    Appeal from the United States District Court
    for the Southern District of Florida
    _______________________
    (June 6, 2018)
    Before WILLIAM PRYOR, JILL PRYOR, and BLACK, Circuit Judges.
    WILLIAM PRYOR, Circuit Judge:
    Wenxia Man appeals her conviction and sentence for conspiracy to export
    defense articles without a license or written approval in violation of the Arms
    Control Export Act, 
    22 U.S.C. § 2778
    ; see also 
    22 C.F.R. §§ 121.1
    , 123.1, 127.1.
    Case: 16-15635     Date Filed: 06/06/2018   Page: 2 of 44
    Her appeal requires us to decide whether sufficient evidence supports her
    conviction, including the decision of the jury to reject her defense of entrapment;
    whether the district court abused its discretion in admitting evidence of the
    conspirators’ communications; whether her sentence is procedurally and
    substantively reasonable; and whether the government failed to disclose
    exculpatory evidence, Brady v. Maryland, 
    373 U.S. 83
     (1963). Between 2011 and
    2013, Man participated in a series of discussions with Xingsheng Zhang, a Chinese
    operative; Jerry Liu, an undercover agent with the Department of Homeland
    Security; and an unnamed, unindicted person about how to purchase and export to
    China military aircraft engines, a military drone, and related technical data.
    Although the sale never occurred, the United States charged Man with conspiring
    to violate the Act. At trial, Man contended that insufficient evidence established a
    conspiracy and that she was entrapped. She also unsuccessfully objected to the
    admission of some of the conspirators’ communications as either hearsay or prior
    bad acts. The jury convicted Man, and the district court sentenced her to 50 months
    of imprisonment after rejecting her argument that she was entitled to a downward
    adjustment for her minimal role in the scheme. On appeal, Man reiterates her
    earlier arguments and argues for the first time that the district court erroneously
    sentenced her on the basis of her national origin and that the government failed to
    provide her with a copy of an email. We affirm.

    I. BACKGROUND
    We divide the background in two parts. First, we describe the facts. Second,
    we explain the procedural history.
    A.    The Facts
    Wenxia Man is a resident and citizen of the United States who was born in
    China. She and her husband owned a company that produced electronic
    components for military applications. But her interest in military hardware went
    beyond this legitimate business.
    On February 27, 2011, Man received an email from an account with the
    name “hrkj2006” that asked her about engines used in military aircraft. The email
    read as follows:
    Inquiry. Hi, Sister. Can you check if you are able to find the following
    [aircraft engines]: Manufacturer Lockheed Martin, Model 1, F100 Pratt &
    Whitney 229 or F110 General Electric 129. Two, F119 Pratt & Whitney 100
    or F119 Pratt & Whitney 119, three pieces each.
    Two days later, Man inquired about these engines in an email to Matthew
    McCauley, who worked for an international electronic sales company that
    distributed capacitors manufactured by Man’s company. McCauley responded that
    he could “get [her] the[] engines, but [her] customer w[ould] need to pick them up
    in the United States.” Man sent a reply email that provided a revised list of
    engines. She also stated in the email that, “[i]f there [was] any export problem,
    [they would] have to give up.”
    3
    Case: 16-15635      Date Filed: 06/06/2018   Page: 4 of 44
    McCauley reported this exchange to the Department of Homeland Security.
    At the direction of the Department, McCauley emailed Man on September 13,
    2012. He told her he had located a seller who would allow Man’s “customer [to]
    pick up the engines outside the United States.” Man replied that she was “glad to
    hear from [McCauley]” and would speak with her customer. The next day, Man
    confirmed to McCauley that her “customer . . . still need[ed] th[e] engine[s],” and
    she asked if “it [was] possible to [ship the engines to] Hong Kong.”
    Man later gave McCauley more information about the nature and purpose of
    her inquiries. She informed him that the Chinese government would provide the
    money for the sale, that her customer had “made similar transaction[s] with
    Russia,” and that she would receive a “commission” when the deal closed. But she
    refused to give McCauley additional details because “the procedure [was] very
    complicated and risky.” And when Man asked McCauley for additional
    information about the seller—including whether “he [was] Chinese”—she stressed
    that McCauley “need[ed] to make [sure that] the seller is not from [the Federal
    Bureau of Investigation] because . . . sometimes the [Bureau] officer[s] disguise[]
    [themselves as] seller[s] to find spy activities.”
    The “seller,” Jerry Liu, was an undercover agent with the Department of
    Homeland Security. McCauley provided Man with Liu’s phone number on
    September 20, 2012, and Man called Liu “within a few hours.” After Liu
    4
    Case: 16-15635      Date Filed: 06/06/2018     Page: 5 of 44
    confirmed to Man that he was “Chinese,” Man explained that she was looking for
    military engines.
    Man and Liu discussed legal obstacles to the export of the engines. Liu
    informed Man that he “[u]sually . . . need[ed] a license to send [the engines]
    outside” of the country and that a license for export to China “might be a little
    difficult.” He also told her that she should “try to get a license first,” but that “[i]f
    [that] doesn’t work, then [they could] talk.” Man quickly responded that she would
    “not get this license.” She explained that the “[United States] prohibits sending
    [these kinds of engines] to China” and that this barrier was why her “friends in
    mainland China” “need[ed] [her] to do it.” Liu then proposed sending the engines
    “to a third country[,] and then from [there], selling abroad to China.” Man agreed
    to this plan after underscoring that “[n]o mistake[s] [were] allowed.”
    Man provided Liu with the name of her customer, Xingsheng Zhang, and
    Zhang’s phone number and email address. She explained to Liu that she “was
    introduced [to Zhang] through another friend who smuggles arms to China.” Man
    also reiterated that her clients were “scared of any mistake,” and Liu confirmed
    that “[they] would be in trouble” “[i]f [they] found the wrong person.” And she
    reminded Liu that they had “to be very careful” because “any mistakes” would be
    “[v]ery troublesome.”
    5
    Case: 16-15635     Date Filed: 06/06/2018    Page: 6 of 44
    Man’s fears of legal trouble reemerged in later conversations between her
    and Liu. For example, she told Liu that, “if there were no embargo . . ., [her
    clients] would not need . . . [their] help.” She also explained that she and
    McCauley “stopped” their earlier dealings because she “really [didn’t] want to
    touch anything that is in violation of the law” and “[didn’t] have any solution” for
    “get[ting] [the engines] out of the [United States].” Despite these concerns, Man
    and Liu continued to discuss the price of the engines, how to ship through a third-
    party country, and Man’s “commission” for the sale.
    Liu then sent an email in English to Zhang, Man’s customer. He did not
    copy Man on the email, so he called her to ask whether Zhang could understand
    English. Man informed Liu that Zhang had received the email but that “[h]is
    English [was] not good.” Man also told Liu that Zhang had additional technical
    questions about the engines, and Liu promised to call Zhang shortly. Man
    suggested that Liu should try to call in the morning because of Zhang’s schedule.
    And she again expressed concern about how to “hide” the engines and “get them
    out” of the country. In the light of these difficulties, she told Liu that Zhang might
    be satisfied with the “technical materials” instead of the engines.
    After Zhang confirmed that he was interested in the technical “drawings and
    information” for the engines, Man and Liu discussed financial terms, Man’s
    “profit,” and how to ship through a third-party country. In one conversation, Man
    6
    Case: 16-15635      Date Filed: 06/06/2018    Page: 7 of 44
    suggested that she thought that “shipping to a third country instead of shipping
    directly to China” was “legal.” But Liu replied that he had done “research” and
    found that “ship[ment] . . . to China is totally illegal” and that “ship[ping] this stuff
    to China is a violation of the law.” He also explained that his “agent” would
    “require some payment in order to protect himself” because he would be “taking
    [a] risk.” Man again suggested that a third-party shipment would be “legal.” But
    she then rejected Liu’s suggestion that she handle the transaction through her
    corporate bank account because “[a] deposit of a large sum is troublesome.” She
    also instructed Liu not to tell his supplier that the engines are “going to China” and
    that “the information that this stuff is shipping to China should stop with [him]”
    “[b]ecause there are many federal agents investigating.” And she agreed with Liu
    that they were “tak[ing] on the highest risk” because they “live[d] in the [United
    States].” Finally, she directed Liu to not “get [her] involved” “[i]f [he] g[o]t
    caught.”
    Man also provided Liu with additional detailed information about Zhang.
    Man explained that Zhang was “working for the Chinese military[,] sort of like a
    tech spy,” and that he was “trying to find [advanced technology] to provide
    shortcuts for our country.” She also told Liu that Zhang worked for the “China
    National Aviation Corporation” and that she was hoping to expand her legitimate
    electronics business into China through Zhang.
    7
    Case: 16-15635     Date Filed: 06/06/2018    Page: 8 of 44
    Later communications between Liu and the individual conspirators followed
    the same pattern. Liu and Zhang would discuss the engines, technical data, pricing,
    and shipment details, and Liu then would call Man to update her and to discuss
    prices, her compensation, and the legal risks of their plan. Liu also emailed Man a
    “business plan” that specified that the engine “distributor will not know the final
    destination of the engines” and that “the buyer will not know the identity of the . . .
    distributor.” Liu and Man later discussed this “business plan” and the technical
    details of the engines over the phone.
    Man and Zhang also expressed strong interest in military hardware other
    than the engines. At one point, Man informed Liu that Zhang “need[ed] material
    information [about a] drone aircraft.” Liu then spoke with Zhang, who confirmed
    that he wanted “the most advanced” “drone aircraft.” After Liu again spoke to
    Man, he informed Zhang that he could procure a MQ-9 Reaper drone, but that
    shipment to China was “totally prohibited” and “a crime in the [United States].”
    Zhang responded that he would “think about other means” to get the drone.
    Liu reported this conversation to Man and asked her to assist in translating
    technical information. He also confirmed Man’s belief that that the drone was
    “prohibited for export to China.” Despite this obstacle, Man confirmed that her
    buyer was interested in obtaining both the actual drone and its “software” and
    “mathematical model.” Man explained that the software was necessary to “modify”
    8
    Case: 16-15635     Date Filed: 06/06/2018   Page: 9 of 44
    the drone because, if China produced an “identical” drone, “people would know
    right away that [they] stole it, which is not allowed.”
    Liu next emailed Zhang a “false flight schematic” for the drone, and Zhang
    demanded additional data. Liu also sent the fake schematic to Man. He later called
    her to review the schematic and told her that, “by [his] sending out this page,” “all
    of [them] [had] . . . committed a crime.”
    Man and Liu also discussed purchasing a military decoy aircraft
    manufactured in Sweden. In a phone call, Man explained that Zhang was interested
    in “buying or getting a quote for something like [the decoy],” and she sent a
    follow-up email with the specific items sought by Zhang. Man and Liu again spoke
    over the phone, and Liu stated that he would “try to contact people [he] kn[e]w in
    Europe to see if they [had] any contact with th[e] [manufacturer].” Man also
    suggested that Liu “could try calling” Zhang about the decoy, and she
    recommended that Liu do so “in the morning [because Zhang] . . . is a night owl.”
    Man and Liu also discussed having Man’s “company sponsor [Zhang] so he could
    come [to the United States].”
    The sale never occurred. Zhang expressed concerns about how quickly Liu
    could procure the goods, about whether Liu could provide full information about
    the drone, and about the price of the drone. Liu and Man discussed these obstacles
    and payment terms, and Man suggested that she would attempt to persuade Zhang
    9
    Case: 16-15635        Date Filed: 06/06/2018   Page: 10 of 44
    to close the deal. She also discussed using “her company to sponsor either . . .
    Zhang or [an] engineer[] to come over on [a] visa [and] examine th[e] documents,”
    even though she thought that viewing the documents was “illegal.” And she told
    Liu that Zhang “was hesitant to talk much over the phone [because] phone calls in
    the [United States] are under surveillance.” She also expressed her own concerns
    about the deal and explained that she had “lost so much money.” Finally, on June
    20, 2013, Zhang told Liu that, although he was “eager[]” to make the deal, he was
    unconvinced that Liu could “deliver” and that the sale was off. Liu arranged to
    meet Man in person on September 1, 2015, and federal agents arrested Man at the
    meeting.
    B.      Procedural History
    The United States charged Man and Zhang with conspiracy to export
    defense articles without a license, but it was unable to apprehend and prosecute
    Zhang. The parties stipulated that the Arms Control Export Act, 22 U.S.C § 2778,
    applied to the aircraft engines and the drone at the time of Man’s actions, that a
    “license . . . was required to export any of these items,” and that neither Man nor
    Zhang, “[n]or any company or entity associated with [them,] had a license.” And
    Man did not assert that she planned to obtain a license.
    At trial, the government presented testimony from Liu, who explained his
    communications with the conspirators. He also testified that the United States has
    10
    Case: 16-15635     Date Filed: 06/06/2018     Page: 11 of 44
    maintained an arms embargo against China for decades, see 
    22 C.F.R. § 126.1
    (a)
    & (d)(1), and that China uses nationals “living in the [United States] who have
    access to [military] goods . . . to procure” these items.
    The government also introduced several emails and transcripts of phone
    conversations between Man, Zhang, Liu, and an unnamed, unindicted third party.
    Man objected to three pieces of evidence, but the district court overruled her
    objections.
    First, Man objected that the transcript of a phone call between Liu and
    Zhang was hearsay and that Zhang’s statements were not admissible under the
    exception for the statements of fellow conspirators. See Fed. R. Evid. 801(d)(2)(E).
    This conversation included discussion of the engines, shipment through a third-
    party country, and Man’s earlier conversations with Zhang. The district court
    overruled Man’s objection after it explained that Zhang’s statements to Liu in the
    conversation were “made to further the objectives of the conspiracy.”
    Second, Man argued that three emails sent to Man from an email account
    with the name “hrkj2006” were inadmissible hearsay because the government
    failed to identify the owner of the email address. The first email from the mystery
    address asked Man for an update on “the project.” It also was part of a larger email
    thread that included an email from Man with the subject line “Forward: Mr.
    Zhang’s Order” and an email from Man that discussed the plan to “obtain the
    11
    Case: 16-15635     Date Filed: 06/06/2018    Page: 12 of 44
    technical information.” The second email sent from the unknown account to Man
    asked her to “check if [she was] able to find the [engines].” And the third email
    from the unknown account made a slight modification to the earlier list of engines.
    The district court overruled Man’s objections and found that the owner of the
    “hrkj2006” address was an unindicted conspirator after the government established
    that the initial email Man sent to Liu with Zhang’s “contact information” also
    copied the “hrkj2006” account.
    Third, Man objected that communications between her and Liu about a
    decoy aircraft produced by a Swedish manufacturer were irrelevant and
    inadmissible under Federal Rule of Evidence 404(b) because the government had
    not charged her for the attempt to obtain the Swedish decoy. The district court
    overruled her objection and explained that this evidence “show[ed] the ongoing
    relationship” between the conspirators and “reflect[ed] the participation of [Man].”
    Shortly after it admitted this evidence, the district court instructed the jury that
    “[n]either . . . Man nor . . . Zhang [were] accused of conspiring to export [the
    decoy]” and that the jury “should not speculate whether such an act would have
    been legal or illegal.”
    On the third day of trial, the government informed the district court that Man
    had sent text messages in Chinese to Liu during the trial. The messages were
    largely nonsensical, but they made references to “China” and “sanction[s].” The
    12
    Case: 16-15635     Date Filed: 06/06/2018    Page: 13 of 44
    district court ruled that Man had violated the terms of her pretrial release and
    remanded her into custody.
    Man did not testify. Her attorney argued that insufficient evidence
    established that Man joined a sufficiently definite conspiracy willfully to violate
    the Act. Counsel also contended that Man was entrapped by the government, and
    the district court gave an entrapment instruction. In support of this theory, Man
    called Kenneth Wallace, an acquaintance of Man who worked for the company that
    manufactures the MQ-9 drone. Wallace testified that Man never approached him
    about the drone. But the jury rejected Man’s arguments and convicted her.
    At sentencing, Man requested both a downward adjustment and downward
    departure. First, Man asserted that she was a “minimal participant,” United States
    Sentencing Guidelines Manual § 3B1.2(a) (Nov. 2015), because she “was a pawn
    in [a larger] scheme” to steal American technology. The district court rejected this
    argument after finding that “Man was much more than a referral source” and was
    “essential and vital” to the scheme. Second, she asserted that she suffered from
    “significantly reduced mental capacity” at the time of the offense. Id. § 5K2.13.
    Man pointed to a psychiatric report that found she had a mental illness and
    underscored that her decision to text Liu during the trial was “very bizarre
    behavior.” The district court rejected this argument after it found that “Man asked
    13
    Case: 16-15635     Date Filed: 06/06/2018    Page: 14 of 44
    specific questions, made repeated requests for assurances, [and] had clear follow-
    up[s]” during “[t]he period of time that [she] was involved in the [conspiracy].”
    Man also objected to a line in the sentencing memorandum submitted by the
    government that stated, “[Man] should have thought about her family before she
    put money and nationalism before them.” She contended that the reference to
    “nationalism” erroneously suggested that the district court should impose a
    sentence based on Man’s national origin. Contra id. § 5H1.10. The district court
    “reject[ed Man’s contention] that . . . [her] national origin ha[d] been made an
    issue” and explained that “[h]er actions [were] the relevant factor.” It also
    mentioned both that Man acted out of a “commitment to help the Republic of
    China” and that she was “faithful to [her] native country,” but Man failed to object
    to these comments. The district court then sentenced Man to 50 months of
    imprisonment.
    II. STANDARDS OF REVIEW
    Several standards of review govern this appeal. “We review the sufficiency
    of the evidence de novo, viewing the evidence in the light most favorable to the
    government” and making “[a]ll reasonable inferences and credibility choices . . . in
    favor of the government and the jury’s verdict.” United States v. Garcia, 
    405 F.3d 1260
    , 1269 (11th Cir. 2005). We also review de novo whether the evidence entitled
    a jury to reject a defense of entrapment. See United States v. Isnadin, 
    742 F.3d 14
    Case: 16-15635     Date Filed: 06/06/2018   Page: 15 of 44
    1278, 1303 (11th Cir. 2014). “We review evidentiary rulings for abuse of
    discretion.” United States v. Wilk, 
    572 F.3d 1229
    , 1234 (11th Cir. 2009). With
    regard to a sentence, we review de novo both “the district court’s legal
    interpretation of the [S]entencing [G]uidelines” and “the district court’s application
    of the [S]entencing [G]uidelines to the facts.” United States v. Cubero, 
    754 F.3d 888
    , 892 (11th Cir. 2014). But we review for clear error the “denial of a role
    reduction” because this is a factual finding. United States v. Cruickshank, 
    837 F.3d 1182
    , 1192 (11th Cir. 2016). Although we ordinarily review the substantive
    reasonableness of a sentence for abuse of discretion, see Cubero, 754 F.3d at 892,
    we review only for plain error when the defendant fails to make a timely objection,
    see United States v. Rodriguez, 
    627 F.3d 1372
    , 1380 (11th Cir. 2010). The same
    standard applies when a defendant fails to raise a timely objection under Brady.
    See United States v. Bender, 
    290 F.3d 1279
    , 1284 (11th Cir. 2002).
    III. DISCUSSION
    We divide our discussion in four parts. First, we explain that sufficient
    evidence establishes that Man conspired with Zhang willfully to violate the Act
    and that the evidence entitled the jury to reject Man’s defense of entrapment.
    Second, we explain that the district court did not abuse its discretion when it
    admitted evidence of the conspirators’ communications. Third, we explain that
    Man’s sentence is procedurally and substantively reasonable. Fourth, we explain
    15
    Case: 16-15635      Date Filed: 06/06/2018    Page: 16 of 44
    that no plain error occurred when the government failed to disclose an email
    referenced in a conversation between Man and Liu.
    A.     Sufficient Evidence Supports Man’s Conviction.
    The Act empowers “the President . . . to control the import and the export of
    defense articles,” “to designate . . . items which shall be considered as defense
    articles,” and “to promulgate regulations for the . . . export of such articles.” 
    22 U.S.C. § 2778
    (a)(1). When the President has determined that an item is a “defense
    article[],” a private individual ordinarily may not export it from the United States
    without a license or written approval from the government. 
    Id.
     § 2778(b)(2); see
    also 
    22 C.F.R. §§ 121.1
    , 123.1, 127.1. As the parties stipulated, the list of
    designated “defense articles” included the engines, drones, and technical data
    charged in the indictment at the time of Man’s conduct. See generally 
    22 C.F.R. § 121.1
    . And the Act imposes criminal penalties on “[a]ny person who willfully
    violates” its prohibitions. 
    22 U.S.C. § 2778
    (c).
    To establish a conspiracy, the government must prove “(1) [an] agreement
    between two or more persons to achieve an unlawful objective; (2) knowing and
    voluntary participation in that agreement by the defendant; and (3) an overt act in
    furtherance of the agreement.” United States v. Broughton, 
    689 F.3d 1260
    , 1277
    (11th Cir. 2012). “[T]here can be no . . . conspiracy with a government informer
    who secretly intends to frustrate the conspiracy,” but a “government informer[]
    16
    Case: 16-15635     Date Filed: 06/06/2018    Page: 17 of 44
    may serve as the connecting link between []conspirators.” Sears v. United States,
    
    343 F.2d 139
    , 142 (5th Cir. 1965). “Proof is not required that the defendant had
    knowledge of all the details of the conspiracy; the defendant need only have
    knowledge of the essential objective of the conspiracy.” United States v. Elledge,
    
    723 F.2d 864
    , 866 (11th Cir. 1984) (citation and internal quotation marks omitted).
    And the government may rely on “circumstantial evidence, such as inferences from
    the conduct of the alleged participants or from circumstantial evidence of a
    scheme.” 
    Id. at 865
     (citation and internal quotation marks omitted). But “[w]here
    the government relies on circumstantial evidence, reasonable inferences, and not
    mere speculation, must support the jury’s verdict,” United States v. Klopf, 
    423 F.3d 1228
    , 1236 (11th Cir. 2005) (citation and internal quotation marks omitted),
    although “[i]t is not necessary for the government to disprove every reasonable
    hypothesis of innocence,” United States v. Mieres-Borges, 
    919 F.2d 652
    , 656 (11th
    Cir. 1990) (citation and internal quotation marks omitted).
    Man makes three arguments that the government failed to prove that she
    conspired to violate the Act. First, she argues that she never “enter[ed] into a[]
    conspiratorial agreement” with “Zhang or anyone else to obtain, purchase[,] or
    export defense articles.” Second, she asserts that she did not conspire to “willfully
    violate[] the [Act].” Third, she contends that the evidence establishes that she was
    entrapped. None of these arguments is persuasive.

    1.    Sufficient Evidence Establishes an Agreement Between Man and Zhang.
    “A complete[,] detailed agreement is not necessary to convict persons of
    conspiracy.” Elledge, 
    723 F.2d at 868
    . On the contrary, “a plan may be pretty half-
    baked and still be a criminal conspiracy if the intentions of the participants are
    illicit.” United States v. Jones, 
    765 F.2d 996
    , 1002 (11th Cir. 1985). For example,
    in Elledge we upheld a conviction for a conspiracy to smuggle drugs into the
    United States by airplane despite evidence that the conspirators had not yet agreed
    on “the precise arrangements for the importation.” 
    723 F.2d at 868
    . We
    acknowledged that important elements of the plan, such as “a source for the
    marijuana, security for the operation, a place to land or drop off the marijuana, a
    distribution system[,] and financial backers,” were “at best uncertain.” 
    Id.
     Indeed,
    the “sponsors backed out” and the defendant “never made final arrangements with
    the pilot to have the drugs imported.” 
    Id.
     Despite these considerable difficulties,
    we determined that the defendant had reached a sufficiently “detailed agreement”
    with his conspirators. Id.; accord 
    id. at 869
    . We explained that he had, among other
    things, “contacted financial backers,” “me[t] with the pilot,” and “had begun to
    discuss the details of the scheme.” 
    Id. at 869
    . And we underscored that the question
    whether a “plan [is] . . . ultimately completed or executed” is irrelevant to whether
    the defendants have reached an unlawful agreement. 
    Id.
     Indeed, even “sheer
    impossibility is no defense.” Jones, 
    765 F.2d at 1002
    .
    18
    Case: 16-15635     Date Filed: 06/06/2018    Page: 19 of 44
    To be sure, if alleged conspirators discuss only a “specially tailored
    proposal[]” that is wholly contingent on the participation of a third party, the
    negotiations do not ripen into a conspiracy until the necessary third party joins the
    conspiracy. 
    Id. at 1003
    ; see also 
    id. at 1001
    . For example, in Jones we held that
    conversations between the defendant and prospective accomplices about how to
    import marijuana into the United States by helicopter did not produce an
    “agreement” when the plan was fully dependent on the participation of an
    undercover government agent who never agreed to the plan. 
    Id.
     at 1002–03.
    Although the putative conspirators reached an “understanding” that they would
    take further steps such as “acquir[ing] the necessary helicopters” and “mov[ing]
    the contraband cargo,” the record established that the plan would go forward only
    if the government agent “acquiesced, . . . contributed the necessary funds, and
    satisfied them . . . that he was truly convinced and committed.” 
    Id. at 1002
    . And
    the agent failed to do so. Indeed, no evidence suggested that the alleged
    conspirators “agreed to submit to anyone proposals other than the ones they
    submitted to [the agent]” or “ever even exchanged two words after [the agent
    rejected the proposals].” 
    Id. at 1003
    . In the absence of evidence that the would-be
    conspirators had formed a “complete plan looking for no more than a [final
    participant],” 
    id. at 1002
    , or “would have maintained any kind of partnership or
    joint venture except the one [that they] propos[ed] to [the agent],” we held that “the
    19
    Case: 16-15635    Date Filed: 06/06/2018    Page: 20 of 44
    verdict [could] not stand,” 
    id. at 1003
    . But we cautioned that our holding was
    limited to “very fact-specific” circumstances, 
    id. at 1001
    , where a defendant only
    “partial[ly] accept[s] [a] proposal[]” that “stat[es] a precondition not met,” 
    id. at 1003
    .
    Man contends that, “[b]ecause all of . . . Liu’s proposals were rejected by
    Zhang, the parties never advanced beyond mere discussions” or “ever finalized” an
    agreement. She argues that the evidence “[a]t best [shows that she] and Zhang
    agreed to submit inquiries about products” and “negotiate an agreement,” neither
    of “which is . . . an agreement for purposes of conspiracy.” And she asserts that an
    “attempt to arrange a purchase” is not “an agreement to carry out an illegal act.”
    We disagree.
    Sufficient evidence establishes that Man and Zhang agreed to export
    unlawfully the items charged in the indictment and that this agreement was not
    wholly conditioned on Liu’s participation. To be sure, Zhang never reached a final,
    definite agreement with Liu. But the record supports the reasonable inference that
    Man and Zhang reached an independent agreement to acquire the engines and
    drones from any available source and that the duo “would have maintained [a]
    partnership or joint venture” in addition to “the one [that they] propos[ed] to
    [Liu].” 
    Id. at 1003
    . Indeed, the search for a supplier began before Man and Zhang
    became aware of Liu. After Man received an email from the “hrkj2006” account
    20
    Case: 16-15635      Date Filed: 06/06/2018    Page: 21 of 44
    that instructed her to locate military engines, she aimed her initial inquiries at
    McCauley. And when McCauley recommended Liu, Man readily redirected her
    efforts.
    The conspirators’ statements when the deal fell apart also evidence that Man
    and Zhang intended to find an alternative participant for their scheme. Zhang told
    Liu that he remained “very eager[] . . . to do [the deal]” and did not “have any
    financial issues.” He explained that he did not intend to make a purchase from Liu
    because he was “concerned that [Liu] could not deliver in the condition [he]
    want[ed].” Indeed, Zhang suggested in the same conversation that he might be
    willing to negotiate new terms if Liu would meet him in Taiwan or Hong Kong.
    This persistence was sufficient to allow a reasonable jury to infer that Man and
    Zhang’s agreement to obtain the drones and engines was not wholly dependent on
    Liu and that the conspirators had “agreed to submit to [different potential sellers]
    proposals other than the ones they submitted to [Liu].” 
    Id.
     In short, the evidence of
    extensive negotiations and plotting establishes far more than a “half-baked” plan,
    and that Man and Zhang’s attempt to acquire the contraband from Liu ultimately
    proved “impossib[le] is no defense.” 
    Id. at 1002
    .
    Evidence of an ongoing and close relationship between Man and Zhang
    during their search for a supplier also supports the inference that they reached an
    independent and sufficiently definite agreement to export the relevant items
    21
    Case: 16-15635     Date Filed: 06/06/2018     Page: 22 of 44
    unlawfully. Man brokered the connection between Liu and Zhang and provided
    Liu with Zhang’s email address and phone number. And in her discussions with
    Liu, Man frequently relayed inquiries and demands from Zhang, such as his
    interest in the drone and specific engine models. She also provided Liu with
    detailed information about Zhang, such as that he worked for the Chinese military,
    was a “tech[nology] spy,” and was “a night owl.” And she told Liu about Zhang’s
    concern that “the phone calls in the [United States were] under surveillance.” A
    reasonable jury could find that Liu was not a necessary part of Man and Zhang’s
    relationship and agreement.
    2.     Sufficient Evidence Establishes that Man and Zhang Conspired Willfully To
    Violate the Act.
    The Act punishes only “willful[]” violations, 
    22 U.S.C. § 2778
    (c), and this
    element of mens rea also applies to a conspiracy to violate the Act, see United
    States v. Davis, 
    583 F.2d 190
    , 192 (5th Cir. 1978) (“To sustain a conviction on a
    charge of conspiracy to commit an offense against the United States[,] the
    government must prove at least the degree of criminal intent necessary for the
    substantive offense . . . .”). To establish a “willful[]” violation of the Act, the
    government must prove that a conspirator actually “knew that it was unlawful to
    export the [items]” and “intentionally violated [the] known legal duty not to export
    [them].” United States v. Adames, 
    878 F.2d 1374
    , 1377 (11th Cir. 1989); see also
    Davis, 
    583 F.2d at 193
    . Evidence that a defendant merely “was aware of the
    22
    Case: 16-15635     Date Filed: 06/06/2018   Page: 23 of 44
    generally unlawful nature of her actions” is insufficient. Adames, 
    878 F.2d at 1377
    ;
    cf. Etheridge v. United States, 
    380 F.2d 804
    , 807 (5th Cir. 1967) (explaining that
    the government satisfied its burden to prove that the defendants actually “knew it
    was unlawful to export [the contraband] from the United States”); United States v.
    Wieschenberg, 
    604 F.2d 326
    , 331 (5th Cir. 1979) (“[T]he government must prove
    that the defendants agreed to and specifically intended to export without a license
    [a restricted item].”). This heightened element of mens rea applies “[b]ecause the
    items covered by the [Act] are spelled out in administrative regulations and include
    items not known generally to be controlled by the government.” Adames, 
    878 F.2d at 1377
     (quoting Davis, 
    583 F.2d at 193
    ).
    The government contends that the Supreme Court has abrogated our
    precedents in Davis and Adames and that it needed to prove only that Man was
    aware that her actions were “generally unlawful.” In Bryan v. United States, the
    Supreme Court held that a law that punishes individuals who “willfully engag[e] in
    the business of dealing in firearms [without a license]” does not require the
    government to prove that the defendant “was aware of the federal law.” 
    524 U.S. 184
    , 189 (1998); accord 
    id.
     at 195–96. The Supreme Court explained that the
    statute requires that the government establish only that the defendant “acted with
    knowledge that his conduct was unlawful.” 
    Id. at 192
     (quoting Ratzlaf v. United
    States, 
    510 U.S. 135
    , 137 (1994)). And we later held in United States v. Starks that
    23
    Case: 16-15635     Date Filed: 06/06/2018    Page: 24 of 44
    the term “willfully” in the anti-kickback statute, 42 U.S.C. § 1320a-7b(b), requires
    the government to prove only that a defendant knew that his conduct was generally
    unlawful, and not that he specifically knew that his actions violated the statute. 
    157 F.3d 833
    , 837–39 (11th Cir. 1998). We disagree with the government.
    Bryan did not abrogate our holding in Adames that “aware[ness] of the
    generally unlawful nature of [one’s] actions” is insufficient under the Act and that
    the government must instead prove a violation of “a known legal duty.” 
    878 F.2d at 1377
    . Bryan and Starks addressed circumstances where the defendant was not
    accused of violating little-known, complex “administrative regulations” like the
    Act. 
    Id.
     For example, in Bryan the Supreme Court explained that its decision about
    a law that requires firearms dealers to have a license posed little “danger of
    convicting individuals engaged in apparently innocent activity.” 
    524 U.S. at 195
    .
    Indeed, it distinguished Ratzlaf, 
    510 U.S. at 149
    , where it had held that a
    conviction for unlawful structuring of bank deposits requires “the jury . . . to find
    [that the defendant] knew the structuring in which he engaged was unlawful,” 
    id.,
    on the ground that “Ratzlaf involved [a] highly technical statute[] that presented
    the danger of ensnaring” the unwary, Bryan, 
    524 U.S. at 194
     (emphasis added)
    (footnote omitted). And we explained in Starks that the “Anti-Kickback statute . . .
    is not a highly technical . . . regulation that poses a danger of ensnaring persons
    engaged in apparently innocent conduct” and that “kickbacks are . . . malum in se,
    24
    Case: 16-15635      Date Filed: 06/06/2018   Page: 25 of 44
    rather than malum prohibitum.” 157 F.3d at 838 (emphasis added) (italics omitted).
    In contrast, we reasoned in Adames that “the items covered by the [Act] are spelled
    out in administrative regulations and include items not known generally to be
    controlled by the government.” 
    878 F.2d at 1377
     (quoting Davis, 
    583 F.2d at 193
    ).
    Indeed, our analysis was virtually identical to how the Supreme Court in Bryan
    distinguished the “highly technical statues,” 
    524 U.S. at 194
    , at issue in Ratzalf.
    Because Bryan did not “overrid[e]” Adames, we are bound by our precedent about
    the mens rea required by the Act. United States v. Hanna, 
    153 F.3d 1286
    , 1288
    (11th Cir. 1998) (“In this circuit, only the court of appeals sitting en banc, an
    overriding United States Supreme Court decision, or a change in the statutory law
    can overrule a previous panel decision.” (italics omitted)).
    Man contends that the government failed to prove that she conspired
    willfully to violate the Act based on this heightened element of mens rea. She
    asserts that “no evidence [establishes] that the licensing requirements for defense
    articles are widely publicized [or were otherwise known to her].” And she contends
    that, even if the evidence establishes that she knew that direct shipment to China
    was illegal, the evidence fails to establish that she knew that shipment through a
    third-party country was similarly prohibited. We disagree.
    Ample evidence establishes that Man was not merely “aware of the
    generally unlawful nature of her actions,” but that she instead conspired to violate
    25
    Case: 16-15635     Date Filed: 06/06/2018    Page: 26 of 44
    the “known legal duty not to export the [defense articles]” without a license.
    Adames, 
    878 F.2d at 1377
    . For example, she instructed McCauley to ensure that
    “the seller is not from [the Federal Bureau of Investigation].” She later told Liu
    that the “[United States] prohibits sending . . . these types [of engines]” to China,
    and she rejected outright his suggestion of “get[ting] [a] license.” Indeed, Man
    stated that this obstacle was why the buyer “needed [Man and Liu] to . . . do it.”
    And she later referenced the “embargo” on the shipment of goods to China. Man
    also told Liu that Zhang was “a tech spy,” expressed concern about detection by
    the “many federal agents [who are] investigating and arresting many Chinese
    people,” and directed Liu not to “get [her] involved” “[i]f [he] g[o]t caught.” And
    she explained to Liu that China intended to “modify” the drone to disguise that it
    was “stole[n].” These statements entitled the jury to find that Man conspired to
    violate the Act willfully.
    Nor can Man assert that she mistakenly thought that shipment through a
    third-party country was legal even if she knew that direct shipment to China was
    not. To be sure, she suggested to McCauley that she would “give up” if there were
    an “export problem.” And she later told Liu that export through a “third party” “is
    all legal and has no problems.” Despite these statements, other evidence establishes
    that Man knew that federal law squarely prohibited the scheme. Liu told Man that
    “ship[ment] . . . to China is totally illegal.” He also reiterated this warning after
    26
    Case: 16-15635      Date Filed: 06/06/2018    Page: 27 of 44
    Man proposed the third-party option, and Man agreed with Liu that “[i]t [was]
    because of the profit that [they were taking] the risk.” And Man continued to fret
    about criminal exposure even after the conspirators decided to ship via a third-
    party country. For example, she rejected a proposal to deposit money into her bank
    account because “[a] deposit of a large sum is troublesome,” she acknowledged
    that she and Liu were “tak[ing] on the highest risk,” and she reiterated Zhang’s
    concern that “the phone calls in the [United States] are under surveillance.” Liu’s
    warnings, Man’s persistent and calculated attempts to evade detection, and Man’s
    statements about the “embargo” and “license” more than entitled the jury to infer
    that Man conspired willfully to violate the “known legal duty” established by the
    Act. Adames, 
    878 F.2d at 1377
    .
    3.    The Government Did Not Entrap Man.
    Man also contends that she was entrapped as a matter of law. “The
    entrapment defense involves two separate elements: (1) [g]overnment inducement
    of the crime . . . and (2) lack of predisposition on the part of the defendant.”
    Isnadin, 742 F.3d at 1297 (emphasis omitted). On the first element, the defendant
    must satisfy an “initial burden of production” and show “that the [g]overment’s
    conduct created a substantial risk that the offense would be committed by a person
    other than one ready to commit it.” Id. (emphasis omitted) (citation and internal
    quotation marks omitted). After she does so, “the burden shifts to the [g]overnment
    27
    Case: 16-15635     Date Filed: 06/06/2018    Page: 28 of 44
    to prove beyond a reasonable doubt that [she] was predisposed to commit the
    crime.” Id. Predisposition is a question for the jury and “is necessarily a fact-
    intensive, subjective inquiry into a defendant’s state of mind” that considers many
    kinds of evidence about the defendant’s conduct. Id. at 1298. For example, the
    government can point to evidence that the defendant “read[ily] commi[tted] . . . the
    charged crime” or “was given opportunities to back out of [the] transaction[] but
    failed to do so.” Id. (citation and internal quotation marks omitted).
    The district court instructed the jury on entrapment, and the parties contest
    only the second element of whether the government offered sufficient evidence
    that Man was predisposed to commit the crime. Man maintains that she had no
    criminal inclinations and joined the scheme only because of “the [g]overnment’s
    insistence.” She underscores the length of time between her communications with
    McCauley and Liu and that the government did not offer evidence of other,
    “similar conduct on [her] part” outside the conspiracy. This argument fails.
    Sufficient evidence entitled the jury to find that Man was predisposed to
    commit the crime. Man initiated discussions about aircraft engines with McCauley
    before Liu and the government even entered the picture. Liu also repeatedly
    warned Man that her proposals were illegal, but she persisted despite this
    prompting to “back out of [the] transaction[].” Id. Indeed, Man frequently
    responded to legal obstacles by devising ways to avoid detection, such as by
    28
    Case: 16-15635    Date Filed: 06/06/2018   Page: 29 of 44
    shipping the engines through a third-party country and by rejecting the deposit of
    money to her bank account. And her frequent references to how the plan would
    benefit her financial and business interests evidence an eagerness to commit the
    crime.
    To be sure, nothing suggests that Man engaged in similar conduct during the
    18 months between when she asked McCauley about the engines and when
    McCauley put her in touch with Liu, or during the 27 months between Zhang’s
    rejection of Liu’s proposal and Man’s arrest. And Wallace testified that Man never
    approached him about the MQ-9 Reaper drone that his company produces. But that
    Man did not make incessant attempts to procure military items scarcely establishes
    that she lacked independent inclination toward the crime. To the contrary, her
    sporadic, targeted inquiries are fully consistent with the delicate and furtive nature
    of espionage.
    B.       The District Court Did Not Abuse Its Discretion when It Admitted
    Evidence of the Conspirators’ Communications.
    Man complains about three evidentiary rulings. First, she objects on the
    basis of hearsay to the admission of a transcript of a conversation between Liu and
    Zhang. Second, she objects on the same ground to the admission of three emails
    sent to her by an unidentified, unindicted third party. Third, she objects to the
    admission of communications between her and Liu about their efforts to obtain
    technology from Sweden on the basis that this uncharged conduct was inadmissible
    29
    Case: 16-15635   Date Filed: 06/06/2018    Page: 30 of 44
    character evidence and unduly prejudicial. We consider and reject these arguments
    in turn.
    1.     The Transcript of a Conversation Between Liu and Zhang
    Federal Rule of Evidence 802 ordinarily prohibits the admission of hearsay
    statements, but Rule 801(d)(2)(E) creates an exception when a “statement is
    offered against [a defendant]” and “was made by the [defendant’s] coconspirator
    during and in furtherance of the conspiracy.” To avail itself of this exception, “the
    government must prove by a preponderance of the evidence that (1) a conspiracy
    existed, (2) the conspiracy included the declarant and the defendant . . ., and (3) the
    statement was made during the course of and in furtherance of the conspiracy.”
    United States v. Underwood, 
    446 F.3d 1340
    , 1345–46 (11th Cir. 2006).
    We “appl[y] a liberal standard in determining whether a statement was in
    furtherance of a conspiracy.” United States v. Siegelman, 
    640 F.3d 1159
    , 1181
    (11th Cir. 2011). Indeed, “[t]he statement need not be necessary to the conspiracy,
    but must only further the interests of the conspiracy in some way.” 
    Id.
     (citation and
    internal quotation marks omitted). For example, statements that “could have been
    intended to affect future dealings between the parties,” that “provide reassurance,”
    that “serve to maintain trust and cohesiveness,” or that “inform [other conspirators]
    of the current status of the conspiracy” satisfy this standard. 
    Id.
     (citations and
    internal quotation marks omitted).
    30
    Case: 16-15635      Date Filed: 06/06/2018   Page: 31 of 44
    Whether a statement was made in furtherance of a conspiracy is a factual
    issue decided by the district court. United States v. Miles, 
    290 F.3d 1341
    , 1351
    (11th Cir. 2002). The district court “may consider any evidence,” including “the
    alleged hearsay statement and independent outside evidence,” and it “is bound only
    by the privilege rules.” United States v. Byrom, 
    910 F.2d 725
    , 734–35 (11th Cir.
    1990). And it “has discretion to admit the statements [preemptively] subject to
    [later] proof of the[] three requirements during the course of the trial.” United
    States v. Fernandez, 
    797 F.2d 943
    , 945 (11th Cir. 1986).
    Man contends that a transcript of a conversation between Liu and Zhang
    where the men discussed the engines, shipment through a third-party country, and
    Zhang’s earlier communications with Man was inadmissible for two reasons. First,
    she contends that the government failed to prove that she and Zhang were
    conspirators. Second, she argues that insufficient “independent evidence at the
    time of the exhibit’s introduction [established] that Zhang and Man were members
    of the same conspiracy,” especially in the light of her “misunderst[anding] [about]
    the legality of [the scheme].”
    The district court was entitled to admit the transcript. As explained above,
    sufficient evidence suggests a conspiracy between Zhang and Man to violate the
    Act. And the conversation between Zhang and Liu was made during the course of
    and in furtherance of this conspiracy. At the beginning of the conversation, Liu
    31
    Case: 16-15635    Date Filed: 06/06/2018     Page: 32 of 44
    explained to Zhang that he was working “with . . . Man [on] the engines.” Liu then
    informed Zhang what engines he could obtain, told Zhang that “it is not good to
    export directly to China” because “the [United States] would not allow [a sale] to
    China,” and suggested third-party intermediaries. Both Liu and Zhang repeatedly
    referred to Man by name during the conversation and suggested that future
    communications would go through her. And they discussed the prospect of
    obtaining other military goods in addition to the engines. This evidence establishes
    that the conversation occurred during the course of and in furtherance of a
    conspiracy between Man and Zhang. And contrary to Man’s suggestion that the
    district court prematurely admitted this evidence, a district court has discretion to
    “admit [another conspirator’s] statements subject to [later] proof . . . during the
    course of the trial.” 
    Id.
     The totality of the evidence introduced at trial satisfied the
    requirements of the conspirator exception.
    2.      The Emails that an Unidentified Third Party Sent to Man
    As explained above, statements of another conspirator are not hearsay if the
    government proves “that (1) a conspiracy existed, (2) the conspiracy included the
    declarant and the defendant . . ., and (3) the statement was made during the course
    of and in furtherance of the conspiracy.” Underwood, 
    446 F.3d at 1346
    .
    “Statements made by an unindicted coconspirator are admissible so long as the
    government makes the proper showing.” United States v. Montes-Cardenas, 746
    32
    Case: 16-15635     Date Filed: 06/06/2018    Page: 33 of 
    44 F.2d 771
    , 779 (11th Cir. 1984). Indeed, “a defendant may be convicted of
    conspiring with persons whose names are unknown . . . if the indictment asserts
    that such other persons exist . . . and the evidence supports their existence and the
    existence of a conspiracy.” United States v. Rodriguez, 
    765 F.2d 1546
    , 1552 (11th
    Cir. 1985) (citation and internal quotation marks omitted).
    Man objects to the admission of three emails sent to her by the unidentified
    owner of the “hrkj2006” email address between March 2011 and December 2012.
    Although these emails contain repeated references to Liu, Zhang, and the engines,
    Man contends that they are inadmissible hearsay because the government never
    proved that Man was part of a conspiracy, that the owner of the unidentified email
    address was a member of the conspiracy, or that the emails were sent during the
    course of and in furtherance of the conspiracy. But the district court was entitled to
    find otherwise.
    The record establishes that Man was part of a conspiracy to export restricted
    military goods unlawfully, that the owner of the unidentified email address was
    part of the conspiracy, and that the emails were sent during the course of and in
    furtherance of the conspiracy. For example, when Man initially provided Liu with
    Zhang’s email address and cell phone number via email, she also copied the
    “hrkj2006” address. The first disputed email sent to Man from the mystery address
    was part of an email thread that included an email from Man with the subject line
    33
    Case: 16-15635      Date Filed: 06/06/2018    Page: 34 of 44
    “Forward: Mr. Zhang’s Order” and listed the model numbers of the engines and
    aircraft that were the objects of the conspiracy. It also referenced earlier
    communications between Liu and Zhang, the legal difficulties posed by export to
    China, and the plan to “obtain the technical information.” The second email sent
    from the unknown address to Man again listed several engines, and, two days later,
    Man asked McCauley about these engines. And the third disputed email referenced
    Zhang and directed Man to locate the engines. These emails evidence that Man
    was part of a conspiracy to violate the Act, that the owner of the address also was
    part of the conspiracy, and that the emails were sent during the course of and in
    furtherance of the conspiracy.
    3.     Communications Between Man and Liu About the Swedish Decoy Aircraft
    Federal Rule of Evidence 404(b) may foreclose the admission of uncharged
    crimes and other bad acts, but this rule does not apply to evidence that is
    “intrinsic” to “the charged offenses.” United States v. Ford, 
    784 F.3d 1386
    , 1394
    (11th Cir. 2015). Evidence is intrinsic if it “arose out of the same transaction or
    series of transactions as the charged offense,” is “necessary to complete the story
    of the crime,” or is “inextricably intertwined with the evidence regarding the
    charged offense.” United States v. Ramsdale, 
    61 F.3d 825
    , 829 (11th Cir. 1995)
    (citation and internal quotation marks omitted). The district court may exclude
    such evidence “if its probative value is substantially outweighed by a danger of . . .
    34
    Case: 16-15635     Date Filed: 06/06/2018   Page: 35 of 44
    unfair prejudice,” Fed. R. Evid. 403, but exclusion is “an extraordinary remedy that
    must be used sparingly,” United States v. U.S. Infrastructure, Inc., 
    576 F.3d 1195
    ,
    1211 (11th Cir. 2009).
    Man contends that the transcript of a conversation and an email where she
    asked Liu about a Swedish decoy aircraft were inadmissible because this evidence
    was extrinsic, irrelevant, and prejudicial. She underscores that these
    communications were not made in furtherance of a conspiracy because her attempt
    to obtain the decoy aircraft was not charged in the indictment. And she concludes
    that this evidence was “pure propensity evidence” that violated Rule 404(b) and
    imposed substantial prejudice in violation of Rule 403. We disagree.
    The evidence about Man’s inquiries into the Swedish aircraft was intrinsic
    and admissible. The conversation and phone call “arose out of the same . . . series
    of transactions as the charged offense” and were “inextricably intertwined with the
    evidence regarding the charged offense,” Ramsdale, 
    61 F.3d at 829
     (citation and
    internal quotation marks omitted), because they were two in a series of
    communications between Man and Liu about what military goods Liu could
    provide to the conspirators. Indeed, Man made frequent references to Zhang in the
    conversation, and Man sent the email as a follow-up to an earlier conversation with
    Liu that the government had admitted into evidence without objection. This
    evidence of ongoing discussions between Man and Liu also underscored that Man
    35
    Case: 16-15635     Date Filed: 06/06/2018   Page: 36 of 44
    was the vital link between Liu and Zhang and offered the jury insight into Man and
    Zhang’s relationship. Indeed, Man’s statement during the conversation that her
    company might “sponsor” Zhang for entry to the United States showed that she
    had a significant role in the scheme.
    The prejudicial effect of this evidence also did not “substantially
    outweigh[]” its probative value. Fed. R. Evid. 403. Evidence of an ongoing and
    active relationship between Man, Zhang, and Liu was highly probative of Man’s
    active role in a conspiracy to violate the Act. Indeed, Man’s persistent
    communications with Liu rebutted her suggestion that she was an unwilling
    participant entrapped by the government. The district court also instructed the jury
    that Man was not “accused of conspiring to export [the Swedish decoy]” and that
    the jury “should not speculate whether such an act would have been legal or
    illegal.” And “we must presume that [the] jur[y] follow[ed] th[is] instruction[].”
    United States v. Zitron, 
    810 F.3d 1253
    , 1258 (11th Cir. 2016) (quoting Johnson v.
    Breeden, 
    280 F.3d 1308
    , 1319 (11th Cir. 2002)). In short, the district court did not
    abuse its discretion when it refused to invoke the “extraordinary remedy” of Rule
    403. U.S. Infrastructure, 
    576 F.3d at 1211
    .
    C. Man’s Sentence is Procedurally and Substantively Reasonable.
    Man makes two arguments about her sentence. She contends that her
    sentence is procedurally unreasonable because the district court failed to decrease
    36
    Case: 16-15635      Date Filed: 06/06/2018    Page: 37 of 44
    her offense level for her “minimal participa[tion]” in the conspiracy. See U.S.S.G.
    § 3B1.2(a). And she contends that her sentence is substantively unreasonable
    because the district court erroneously considered her “national origin.” See
    U.S.S.G. § 5H1.10. Neither argument is persuasive.
    1.     Procedural Reasonableness
    The Sentencing Guidelines direct a district court to decrease a defendant’s
    offense level by four levels “[i]f the defendant was a minimal participant in [the]
    criminal activity.” U.S.S.G. § 3B1.2(a). “The defendant bears the burden of
    establishing [this adjustment] by a preponderance of the evidence.” Cruickshank,
    837 F.3d at 1192. “In determining whether [the] adjustment applies, the district
    court should consider, first, the defendant’s role in the relevant conduct for which
    he has been held accountable at sentencing, and, second, his role as compared to
    that of other participants in his relevant conduct.” United States v. Wright, 
    862 F.3d 1265
    , 1277–78 (11th Cir. 2017) (citation and internal quotation marks
    omitted). The district court must consider “all of the facts probative of [her] role in
    her relevant conduct,” United States v. Rodriguez De Varon, 
    175 F.3d 930
    , 943
    (11th Cir. 1999), and evaluate “the totality of the circumstances and . . . the facts of
    [each] particular case,” U.S.S.G. § 3B1.2 cmt. n.3(C). To assist courts with this
    task, the Guidelines provide a “non-exhaustive list of factors,” such as “the degree
    to which the defendant understood the scope and structure of the criminal activity,”
    37
    Case: 16-15635   Date Filed: 06/06/2018   Page: 38 of 44
    “the degree to which the defendant participated in planning or organizing the
    criminal activity,” “the degree to which the defendant exercised . . . or influenced
    the exercise of decision-making authority,” the “nature and extent of the
    defendant’s participation,” and “the degree to which the defendant stood to
    benefit.” Id.
    Man contends that she was entitled to a downward adjustment for her
    minimal role. She underscores that she reported to Zhang, that Zhang had final
    authority to negotiate a deal with Liu, that Zhang was the “principal target” of the
    investigation, and that she was just one actor in a larger criminal conspiracy to
    steal any and all American technology. And she suggests that she could not have
    played an important role in the conspiracy because her “mental health status was
    questionable.” We disagree.
    The district court did not clearly err when it took a “permissible view[]” of
    the evidence to the contrary. Rodriguez De Varon, 
    175 F.3d at 945
     (citation and
    internal quotation marks omitted). Man’s own “relevant conduct,” 
    id.,
     establishes
    that she played “an important or essential role” in the charged conspiracy, 
    id. at 943
    . For example, she put Liu in touch with Zhang, discussed prices and terms
    with Liu, and even explained that she was a necessary figure because she was “in
    the [United States]” and Zhang was “physically in China.” Similarly, the “nature
    38
    Case: 16-15635     Date Filed: 06/06/2018    Page: 39 of 44
    and extent of [her] participation” was substantial because she was the sole
    domestic intermediary between Zhang and Liu. U.S.S.G. § 3B1.2 cmt. n.3(C).
    The record also establishes that Man played a meaningful role in “planning
    or organizing” the crime. Id. She made the initial connections with McCauley and
    Liu, put Liu in touch with Zhang, and discussed routing the contraband through a
    third-party country to evade detection. And she assumed an active role when she
    suggested that she might sponsor Zhang for entry into the United States.
    Man also “understood the scope and structure of the criminal activity.” Id.
    She frequently stated that the scheme was illegal and risky and even proposed
    evading detection by shipping the engines through a third-party country. Her
    description of Zhang as “a tech spy” who had “made similar transaction[s] with
    Russia” also underscores her knowledge about the scope of her criminal behavior.
    And Man “stood to benefit” from the enterprise. Id. For example, she
    repeatedly discussed her “commission,” with Liu, demanded a “profit” of “over . . .
    10 percent,” and agreed with Liu’s statement that “[it] [was] because of the profit
    that [they were] tak[ing] the risk.” She also suggested that her participation in the
    deal would allow her company to do business in China.
    Finally, Man’s suggestion that her mental health status entitles her to a
    minimal-role adjustment under section 3B1.2 is meritless. Mental capacity is
    covered by a different section of the Guidelines, § 5K2.13, the district court denied
    39
    Case: 16-15635    Date Filed: 06/06/2018   Page: 40 of 44
    Man a downward departure under that section, and Man abandoned her argument
    for a downward departure when she failed to invoke that section on appeal. See
    Access Now, Inc. v. Sw. Airlines Co., 
    385 F.3d 1324
    , 1330 (11th Cir. 2004)
    (“Under our caselaw, a party seeking to raise a claim or issue on appeal must
    plainly and prominently so indicate.” (citation and internal quotation marks
    omitted)). And even if we could review this abandoned argument, the district court
    was entitled to reject Man’s contention based on its finding that “Man asked
    specific questions, made repeated requests for assurances, [and] had clear follow-
    up[s]” during “[t]he period of time that [she] was involved in the [conspiracy].”
    Indeed, Man’s persistent, deliberate, and sophisticated communications with
    McCauley, Lin, and Zhang over a long period of time and her frequent expressions
    of concern about detection by law enforcement show a heightened awareness of
    and control over her conduct. She cannot now disclaim responsibility for her
    actions.
    2.     Substantive Reasonableness
    “[A] sentence may be substantively unreasonable when the district court . . .
    bases the sentence on [an] impermissible factor[],” United States v. Pugh, 
    515 F.3d 1179
    , 1191–92 (11th Cir. 2008), such as a defendant’s “[n]ational [o]rigin” or
    “[r]eligion,” U.S.S.G. § 5H1.10. But we have clarified that mere references to a
    forbidden factor are permissible when the district court imposes the sentence
    40
    Case: 16-15635    Date Filed: 06/06/2018    Page: 41 of 44
    because of the behaviors and motivations prompted by that factor and not by the
    underlying factor itself. For example, in United States v. Clay, we explained that a
    “district court did not consider [a defendant’s] religious belief[s]” when it “credited
    testimony . . . about changes in [the defendant’s] life that followed his religious
    conversion.” 
    483 F.3d 739
    , 745 (11th Cir. 2007) (emphasis added). We have also
    explained that the district court may consider the gravity of behaviors that have an
    “impact on national security.” United States v. Valnor, 
    451 F.3d 744
    , 751 (11th
    Cir. 2006).
    Man contends for the first time on appeal that the district court erroneously
    relied on her national origin. She points to its statements at the sentencing hearing
    that Man acted out of a “commitment to help the Republic of China” and that she
    was “faithful to [her] native country.” And she renews her complaint about the
    assertion of the government its sentencing memorandum that Man put “nationalism
    before [her family] in her priorities.” We are unpersuaded.
    The district court was entitled to reference Man’s allegiance to China. To
    begin, the discussion of Man’s loyalty has nothing to do with her identity, for an
    American citizen can be loyal to a foreign country for a variety of reasons that
    have nothing to do with national origin or ethnicity. See, e.g., United States v.
    Rosenberg, 
    195 F.2d 583
    , 604 (2d Cir. 1952) (explaining that the defendants
    contended that, “at the most, out of idealistic motives, they gave secret information
    41
    Case: 16-15635     Date Filed: 06/06/2018    Page: 42 of 44
    to Soviet Russia” (emphasis added)). Indeed, the district court “reject[ed Man’s
    argument] that . . . [her] national origin [was] an issue” and explained that her
    “actions,” and not her “national origin,” were “the relevant factor.” It also
    underscored that her conduct had significant “potential [to] harm[] . . . national
    security” and that “[t]he clear intent of th[e] conspiracy was to enable [China]” to
    steal military technology. This examination of the consequences and motivations
    of Man’s behavior, particularly its implications for “national security,” Valnor, 
    451 F.3d at 751
    , was legitimate, see Clay, 
    483 F.3d at 745
    .
    D.     No Plain Error Occurred when the Government Failed To Provide Man
    with an Email Sent by Liu to Zhang.
    Under Brady, the government must not “suppress[] . . . evidence favorable to
    [the] accused.” United States v. Esquenazi, 
    752 F.3d 912
    , 933 (11th Cir. 2014)
    (quoting Brady, 
    373 U.S. at 87
    ). To establish a violation of this duty to disclose
    exculpatory evidence, the defendant must prove that “the government possessed
    favorable evidence,” that she did “not possess the evidence and could not [have]
    obtain[ed] the evidence with any reasonable diligence,” that the government
    “suppressed the favorable evidence,” and that the evidence creates a “reasonable
    probability” of a different outcome. United States v. Vallejo, 
    297 F.3d 1154
    , 1164
    (11th Cir. 2002).
    Man contends that the government failed to provide her with an email that
    Liu sent to Zhang in October 2012. The record does not establish the contents of
    42
    Case: 16-15635     Date Filed: 06/06/2018   Page: 43 of 44
    the email, likely because Man failed to raise the issue to the district court and
    permit it an opportunity to hold an evidentiary hearing. Indeed, the only reference
    to the existence of this email is found in a transcript of a phone conversation
    between Liu and Man that the government introduced at trial. In this conversation,
    Liu mentions that he “sent out an e-mail” to Man’s “friend in China” but “forgot to
    [copy her].” According to Man, this email is material because it “could have been
    used to impeach the statements of . . . Liu” at trial.
    No plain error occurred. Man knew about the email because Liu mentioned
    it to her during their conversation, yet she failed to exercise “reasonable diligence”
    in procuring it before trial. 
    Id.
     Indeed, she even told Liu in the same conversation
    she had “talked to [Zhang] over the phone” about the email, further underscoring
    her awareness. She also fails to offer any evidence or articulate any inference to
    establish a “reasonable probability” that the email would have changed the verdict.
    
    Id.
     On the contrary, the email almost certainly would have helped the government
    establish a conspiracy by reinforcing the connection between Man and Zhang. For
    example, during his post-email conversation with Man, Liu suggested that he
    should have copied her on the email. And Man suggested that Zhang had informed
    her that the email was about the engines. This evidence is entirely consistent with a
    conspiracy and would have been of little use to Man.

    IV. CONCLUSION
    We AFFIRM Man’s judgment of conviction and sentence.
    44
