    PER CURIAM:
    In 2008, a jury in the Eastern District of North Carolina
    convicted appellant Somsak Saeku of two wire fraud offenses, in
    violation      of     
    18 U.S.C. § 1343
    ,          plus    a        single   offense    of
    interstate transportation of stolen property, in contravention
    of 
    18 U.S.C. § 2314
    .                After being sentenced to 108 months in
    prison    by    the    district       court,       Saeku       has       appealed,    pursuing
    multiple challenges to his convictions and sentence.                                 Among his
    contentions, Saeku maintains that the court erred in refusing to
    dismiss the indictment for lack of a speedy trial, and that he
    was denied a fair trial because of references to his race and
    immigration status in the prosecutor’s closing argument.                                     As
    explained below, we affirm.
    I.
    A.
    We begin by describing the circumstances underlying Saeku’s
    fraud    and    interstate         theft    convictions,            as    adduced    from   the
    evidence presented            at   trial.         The    factual         recitation    is   set
    forth    in    the    light    most    favorable         to    the       prosecution.       See
    United States v. Brooks, 
    524 F.3d 549
    , 563 (4th Cir. 2009).
    Under the evidence, Saeku engaged a brazen theft and wire fraud
    scheme    in    eastern       North    Carolina         and    elsewhere,         spanning   a
    period of about five years, during which he shoplifted items in
    2
    bulk       from    retail    stores      and     sold    them    on    the       Internet,     and
    thereafter made false stolen property claims to his homeowner’s
    insurance carrier.
    1.
    In February 2002, an employee at a Barnes & Noble bookstore
    in   Raleigh        observed      Saeku    shove       multiple       CDs    into      his    pants
    before       leaving       the    store.         Several     mall       security         officers
    apprehended Saeku after he reached his vehicle, and the officers
    found the stolen CDs hidden behind a bush near where Saeku had
    been walking.             A subsequent search of Saeku’s vehicle revealed
    CDs,   DVDs,        and    clothing,      which       were   seized     by       the   officers.
    After being given Miranda warnings, Saeku admitted that he had
    stolen the goods seized from his car.
    Three        years    later,       in     February       2005,       at    a    Christian
    bookstore          in     Raleigh,       Saeku       concealed    merchandise            in    his
    clothing, took it to his car, and returned to steal more.                                      The
    manager       confronted         Saeku    and     looked     into      the       trunk    of   his
    vehicle, where “at least” ten to fifteen CDs and DVDs bearing
    the store’s stickers were found.                        J.A. 192. 1         The police were
    summoned          and,    upon   an   officer’s         instruction,         Saeku       produced
    additional stolen merchandise from beneath his clothing.                                        On
    1
    Citations herein to “J.A. __” refer to the contents of the
    Joint Appendix filed by the parties in this appeal.
    3
    August 20, 2005, Saeku stole approximately six DVDs from the
    Family Christian Bookstore in Raleigh, and then stole ten more
    on July 4, 2006.         In December 2005, an employee in the Borders
    Bookstore café in Raleigh saw Saeku pick up approximately eight
    audio books, pull the security stickers from them, and put the
    audios    in   his    pockets.        On    May    24,    2006,    a     barista      at   a
    Starbucks      in    Raleigh    saw     Saeku      conceal       several       CDs   in    a
    newspaper and then leave the store.
    On December 16, 2006, a loss prevention agent at a Best Buy
    store    in     Raleigh,       suspecting         the     theft    of      merchandise,
    confronted     Saeku    and    led    him   to    the    store’s    loss       prevention
    room.       There,     Saeku    pulled      eighteen       CDs    from     beneath        his
    clothing.       The    agent    summoned        police    officers,      who     arrested
    Saeku and searched his vehicle — where they found CDs and DVDs
    “piled high.”          J.A. 223.        As Saeku was being transported to
    jail, he spontaneously confessed to stealing some of the items.
    On December 21, 2006, a floor manager at a Circuit City store in
    Raleigh responded to a customer who had shouted that Saeku was
    stealing.      An employee stopped Saeku briefly, but allowed him to
    leave.      The manager of the store later viewed security tapes
    that    revealed      Saeku    taking    several        stolen    DVDs    to    a    vacant
    register, where he deactivated the security stickers.
    On January 18, 2007, an employee at an Office Depot in
    Raleigh saw Saeku with a computer.                      On confirming that no one
    4
    had paid for the computer, the employee saw Saeku driving away
    with it.    The employee wrote down the license plate information
    and contacted the authorities, and police officers then went to
    Saeku’s house and spoke with him regarding the computer theft.
    Saeku acknowledged that he had recently returned from Office
    Depot and invited the officers into his kitchen.                    The officers
    obtained consent to search Saeku’s house, where they found two
    identical computers, one of which the Office Depot employee had
    reported stolen.       In Saeku’s residence, the officers also found
    large quantities of unopened software, diapers, lawnmowers and
    other lawn equipment, plus extensive mailing supplies.
    2.
    In January 2007, Detective Holly Rinaldo of the Raleigh
    Police    Department,     upon   receiving    information        that    Saeku   was
    selling stolen goods over the Internet, secured and reviewed
    several police reports involving Saeku.               She identified twenty-
    two reports involving theft-related arrests or criminal charges
    against    Saeku     in    the    Raleigh     area.        As     part     of    her
    investigation, Rinaldo placed a tracking device on Saeku’s car
    (with    judicial    authorization),       after   which   she    witnessed      him
    steal merchandise from at least two stores.
    Between July 2006 and May 2007, police officers executed
    four     search     warrants     at   Saeku’s      four-bedroom          residence.
    Detective Rinaldo participated in the last of those searches,
    5
    where she noticed shelving made from PVC tubes in almost every
    room of the residence.                 The shelving was stocked with well-
    organized    inventories          of   unopened     CDs,       DVDs,    textbooks,    and
    audio    books.       Larger       items,       including      power     washers,    lawn
    equipment,    and     fans,    were      stored    underneath       the    house.      The
    other   three     searches     also      revealed       PVC    shelving     and   similar
    inventories.         The    PVC    shelving       was    seized    during     the    first
    search, after which Saeku obtained more shelving and restocked
    his inventories.
    Saeku carried out his theft and stolen property scheme by
    selling stolen goods on the Internet.                    The second search of his
    residence    revealed        extensive      records,          including    post     office
    receipts and records of items shipped, names and addresses of
    recipients,       shipment        dates,    and     prices.            Saeku’s    records
    identified the shipment of 7353 items in 2005, 7469 items in
    2006, and 656 items from January through April 2007.                              Most of
    these    shipments     were       made     to    out-of-state      addresses.         For
    example,    during     a     two-week      period       in    January     2006,   Saeku’s
    records showed 602 sales, more than 96 percent of which involved
    shipments       to    addresses          outside        North      Carolina.           The
    investigators        also    analyzed       bank    deposits       made     to    Saeku’s
    accounts and concluded that the deposits exceeded $331,000, and
    had     resulted      from     sales        of     stolen       merchandise.           The
    6
    investigators calculated the retail value of the items seized
    from Saeku’s residence at more than $552,000.
    On July 22, 2005, Saeku contacted Nationwide Insurance, his
    homeowner’s insurer, and filed a claim seeking indemnity for
    property that had been stolen from his home.                     In October 2005,
    Saeku emailed to a Nationwide claims agent an inventory of items
    that had purportedly been stolen, and also submitted a sworn
    statement to Nationwide in support of his loss claim.                     Among the
    items for which indemnification was sought were computer and
    electronic equipment, furniture, CDs, DVDs, silverware, jewelry,
    several suits of men’s clothing, and books.                      Saeku valued the
    goods     allegedly      stolen    from    his    residence      at    $157,162.30,
    including      $18,821    worth    of     newly    released      DVDs.        Despite
    requests    from   Nationwide,       Saeku      never   provided      proof   of    his
    purchase of any of those items.
    B.
    The grand jury in the Eastern District of North Carolina
    indicted Saeku on October 10, 2007, charging him with two counts
    of wire fraud and a single charge of interstate transportation
    of stolen property.         Saeku first appeared and pleaded not guilty
    in the district court on December 10, 2007.                      On December 17,
    2007,    the   court     entered    a     scheduling     order     requiring       that
    pretrial motions be filed by January 10, 2008, and scheduling
    Saeku’s trial      for    February      2008.     By    subsequent     orders,      the
    7
    court granted Saeku’s two requests for extensions of time to
    file       pretrial    motions.       The       second    of   those    orders      also
    continued      Saeku’s      trial   until   the    court’s     “May    2008   term    of
    court.”       Dist Ct. ECF No. 20. 2             Both of the extension orders
    specified — pursuant to the so-called ends-of-justice exclusion
    of the Speedy Trial Act — that the ends of justice justified the
    periods of delay involved, and thus excluded those periods from
    the seventy-day period within which the Act normally requires a
    defendant to be brought to trial. 3
    On March 13, 2008, Saeku filed several pretrial motions and
    the court conducted a hearing on May 13, 2008.                   By order of June
    16,    2008,    the     court     ruled   on     the     outstanding    motions      and
    rescheduled the trial for June 30, 2008.                    On June 24, 2008, the
    government moved for a trial continuance on the ground that two
    of its “key” witnesses — an expert who would “substantially
    shorten” the trial by “summariz[ing] a large volume of financial
    information,”         and   the   local   law     enforcement    officer      who    had
    coordinated the investigation of Saeku — were “scheduled to be

    out of the area” until July 7, 2008.            Dist. Ct. ECF No. 49, at
    1.    Before filing its continuance motion, the prosecutors had
    contacted Saeku’s lawyer, “who stated that [Saeku] neither joins
    nor concurs in [the] motion, but does not intend to file a
    motion in opposition.”          
    Id. at 2
    .     By order of June 25, 2008
    (the “Continuance Order”), the court granted the government’s
    continuance motion, rescheduling the trial for the “September
    term” of court.     J.A. 97.      The Continuance Order specified that
    it was granted “for good cause shown” and included a handwritten
    notation that the delay was to be excluded from any Speedy Trial
    Act computations.       
    Id.
        It did not, however, reference the ends-
    of-justice exclusion or make any findings relating thereto.              The
    Continuance Order also did not specifically reference any of the
    Act’s other exclusions from the seventy-day period.
    On September 10, 2008, as the prospective jurors entered
    the   courtroom   for   jury    selection,   Saeku,   proceeding   pro   se,
    sought to address the trial court. 4         The court noted the presence
    of the prospective jurors and asked Saeku, “[w]hat do you want
    4
    On September 4, 2008, Saeku sought court approval to
    proceed pro se and represent himself at trial with the
    assistance of standby counsel.      On September 9, 2008, the
    district court conducted a hearing on Saeku’s request for self-
    representation and, by its oral ruling of the same day, granted
    the motion. Saeku then indicated that he was “ready to proceed”
    to trial the next day.        J.A. 112.   On appeal, Saeku is
    represented by appointed counsel. In addition, we granted Saeku
    leave to file a pro se brief.
    9
    to say, quickly?”        J.A. 124.        Saeku stated, without elaborating,
    that he moved to “dismiss this indictment based on the violation
    of    speedy   trial.”       
    Id.
             The     court     took      the    matter       under
    advisement      and   jury     selection         was      conducted.             The    trial
    thereafter     proceeded     to    its    completion,          and    the    court      never
    expressly      addressed     or    disposed         of    Saeku’s     oral       motion      to
    dismiss. 5
    C.
    During the trial, both parties made mention of Saeku’s race
    and    immigration     status.        First,        in     conducting       his        pro   se
    examinations     of   witnesses       and      in   addressing        the    jury,       Saeku
    referenced his race, language skills, and immigration status.
    See, e.g., J.A. 140 (stating his national origin is Thailand);
    J.A. 172 (“Although I speak a few languages, English is not my
    native tongue.”); J.A. 277 (referring to his “green card” and
    Thailand-issued       passport).         Second,         the   prosecutor        began       his
    closing argument by responding to Saeku’s references to race and
    immigration     status,      urging      the     jury     to   “find       the    defendant
    5
    The wire fraud offenses were tried on the theory that
    Saeku had engaged in a scheme to defraud Nationwide Insurance by
    way of two separate communications, the July 22, 2005 phone call
    and the October 2005 email, in both of which he represented that
    he was the rightful owner of the property purportedly stolen.
    The interstate transportation of stolen property offense was
    tried on the theory that Saeku’s interstate shipments of stolen
    goods from Internet sales exceeded the $5000 jurisdictional
    amount required under 
    18 U.S.C. § 2314
    .
    10
    guilty, whether [he is] a citizen or whether [he is] a visitor.”
    J.A. 414.     The prosecutor then reviewed and argued the evidence
    introduced     against   Saeku.    The   prosecutor     concluded   by
    admonishing the jury not to consider the personal attributes
    that Saeku had previously mentioned:
    I urge you to consider the evidence and the law
    only, not whether Mr. Saeku looks a little different
    than some other folks.    He looks a lot like other
    folks. . . . Don’t consider that he is a visitor. He
    has the same constitutional protections as we all do
    as citizens.
    Don’t consider the way he speaks . . . .
    [A]lthough he may speak with an accent and may not be
    a lawyer, he understands and can process thoughts in
    the English language, when he chooses to.
    . . . .
    Disregard the way he looks. Focus on the law and
    the evidence, please.    It’s a part of your duty as
    jurors. It’s a part of the instructions. It’s a part
    of why we have a Constitution that is revered by
    nations of the world.
    J.A. 419.
    On September 11, 2008, the jury returned its verdict of
    guilty against Saeku on all three offenses.           On November 12,
    2008, the district court sentenced Saeku to a prison term of 108
    months, plus three years of supervised release, restitution, and
    forfeiture.     Saeku has filed a timely appeal, and we possess
    jurisdiction pursuant to 
    28 U.S.C. § 1291
    .

    II.
    We review de novo a district court’s interpretation of “the
    Speedy Trial Act, and review any of the court’s related factual
    findings for clear error.”                   United States v. Rodriguez-Amaya,

    ,   440     (4th     Cir.    2008)   (internal      quotation    marks
    omitted).       On the other hand, we review for plain error an
    appellate     contention       that    was     not    preserved     in   the   district
    court.       See Fed. R. Crim. Pro. 52(b); United States v. Olano,
    
    507 U.S. 725
    , 731-32 (1993).
    III.
    As mentioned earlier, Saeku has raised multiple issues on
    appeal, only two of which warrant a sustained discussion.                             More
    specifically, Saeku contends that the grand jury was tainted by
    references to his race and immigration status; that the trial
    court erred in authorizing him to represent himself pro se; that
    the court failed to conduct voir dire and improperly limited his
    peremptory challenges; that the court erred in not dismissing
    the indictment for violations of his speedy trial rights; that
    the court erred by excluding him from bench conferences and in
    not permitting him to deliver exhibits to witnesses; that the
    court erred in denying his motion to suppress evidence seized
    during a      search    of     his    residence;      that    the   court   intervened
    excessively     to     limit    his    examination       of   witnesses;       that    the
    12
    court erred in admitting opinion testimony; that the court erred
    in failing to exclude evidence obtained by the prosecutors in
    violation of his Miranda rights; that the charges against him
    violated the Double Jeopardy Clause of the Fifth Amendment; that
    the   evidence     was     insufficient         to   support       any    of     his    three
    convictions; that the court erred in conducting hearings outside
    his presence; that the court erred in its instructions to the
    jury;    that      the     two      wire    fraud           charges       were      fatally
    multiplicious; that the prosecutor’s closing argument improperly
    referenced       Saeku’s     race    and    immigration            status;       that    the
    sentence imposed by the court was unreasonable; that the court
    erred    in     ordering     forfeiture;         and    that       cumulative          errors
    deprived him of his Fifth Amendment right to due process.
    Put     succinctly,    only    the       speedy       trial       issue    and     the
    assertions regarding the propriety of the prosecutor’s closing
    argument       warrant     further    discussion.                 We     have     carefully
    considered each of Saeku’s other contentions of error and are
    satisfied to reject all of them for lack of merit.                              That said,
    we turn to the speedy trial and closing argument contentions.
    A.
    Under the Speedy Trial Act, the district court was obliged
    to “commence” Saeku’s trial “within seventy days . . . from the
    date [he] has appeared before a judicial officer of the court.”
    
    18 U.S.C. § 3161
    (c)(1).         Pursuant         to    
    18 U.S.C. § 3161
    (h),
    13
    certain    periods         of   delay    are    excluded      from    the   seventy-day
    period    —    that    is,      they    do   not    count    against    the    statutory
    “speedy-trial clock.”              A court’s failure to commence a trial
    within the seventy-day period can result in a dismissal if the
    defendant so moves “prior to trial.”                     
    Id.
     § 3161(a)(2). 6
    On appeal, Saeku contends that the delay resulting from the
    Continuance Order — the seventy days from June 25 to September
    4, 2008 — should not be excluded from the speedy-trial clock. 7
    If that seventy-day delay is excluded, Saeku does not dispute
    that his trial began in a timely manner, within the statutory
    seventy-day period.             Two of the Speedy Trial Act’s exclusions
    are   pertinent       in    evaluating       this    contention.        First,   “[a]ny
    period of delay resulting from the absence or unavailability of
    . . .     an    essential         witness”          is    excluded.         18   U.S.C.
    6
    We are also content to reject the government’s assertion
    that, under our precedent, Saeku’s oral motion to dismiss on
    September 10, 2008, was untimely because it was made after “the
    beginning of the court day when voir dire begins.”        Br. of
    Appellee 37 (emphasis added).    The government misconstrues our
    precedent in that respect.     See United States v. A-A-A Elec.
    Co., 
    788 F.2d 242
    , 246 (4th Cir. 1986) (ruling that, for
    purposes of the Speedy Trial Act, “trial commence[s] at the time
    of voir dire” (emphasis added)).    Instead of deeming the oral
    motion to dismiss untimely, however, we assume that the motion
    was timely made, but reject it for lack of merit.
    7
    The period from September 4, 2008, to September 9, 2008,
    is excluded from the speedy-trial clock on account of the
    pendency of Saeku’s motion to represent himself pro se, filed on
    September 4, 2008. See 
    18 U.S.C. § 3161
    (h)(1)(D).
    14
    § 3161(h)(3)(A).              Second, “[a]ny period of delay resulting from
    a continuance granted by any judge . . . , if the judge granted
    such continuance on the basis of his findings that the ends of
    justice served by taking such action outweigh the best interest
    of the public and the defendant in a speedy trial” is also
    excluded.      Id. § 3161(h)(7)(A).
    Saeku       is     correct      that     the    delay       occasioned         by     the
    Continuance Order cannot be excluded under the ends-of-justice
    exclusion;         the    district      court       did    not     make       any    “express
    findings,” and it could not do so on remand.                                 See Zedner v.
    United States, 
    547 U.S. 489
    , 506-07 (2006).                            We are convinced,
    however, that the delay attributable to the Continuance Order
    was    properly         excluded    under     the     essential-witness             exclusion,
    which     provides        “ample       independent        statutory          authority       for
    excluding [a period] of delay from the speedy trial calculation”
    where    the   ends-of-justice           exclusion        does    not       apply.     United
    States v. Allen, 
    235 F.3d 482
    , 491 (10th Cir. 2000).                                  A trial
    court’s      award       of    a   continuance        under      the    essential-witness
    exclusion need not be accompanied by “specific findings that the
    ends    of   justice       require     the    continuance.”             United      States    v.
    Bourne,      
    743 F.2d 1026
    ,   1031     (4th      Cir.    1984)      (per    curiam).
    Similarly, a trial continuance is not necessarily faulty simply
    because      “the        district       court       fail[ed],          in    granting        the
    continuance, to identify” the specific exclusion being relied
    15
    upon.        United States v. Keith, 
    42 F.3d 234
    , 239-40 (4th Cir.
    1994).
    The       threshold        issue     on        this    point      is    whether     the
    Continuance Order is somehow flawed because it did not expressly
    find that the two government witnesses were both essential and
    unavailable.           Put    succinctly,          however,         the   essential-witness
    exclusion does not require any such findings. 8                           See United States
    v. Garcia, 
    995 F.2d 556
    , 560 (5th Cir. 1993) (excluding period
    of continuance where court “impliedly found” witness essential);
    United States v. Barragan, 
    793 F.2d 1255
    , 1258 (11th Cir. 1986)
    (excluding period of continuance where court “never explicitly
    ruled       on”    continuance           motion,       but    “in     effect    granted     the
    requested continuance” on basis of essential-witness exclusion).
    In adopting the Speedy Trial Act, Congress knew how to require
    express          findings     by     a     district          court.       For    example,     a
    continuance granted pursuant to the ends-of-justice exclusion is
    excludable only if “the court sets forth, in the record of the
    case, either orally in writing, its reasons for finding that the
    ends        of    justice”         justify     the        continuance.           18   U.S.C.
    8
    Notwithstanding our ruling here, we observe                                  that the
    better practice would be for a continuance request to                              expressly
    rely on the essential-witness exclusion, and for the                               court, in
    granting such a continuance, to expressly find                                     that the
    requirements of that exclusion have been satisfied.
    16
    § 3161(h)(7)(A).        By contrast, the essential-witness exclusion
    contains no such requirement.           Moreover, the Continuance Order,
    by explicitly finding that the continuance was granted “for good
    cause shown,” J.A. 97, incorporated the supporting facts of the
    underlying motion.        See United States v. Bruckman, 
    874 F.2d 57
    ,
    61-62 (1st Cir. 1989).         The government’s continuance motion, in
    turn,   clearly        explained     that   two   “key”     witnesses    were
    unavailable.
    Turning      to     the   substance     of   the     essential-witness
    exclusion, its applicability in these circumstances depends on
    two inquiries:      first, whether at least one of the witnesses was
    “essential”; and second, whether the exercise of due diligence
    would have produced each essential witness for trial.                We have
    addressed the second inquiry in our prior decisions, and so we
    begin there.     A witness is “unavailable” where “his whereabouts
    are known but his presence for trial cannot be obtained by due
    diligence.”       
    18 U.S.C. § 3161
    (h)(3)(B).        “Due   diligence”
    requires   merely      “reasonable    efforts,”   not     “maximum   feasible
    diligence.”    United States v. Patterson, 
    277 F.3d 709
    , 711-12
    (4th Cir. 2002).        The unavailability bar is not a high one; in
    one case, a witness’s prior wedding and honeymoon plans rendered
    him unavailable.       See United States v. Meyer, 
    803 F.2d 246
    , 247-
    48 (6th Cir. 1986).        Here, two witnesses were “scheduled to be
    out of the area,” and the record provides no basis for upsetting
    17
    the   court’s    implicit       determination         that     it    would    have     been
    unreasonable to compel them to return for trial as scheduled.
    The continuance motion thus provided a sufficient basis for
    the   district       court     to     find    that     the     two     witnesses       were
    unavailable.         First, prior travel plans can render a witness
    unavailable, and Saeku never challenged the veracity or good
    faith of the representations made in the continuance motion by
    the   United     States      Attorney.             Second,     to     the    extent     the
    continuance motion lacks detail, relief is unwarranted.                             Saeku,
    who was then represented by counsel, contributed to any lack of
    detail   by    not    expressly       opposing       the     motion,       depriving    the
    prosecution of any opportunity to further support its request.
    See   Keith,    
    42 F.3d at 239-40
            (discussing       what    court   called
    “sandbagging” problem, and observing that defendant cannot seek
    dismissal on basis of continuance to which he “affirmatively
    consent[ed],” and where record supports continuance).
    With     respect    to    the    first       inquiry     —     whether    the     two
    witnesses mentioned in the continuance motion were “essential” —
    the district court similarly possessed a sufficient record to
    deem them so.         Although the Act does not define an “essential
    witness,”      the   accompanying       Senate       Judiciary       Committee      report
    explains that the term refers to a witness “so essential to the
    proceeding that continuation without the witness would either be
    impossible or would likely result in a miscarriage of justice,”
    18
    giving as an example “a chemist who has identified narcotics in
    the defendant’s possession.”           S. Rep. No. 93-1021, at 37 (1974).
    In   addressing      this    point,    we    benefit      from    the    guidance     of
    several of our sister circuits, none of which have required the
    witness’s testimony to be so important that conviction could not
    be obtained in its absence.                 See United States v. Miles, 
    290 F.3d 1341
    ,    1350   (11th    Cir.   2002)        (“A   witness    may    be    deemed
    essential      for   the    purposes   of     the    [Speedy      Trial]    Act,   even
    though   the    government     could    obtain       a    conviction     without    his
    testimony.”); Allen, 
    235 F.3d at 491
    ; United States v. Hamilton,
    
    46 F.3d 271
    , 276-77 (3d Cir. 1995) (same); United States v.
    McNeil, 
    911 F.2d 768
    , 773 (D.C. Cir. 1990) (similar); United
    States   v.    Eagle   Hawk,    
    815 F.2d 1213
    ,       1218   (8th     Cir.    1987)
    (similar); United States v. Tedesco, 
    726 F.2d 1216
    , 1222 (7th
    Cir. 1984) (same); United States v. Marrero, 
    705 F.2d 652
    , 656
    (2d Cir. 1983) (similar).
    A well-crafted formulation of the applicable rule is found
    in the Eighth Circuit’s Eagle Hawk decision, which explained
    that
    [w]here a witness is unquestionably important, and the
    government has a good faith belief that it will use
    that witness’s testimony at trial, that witness may be
    deemed “essential” for purposes of the Speedy Trial
    Act. If, however, the witness’s anticipated testimony
    will   be    merely   cumulative,   or   substantially
    irrelevant,   that  witness  should  be   deemed  non-
    essential.
    19
    
    815 F.2d at 1218
    .            The assessment of a witness’s importance
    before    the     witness       testifies            is        necessarily         a     difficult
    endeavor, however, and a reviewing court should not “second-
    guess” the trial court’s determination “based upon hindsight.”
    McNeil, 
    911 F.2d at 773
    .               Whether a witness is essential “is a
    quintessential      question         of    fact.”              Allen,      
    235 F.3d at 491
    .
    Similarly,      questions       of    “whether            ‘a    miscarriage        of        justice’
    ‘would likely result’” implicate the “sound discretion of the
    district judge.”          Marrero, 
    705 F.2d at 657
    .                         In this vein, we
    have previously affirmed a trial court’s determination that a
    witness   was     essential,         deferring        to       its   superior          familiarity
    with the anticipated testimony and its importance.                                     See Bourne,
    
    743 F.2d at 1030-31
    .
    Applying     these       principles                here,      the     district             court
    possessed a sufficient basis to deem either of the two witnesses
    essential.        The   summary       witness’s            testimony        was     expected         to
    break down a vast quantity of records and financial information
    into usable statistics and significantly circumscribe the trial,
    thereby enhancing judicial economy and reducing the likelihood
    that   jurors     might    be    confused            by    voluminous        evidence.             Cf.
    United States v. Wainright, 
    351 F.3d 816
    , 820-21 (8th Cir. 2003)
    (affirming      court’s     decision        to       admit        summary        evidence         where
    defendant    charged       with       interstate               transportation           of     stolen
    property).          Similarly,            the        other        witness,         the        primary
    20
    investigator, would normally be expected to provide important
    testimony.            This       officer      oversaw        many    aspects     of   the
    investigation and had personal knowledge of facts relating to
    Saeku’s fraud scheme.              Notably, Saeku nowhere suggests that the
    evidence of these witnesses could have been obtained some other
    way, cf. Bourne, 
    743 F.2d at 1030-31
    , or that the prosecutor did
    not   have    a   good-faith       belief      that    the    government     would    need
    these       witnesses       at    trial.           Indeed,     the   descriptions      of
    anticipated          testimony         in     the     continuance        motion       were
    sufficiently         detailed      —    the    motion        precisely   (if     briefly)
    described the anticipated testimony of both witnesses and how
    that evidence related to the charges.                      As such, the prosecution
    “show[ed]      how    the    testimony        that    it   expect[ed]    a     particular
    witness will give fits within the overall framework of its case,
    and why that witness’s testimony would be not only useful, but
    essential.”       McNeil, 
    911 F.2d at 774
    . 9

    Although the continuance motion sought a delay “until
    after July 14, 2008,” the Continuance Order continued the case
    until September 2008. Dist. Ct. ECF No. 49, at 2. Nonetheless,
    the entire period of the continuance — and not just the period
    the witnesses were unavailable — is excluded from the speedy-
    trial clock because the statutory phrase “resulting from”
    mandates the exclusion of all time granted pursuant to the
    continuance. See Miles, 
    290 F.3d at 1350-51
    .
    21
    B.
    Finally, we address the prosecutor’s entreaty to the jury
    in his closing argument that it should not consider Saeku’s race
    or   immigration      status.        To        prevail       on   this     unpreserved
    contention of error, Saeku must meet the plain error standard of
    United States v. Olano, which requires the presence of (1) an
    error,   that    is   (2)   plain,   and        (3)    affects      the    defendant’s
    “substantial rights.”        
    507 U.S. 725
    , 732 (1993).                   Even then, we
    will grant relief only if we determine, in our discretion, that
    “the error seriously affects the fairness, integrity or public
    reputation of judicial proceedings.”                   
    Id.
     (internal quotation
    marks and alterations omitted).                Indeed, relief under the plain
    error test “demand[s] strenuous exertion.”                         United States v.
    Dominguez Benitez, 
    542 U.S. 74
    , 82 (2004).
    The     established    principles          governing         the    propriety   of
    challenged      prosecutorial    remarks          to     a    jury      are   likewise
    demanding.      To prevail, a defendant “must show [1] that the
    remarks were improper and [2] that they prejudicially affected
    the defendant’s substantial rights so as to deprive [him] of a
    fair trial.”      United States v. Adam, 
    70 F.3d 776
    , 780 (4th Cir.
    1995) (internal quotation marks omitted).                         To properly gauge
    whether a defendant suffered such prejudice, we must examine
    several factors, including the following:
    22
    (1) the degree to which the prosecutor’s remarks have
    a tendency to mislead the jury and to prejudice the
    accused; (2) whether the remarks were isolated or
    extensive; (3) absent the remarks, the strength of
    competent proof introduced to establish the guilt of
    the accused; and (4) whether the comments were
    deliberately   placed  before    the jury  to  divert
    attention to extraneous matters.
    
    Id.
     (internal citations omitted).                   Importantly, we also evaluate
    “(5) whether the prosecutor’s remarks were invited by improper
    conduct of defense counsel and (6) whether curative instructions
    were given to the jury.”             United States v. Wilson, 
    135 F.3d 291
    ,
    299 (4th Cir. 1998) (internal quotation marks omitted).
    To begin with, it is not at all clear that the remarks
    challenged by Saeku were improper.                  In United States v. Alzanki,
    the   First   Circuit       relied     in    part    on    a    prosecutor’s        plea      in
    closing   argument        that   the    jury       not    consider        the    defendant’s
    ethnicity and nationality to conclude that the risk of prejudice
    resulting     from    the    jury’s    knowledge          of    those     aspects       of   the
    defendant’s background had, in fact, been ameliorated.                                  See 
    54 F.3d 994
    , 1007 (1st Cir. 1995).                   As in Alzanki, the prosecutor’s
    remarks in this case were not inflammatory and did not appeal to
    prejudice; rather, they took the form of a plea not to consider
    irrelevant     or    impermissible          grounds.           Moreover,        there   is    no
    indication that the prosecutor, by isolated references in his
    lengthy closing argument, sought to invite adverse attention to
    Saeku’s     race     or     immigration       status;          on   the    contrary,         the
    23
    prosecutor’s       references          were     occasioned         by   Saeku’s        previous
    injection of those issues into the trial.
    Nevertheless,            any    discussion       of    a     defendant’s         race   or
    immigration status before a criminal jury is a sensitive issue.
    Such references — even this prosecutor’s sincere plea for the
    jury not to consider irrelevant matters that Saeku himself first
    brought up — are not to be encouraged.                             In United States v.
    Young,     the     Supreme           Court    addressed          the    “all     too     common
    occurrence in criminal trials” where “the defense counsel argues
    improperly, provoking the prosecutor to respond in kind, and the
    trial    judge         takes    no      corrective      action”         —      warning     that
    “[c]learly two improper arguments . . . do not make for a right
    result.”         
    470 U.S. 1
    ,     11    (1985).        As    the    Court    explained,
    “[p]lainly, the better remedy” is for the trial court “to deal
    with the [defense counsel’s] improper argument . . . promptly
    and thus blunt the need for the prosecutor to respond,” or for
    the prosecutor to “object[] to the . . . improper statements
    with a request that the court give a timely warning and curative
    instruction to the jury.”                    
    Id. at 13
    .          The Court also pointed
    out   that,      “[a]t    the        very    least,”   the       prosecutor      could     have
    sought a bench conference out of the jury’s presence to suggest
    an appropriate curative instruction.                         
    Id. at 13-14
    .              Heeding
    Young, there were better ways to address Saeku’s references to
    his race and immigration status.
    24
    Ultimately, however, we need not definitively resolve the
    propriety of the prosecutor’s remarks, because they were not
    prejudicial.      The evidence of Saeku’s guilt was overwhelming,
    and the challenged statements were few in number and made in
    passing during a protracted closing argument.            Additionally, the
    prosecutor merely cautioned the jury that it was sworn to render
    its verdict solely on the facts and the law, and did so only
    after Saeku had injected his race and immigration status into
    the trial.     Cf. United States v. Roach, 
    502 F.3d 425
    , 435-36
    (6th Cir. 2007) (finding no reversible error where prosecutor’s
    closing    argument    referred   to   race   and   immigration   status   of
    victims,     because     remarks,      although     “condemn[able],”   were
    isolated, did not encourage jury to render verdict on improper
    ground, and were in response to defense counsel’s own “race-
    baiting”).     In sum, the failure to follow the better practices
    outlined in Young is not necessarily error, and, even assuming
    error, Saeku clearly suffered no prejudice.
    IV.
    Pursuant to the foregoing, we affirm the judgment of the
    district court.
