believe that our
    precedents are well-reasoned. See Nelson, 
    347 F.3d at 712
    ; Ortiz, 315 F.3d at 900-01.
    Finally, Mr. Purkey maintains that the FDPA requires juries to identify any
    mitigating factor that at least one juror found to exist and that the district court
    consequently erred by accepting the jury's verdict form. (The verdict form asked the
    jury to record the number of jurors who found each mitigating factor to exist, and the
    jury returned that portion of the form blank.) Because Mr. Purkey presents us with
    a question of law by asking us to interpret the FDPA, we review de novo the district
    court's refusal to order the jury to complete the mitigation portion of the verdict form.
    See United States v. Storer, 
    413 F.3d 918
    , 921 (8th Cir. 2005).
    In a prior case, we hinted that the FDPA does not mandate that jurors identify
    the mitigating factors they find to exist, but we ultimately avoided deciding the
    question. See United States v. Paul, 
    217 F.3d 989
    , 999 n.6 (8th Cir. 2000) (citing
    Hall, 
    152 F.3d at 413
    ). We conclude that in Paul we correctly, albeit tentatively,
    construed the FDPA. Section 3593(d) specifically requires the jury to "return special
    findings identifying any aggravating factor[s] ... found to exist," without any mention
    of identifying such mitigating factors, and so requires no special findings with respect
    to the latter. It is true that the jury's identification of proven mitigating factors
    facilitates appellate review, especially when we have to evaluate the effect of any error
    on the sentence that the jury recommended. Nevertheless, the jury's failure to identify
    proven mitigating factors is entirely proper under the FDPA, and therefore the district
    court did not err by accepting the jury's verdict form.
    -32-
    D.
    In Mr. Purkey's last assignment of error, he argues that the district court erred
    by denying his motion for a mistrial based on alleged prosecutorial misconduct.
    During the penalty phase of the trial, Mr. Purkey interrupted the government's cross-
    examination of a psychiatric expert for the defense, at which point the district court
    excused the jury and Mr. Purkey gave voice to an additional comment that the
    prosecutor interpreted as a threat against him. During the government's subsequent
    cross-examination of a defense expert, who testified to the calming effects of
    medication that Mr. Purkey was taking, the prosecutor asked the expert whether he
    was "aware [that Mr. Purkey] threatened to run my head through yesterday in court,"
    to which Mr. Purkey's counsel immediately objected. The district court sustained the
    objection. Mr. Purkey contends that the prosecutor's question compromised the
    fairness of the penalty proceedings.
    Earlier in our opinion, we rehearsed the legal principles that guide our review
    of alleged prosecutorial misconduct. Cf. Jackson, 41 F.3d at 1233. Even if, as
    Mr. Purkey claims, the prosecutor's question was improper, we conclude that the
    question did not deprive Mr. Purkey of due process: Although the district court failed
    to instruct the jury to disregard the prosecutor's question, it sustained defense counsel's
    objection. Given that defense counsel did not request the court to give the jury a
    cautionary instruction and that the question was brief and isolated, the district court's
    curative action, combined with the overwhelming evidence of aggravating factors,
    ensured that Mr. Purkey was not denied a fair penalty proceeding. See id. This
    remains true even when we take into account any residual effect on the jury from the
    instances of improper prosecutorial conduct that related to Mr. Purkey's tattoos and
    occurred during the guilt phase of Mr. Purkey's trial. We therefore conclude that the
    district court did not err when it denied Mr. Purkey's motion for a mistrial.
    -33-
    V.
    Accordingly, we affirm the judgment of the district court.
