    Appeal from the United States District Court
    for the Southern District of Georgia
    ________________________
    (June 4, 2015)
    Before TJOFLAT, HULL and WILSON, Circuit Judges.
    PER CURIAM:
    Case: 14-11995     Date Filed: 06/04/2015   Page: 2 of 41
    After a jury trial, defendant Andrew Nelson appeals his convictions and
    sentences for armed bank robbery and using, carrying, and brandishing a firearm
    during a crime of violence. Following a careful review of the record and briefs, we
    affirm in part and dismiss the appeal in part.
    I. BACKGROUND
    At trial, Nelson admitted the offense conduct charged but claimed insanity
    based on his bipolar disorder and alleged inability to remember committing the
    robbery. We therefore only briefly discuss the evidence of Nelson’s offenses and
    then more extensively discuss his development and presentation of an insanity
    defense.
    A.    Offense Conduct
    On January 5, 2013, Nelson entered a Wells Fargo bank in Martinez,
    Georgia, carrying a duffel bag and wearing all black, including a hood, a mask,
    gloves, and sunglasses. Nelson brandished a fully loaded 9-millimeter pistol upon
    entering the bank and demanded that the bank tellers load money “with no dye
    packs” into his duffel bag. After the bank tellers placed $2,357 in cash in the bag,
    along with a dye pack, Nelson fled the bank on foot into nearby woods.
    Meanwhile, based on a silent alarm call from the bank, law enforcement
    officers responded to the scene and established a perimeter around the bank.
    Within minutes of the silent alarm call, officers located and detained Nelson near
    2
    Case: 14-11995     Date Filed: 06/04/2015   Page: 3 of 41
    the woods by the bank. Nelson’s 9-millimeter pistol and hands appeared red from
    an apparent explosion of the dye pack.
    From the woods near the bank, officers recovered Nelson’s duffel bag,
    which contained the money from the robbery covered in red dye, a jacket doused in
    Clorox bleach, a fully loaded magazine that fit the 9-millimeter pistol, and a mask.
    Subsequently, law enforcement found Nelson’s Mercury Marquis parked across
    the street from the bank and learned that Nelson purchased both the pistol and the
    mask within two days before the robbery.
    B.    Indictment and Appointment of Counsel
    On February 7, 2013, a grand jury indicted Nelson for one count of armed
    bank robbery, in violation of 18 U.S.C. § 2113(a) and (d), and one count of using,
    carrying, and brandishing a firearm during a crime of violence, in violation of 18
    U.S.C. § 924(c)(1)(A)(ii).
    Nelson submitted an affidavit of indigency, and the district court appointed
    an attorney to represent him pursuant to the Criminal Justice Act (“CJA”).
    C.    Pre-Trial Competency and Sanity Examinations
    After pleading not guilty, Nelson provided notice of his intention to pursue
    an insanity defense and filed an unopposed motion for a psychiatric or
    psychological examination to determine competency and sanity. In support of the
    motion, Nelson alleged that he suffered Post–Traumatic Stress Disorder (“PTSD”)
    3
    Case: 14-11995      Date Filed: 06/04/2015      Page: 4 of 41
    while in the Air Force. A magistrate judge granted Nelson’s motion for a
    psychiatric or psychological evaluation, and Nelson was subsequently evaluated at
    the Metropolitan Correctional Center (“MCC”), a federal prison in New York.
    MCC forensic psychologist Dr. Kari Schlessinger prepared lengthy
    competency and criminal responsibility reports that were submitted to the district
    court on June 10, 2013. The evaluations included information about Nelson’s
    background reported by Nelson himself, including that during his service in the Air
    Force he was sent to learn Arabic and Mandarin at the Defense Language Institute.
    During his service he was incarcerated for six months for a conspiracy to commit
    murder charge unrelated to this case. 1 Nelson claimed that, during this
    incarceration, he suffered physical and sexual abuse that he did not initially report
    to anyone. As a result of the abuse, beginning in 2002, he suffered from PTSD,
    including experiencing nervousness, nightmares, flashbacks, and panic attacks.
    However, Nelson did not seek any treatment for his PTSD symptoms
    because he was concerned about maintaining his military security clearance.
    Instead, according to Nelson, he was formally diagnosed with PTSD in 2010 when
    he underwent a Veterans Affairs (“VA”) disability screening. During that
    1
    The record indicates that Nelson eventually was exonerated of the conspiracy to commit
    murder charge but does not explain whether Nelson was acquitted or the charge was otherwise
    dropped.
    4
    Case: 14-11995     Date Filed: 06/04/2015      Page: 5 of 41
    screening, Nelson told the evaluator about his recurring nightmares and panic
    attacks but not the sexual assault.
    Nelson’s competency and criminal responsibility reports also included a
    section on the findings of Dr. Tin Chin, a contract psychiatrist at MCC, who
    conducted a routine psychiatric evaluation of Nelson. During the evaluation,
    Nelson reported that he was honorably discharged from the Air Force in 2010.
    Nelson identified the bank robbery as the cause of his arrest but stated he could
    only “vaguely recall what occurred or the reasons for his actions.” He also
    reported the 2002 sexual abuse, as well as the flashbacks and insomnia that
    resulted from the abuse. Dr. Chin concluded that Nelson may have suffered an
    episode of impulsive behavior followed by a period of dysphoric mood. Based on
    Nelson’s self-reported symptoms, Dr. Chin diagnosed him with bipolar disorder
    and prescribed risperidone, an antipsychotic medication.
    Dr. Schlessinger’s competency and criminal responsibility reports further
    noted that Nelson’s performance on psychological tests indicated “possible
    exaggeration of symptoms and a cry for help.” Based on the psychological tests,
    the reports indicated Nelson’s intellectual abilities to be above average. In the
    reports, Dr. Schlessinger diagnosed Nelson with PTSD based on his reported
    symptoms from his sexual assault. She also diagnosed him with personality
    disorder and schizoid and narcissistic personality traits.
    5
    Case: 14-11995       Date Filed: 06/04/2015       Page: 6 of 41
    In support of the schizoid and narcissistic personality traits diagnosis, the
    competency and criminal responsibility reports noted Nelson’s preference to spend
    time alone, overestimation of his abilities and inflation of his accomplishments,
    “pervasive pattern of grandiosity,” sense of self importance, and lack of empathy.
    The reports noted that he “embellished his job skills,” and presented himself as
    “haughty” and “all-knowing” during the interviews.
    Ultimately, Dr. Schlessinger concluded that Nelson was both competent to
    stand trial and sane at the time of his offenses. 2 As to competency, Dr.
    Schlessinger noted that, despite Nelson’s PTSD, he possessed an understanding of
    the criminal proceedings, the capacity to assist counsel in his defense, and could
    rationally make decisions regarding legal strategy.
    As to criminal responsibility, Dr. Schlessinger concluded that, at the time of
    the offenses, Nelson’s PTSD did not impair his ability to appreciate the
    wrongfulness of his conduct. The report acknowledged Nelson’s claim that his
    memory of the crime consisted only of “disjointed ‘still frame pictures’ of the
    incident.” Leading up to the robbery offense he recalled feeling depressed,
    missing his children, having a panic attack, and buying a larger gun in case he
    decided to commit suicide. He described the details of his robbery offense as a
    “mystery” and recalled being arrested in the woods and waking up in jail.
    2
    Following Dr. Schlessinger’s reports, the parties stipulated to Nelson’s competency to
    stand trial.
    6
    Case: 14-11995    Date Filed: 06/04/2015    Page: 7 of 41
    Dr. Schlessinger reasoned, however, that the statements and reports of the
    investigating officers regarding the robbery revealed that Nelson’s conduct on the
    day was not “erratic, bizarre, or unusual.” For example, the bleach on Nelson’s
    items that were recovered near the scene of the robbery suggested that he planned
    ahead and anticipated using the bleach to clean items if given a dye pack at the
    bank. His other conduct showed “clear intent, strategic thinking, . . .
    premeditation, . . . [and] prudence and effort in minimizing the risk of detection,”
    including purchasing and loading a gun, disguising his identity, and instructing the
    bank tellers not to insert dye packs. Thus, although Nelson suffered from PTSD,
    he was rational at the time of the robbery offense, understood his conduct, and was
    able to appreciate the wrongfulness of his conduct.
    D.    Pre-Trial § 3006A(e) Motion for Appointment of Mental Health
    Experts, a Private Investigator, and Additional Legal Counsel
    In July 2013, following the submission of Dr. Schlessinger’s reports, Nelson
    moved pursuant to 18 U.S.C. § 3006A(e) for appointment of independent
    psychiatric or psychological experts, as well as a private investigator and
    additional legal counsel, to assist in the development and presentation of an
    insanity defense. In the motion, Nelson’s counsel asserted that based upon the
    totality of the criminal responsibility report, including the PTSD diagnosis by Dr.
    Schlessinger and the bipolar disorder diagnosis by Dr. Chin, Nelson had a basis for
    raising an insanity defense. Nelson’s counsel also opined that Nelson’s behavior
    7
    Case: 14-11995     Date Filed: 06/04/2015    Page: 8 of 41
    on the day of the robbery was “bizarre[] based upon his character and past,” given
    that he had a clean criminal record and was formerly employed as a contractor for
    the National Security Agency (“NSA”), “extremely intelligent,” and fluent in
    Arabic and Mandarin.
    The § 3006A(e) motion was also based, in part, upon claims by some of
    Nelson’s family members that he possibly suffered from multiple personality
    disorder. In support of the request for a private investigator, Nelson’s counsel
    stated that Nelson’s ex-wife potentially had information concerning his mental
    health but was not being cooperative, and thus assistance was needed to obtain
    information from her. The § 3006A(e) motion requested the assistance of
    additional counsel due to the complexity of the insanity defense. Finally, the
    motion also noted that Nelson was receiving VA benefits following the
    determination that he was “50% disabled based upon his mental condition.”
    E.    Pre-Trial § 3006A(e) Hearing
    On July 30, 2013, the district court held a hearing on Nelson’s § 3006A(e)
    motion, at which “the issues of Nelson’s sanity and competency were explored.”
    Responding to questions from both his counsel and the district court, Nelson
    testified that, during his time in the Air Force, he studied languages at the military
    language school in Monterey, California, and served as a cryptologic linguist. He
    studied both Chinese and Arabic and received an associate’s degree in Arabic.
    8
    Case: 14-11995       Date Filed: 06/04/2015       Page: 9 of 41
    Nelson also testified that he was sexually assaulted while in the Air Force but
    never reported the assault for fear of jeopardizing his security clearance. During
    his “out-processing” from the Air Force, he was diagnosed with PTSD after
    suffering depression and thoughts of suicide. As a result, Nelson received $810
    per month in VA disability benefits. Following his discharge from the Air Force,
    he worked as a contractor for the NSA.
    Linda Nelson (“Linda”), Nelson’s mother, testified that she believed her son
    suffered from manic depression. She had seen him experience depression in the
    past, including in middle school when he was almost institutionalized after cutting
    himself. Linda had also heard of Nelson using the identity “Jacob Kane” in public
    and online. Linda claimed that Nelson was highly intelligent and received bad
    grades in school only because he failed to apply himself.
    The district court continued the July 30, 2013 hearing for further inquiry,
    stating that it wished to consider additional information and review Nelson’s Air
    Force and VA records.
    Three weeks later, on August 20, 2013, the district court issued a written
    notice setting the continued hearing for two days later, August 22, 2013.3
    At the August 22, 2013 hearing, the district court indicated that, to rule on
    the necessity of appointing mental health experts, it needed to test Nelson’s alleged
    3
    There is no indication that Nelson or his counsel requested a continuance of the August
    22 hearing.
    9
    Case: 14-11995        Date Filed: 06/04/2015       Page: 10 of 41
    “fluency” in foreign languages. 4 The district court noted that Nelson’s foreign
    language skills were not “determinative of anything,” but indicated that it viewed
    Nelson’s claimed fluency in Arabic and Mandarin as relevant to his credibility in
    alleging mental illness.
    Accordingly, the district court called two foreign language experts, Walter
    Cheng and Christopher Pratt, to test Nelson’s foreign language skills in Mandarin
    and Arabic, respectively. Nelson’s attorney did not object to the appointment or
    calling of these witnesses. Prior to the language examinations, Nelson addressed
    the district court and represented that he could speak Mandarin only
    “conversational[ly]” but claimed that he had far more experience with—and could
    read and write—Arabic. Nelson indicated that he had not used Mandarin since
    2002 but had used Arabic more recently.
    Court-appointed expert Cheng tested Nelson’s verbal and reading abilities in
    Mandarin and found that Nelson spoke “very few” words, could not read basic
    questions, and did not have even a “kindergarten” level of proficiency in the
    language. Nelson’s attorney declined the opportunity to question Cheng about his
    qualifications as a linguist in English and Mandarin. On cross-examination by
    Nelson’s attorney, Cheng conceded that an individual would likely lose their
    4
    On the day of the August 22, 2013 hearing, the district court entered a written order
    specifically ordering that Nelson be tested on his foreign language skills and appointing two
    language experts to that end.
    10
    Case: 14-11995     Date Filed: 06/04/2015   Page: 11 of 41
    ability to speak or understand Mandarin if that individual did not use the language
    for ten years.
    Court-appointed expert Pratt tested Nelson’s verbal and written skills in
    Arabic and found that Nelson scored a 2 out of 10 in verbal proficiency and a 7 out
    of 10 in written proficiency. Nelson’s attorney extensively cross-examined Pratt
    on his method of testing Nelson and whether the dialect of Arabic to which Nelson
    had been exposed would have any effect on his abilities.
    F.    District Court’s Order Denying § 3006A(e) Motion
    Following the hearing, the district court issued a detailed and comprehensive
    34-page order denying Nelson’s § 3006A(e) motion for the appointment of an
    independent mental health expert, investigator, and additional counsel. The district
    court found that Nelson was not entitled to “investigative, expert, or other
    services” under § 3006A(e) because he had not shown that the expert services were
    necessary for adequate representation. Specifically, Nelson had not demonstrated
    that he had a plausible insanity defense.
    In support of its finding that Nelson’s insanity defense was implausible, the
    district court reviewed four categories of evidence presented at, or submitted in
    connection with, the hearing on Nelson’s § 3006A(e) motion. First, the district
    court thoroughly described Dr. Schlessinger’s reports, including her conclusion
    that Nelson was criminally responsible for his crimes. The court found that Dr.
    11
    Case: 14-11995       Date Filed: 06/04/2015       Page: 12 of 41
    Schlessinger’s evaluation of Nelson, including her observation that he had an
    inflated sense of self worth, “hit the nail on the head,” and the court “fully adopted
    and endorsed” her reports.
    Second, the district court extensively examined Nelson’s VA records, which
    included medical records from an Army medical center at Fort Gordon, Georgia,
    where Nelson was seen multiple times during his time in the Air Force.5 The court
    noted that, although the medical records dated back to July 2005, the first mention
    of any mental issue was not until October 2009.
    Specifically, on October 26, 2009, Nelson presented to the medical center’s
    psychology department with complaints of depression, anxiety, and sleep
    disturbances based on problems at work and home, including the pending divorce
    from his wife. Nelson also stated that his depression, anxiety, and nightmares
    resulted from the 2002 incident in which he was falsely accused and imprisoned.
    Nelson reported cynicism of the justice system and distrust of law enforcement
    following the incident, but he denied any sexual contact without his consent.
    Nelson was diagnosed with “Major Depression Single Episode Moderate.”
    On November 18, 2009, Nelson appeared for an appointment with the
    medical center’s psychology department. He was diagnosed with “Adjustment
    5
    The district court noted that Nelson was never deployed to combat during his military
    career.
    12
    Case: 14-11995       Date Filed: 06/04/2015      Page: 13 of 41
    Disorder with Depressed Mood” but was not prescribed any medication. Nelson’s
    medical center records included no further entries from the psychology department.
    Between June and October 2010, Nelson presented repeatedly to the Army
    medical center with back pain and was prescribed pain medications and anti-
    inflammatories. At multiple times during these visits Nelson denied having any
    symptoms of depression or sleep disturbances.
    During this same time period, on August 16, 2010, Nelson appeared at the
    medical center as protocol for his involuntary separation from the Air Force. The
    medical report from that date states that Nelson was not claiming any disability
    benefits.
    On October 27, 2010, Nelson came to the medical center both because of
    claimed back pain and to complete paperwork for his discharge from the Air Force.
    Nelson reported that he was not experiencing any depression and requested a
    waiver of his exit physical exam. A physician signed the necessary paperwork for
    Nelson to receive a waiver of the physical exam.
    On November 8, 2010, however, Nelson filed a VA form claiming
    entitlement to benefits based on the following disabilities: “low back pain with
    radiculopathy,” “adjustment disorder with depressed mood,” “insomnia,” and
    “anhedonia,” all with a listed onset date of October 2010. 6
    6
    Nelson subsequently withdrew his claim for disability based on back problems.
    13
    Case: 14-11995    Date Filed: 06/04/2015    Page: 14 of 41
    Because of the claimed adjustment disorder, the VA sent Nelson to an
    independent contractor, QTC Medical Services. On June 3, 2011, Nelson reported
    to the QTC Medical Services examiner that he was stabbed during his 2002
    incarceration. As a result, he alleged suffering from “panic attacks more than once
    a week, impairment in short and long term memory (e.g. retention of only highly
    learned material, forgetting to complete tasks), . . . disturbances of motivation and
    mood[,] . . . [and] difficulty establishing and maintaining relationships because of
    irritability and anxiety.”
    Based on this single evaluation and “Nelson’s self-reports,” the examiner
    gave Nelson a 50 percent disability rating for “PTSD (claimed as adjustment
    disorder with depressed mood, insomnia and anhedonia).” The examiner also
    noted that Nelson’s reported symptoms during his November 2009 visit to the
    Army medical center, although diagnosed as adjustment disorder, were consistent
    with PTSD. The VA records of Nelson’s disability benefits also “indicate[d] that
    Nelson’s PTSD diagnosis [was] non-sexual in nature.”
    In September 2012, less than six months before the bank robbery, Nelson
    received a lump-sum disability payment of $16,413, retroactive to the November 2,
    2010 onset date of his PTSD. Thereafter he received $810 per month for his
    disability.
    14
    Case: 14-11995   Date Filed: 06/04/2015    Page: 15 of 41
    Third, the district court considered Nelson’s recent financial records. The
    district court noted that, after Nelson’s discharge from the Air Force, he worked as
    an independent contractor at Fort Gordon, reportedly earning $62,500 per year.
    Although Nelson became unemployed in November 2012, his bank account
    records revealed that his usual financial habits—including spending large amounts
    of money on entertainment and clothing—“continued unabated.” For example, in
    the month after he became unemployed, Nelson spent nearly $1,500 on clothing,
    made cash withdrawals totaling $3,000, purchased Cirque de Soleil tickets for
    more than $500, and spent hundreds of dollars on trips.
    Based on Nelson’s bank records, the district court found that in the months
    leading up to the bank robbery, contrary to defense counsel’s claim that Nelson
    was “a depressed man suffering from PTSD,” Nelson was “well-groomed, well
    fed, thoroughly entertained, and well-traveled.” It further appeared that, by the
    time of the bank robbery, Nelson, “having burned through his disability money and
    his salary and relying solely upon the monthly disability check, . . . was at a cross-
    road between have and have not.” The district court found that the expenditures
    were consistent with Dr. Schlessinger’s conclusion that Nelson had a narcissistic
    personality.
    Fourth, the district court reviewed the inconsistencies in Nelson’s testimony
    and his VA records. In particular, the district court focused on the language
    15
    Case: 14-11995       Date Filed: 06/04/2015        Page: 16 of 41
    experts’ assessment of Nelson’s claimed fluency in Arabic and Mandarin, noting
    that Nelson had “failed, miserably,” in communicating with the experts. The
    district court indicated that it had tested Nelson’s purported foreign language
    abilities to gauge his credibility in light of Dr. Schlessinger’s observations that
    “Nelson embellished his job skills and presented himself in a haughty, all-knowing
    way” and demonstrated “narcissistic personality.”
    Given Nelson’s exaggerated claims of fluency in foreign languages, the
    district court concluded a “closer look” at his credibility was “in order,” and it
    recounted several additional inconsistencies bearing on Nelson’s credibility. For
    example, Nelson falsely reported to Dr. Schlessinger that he received outpatient
    treatment for his PTSD and that he had been honorably discharged from the Air
    Force when in fact he had been involuntarily separated following a demotion.
    In light of the above-described evidence, the district court found that
    Nelson’s insanity defense was implausible. 7 The district court recognized that
    Nelson had been diagnosed with PTSD but found that this did “not end the
    inquiry”:
    [A] closer look at the circumstances behind the PTSD disability
    rating, which no doubt played into [Dr. Schlessinger’s] determination,
    leaves a distaste for the process that only serves to lend incredulity to
    the diagnosis. It appears that Nelson’s claim of disability was an
    7
    The district court also found, independent of Nelson’s stipulation to his competency to
    stand trial, that Nelson was competent to stand trial under 18 U.S.C. § 4241 based on Dr.
    Schlessinger’s competency report.
    16
    Case: 14-11995     Date Filed: 06/04/2015   Page: 17 of 41
    afterthought—perhaps suggested by the out-processing clerk who
    filled out the VA [benefits] application for Nelson’s signature.
    The district court noted that Nelson received a 50 percent disability rating based
    upon one episode of depression and self-reports of nightmares and panic attacks.
    In any event, the district court reasoned, “whatever the extent of Nelson’s
    PTSD, it did not interfere with Nelson’s ability to appreciate the wrongfulness of
    his conduct on the day of the robbery.” Based on the criminal responsibility report
    and the district court’s own “examination of the circumstances behind Nelson’s
    PTSD diagnosis and of Nelson himself,” the district court observed:
    Nelson has an inflated sense of self and from what I have observed, he
    is an opportunist and a highly manipulative one. This time, he saw an
    opportunity to exploit his PTSD diagnosis, his alleged loss of
    memory, and his idiosyncrasies to convince his counsel to claim that
    he is not criminally responsible for his actions. The Court, however,
    is not convinced. In short, the defense of mental disease or defect is
    implausible.
    G.    First Jury Trial
    In December 2013, Nelson’s case proceeded to trial. The jury was unable to
    reach a verdict, however, and the district court declared a mistrial. The district
    court reset the trial for February 2014.
    H.    District Court’s § 3006A(f) Order
    Following the district court’s examination of Nelson’s bank account records
    in connection with the § 3006A(e) insanity motion, the court determined that
    Nelson’s earlier affidavit of indigency was “far from complete” and developed
    17
    Case: 14-11995       Date Filed: 06/04/2015       Page: 18 of 41
    “grave concerns about Nelson’s potential for manipulation or abuse of Criminal
    Justice Act funds.” Accordingly, in January 2014, the district court entered an
    order, pursuant to 18 U.S.C. § 3006A(f), directing $8,000 to be paid from Nelson’s
    bank account to the clerk of the court. 8
    The district court noted that Nelson likely had received more than $27,000
    from the VA over the past 18 months and presently had more than $8,000 in his
    bank account. At the time of the order, Nelson’s legal expenses amounted to at
    least $12,227 for legal representation as well as expert witness fees and travel
    costs, and the district court found “no reason in the world why Nelson’s own
    money ought not be tapped and used to pay his witnesses or the lawyer.”
    Nelson moved to reconsider the order, arguing his child support obligations
    should take priority over the CJA payments. The reconsideration motion noted
    that Nelson’s wife testified at his first trial and that “withholding child support
    could create a hostile witness environment.” Attached to the motion were Nelson’s
    divorce decree and child support documentation, showing that he was obligated to
    pay his ex-wife $2,000 per month in child support. The district court denied
    Nelson’s motion for reconsideration.
    8
    Section 3006A(f) provides that if a district court finds funds are available from or on
    behalf of a person furnished CJA representation, it may direct the funds be paid to the appointed
    attorney or to the court to reimburse it for paying the attorney. 18 U.S.C. § 3006A(f).

    I.    Second Jury Trial
    In February 2014, Nelson was retried. At that trial, the government
    introduced evidence of the offense conduct as described above.9
    After the government rested its case, Nelson called four witnesses in support
    of his insanity defense. In relevant part, Nelson’s mother testified that, during
    childhood, Nelson had an attention deficit diagnosis, made few friends, dressed in
    black, and attempted at least once to cut himself at school.
    Nelson’s mother also testified that, since Nelson left the Air Force, he had
    become progressively more depressed, used the name “Jacob Kane” as a false
    identity at times, and sometimes dressed in costume when he left the house.
    Nelson himself took the stand and testified that he sometimes identified
    himself by the pseudonym Jacob Kane or assumed “Jacob Kane” as a persona.
    Nelson also testified concerning the 2002 sexual assault and his diagnosis of PTSD
    upon his discharge from the Air Force.
    As to Nelson’s mental state in the days leading up to the bank robbery,
    Nelson’s mother testified that Nelson was having difficulty sleeping and was not
    himself. Similarly, a former co-worker of Nelson’s at Fort Gordon testified that, in
    the week prior to the bank robbery, Nelson seemed “down and anxious and upset.”
    9
    See 
    discussion supra
    Part I.A.
    19
    Case: 14-11995     Date Filed: 06/04/2015   Page: 20 of 41
    Nelson testified that he did not remember any details of the bank robbery.
    He recalled purchasing a ski mask for jogging outside in the cold and buying the
    gun because he “had been going through a very difficult period” and had
    contemplated suicide. Nelson admitted that in the days preceding the bank robbery
    he spent a lot of money on restaurants, clothing, and entertainment, but described
    this heightened spending and social exposure as an attempt to make himself feel
    better during a time of heavy depression.
    Dr. Chin testified that he diagnosed Nelson with bipolar or manic depressive
    disorder, prescribed Risperdal to treat the bipolar disorder, and determined that
    Nelson had trauma from the 2002 sexual assault. Dr. Chin opined that Nelson
    committed the bank robbery during a manic bipolar episode. Dr. Chin explained
    that bank robberies require high brain activity, a symptom consistent with a manic
    episode, and that manic episodes often involve the formulation of grandiose ideas
    and plans, like planning a bank robbery. Nelson’s behaviors leading up to the
    robbery, including running errands and buying a new gun, were also consistent
    with a manic episode of bipolar disorder. Moreover, denying memory of criminal
    behavior is a common trait among bipolar individuals.
    Upon questioning by the district court, Dr. Chin testified that he assessed
    Nelson at the MCC for only 45 minutes and that, in making his assessment, he
    relied solely upon Nelson’s verbal statements and did not consult medical records.
    20
    Case: 14-11995      Date Filed: 06/04/2015    Page: 21 of 41
    On cross-examination, Dr. Chin conceded that bipolar disorder does not inherently
    mean an individual is unable to understand or appreciate his actions.
    Following the testimony by Dr. Chin, who also testified at Nelson’s first
    trial, the district court dismissed the jury to question Dr. Chin concerning apparent
    improprieties in the voucher he submitted requesting payment for his testimony in
    the first trial. During this questioning, the district court also addressed Dr. Chin
    personally, stating:
    Dr. Chin, . . . I think you’re a very nice, affable person. . . . I will tell
    you, though, very directly and personally that I think you’re a very
    gullible physician to believe some of the stuff this fellow told you,
    and, you know, I believe anybody with a high school education and a
    little look at Wikipedia could talk you out of some pills and I don’t
    think much of what you’ve told us and your unremitting adherence to
    this line of diagnosis in the face of facts to the contrary is bewildering.
    After the defense rested, the government called Dr. Schlessinger as a rebuttal
    witness. Dr. Schlessinger testified that the traits Dr. Chin relied upon in reaching a
    bipolar diagnosis were not consistent solely with bipolar disorder. Nelson’s
    purchase of a gun and mask, his selection of a familiar banking branch, and his
    possession of bleach suggested to Dr. Schlessinger that he planned his offense.
    Such behavior seemed logical, clear, and not consistent with an erratic state. Dr.
    Schlessinger, who conducted a total of nine hours of testing and evaluation,
    believed Nelson was exaggerating his symptoms on the psychological tests.
    The jury found Nelson guilty on both counts of the indictment.
    21
    Case: 14-11995    Date Filed: 06/04/2015    Page: 22 of 41
    J.    Motion for a New Trial
    Nelson moved for a new trial on multiple grounds. First, he argued that the
    district court erroneously denied his § 3006A(e) motion, as the requested expert
    and investigative services were necessary to fully develop his insanity defense.
    Second, the district court improperly conducted a “pop quiz” on his language
    skills, thereby demonstrating bias and prejudice. Third, relatedly, the district
    court’s professed attitude toward Dr. Chin during trial suggested bias and
    prejudice. Finally, the district court erred by seizing funds from his bank account
    to reimburse the court for CJA payments, thus depriving his children of child
    support.
    Following a response by the government, the district court denied the motion
    for a new trial.
    K.    Sentencing
    The presentence investigation report (“PSI”) recommended a base offense
    level of 20 for the armed bank robbery count, pursuant to U.S.S.G. § 2B3.1. The
    PSI added to that base offense level: (1) a two-level increase because the crime
    involved a financial institution, U.S.S.G. § 2B3.1(b)(1); and (2) a two-level
    increase for obstruction of justice, U.S.S.G. § 3C1.1. As to the obstruction-of-
    justice enhancement, the PSI noted that Nelson’s denial of any memory of the
    robbery and claim that he was not in control of his actions during the robbery were
    22
    Case: 14-11995    Date Filed: 06/04/2015    Page: 23 of 41
    against the preponderance of the evidence, and the jury’s guilty verdicts indicated
    they discredited Nelson’s testimony.
    Based on a total offense level of 24 and a criminal history category of I,
    Nelson’s guidelines range for the armed bank robbery count was 51 to 63 months’
    imprisonment. Count Two, the firearm count, carried a mandatory consecutive
    seven-year sentence under 18 U.S.C. § 924(c) and a corresponding seven-year
    guidelines range under U.S.S.G. § 2K2.4(b).
    Prior to sentencing, Nelson objected to the PSI’s failure to apply an
    acceptance-of-responsibility reduction, as well as the assessment of an obstruction-
    of-justice enhancement. Nelson argued that he never denied the operative facts of
    the robbery offense but merely presented evidence in support of his insanity
    defense, a defense founded upon the diagnoses by the Bureau of Prisons’s own
    evaluators. Nelson also requested a downward departure for diminished mental
    capacity, pursuant to U.S.S.G. § 5K2.13, asserting that he committed the offenses
    under the influence of a reduced mental capacity due to his disorders.
    At sentencing, Nelson reiterated his objections, and the district court
    overruled them. As to the obstruction-of-justice and acceptance-of-responsibility
    adjustments, the district court acknowledged that Nelson did not deny the physical
    facts of the robbery offense and that an insanity defense does not automatically
    preclude an acceptance-of-responsibility adjustment. In this case, however, Nelson
    23
    Case: 14-11995     Date Filed: 06/04/2015    Page: 24 of 41
    seemed so incredible that his testimony warranted the obstruction enhancement
    and precluded the acceptance reduction. The district court stated:
    It is my finding by clear and convincing evidence—certainly, more
    than a preponderance—that Mr. Nelson denied any memory of this
    event and that that was, indeed, a lie. It’s not disingenuous. It is
    downright deliberately deceptive and it is the genesis of everything in
    this case that has related to his professed insanity defense. I simply
    don’t believe him. I think the jury didn’t believe him and beyond any
    reasonable doubt didn’t believe him. . . . I will speak for the Court in
    saying that at least by a clear and convincing standard he has falsely
    denied his memory; consequently, his admission of criminal
    responsibility.
    The district court also overruled Nelson’s request for a downward departure based
    on diminished capacity, finding that, if anything, Nelson was very intelligent and
    attempted to fabricate an insanity defense.
    The district court sentenced Nelson to a total sentence of 183 months’
    imprisonment, consisting of a high-end guidelines sentence of 63 months for the
    bank robbery conviction and a consecutive sentence of 120 months for the firearm
    conviction. The sentence on the firearm conviction resulted from an upward
    variance, which the district court imposed in light of the dangerousness of the
    offense and the fear instilled on the individuals in the bank.
    Nelson timely appealed.
    II. APPEAL OF § 3006A(f) ORDER
    On appeal, defendant Nelson raises several issues concerning both his
    convictions and sentences. As an initial matter, before turning to these issues, we
    24
    Case: 14-11995     Date Filed: 06/04/2015    Page: 25 of 41
    dismiss Nelson’s appeal in part to the extent that he appeals the district court’s
    § 3006A(f) order directing CJA reimbursement.
    Nelson argues that the district court erred in seizing his monthly VA benefits
    because the decision: (1) deprived him of favorable testimony by his ex-wife, as
    she was not receiving child support payments; and (2) “usurped certain powers of
    Congress,” as multiple federal statutory schemes, such as the Bankruptcy Code,
    suggest that child support payments should take priority over other types of
    monetary obligations.
    Section 3006A(f) provides that if a district court finds funds are available
    from or on behalf of a person furnished CJA representation, it may direct the funds
    be paid to the appointed attorney or to the court to reimburse it for paying the
    attorney. 18 U.S.C. § 3006A(f).
    In United States v. Griggs, 
    240 F.3d 974
    (11th Cir. 2001), this Court held
    that it lacked jurisdiction to review a district court’s order directing a retained
    attorney to reimburse the CJA fund pursuant to § 3006A(f) for fees she received
    from a client, so that the fund could recover fees and expenses of the client’s
    former court-appointed 
    lawyer. 240 F.3d at 974
    . This Court reasoned that
    “payment orders under § 3006A(f) are not made appealable by the CJA, are left to
    the discretion of the trial judge, are made in an administrative setting, are unrelated
    to the outcome of the case, and can be made without prior adversary hearings.”
    25
    Case: 14-11995     Date Filed: 06/04/2015    Page: 26 of 41
    Id.; see also United States v. Homrighausen, 366 F. App’x 76, 78 n.3 (11th Cir.
    2010) (unpublished) (“Under Griggs, we lack jurisdiction to review the merits of a
    district court’s § 3006A(f) ruling[—]i.e., the finding that funds are available for
    payment and the discretionary decision whether to direct that funds be paid to the
    Treasury as reimbursement for court-appointed counsel[.]”).
    This Court does have jurisdiction, however, to review whether a district
    court “complied with the procedural requirements [of § 3006A] before entering the
    § 3006A(f) ruling.” 
    Id. (citing United
    States v. Bursey, 
    515 F.2d 1228
    , 1236 (5th
    Cir. 1975)). Specifically, the district court is prohibited from summarily
    disbursing funds to the Treasury under § 3006A(f) and instead must first “make an
    ‘appropriate inquiry’ as to the availability of the funds for payment as required
    under subsection (f).” 
    Bursey, 515 F.2d at 1238
    (quoting § 3006A(b)).
    Here, Nelson does not contend that the district court failed to comply with
    the procedures in § 3006A(f) and Bursey before directing payment to the Treasury.
    Instead, Nelson’s argument on appeal goes to the merits of the district court’s
    decision that Nelson’s bank account funds—which he believes should have gone to
    child support payments—were in fact available for payment to the Treasury and
    should be paid to the Treasury as reimbursement for court-appointed counsel.
    26
    Case: 14-11995       Date Filed: 06/04/2015       Page: 27 of 41
    Thus, pursuant to Griggs, we lack jurisdiction to review the district court’s
    § 3006A(f) order and we dismiss Nelson’s appeal in part to the extent that he
    appeals that order.
    We now address Nelson’s convictions claims before turning to his
    sentencing claims.
    III. DENIAL OF § 3006A(e) MOTION
    Defendant Nelson argues that the district court abused its discretion under 18
    U.S.C. § 3006A(e) in denying his motion for the appointment of additional,
    independent mental health experts, a private investigator, and additional legal
    counsel. 10
    Section 3006A(e) provides that a person who is financially unable to obtain
    investigative, expert, or other services necessary for adequate representation may
    request said assistance from the court. 18 U.S.C. § 3006A(e)(1). Upon a finding
    by the court that the services are necessary and the person is financially unable to
    secure them, the court may authorize the services and payment thereof. See 
    id. To demonstrate
    a need for expert services, a defendant must establish that he
    (1) cannot afford the services, and (2) the services are necessary for an adequate
    defense. United States v. Rinchack, 
    820 F.2d 1557
    , 1563 (11th Cir. 1987). In
    10
    We review the district court’s denial of a motion for expert services under 18 U.S.C.
    § 3006A(e) for an abuse of discretion. United States v. Feliciano, 
    761 F.3d 1202
    , 1208 (11th
    Cir. 2014).
    27
    Case: 14-11995       Date Filed: 06/04/2015   Page: 28 of 41
    determining the necessity of requested assistance, a district court may consider
    prior expert assistance, including the results of prior competency determinations,
    or other available evidence. See 
    id. at 1564.
    The court may reject expert
    assistance as not necessary if it concludes that the defendant does not have a
    plausible claim or defense. 
    Id. In Rinchack,
    this Court held that the district court properly denied a request
    for appointment of a psychiatric expert because the defendant failed to show
    necessity. 
    Id. at 1563-65.
    This Court found that nothing in the record suggested
    the expert evaluations already done in the case were flawed. This Court pointed
    out that although there was an expert report favorable to the defendant’s
    incompetency claim, the district court reasonably could have found more
    persuasive a prior report finding the defendant competent. 
    Id. at 1564-65
    (reasoning that the report finding competency was more persuasive because “[n]ot
    only was the report developed over a three month period of time, as compared to
    [the] single office visit [conducted before the report that was more favorable to the
    defendant’s competency claim], . . . it reflected the opinions of several
    psychiatrists and neurologists”). Finally, this Court held that the district court
    could have determined the defendant already had sufficient evidence to present his
    competency claim. 
    Id. at 1565.
    28
    Case: 14-11995     Date Filed: 06/04/2015     Page: 29 of 41
    In addition, we will reverse a district court’s ruling on expert services only if
    the district court’s denial of services caused the defendant prejudice. See United
    States v. Feliciano, 
    761 F.3d 1202
    , 1208-09 (11th Cir. 2014). A defendant cannot
    properly demonstrate prejudice solely on the basis that the denial of expert services
    prevented him from having expert evidence in the form he believed to be most
    persuasive. 
    Id. at 1209.
    In Feliciano, this Court held that where an expert testified
    to the medical condition Feliciano sought extra expert assistance on, the district
    court’s denial of extra assistance to give more in-depth testimony on the medical
    condition did not constitute an abuse of discretion. 
    Id. Based on
    the record before us, we cannot say that the district court abused its
    discretion in denying defendant Nelson’s § 3006A(e) motion for additional,
    independent mental health experts, a private investigator, and additional counsel to
    assist in the development and presentation of his insanity defense. The record
    amply supports the district court’s finding that Nelson did not have a plausible
    insanity defense. See 
    Rinchack, 820 F.2d at 1564
    .
    In examining the plausibility of Nelson’s insanity defense, the district court
    properly considered the prior expert reports already prepared by the MCC’s
    forensic psychologist Dr. Kari Schlessinger and psychiatrist Dr. Tin Chin. See 
    id. The district
    court then reasonably could have found that the conclusions of
    Dr. Schlessinger, who evaluated Nelson through nine hours of interviewing and
    29
    Case: 14-11995     Date Filed: 06/04/2015     Page: 30 of 41
    testing and found that he was sane at the time of his offenses, were more
    persuasive than the bipolar diagnosis and conclusions of Dr. Chin. Dr. Chin tested
    Nelson on only one occasion for 45 minutes and admitted that bipolar disorder did
    not inherently mean a person cannot understand or appreciate his actions. The
    district court also took into account Nelson’s own testimony, finding that he was
    not credible, and extensively reviewed Nelson’s medical and disability records.
    We are unpersuaded by Nelson’s argument on appeal that if the district court
    found that Dr. Chin did not have sufficient time to properly diagnose and treat
    Nelson, this reason “alone would warrant the appointment of another psychiatrist.”
    Regardless of the reliability of Dr. Chin’s report, Dr. Schlessinger’s findings,
    Nelson’s VA records, and Nelson’s own testimony provided an adequate basis for
    the district court’s finding that Nelson did not have a plausible insanity defense.
    In addition, at trial, Dr. Chin testified as to his findings from his psychiatric
    evaluation of Nelson, including the possibility that Nelson suffered from a
    psychiatric episode during the commission of the offense. Although the testimony
    may not have been as comprehensive as Nelson desired, he still benefited from an
    expert’s favorable assistance. For this same reason, Nelson has also failed to show
    prejudice. See 
    Feliciano, 761 F.3d at 1209
    . Given the discretion afforded the fact-
    finder, the district court did not commit reversible error in denying Nelson’s
    § 3006A(e) motion.
    30
    Case: 14-11995      Date Filed: 06/04/2015       Page: 31 of 41
    IV. ALLEGED DUE PROCESS VIOLATIONS
    Defendant Nelson also contends that the district court violated his due
    process rights by (1) denying his § 3006A(e) motion for the appointment of
    additional, independent mental health experts, a private investigator, and additional
    legal counsel, thereby depriving him of a fair trial; and (2) failing to adequately
    notify him of the nature of the continued hearing on the § 3006A(e) motion that
    was ultimately used to quiz him on his language skills. 11
    A.     Denial of § 3006A(e) Motion and Due Process
    Supreme Court precedent establishes that the due process clause of the
    Fourteenth Amendment requires that the government, upon request, provide
    indigent defendants with the “basic tools of an adequate defense . . . when those
    tools are available for a price to other prisoners.” Moore v. Kemp, 
    809 F.2d 702
    ,
    709 (11th Cir. 1987) (en banc) (quotation omitted). However, the government
    “need not provide indigent defendants all the assistance their wealthier
    counterparts might buy; rather, fundamental fairness requires that the [government]
    not deny them an adequate opportunity to present their claims fairly within the
    adversary system.” 
    Id. (quotation omitted).
    A defendant must show a reasonable
    probability that an expert would assist his defense and that the denial thereof would
    11
    We review a constitutional due process claim de novo. See United States v. Hill, 
    643 F.3d 807
    , 874 (11th Cir. 2011). Generally, we review for an abuse of discretion the district
    court’s decisions in conducting pretrial proceedings. See, e.g., United States v. Gamory, 
    635 F.3d 480
    , 490 (11th Cir. 2011).
    31
    Case: 14-11995        Date Filed: 06/04/2015       Page: 32 of 41
    result in a fundamentally unfair trial. 
    Id. at 712.
    In relation to an insanity defense,
    the showing of necessity must demonstrate a substantial basis for the defense. 
    Id. Here, the
    district court’s denial of Nelson’s § 3006A(e) motion did not
    violate his Fourteenth Amendment due process right to a fair trial. For the same
    reasons discussed above that Nelson did not show that he had a plausible insanity
    defense, Nelson failed to demonstrate a reasonable probability that additional
    expert assistance would aid him in an insanity defense or that he had a substantial
    basis for the defense. See 
    id. B. Notice
    of Continued Hearing on § 3006A(e) Motion
    We review a due process claim not properly raised in the district court for
    plain error. 12 United States v. Hayes, 
    40 F.3d 362
    , 364 (11th Cir. 1994). Plain
    error exists when: (1) there was an error, (2) that was plain, (3) that seriously
    affected a defendant’s substantial rights, and (4) that seriously affected the fairness,
    integrity, or public reputation of judicial proceedings. United States v. Acevedo,
    
    285 F.3d 1010
    , 1012 (11th Cir. 2002).
    Generally, a district court’s decision to hold a hearing on pretrial matters lies
    within the court’s sound discretion. See United States v. Gamory, 
    635 F.3d 480
    ,
    12
    Although Nelson argued in his motion for new trial that the district court erred in
    conducting a “pop quiz” on his language skills, there is no indication in the record that Nelson’s
    attorney requested a continuance of the August 22 hearing or contemporaneously objected to the
    district court’s appointment of the language experts.
    32
    Case: 14-11995      Date Filed: 06/04/2015       Page: 33 of 41
    490 (11th Cir. 2011); Cheely v. United States, 
    367 F.2d 547
    , 548-49 (5th Cir.
    1966). As our predecessor Court explained,
    [w]hile a trial judge . . . has a duty to conduct the trial carefully,
    patiently, and impartially, the judge has wide discretion in managing
    the proceedings . . . . He may comment on the evidence, may
    question witnesses and elicit facts not yet adduced or clarify those
    previously presented, and may maintain the pace of the trial by
    interrupting or cutting off counsel as a matter of discretion.
    United States v. Hawkins, 
    661 F.2d 436
    , 450 (5th Cir. Unit B Nov. 1981)
    (quotation omitted).13 A defendant is denied a constitutionally fair trial by the
    district court’s management of the proceedings “[o]nly when the judge’s conduct
    strays from neutrality.” 
    Id. (quotation omitted).
    We conclude that the district court neither abused its discretion nor
    committed plain error (1) by giving only two days’ notice that the hearing on
    Nelson’s § 3006A(e) motion would be continued from July 30, 2013, to August 22,
    2013, and (2) by not giving specific notice that the court was going to have
    language experts at the August 22 hearing. Nelson does not point to a specific rule
    requiring the district court to provide notice of the hearing or information about the
    nature of the hearing. Nor has Nelson identified any precedent showing that the
    district court “stray[ed] from neutrality,” or otherwise violated due process, in
    giving abbreviated notice. See 
    id. 13 All
    Fifth Circuit Unit B decisions rendered after October 1, 1981, operate as binding
    precedent in the Eleventh Circuit. United States v. Maxwell, 
    579 F.3d 1282
    , 1305 n.6 (11th Cir.
    2009).

    Case: 14-11995     Date Filed: 06/04/2015   Page: 34 of 41
    As to Nelson’s testimony, Nelson and his mother already had testified at the
    July 30 hearing. Thus, Nelson’s ability to present his own testimony and that of
    his mother in support of his § 3006A(e) insanity motion was not affected by the
    district court’s abbreviated notice of the subsequent August 22 hearing.
    As to the language experts, the district court reasonably exercised its broad
    discretion over pre-trial proceedings to provide short notice of the August 22
    § 3006A(e) hearing, and to withhold the particular details of the hearing—that
    there would be a language quiz—until the day of the hearing. See 
    id. As the
    district court indicated, it used the language experts as a way to assess Nelson’s
    credibility as to his claimed language skills in light of Dr. Schlessinger’s report
    that Nelson “embellished” details and exhibited a narcissistic personality.
    Advance detailed notice of the hearing could have defeated the purpose of the
    hearing—to spontaneously assess Nelson’s language skills—by giving Nelson
    some opportunity to prepare his language skills or an explanation for his lack of
    skills.
    Nelson also has not shown how earlier or more detailed notice would have
    changed the outcome of the hearing. Nelson contends that the abbreviated notice
    prevented him from challenging the training or expertise of the language experts
    selected by the district court. However, Nelson was given the opportunity to cross-
    examine the language experts and specifically to question them concerning their
    34
    Case: 14-11995     Date Filed: 06/04/2015    Page: 35 of 41
    credentials. And even today Nelson has not proffered anything to call into doubt
    the experts’ assessments of his foreign language abilities. In any event, the
    language assessments formed just one of several grounds on which the district
    court based its finding that Nelson’s insanity defense was implausible. Thus,
    Nelson has not demonstrated that he suffered harm.
    V. NELSON’S REMAINING CONVICTIONS CLAIMS
    On appeal, defendant Nelson raises additional arguments in support of his
    overall claim that he received an unfair trial, which we dispose of summarily.
    Nelson first asserts that the district court’s comment about Dr. Chin’s
    “gullib[ility]” and suggestion that he was improperly awarded VA disability
    benefits demonstrated the court’s bias and failure to give him a fair trial.
    We are unconvinced. The allegedly biased comments by the district court to
    Dr. Chin and regarding the propriety of Nelson’s disability benefits were made
    outside the jury’s presence. We will not reverse a conviction “based upon
    comments of the trial judge unless the comments are so prejudicial as to amount to
    denial of a fair trial,” United States v. Ramos, 
    933 F.2d 968
    , 973 (11th Cir. 1991),
    and the defendant shows that the comments had “a clear effect on the jury,” United
    States v. Morales, 
    868 F.2d 1562
    , 1576 (11th Cir. 1989) (quotation omitted and
    alteration adopted). Nelson has not identified any way that these comments
    reached the jury or influenced the jury’s decision-making process.
    35
    Case: 14-11995     Date Filed: 06/04/2015    Page: 36 of 41
    Nor do we find persuasive Nelson’s argument that the district court’s
    isolated comments show that it generally failed to provide him a fair trial.
    Relatedly, Nelson argues that the district court abused its discretion in
    denying his motion for a new trial because of various instances of unfairness at
    trial, including the denial of expert assistance, the language quiz, and the district
    court’s comments about Dr. Chin and his VA benefits.
    We conclude that Nelson has not demonstrated that these alleged instances,
    taken as a whole, amounted to proceedings so fundamentally unfair as to warrant a
    new trial. See United States v. Sweat, 
    555 F.3d 1364
    , 1367 (11th Cir. 2009);
    United States v. Ramirez, 
    426 F.3d 1344
    , 1353 (11th Cir. 2005). Accordingly, the
    district court did not abuse its discretion in denying Nelson’s motion for a new
    trial.
    VI. SENTENCING ISSUES
    On appeal, defendant Nelson raises three related issues concerning his
    sentence for armed bank robbery. First, he argues that the district court erred in
    enhancing his sentence based on obstruction of justice because he never contested
    the underlying facts of the robbery offense and had a reasonable basis for raising
    an insanity defense. Second, for these same reasons, the district court erred in not
    granting him an offense-level reduction for acceptance of responsibility. Finally,
    the district court erred by denying him a downward departure for diminished
    36
    Case: 14-11995        Date Filed: 06/04/2015       Page: 37 of 41
    capacity pursuant to U.S.S.G. § 5K2.13 because, according to both Dr.
    Schlessinger’s and Dr. Chin’s reports, he suffered from mental illness.14
    Section 3C1.1 of the Sentencing Guidelines provides for a two-level increase
    to the offense level when the defendant “willfully obstructed or impeded, or
    attempted to obstruct or impede, the administration of justice with respect to the
    investigation, prosecution, or sentencing of the instant offense of conviction.”
    U.S.S.G. § 3C1.1. The Application Notes to § 3C1.1 list examples of conduct
    warranting the enhancement, including “committing, suborning, or attempting to
    suborn perjury.” 
    Id. § 3C1.1,
    comment. (n.4(B)).
    When the district court assesses the obstruction-of-justice enhancement
    based on the defendant’s perjury, it “should make specific findings as to each
    alleged instance of obstruction by identifying the materially false statements
    individually.” United States v. Singh, 
    291 F.3d 756
    , 763 (11th Cir. 2002)
    (quotation omitted and alteration adopted). The testimony must have been:
    (1) under oath; (2) false; (3) material; and (4) “given with the willful intent to
    provide false testimony.” 
    Id. at 763
    n.4. For purposes of § 3C1.1, “material . . .
    means evidence, fact, statement, or information that, if believed, would tend to
    influence or affect the issue under determination.” U.S.S.G. § 3C1.1, comment.
    14
    We review findings of fact related to sentence calculation for clear error and review the
    application of the Sentencing Guidelines to the facts de novo. United States v. Williams, 
    527 F.3d 1235
    , 1247-48 (11th Cir. 2008). We also review for clear error the district court’s
    determination regarding a reduction for acceptance of responsibility. United States v. Moriarty,
    
    429 F.3d 1012
    , 1022-23 (11th Cir. 2005).
    37
    Case: 14-11995      Date Filed: 06/04/2015    Page: 38 of 41
    (n.6). We may also affirm an obstruction-of-justice enhancement if the record
    clearly reflects the basis for the enhancement. See United States v. Uscinski, 
    369 F.3d 1243
    , 1246 (11th Cir. 2004).
    Pursuant to U.S.S.G § 3E1.1(a), a defendant is entitled to a two-level
    reduction in his offense level if he clearly demonstrates acceptance of
    responsibility. The commentary to § 3E1.1 states that:
    In determining whether a defendant qualifies under subsection (a),
    appropriate considerations include, but are not limited to, the
    following:
    (A) truthfully admitting the conduct comprising the offense(s) of
    conviction, and truthfully admitting or not falsely denying any
    additional relevant conduct for which the defendant is
    accountable under § 1B1.3 (Relevant Conduct) . . . . However, a
    defendant who falsely denies, or frivolously contests, relevant
    conduct that the court determines to be true has acted in a manner
    inconsistent with acceptance of responsibility[.]
    U.S.S.G. § 3E1.1, comment. (n.1(A)). The reduction for acceptance of
    responsibility “is not intended to apply to a defendant who puts the government to
    its burden of proof at trial by denying the essential factual elements of guilt, is
    convicted, and only then admits guilt and expresses remorse.” 
    Id., comment. (n.2).
    However, a defendant who is convicted at trial is not automatically
    precluded from a reduction. 
    Id. “In rare
    situations a defendant may clearly
    demonstrate an acceptance of responsibility for his criminal conduct even though
    he exercises his constitutional right to a trial.” 
    Id. This may
    occur when a
    38
    Case: 14-11995     Date Filed: 06/04/2015    Page: 39 of 41
    defendant goes to trial “to make a constitutional challenge to a statute or a
    challenge to the applicability of a statute to his conduct.” 
    Id. Finally, this
    Court
    has held that an acceptance-of-responsibility enhancement is not warranted when a
    defendant receives an enhancement for an obstruction of justice. See United States
    v. Arguedas, 
    86 F.3d 1054
    , 1059-60 (11th Cir. 1996).
    Section 5K2.13 of the Guidelines provides for a downward departure if “(1)
    the defendant committed the offense while suffering from a significantly reduced
    mental capacity; and (2) the significantly reduced mental capacity contributed
    substantially to the commission of the offense.” However, the district court may
    not depart downward if “the facts and circumstances of the defendant’s offense
    indicate a need to protect the public because the offense involved actual violence
    or a serious threat of violence.” U.S.S.G. § 5K2.13. This Court has held that if a
    defendant committed a violent crime, the defendant is not eligible for a § 5K2.13
    diminished-capacity departure. See United States v. Salemi, 
    26 F.3d 1084
    , 1087
    (11th Cir. 1994).
    All of Nelson’s sentencing arguments are without merit. First, the district
    court did not clearly err by applying an obstruction-of-justice enhancement.
    Although Nelson did not contest the elements of the underlying bank robbery, the
    record shows that the district court’s finding that Nelson deliberately lied in his
    testimony was not clearly erroneous. In particular, the district court found that
    39
    Case: 14-11995     Date Filed: 06/04/2015    Page: 40 of 41
    Nelson’s claimed lack of memory of the offenses to be “downright deliberately
    deceptive” and a “lie.” We defer to the district court’s credibility finding, see
    
    Singh, 291 F.3d at 763-64
    , and this finding was supported by the record, in
    particular the evidence that Nelson deliberately planned the crime and was
    malingering during his mental health evaluations.
    Second, the district court did not clearly err by declining the reduction for
    acceptance of responsibility. Although a defendant does not automatically forgo
    the acceptance reduction by going to trial, here Nelson did forgo the reduction by
    actively, and falsely, denying memory of the offense conduct. See U.S.S.G.
    § 3E1.1, comment. (n.2). Moreover, given that Nelson’s conduct properly resulted
    in an obstruction-of-justice enhancement, as discussed above, a reduction for
    acceptance of responsibility was not warranted. See 
    Arguedas, 86 F.3d at 1059-60
    .
    Finally, the district court properly declined Nelson’s request for a downward
    departure under § 5K2.13. The language of § 5K2.13 and our precedent clearly
    indicate that a diminished-capacity departure is not available if a defendant
    commits a violent crime or poses a serious risk of violence. See U.S.S.G.
    § 5K2.13; 
    Salemi, 26 F.3d at 1087
    . Nelson committed a violent crime when he
    robbed a bank at gunpoint.

    VII. CONCLUSION
    For the foregoing reasons, we affirm defendant Nelson’s convictions and
    total sentence of 183 months’ imprisonment, and we dismiss Nelson’s appeal in
    part to the extent that he appeals the district court’s § 3006A(f) order.
    AFFIRMED IN PART AND DISMISSED IN PART.
