  • UNITED STATES DISTRICT COURT
    FOR THE DISTRICT OF COLUMBIA
    UNITED STATES,
    No. 06-cr-89 (RDM)
    NIZAR TRABELSI,
    Defendant.
    MEMORANDUM OPINION AND ORDER
    In April 2006, a grand jury returned an indictment against Defendant Nizar Trabelsi
    containing four counts, two of which the government later dismissed. Dkt. 3. The two
    remaining counts allege that Trabelsi conspired to kill U.S. nationals outside the United States, in
    violation of 
    18 U.S.C. §§ 2332
    (b)(2) and 1111(a), and conspired and attempted to use weapons
    of mass destruction, in violation of 18 U.S.C. §§ 2332a and 2.! Dkt. 6 at 1-9. Among other
    overt acts, the indictment alleges that Trabelsi “met with Osama bin Laden” in the Spring of
    2001 near Kandahar, Afghanistan “and offered to carry out a suicide bomb attack against United
    States interests,” Dkt. 6 at 6; that he “obtained money from an al Qaeda associate for use in
    carrying out his mission to bomb a United States target,” id. at 7; that in July and August 2001,
    Trabelsi “bought quantities of chemicals” in Belgium “to be used in manufacturing a 1,000-
    kilogram bomb,” id. at 8; and that he “traveled at night with conspirators to scout the Kleine-
    ' The indictment also charged Trabelsi with conspiring to provide material support and resources
    to a designated foreign terrorist organization, in violation of 18 U.S.C. § 2339B, and with
    providing material support and resources to a foreign terrorist organization, in violation of 18
    U.S.C. §§ 2339B and 2. Dkt. 3 at 9-10. On the government’s motion and with the consent of
    Trabelsi, these two counts were dismissed with prejudice in 2019. See Dkt. 231; Min. Order
    (June 10, 2019).
    Brogel Air Force Base—a facility used by the United States and the United States Department of
    the Air Force, and at which United States nationals were present—as a target for a suicide bomb
    attack,” id. In 2013, after serving a ten-year sentence in Belgium for, among other things,
    attempting to destroy the Kleine-Brogel Air Force Base, see Dkt. 367-3 at 24, Trabelsi was
    extradited to the United States on the instant charges. Trial commenced with jury selection on
    May 8, 2023.
    Before trial began, the Court authorized the government to take a videotaped deposition
    of a foreign-national witness living in France “in order to preserve [her] testimony for trial.”
    Fed. R. Crim. P. 15(a)(1); see Dkt. 578. The government now moves to admit that video-taped
    deposition at trial, Dkt. 588, and Trabelsi has cross-moved to strike that testimony from the
    record, Dkt. 590.” Trabelsi argues that admitting this testimony would violate his Sixth
    Amendment right to “be confronted with the witnesses against him,” U.S. Const. amend. VI,
    because, among other things, the deposition occurred via videoconference and because he was
    provided, in his view, an insufficient opportunity to cross-examine the witness during the time
    allotted for the deposition. For the reasons that follow, the Court will GRANT the government’s
    motion, Dkt. 588, and will DENY the defendant’s cross-motion, Dkt. 590.
    > Although Trabelsi’s motion is styled as a motion to strike, the deposition has not yet been
    admitted into the record. The Court will, accordingly, treat this filing as a motion to preclude
    admission of the deposition at trial or, in the alternative, as an opposition to the government’s
    motion.
    I. BACKGROUND
    A. Authorization to Take the Deposition
    In January 2023, the government moved to take the deposition of Ms. Amal*—a foreign-
    national witness living in France—pursuant to Federal Rule of Criminal Procedure 15. See Dkt.
    501; Dkt. 505. That rule allows for “a prospective witness [to] be deposed in order to preserve
    testimony for trial” if merited by “exceptional circumstances and in the interest of justice.” Fed.
    R. Crim. P. 15(a)(1). In support of its Rule 15 motion, the government represented that Ms.
    Amal was in a relationship with Trabelsi between 2000 and 2001 and could, as a result, provide
    “unique testimony about Trabelsi’s criminal conduct, including his travel to Afghanistan where
    he met Osama bin Laden, enlisted to become a martyr, and received training to commit an
    attack.” Dkt. 505 at 6. The government further explained that a deposition was necessary to
    preserve this material testimony because the witness had “definitively stated [to government
    counsel] that she [was] not willing to travel to the United States to testify,” Dkt. 544 at 1,
    notwithstanding the government’s “long, diplomatic face-to-face discussions with [her] about the
    importance of her testimony,” Dkt. 570-1 at 2. The government also reported that Ms. Amal had
    reluctantly agreed to travel to Paris for a two-day video deposition, but—due to severe ongoing
    medical concerns with her children and the fact that she had to travel away from her family to
    Paris for the deposition—had “agreed to testify . . . only for two days.” Jd. at 2-3 (emphasis
    omitted).
    3 With the parties’ consent, the Court has ordered that the witness shall be referred to as “Ms.
    Amal” and that her family name not be referenced on the public record or in public filings. The
    Court struck this balance to protect the safety of the witness and her family while avoiding any
    prejudice to the defendant in proceedings before the jury, which will know the witness only by
    this name.
    Trabelsi, who was pro se at the time but was assisted by standby counsel in briefing the
    Rule 15 motion, opposed the pretrial deposition. He contested the government’s representations
    that Ms. Amal was unavailable for trial and argued, most centrally, that a two-day deposition
    would be “insufficient” to cross-examine this “key witness.” Dkt. 506 at 5—6; see also Apr. 19,
    2023 Hrg. Tr. (Rough at 15—16).
    After briefing and argument on the Rule 15 motion, this Court authorized the government
    to proceed with its proposed two-day deposition. Dkt. 578. The Court concluded that
    “exceptional circumstances” merited a Rule 15 deposition because the government had
    established both “the materiality of [Ms. Amal’s] testimony” and “the unavailability of the
    witness to testify at trial.” Dkt. 578 at 3 (quoting United States v. Cooper, 
    947 F. Supp. 2d 108
    ,
    112 (D.D.C. 2013)); see also United States v. Johnpoll, 
    739 F.2d 702
    , 709 (2d Cir. 1984) (“It is
    well-settled that the “exceptional circumstances’ required to justify the deposition of a
    prospective witness are present if that witness’ testimony is material to the case and if that
    witness is unavailable to appear at trial.”). As to materiality, the Court noted that Ms. Amal—
    unlike the other witnesses in the case—was apparently prepared to testify “firsthand” about
    “loading ammunition belts for the defendant in Afghanistan;” about witnessing “the defendant’s
    radicalization and the path he traveled . . . in his effort to become a martyr;” and about Trabelsi’s
    “relationship with . .. Djamel Beghal and Jerome Courtailler, who have both been convicted of
    terrorism offenses.” Dkt. 578 at 4 (quoting Dkt. 505 at 6). There was a substantial likelihood,
    moreover, that the witness would not testify at trial: she is not only beyond the Court’s subpoena
    power, but she had also, by then, “definitively stated that she [was] not willing to travel to the
    United States to testify.” Jd. at 5-6 (quoting Dkt. 544 at 1). The Court also concluded that “it
    [was] very unlikely that Ms. Amal w[ould] have a change of heart and. . . decide to come to the
    United States to testify” at trial in light of the government’s representations that she “is terrified
    of the defendant” and that two of her minor children “were struck by a car in March and [were]
    seriously injured.” Jd. at 6 (internal quotation marks omitted). The Court noted, on this point,
    that Ms. Amal’s EE daughter “was required to remain in bed, immobile” as a result of
    that accident, and that, as of mid-April, her daughter “continue[d] to receive medical care,”
    Rn. {2 (quoting Dkt. 570-1 at 2).
    The Court further concluded that Fed. R. Crim. P. 15(c)(3) allowed the government to
    “tak[e]” this deposition “outside the United States . . . without the defendant’s presence.” Jd. at
    8. Critically, the Court explained, Trabelsi could not be “present [in France]” for the deposition
    because his “secure transportation and continuing custody c[ould not] be assured at the witness’s
    location.” Dkt. 578 at 9 (quoting Fed. R. Crim. P. 15(c)(3)(D){E)). In particular, Stephen
    Panepinto, Chief of the Office of International Operations in the United States Marshals Service,
    attested that “[t]he United States Marshals Service does not have authority to maintain custody of
    a prisoner in a foreign country,” 
    id.
     (quoting Dkt. 526-1 at 1 (Panepinto Decl. { 3)), and that it
    “would be impossible for the U.S. Marshals to enforce” the Special Administrative Measures
    (SAMs) to which Trabelsi is subject “while . . . Trabelsi is within a European country,” 
    id.
    (quoting Dkt. 526-1 at 2 (Panepinto Decl. ¥ 7)).
    Finally, the Court addressed Trabelsi’s Confrontation Clause concern as to the limited
    length of the deposition. The Court explained that, although “the Confrontation Clause
    guarantees an opportunity for effective cross-examination,” it does not guarantee “cross-
    examination that is effective in whatever way, and to whatever extent, the defense might wish.”
    Delaware v. Fensterer, 
    474 U.S. 15
    , 20 (1985) (per curiam). And “at the outset and before the
    deposition ha[d] even begun,” the Court could not conclude that “a two-day deposition w[ould]
    provide insufficient opportunity for Trabelsi to [effectively] cross-examine Ms. Amal—
    especially in light of the government’s reported efforts to limit the length of its direct
    examination.” Dkt. 578 at 13 (emphasis added). Drawing on its observation that “many (indeed,
    most) of [the] questions” Trabelsi had asked of two prior witnesses who appeared at a
    suppression hearing “were argumentative, repetitive, or irrelevant,” the Court also warned
    Trabelsi that he should “limit his examination to proper and relevant questions within the scope
    of the government’s direct examination of its witness” and, as it had on several prior occasions,
    encouraged him “to focus his deposition preparation to ensure that he ha[d] time to ask the
    witness those questions that are necessary to his defense.” Dkt. 578 at 13-14; see also Apr. 25,
    2023 p.m. Hrg. Tr. (Rough at 4—5) (“[I]t’s . . . very important that [Trabelsi] be as efficient as he
    can and that he ask questions that are relevant[,] that are questions and not testimony[,] that are
    short and to the point[,] and [that] relate to the direct testimony that the government is
    eliciting, .. . includfing,] if appropriate[,] impeachment of that testimony.”). He could not, the
    Court cautioned, “deprive the government of a witness by engaging in significant, unnecessary
    delay” during the deposition. Dkt. 578 at 14.4
    After observing Trabelsi’s over-long and unfocused cross-examination of one of the
    witnesses at the suppression hearing, moreover, the Court set forth a general rule of thumb to
    guide the examination of future witnesses. “[R]ecognizing that Mr. Trabelsi is proceeding pro
    “ These warnings echoed the Court’s cautions during the Faretta Hearing at which Trabelsi
    elected—over the advice of the Court—to represent himself. At that hearing, the Court warned
    Trabelsi that he would be “disadvantage[d]” by his self-representation because, among other
    things, the “rules [of evidence and criminal procedure]” are complicated” and that the Court
    “c[ould] [not] help [Trabelsi]” or rule in his favor “just because [he was] representing [him]self.”
    July 8, 2022 Hrg. Tr. (Rough at 20-21). The Court further advised Trabelsi that he would “be
    better off with a trained lawyer.” Jd. at 25.). Trabelsi acknowledged that he would not “benefit”
    from “special treatment,” 
    id. at 20
    , and that he was aware of the risks of self-representation, 
    id. at 22
    , but he nevertheless insisted on representing himself pro se.
    se, and recognizing that the issues in the case are of enormous importance to him”—as well as
    the need “reasonably to manage the case”—the Court proposed “allow[ing] Mr. Trabelsi ... as a
    rule of thumb to have twice the time the government takes with respect to [its] direct”
    examination to conduct his cross-examinations. Apr. 19, 2023 Hrg. Tr. (Rough at 4-5). To
    merit “any time beyond [that]” at the deposition or otherwise, the Court explained, Trabelsi
    “would have to make a showing of specific need and would have to explain to [the Court] why
    he needs more than two times the amount of time the government is using for its direct.” Jd. at 4.
    In a further effort to promote efficiency and fairness, the Court requested that Magistrate Judge
    Upadhyaya preside over the deposition, and she graciously agreed to do so. See Apr. 18, 2023
    Hrg. Tr. (Rough at 235) (explaining that Judge Upadhyaya would “make sure things are run
    efficiently” and that “there’s not any harassment of the witness”).
    Cognizant, however, of Trabelsi’s concern about the length of the deposition, the parties
    and the Court planned to maximize the witness’s availability during the two-day window on
    April 26, 2023 and April 27, 2023. The deposition was scheduled to begin each day at 9:00 a.m.
    and to end “at or around 6:00 p.m. EST” (i.e., midnight in Paris), Dkt. 579 at 1; Judge
    Upadhyaya warned that “[b]oth sides should be prepared to conclude their questioning of Ms.
    Amal in the time allotted, by 6 p.m. EST on Thursday, April 27, 2023,” id. at 3. And, although
    Trabelsi and government counsel would be given the opportunity to preserve objections for the
    record, the Court urged the parties, in the interest of saving time, to state their objections
    concisely (e.g., “object [as to] . .. form” or “[lack of] foundation”) without further explanation or
    argument during the deposition itself. Apr. 26, 2023 a.m. Dep. (Tr. at 8). According to the
    > The Court subsequently held a lengthy, multi-part hearing to rule on the parties’ objections and
    provided both the government and the defense with ample opportunity to expand upon any
    government, moreover, it substantially curtailed the scope if its direct examination of Ms. Amal,
    limiting its questions “to the bare minimum,” to ensure that Trabelsi would have sufficient time
    for cross-examination, Apr. 19, 2023 a.m. Hrg. Tr. (Rough at 4). “We want to create a record,”
    the government explained, “so that the Court can say the government got their questions done in
    two to two and a half hours, and the defendant had all that other time to get his cross-
    examination in.” Id.; see also Apr. 18, 2023 Hrg. Tr. (Rough at 230) (“[W]e’re carefully culling
    ... all of our questions to reduce [Jour direct to the bare minimum.”). And, again, the Court
    encouraged Trabelsi to “sit down with [his standby counsel] in advance and [to prepare] an
    outline” in the interest of “mak[ing] the best use of [his] time” on cross-examination. Apr. 18,
    2023 Hrg. Tr. (Rough at 233). The Court further invited standby counsel to conduct the
    deposition in Trabelsi’s stead. Apr. 24, 2023 Hrg. Tr. (Rough at 102). It was apparent to the
    Court, however, that one of the reasons why Trabelsi decided to exercise his Faretta rights and
    to proceed pro se was precisely so that he could personally question this witness.
    B. The Rule 15 Deposition
    The deposition began on April 26, 2023 at approximately 9:50 a.m.—a delay that was
    attributable to minor technological difficulties with the videoconferencing software. Apr. 26,
    2023 a.m. Dep. Tr. (Rough at 8). Trabelsi, one of his standby counsel, and government counsel
    were physically present in Courtroom 5 of E. Barrett Prettyman Courthouse in Washington, D.C.
    The witness, Trabelsi’s second standby counsel, two representatives of the U.S. government, and
    several representatives of the French government were physically present at the deposition in
    Paris. Ms. Amal testified via the video-conferencing technology Jabber; that technology allowed
    objections made during the deposition, no matter how briefly. See Min. Entry (June 1, 2023);
    Min. Entry (June 2, 2023); Min. Entry (June 5, 2023).
    her to see Trabelsi in the Courtroom and for Trabelsi simultaneously to observe her during her
    testimony. Trabelsi represented himself at the deposition. His questions were translated from
    French to English for the record, and then back to French by the remote interpreters for Ms.
    Amal; the witness’s French answers, in turn, were translated back into English for the record and
    back to French for Trabelsi. Dkt. 579 at 4. At the outset, Ms. Amal acknowledged her
    understanding that “the oath . . . require[d] [her] to tell the complete truth” and that, if she did not
    do so, she would “be subject to certain sanctions, including sanction of perjury.” Apr. 26, 2023
    a.m. Dep. (Tr. at 11).
    l. Direct Examination
    On direct examination, Ms. Amal testified that she entered a romantic relationship with
    Trabelsi in Dusseldorf, Germany around 1998, when she was about 19 or 20 years old. Id. at 13—
    14. Ms. Amal explained that “[a]t some point in [their] relationship,” before the two resided
    together, Trabelsi told her that “he had gone to see an imam,” and he “presented to [her] a
    paper .. . [which] said that [they] were married.” Jd. at 14. She further testified that, after
    Trabelsi announced that they were married, she personally observed, overheard, or was informed
    by Trabelsi about various plans and events relevant to the government’s allegations. According
    to that testimony:
    e She observed, on several occasions, Trabelsi watching videos with “violent imagery”
    with his “Muslim brothers,” including videos of “Israelis eating the intestines of
    Palestinian or Chechnyan women,” of “people . . . learning to shoot guns and
    weapons,” id. at 23-24, and of explosions of a building in Nairobi, Kenya, Apr. 26,
    2023 p.m. Dep. (Tr. at 9). Ms. Amal also testified that “Mr. Trabelsi was happy
    while watching these videos, and at the same time . . . was shouting: ‘Allahu Akbar.
    Allahu Akbar.’” Id. at 10.
    e In 2000, she overheard conversations in her apartment between Trabelsi, Djamel
    Beghal, Mouloud el Mourabit, Salman, and Jerome Courtailler, about traveling to
    Afghanistan. Apr. 26, 2023 a.m. Dep. (Tr. at 26-28).
    In September 2000, she spent “several weeks in Paris,” staying at Djamel Beghal’s
    house, “to prepare for the trip to Afghanistan.” Jd. at 32.
    She traveled with Trabelsi to Peshawar, Pakistan, using what she understood to be a
    fraudulent visa created by Djamel Beghal, where she stayed for several weeks alone
    while Trabelsi traveled to Afghanistan for “explosives training.” Jd. at 29-40.
    She relocated to Jalalabad, Afghanistan, from Peshawar, where she lived in a house
    purchased by Trabelsi, Apr. 26, 2023 p.m. Dep. (Tr. at 4-5), and where Trabelsi left
    her for days at a time for “explosives training” sponsored by Al Qaeda, id. at 6-7.
    She learned, from Trabelsi and “other brothers,” how to fire a Kalashnikov rifle while
    in Jalalabad. Id.
    She visited Osama Bin Laden’s house for the wedding of Bin Laden’s son. /d. at 11.
    She heard Trabelsi say, after visiting Osama Bin Laden, that Bin Laden “was his
    father, his idol and his benchmark.” Td.
    She learned from Trabelsi that he “took part in blasting . . . statu[es]” of Buddha; that
    he “was very happy about it;” and that “he brought back a bag full of earth from the
    statu[es].” Jd. at 12.
    She observed Trabelsi coming back from meeting Osama Bin Laden with “a note on
    him saying that he would . . . become a martyr” and learned from Trabelsi that he
    “was going to go to Europe and stage an attack there,” id. at 13, “that he would have
    the U.S. embassy in Paris be the target of this attack by explosion,” id. at 14, and that
    she would, after the attack “marry someone else,” id. at 16.
    In Trabelsi’s home, she observed “weapons and chemical products.” Jd. at 31.
    According to Ms. Amal, she was arrested and questioned by French law enforcement
    officers in September 2001, after Trabelsi’s arrest and while she was pregnant. Jd. at 32-33.
    She testified that she “did not tell the truth” when she was first arrested “because [she] was very
    scared.” Jd. at 33. She explained, however, that, “later, [she] did tell the truth, and the whole
    truth,” id.; that her lies were “an error of youth,” id. at 35; and that she “decide[d] to tell the
    truth” later “so that [she] would be able to save everyone,” id. All told, the government
    represents—and defense counsel does not dispute—that the direct examination of Ms. Amal
    lasted less than 3 hours. Dkt. 588 at 2.
    10
    2. Cross-Examination
    Trabelsi began his cross-examination of Ms. Amal around 3:00 p.m. on April 26, 2023.
    See id. at 37 (instruction from Judge Upadhyaya that Trabelsi had “three more hours today”).
    Some of the delay up to this point (about 50 minutes) was occasioned by three bathroom breaks
    that Trabelsi requested for what appears to have been a legitimate medical reason. At the outset,
    Trabelsi expressed concern about whether “the time [would] be enough” and articulated his fear
    that “ask[ing] [the witness] question[s] under pressure” would mean that he could not “work as
    [he] wish[ed].” Jd. at 36. Acknowledging his concern, Judge Upadhyaya once again warned
    Trabelsi to “ask the important questions,” to “use [his] time wisely,” and not “to waste time.” Id.
    at 37.
    Trabelsi promptly ignored Judge Upadhyaya’s instructions. He began his cross-
    examination with a series of personal questions to the witness: “Are you doing okay?” “Is my
    son doing well?” “And your children, are they well?” Jd. at 44. Again, a few minutes later, he
    asked: “Are you afraid of some harm that could happen to you and the children?”—a question
    the government objected to as “designed to intimidate the witness.” Jd. at 48. After Trabelsi
    asked, “What can I do for your children to help you?” id. at 49, Judge Upadhyaya reminded
    Trabelsi that “these are not questions that are relevant, Mr. Trabelsi, about her children,” and she
    urged him to focus on “questions about the case.” Jd.
    Trabelsi at least briefly heeded Judge Upadhyaya’s instruction, turning to questions about
    the veracity of Ms. Amal’s initial statements to the French authorities after her arrest in
    September 2001 and her purported motivations to lie to the French police when she was first
    questioned. Jd. at 52-54. But he quickly turned back to questions that were irrelevant (or of
    11
    marginal relevance), repetitive of undisputed matters already in the record, or merely
    argumentative. He asked, for instance:
    Q. [M]y question is in general, do you think that any woman who is pregnant
    and who is having problems, any kind of problems, has the right to swear to
    God and then to lie to other people?
    A. It’s true that I was pregnant, but I really don’t understand your question. It
    really is out of bounds.
    Q. Is it because you are pregnant that you think you have the right to swear to
    God and then to lie to hurt other people to protect yourself?
    [A.] First of all, those questions don’t interest me. And second of all, yes, I was
    pregnant and of course I thought of myself, and then I decided to tell the
    truth.
    Id. at 55. Again, a few minutes later, Trabelsi asked: “Mrs. Amal, were you a married and happy
    woman or a married and very unhappy woman?” Jd. at 60. Judge Upadhyaya again reminded
    Trabelsi “to focus on questions about the case.” Jd.
    Notwithstanding the repeated warnings to use his time efficiently, Trabelsi spent much of
    his time on cross-examination testifying at length about his case. For example:
    Q. Mrs. Amal, do you remember coming to see me in jail with my son when he
    was four months old, and they refused to let you in because you didn’t have
    a visit authorization; and so you were very upset, and you called my lawyer,
    and my lawyer called the judge to ask him to authorize the visit; and when
    you were in France at the airport—in the airplane actually, the investigating
    judge, Mr. [Christian] De Valkeneer—I questioned him yesterday, he was
    here, he called you on your mobile phone and he said that it was 4:15 p.m.,
    and he said the next time you come to Belgium to see your husband, call me
    and I will organize a visit; and so you called him to give him a date, and he
    did the necessary to organize the visit in his office; and so I came to his
    office, and it was a big surprise, because I saw my baby, he was four months
    old, and that was the first time and the last time I saw him?
    [A.] Honestly, it’s been 22 years, and I don’t remember this incident exactly.
    12
    Q. Did I understand that you do not remember the first and the last time that my
    son saw me, is that it?
    A. I know that I did go to Belgium and that the judge was there, but the
    circumstances I don’t remember exactly.
    Q. I’m going to ask you a question, Madam Amal. [ am asking you to take all
    the necessary time to answer, because I want to move forward very, very
    quickly. So you have no recollection on a visit in Belgium, either in the
    judge’s office or in the jail, is that what I really understand?
    [A.] I said already that I don’t recall. I know I did go to Belgium. I know that
    there was the judge. I knew that Mr. Trabelsi saw his son. But the
    circumstances I no longer remember.
    Q. Do you remember coming to the jail or not? Do you remember going into a
    jail?
    A. I don’t remember exactly.
    Id. at 68-70. As explained in greater detail below, see infra at 53 & n.14, the deposition ended at
    around 4:40 p.m. on the first day—one hour and twenty minutes earlier than anticipated—when
    Trabelsi’s standby counsel stated on the record: “Your Honor, I’m sorry to interrupt, but the
    French prosecutor says they’re done for the day.” Jd. at 70.
    The second day of questioning proceeded much like the first. After a short delay in
    connecting with the witness on Jabber, Trabelsi began his cross-examination around 9:25 a.m.
    Apr. 27, 2023 a.m. Dep. (Tr. at 8). He spent the subsequent hour and forty-five minutes asking
    Ms. Amal, principally, about the legal status of her relationship with him, as well as about her
    relationships with prior romantic partners. The following exchange illustrates the nature of the
    questioning:
    Q. We are going to talk about our marriage. Do you recall that you said yourself
    about me this: “Of this man, I... currently expect a child. In regards to the
    Quranic law, I am married to this man. . . . [T]here was a ceremony before
    the imam with witnesses, two men. ...
    13
    A. So yes, I do remember this statement. But however, I was married to you,
    you know very well that you had said that I was married because of the
    Quran. I do remember this. But there was no ceremony. And according to
    Quranic law, yes, we were married. But according to French or German or
    Belgian or any other country’s law, we were not married. You only brought
    to me a piece of paper that said we were married from the imam. And Your
    Honor, this dates back to such a long time ago that I really have no memory
    of this.
    Q. I’m going to help you to remember this detail. Ms. Amal, do you know that
    it’s totally impossible for two human beings to get married without the
    signature of the other person, otherwise it’s not a marriage?
    [A.] When you get married, as far as I’m concerned, generally by law you get
    married at a city hall or at another place where you have an official marriage
    certificate. This piece of paper that you brought me from the imam doesn’t
    have any value, it’s not an official document as far as I’m concerned. I do
    agree that we spent time together, but that’s all.
    Q. Do you know that a religious wedding paper must be signed by you and me,
    but do you know—. . . If a marriage is recognized by God, it is a marriage[?]
    A. Mr. Trabelsi, this is between yourself and you. I don’t feel concerned about
    this. And I’m asking you to go on with your questions, please.
    Q. Mrs. Amal, you asked me to stop and to move forward. I apologize, but |
    have no intention to do so. Why? Because I’m in jail for 20 years—22
    years. And since I’ve met you... all my life has changed. So I’m going to
    keep asking questions about this marriage in detail.®
    Id. at 11-14. Judge Upadhyaya again “remind[ed] [Trabelsi] of [his] time today” and cautioned
    him “to use it wisely.” Jd. at 15. Trabelsi ignored that instruction, asking Ms. Amal about her
    childhood instead: “When you were in France,” he queried, “you made statements . . . with the
    FBI that you and your sister had been mistreated by your father who was hitting you and you had
    ° The transcript is filled with many more questions like these from Trabelsi; the questions
    highlighted in this section are, as a general matter, merely a selection.
    14
    been placed in a foster family; is that correct?” Jd. at 17. (The government objected to this line
    of questioning as “harassing and unnecessarily personal.” /d.). Again, a few minutes later: “Do
    you remember that you left [Dusseldorf] because you had no family, you had no friends and you
    went to a house for women at age 25, do you remember that?” Id. at 24. And, after eliciting that
    Ms. Amal married someone named “George Beyer” in 1999, id. at 29, Trabelsi repeatedly—and
    at length—pressed the witness about whether she was married to yet another man before
    marrying Mr. Beyer. He asked, for example:
    Q. Mrs. Amal, I am a human being, and I was married with you, you are my
    son’s mother and you swore to God to tell the truth. And God is the witness.
    Yesterday, you lied 19 times. I have proof that you lied. So I want to ask
    you again to pay special attention, because I don’t want you to have
    problems. I want you to think about things, because I have proof that you
    lied. So I’m asking you again, are you sure that you were never married
    before Mr. George Beyer?
    Q. Mrs. Amal, my question is this: In your mind, in your head, in your soul—
    and I’m thinking about the past, so you have no recollection of being married
    to your cousin, is that your testimony?
    Q. So here’s my question, ma’am: You stated clearly that you’ve never been
    married before marrying Mr. Beyer. So this is really clear, ma’am, that
    you’ ve used this marriage as a mean to an end. And you stated that you were
    not married, however you accused me of hitting you, of raping you. You
    consider me as a human being who does not exist, and all you are doing is
    hurting all of us.
    Id. at 30, 38, 45. Trabelsi then asked Ms. Amal about various letters that she sent to him in
    prison. He read at least one of the letters into the record, which prompted another reminder from
    Judge Upadhyaya: “[S]pending time reading into the record a long letter [when] . . . [the witness]
    understood Arabic [and read the letter herself], that time is going to cut against you. This is your
    15
    time, so just use it wisely. I’ve said it a million times, I’m going to keep reminding you.” Jd. at
    59.
    Although Trabelsi moved on from the letter, he ignored the import of Judge Upadhyaya’s
    advice and started questioning the witness about their relationship dynamic. He asked:
    Q. I want to ask you if you remember in June 2001 we had a conversation in
    Afghanistan, and you were—you had been pregnant and you had lost the
    baby. And I wanted to have four girls, and you wanted to have two boys and
    two girls. And I proposed you to authorize me to marry another woman, and
    you got very upset and you started crying and you were very upset and you
    threatened me. Do you remember that?
    Q. Do you know that many Muslim men have the right to get married again and
    again and again, they don’t even ask permission from their wife to get
    married?
    Q. My next question: Were you a jealous woman?
    Q. So when you married me, did you observe that I was always wearing very
    fancy clothes like Europeans?
    Q. So my question is very clear: Can you confirm that you were young, that you
    were a professional manipulator, yes or no?
    Id. at 64-66, 74. Before the lunch break, Judge Upadhyaya again cautioned Trabelsi to “start
    asking her questions instead of simply making statements on the record, which is really
    testimony by you.” Id. at 75. “At this point,” she observed, “there have been some topics which
    you have gone into over and over and over again,” and she cautioned, “as you think about over
    this next break what questions you’re going to ask next, keep in mind how much time you have
    left and ask your questions accordingly.” Jd. at 83.
    16
    But Trabelsi continued, after the lunch break, to use his questions to testify—this time,
    about the beginning of their romantic relationship. He began:
    Q. I met you on March 17, 2006, between 5 p.m. and 6 p.m. Do you remember
    that you were in a phone booth, speaking to a relative, and you were crying?
    A. I don’t remember exactly.
    Q. Thank you. Thank you. I heard something. Because I saw a woman who
    was crying, so I offered my aid, my help. . . . So, we offered, myself and
    another brother, to go gather some coffee, to know what you’re worried
    about—to know what your suffering was, so we could find a solution to help
    you.
    A. I remember that we had—we had a little bit of an exchange, we exchanged
    a few words. But regarding the details and the circumstances, I no longer
    recall the details.
    Q. Thank you. Thank you. So you told us your story. You said you had two
    problems, the first one was that your boyfriend was beating you. The second
    one was that you had been raped by the owner of your mother’s house in
    Corsica and that is why you went to Germany, is that right?
    A. As I said, Mr. Trabelsi, | don’t remember exactly what . . . had happened,
    what occurred, the details. [ know we exchanged some words. But this story
    that you’re telling, I don’t know if it’s something that you have invented. |
    know that we had an exchange of a few words, but regarding the details of
    what it was that was said, I no longer remember.
    Apr. 27, 2023 p.m. Dep. (Tr. at 9-10). Trabelsi’s questioning continued as such for much of the
    afternoon. A few minutes later he asked, again:
    Q. So do you remember that—something you said in D.C., in 2007: So when
    you came back from Morocco and you arrived at the airport in Dusseldorf,
    and I was calling you. And your boyfriend was there with his son. And so
    that was at the airport, that you were very surprised, and that’s when you
    decided to come with me, instead of your boyfriend. Do you remember that?
    17
    [A.] Once again, I don’t recall.
    Q. When... you came back from Morocco and you got to the airport, I was
    waiting for you. ... And your ex-boyfriend, the violent one, was there also
    with his son. And we got out, we went to the parking lot, and when we got
    to my car, I got out a weapon and I threatened him if he was getting close to
    you. Do you remember that?
    A. [do remember that Mr. Trabelsi did have weapons and that he did threaten
    me. I remember that he had weapons and he had threaten several times, but
    when exactly I don’t know. And he’s continuing harassing. But regarding
    the trip to Morocco, yes, I remember coming back. But who exactly came
    to pick me up, that I don’t have any recollection of anymore.
    Id. at 12-16. After a brief interlude, Trabelsi returned, again, to their purported marriage:
    Q. Do you remember that I agreed to your marriage proposal and I started
    buying you furniture for the apartment?
    A. I remember that you came to my apartment and that we talked, but I don’t
    remember things in such detail.
    Q. [A]s you know, for religious reasons, we could not have relationship or have
    children out of wedlock without being married first?
    MR. TORTORICE: Objection. Form.
    Q. If memory serves me right, we met a few times, several times. Do you
    remember telling me at the onset that we were going to be a family, just like
    everyone else, and we hope that God will heal us?
    A. I don’t recall exactly what I had said to you, but we did talk together. But
    specifically, I don’t remember what we said.
    Q. Do you remember telling the FBI, in 2007, in Washington, D.C., that we
    went to see the [i]mam so that we could prep for the wedding?
    MR. TORTORICE: Objection. Form.
    A. I don’t precisely recall what I said, Your Honor.
    Id. at 30-31. After a reminder from Judge Upadhyaya that “she’s answered your question a
    couple different ways,” id. at 32, Trabelsi continued:
    18
    Q. Is it clear that you’ve stated that you’ve never been married? Yes or no?
    A. I’ve already answered this question.
    THE COURT: What was your previous answer, please?
    [A.] I don’t recall, Your Honor. This goes back such a long time.
    Q. So, right now, you persist on saying this. It is your testimony that you were
    never married to me?
    THE COURT: Mr. Trabelsi, it’s the last question on the topic. She can answer.
    [A.] I state again, just like before, we were never officially married. We were
    married, according to you, according to [Quranic] law, but you said you
    have a document. But as far as I’m concerned, you’re only my son’s father
    and nothing else. You were never my husband.
    Id. He also revisited Ms. Amal’s visit to him in prison: “Ma’am,” he queried, “do you remember
    meeting me at the judge’s office, accompanied with our son? And I came to see you and this
    was at your request.” Jd. at 39.
    The government moved to end the deposition around 4:00 p.m. EST on the second day.
    Id. at 49. “[T]he government’s direct examination was a little under three hour[s],” counsel
    explained, and “Mr. Trabelsi has now been going for a little over six hours.” Jd. at 49-50.
    Government counsel noted, moreover, that Trabelsi had not “made effective and efficient use of
    his time. He has read from documents at length that there has been no proper foundation laid for.
    He has asked questions, sometimes up to ten minutes.” Jd. at 50. In response, Trabelsi’s standby
    counsel represented that Trabelsi had “a number of buckets” to explore further, including (1)
    “the issue of [the witness’s] unavailability” at trial; (2) “threats and promises that were made to
    her related to this case;” and (3) the fact that “the witness has said clearly that she takes the
    19
    position that they were never married.” /d. at 62. Judge Upadhyaya denied the government’s
    motion and allowed Trabelsi to continue asking questions of the witness. Id. “[Y]ou’ve got
    those topics to cover and you’ve got to get it done,” Judge Upadhyaya explained to Mr. Trabelsi.
    Id. at 63.
    After that reprieve and six hours into his cross-examination, Trabelsi asked Ms. Amal
    several relevant questions about whether she “received money from the U.S. government related
    to [his] case,” id. at 63; whether she “receive[d] any support, any help from the U.S. government
    or the French government for a new passport in Montpellier,” id. at 65-66; and whether she now
    had French citizenship, id. at 72. He further explored her “arrest[] on September 15th, 2001;”
    whether she was “afraid of getting arrested,” id. at 73; and whether she had been “charged with
    the association of criminals” at the time, id. at 74. He questioned, moreover, whether Ms. Amal
    “changed [her] story” and “started telling things that [she] had never told before” to the U.S.
    government after they “told [her] that [she] should be truthful with them and they will help
    [her].” Jd. at 77. But he also returned, yet again, to whether they were “religious[ly] marr[ied]”
    and, when Ms. Amal testified that they “ha[d] never been officially married,” Trabelsi stated that
    he “want[ed] Allah to hear [her] testimony . . . because if [she] said that, then [she] committed
    adultery and... had a child out of wedlock.” Jd. at 78. “Do you realize that saying that you are
    not married,” he continued, “and you have God as witness—that you committed adultery
    because you had a child with me out of wedlock?” Jd. at 79. (The government, once again,
    objected that “this line of questioning is harassing and intimidating.” Jd. at 79.). He also asked
    Ms. Amal some questions about when, exactly, she identified the U.S. embassy in Paris as the
    alleged target of his plot, id. at 81-82; about why she told investigators in September 2001 that
    20
    she had “never heard anything” about a plot against the U.S. embassy, id. at 83, 85; and about
    her previous statements that they had gone to Afghanistan “to help poor people,” id. at 88-89.
    At 6:03 p.m. EST—shortly after midnight in France—the French prosecutor stated that
    “we will have to stop now.” Jd. at 91. She explained, “In France, [one is] not . . . allowed to
    question a witness more than four hours,” and, here, “[t]he witness was interrogated six hours
    yesterday, seven hours today.” Jd. at 91-92. Standby counsel objected that “for the first time
    we’ ve heard that it’s being ended pursuant to French law, which would be a whole new issue and
    a whole new wrinkle that we would have to tackle,” id. at 92, and asked Judge Upadhyaya to
    “order [the witness] to continue to answer questions,” id. at 94. The Court explained that
    “It]here was an agreement to go until 6 p.m.” and noted that the Court “gave him much more”
    than “two times the amount of time that the government had.” Jd. at 96. The deposition ended at
    6:18 p.m. EST. Jd. at 99.
    C. After the Deposition
    At the next motions hearing, standby counsel indicated that counsel would be filing, on
    Trabelsi’s behalf, a motion to “continue the deposition under the [C]onfrontation [C]lause or . . .
    to strike the entire testimony.” May 1, 2023 Hrg. Tr. (Rough at 164). The Court explained
    that—to the extent Trabelsi “feels as though there were topics that he did not have time to
    cover”—the Court would “need to know with real specificity what those were,” including
    exactly which “relevant and important questions” Trabelsi did not have time to ask. Jd. at 166.
    The Court also emphasized, repeatedly, that “the best thing would be if the witness could make
    herself available for some additional limited examination” because the government would,
    otherwise, “run the risk that [the deposition is] not going to come in.” Id. at 166-67.
    21
    The next day, Trabelsi moved to relinquish his Faretta rights: he explained that he
    “realized .
    . .in the last three weeks” that he could not “be [his] own lawyer.” Dkt. 586. Before
    ruling on that motion, the Court heard Trabelsi’s proffer as to “what questions he still wanted to
    ask of Ms. Amal and didn’t have a chance to ask . . . at her deposition.” May 3, 2023 Hrg. Tr.
    (Rough at 2). He represented, without detail as to how he would do so, that he wanted to address
    the following topics, among other issues:
    “I know that Ms. Amal was charged in... 2002 and. . . I found evidence that she
    was charged with a criminal association with intention of committing an attack. So I
    want to ask questions on that.” Jd. at 4.
    “[S]he stated that . . . I had watched videos of attacks in Nairobi that killed... U.S.
    and Muslim people and she said that I was very happy that I laughed when I saw
    these videos[.] . . . I want to show her from the phone conferences that I had after
    9/11 where I was very sad . . . and so I want to show she lied about talking about
    these attacks.” Jd. at 5.
    “I want to ask .. . about her statements that she made all the time from 2001 to 2005,
    and I want to talk about the [humanitarian] work I did in Afghanistan and actually
    she was there herself took part in that.” Jd. at 5.
    “T want to talk about . . . the last will and testament[.] . . . [SJhe stated that I signed a
    document because I was going to die and she was going to get everything that I had,
    and I want to show that she lied. In fact, I never signed any document... .” Jd. at
    9-10.
    “T want to ask her [about] my relation with [Jamal Beghal] and [Jerome
    Courtailler][.] ... So, she’s accusing them of being my accomplices, which is false.”
    Id. at 10.
    “T want to ask questions about . . . [the] passport .. . [and] about . . . the 20 counts for
    women in Afghanistan, which don’t exist .. . . [and] about the allegations . . . [that]
    several people in her life . . . hit{] her and beat[] her... . I never hit her. I never beat
    her... . I want to ask questions about the . .. wedding of... bin Laden’s son. And
    her relationship with bin Lad[e]n and his wife she never met any wife of his...
    that’s craziness.” Jd. at 10-12.
    “T also want to ask questions about her bank account before she married me . . . so I
    want to [show] Ms. Amal is a big criminal, big manipulator, and she really took
    advantage of me to steal money.” Jd. at 12.
    “I want to ask two questions about how she tried to get some money from somebody
    while I was in jail.” Jd. at 13.
    22
    e “I want to ask questions about the chemicals that she said she saw with her own eyes
    ... in my house, which is false.” Jd.
    e “I want to ask also about several letters [she] sent to me when she says clearly that I
    am incapable of hurting anybody or anything, not even a fly.” Id.
    e “I want to show her all these statements that she gave when she was not under the
    influence of the French government. ... Just to show how dangerous she is... .
    And to ... ask for at least to stop lying and if she pass at least the lie detector test.
    And also to ask finally why was she proud to be married and she pronounce the word
    married [] 176 times. And what happened after my arrest for her to change
    completely her behavior.” Jd. at 16-17.
    The next day, on May 4, 2023, the Court granted Trabelsi’s motion to relinquish his
    Faretta rights and to appoint his standby counsel as counsel “for purposes of his upcoming trial.”
    See Min. Order (May 4, 2023). That same day, the government filed a motion to admit the
    deposition of Ms. Amal at trial. Dkt. 588. Defense counsel cross-moved the following day to
    strike her testimony or, in the alternative, to continue the Rule 15 deposition. Dkt. 590. Defense
    counsel argued that “Trabelsi did not receive a fair opportunity to conduct a meaningful
    examination of Ms. Amal” and proffered a new list of “topics Mr. Trabelsi [would] seek to cover
    in additional testimony,” including “statements Ms. Amal made about her lack of knowledge of
    Mr. Trabelsi’s activities in Afghanistan,” her cooperation and interactions with Belgian, French,
    and U.S. law enforcement officers, her availability to travel to the United States for trial, the
    “status of their relationship between 2000 and 2002 . . . [and] statements Ms. Amal made about a
    religious marriage with Mr. Trabelsi in 2000,” “illegal conduct by Ms. Amal before she met Mr.
    Trabelsi,” and “Ms. Amal’s contact with Mr. Trabelsi after his arrest.” Dkt. 590 at 6-7. The
    defense argues that, absent further examination on these topics, admitting the deposition “would
    violate, both facially and as applied, Mr. Trabelsi’s Sixth Amendment right under the United
    States Constitution to confront Ms. Amal.” Jd. at 8.
    23
    The government, meanwhile, endeavored to make Ms. Amal available for further cross-
    examination by Trabelsi. On May 10, 2023, government counsel wrote to their French
    counterparts (through whom the government communicates with the witness) and explained:
    [O]ur Judge has expressed his grave concerns about whether or not to allow Ms.
    {Amal]’s deposition to be shown to the jury. The Judge believes it would be
    better to allow the defense attorney to question Ms. [Amal] for a few more hours.
    If she agrees to answer more questions, it would be the defense attorney asking
    the questions, not Mr. Trabelsi, so the process should go much smoother and be
    much shorter. In brief, I am asking you whether Ms. [Amal] will agree to answer
    questions for a few more hours. Indeed, I’m urging you to ask Ms. [Amal] if
    she will agree to it....
    I completely understand and respect Ms. [Amal]’s deep reluctance to testify
    again. I realize it was a great burden on her psychologically, and I respect the
    tremendous strength and courage she showed during the deposition. But it is so
    important that the jury hears this evidence. If it is suppressed, it would be a
    tragedy. It would be a terrible, miscarriage of justice. Her testimony is
    powerful, and we want to be sure the jury has the opportunity to hear it.
    I realize this is a delicate subject to discuss with Ms. [Amal], but the sooner we
    can get an answer from her, the sooner our Judge can make his decision. We
    hope you will be able to speak with her this week.
    Dkt. 600-2 at 2-3. The next day, on May 11, 2023, the French officials responded:
    We fully understand the issue of this hearing, but we will not be able to respond
    favorably to your request.
    We contacted Ms. [Amal] who categorically refused to participate in a new
    witness hearing. She told us that she was no longer in a psychological state to
    participate in such an exercise and told us that she experienced a major
    depressive event following her two days of particularly trying hearings before
    the American Court. She says she answered all the questions and has nothing
    more to say. Her answer is unequivocal and can only be respectéd in view of
    the commitments made to her.
    Id. at 1.
    In an ideal world, of course, Trabelsi—or, even better, the lawyers who now serve as his
    counsel—would have had a further opportunity to cross-examine Ms. Amal, even if such cross-
    examination is not required under the Confrontation Clause. In general, it is better to err on the
    24
    side of giving a defendant—and particularly a pro se defendant—substantial leeway in cross-
    examining a key witness. But in light of Ms. Amal’s “categorical[] refus[al]” to submit to
    further questioning, id., and the fact that she is beyond this Court’s subpoena power, the Court
    cannot simply decide, as a matter of discretion, to continue the deposition for another hour or
    two—merely to err on the side of caution or forbearance for a pro se defendant. Instead, the
    Court must determine whether admitting the video-taped Rule 15 deposition as-is comports with
    Trabelsi’s rights under the Sixth Amendment.
    II. ANALYSIS
    The Sixth Amendment guarantees that, “[i]n all criminal prosecutions, the accused shall
    enjoy the right . . . to be confronted with the witnesses against him.” U.S. Const. amend. VI.
    “Courts have long recognized the critical importance of a criminal defendant’s ‘opportunity to
    cross-examine and impeach a witness at trial before the jury that will decide his innocence or
    guilt.’” United States v. Burden,

    , 685 (D.C. Cir. 2019) (quoting United States v.
    Lynch, 
    499 F.2d 1011
    , 1022 (D.C. Cir. 1974)). The long-established right to a witness’s live
    testimony in the courtroom gives the defendant an opportunity “not only of testing the
    recollection and sifting the conscience of the witness, but of compelling him to stand face to face
    with the jury in order that they may look at him, and judge by his demeanor upon the stand and
    the manner in which he gives his testimony whether he is worthy of belief.” Mattox v. United
    States, 
    156 U.S. 237
    , 242-43 (1895). But the right to a witness’s presence at trial is not absolute.
    The testimony of a witness who does not appear at trial is admissible if (1) the witness “is
    unavailable” to testify at trial and (2) “the defendant has had a prior opportunity to cross-
    examine” that witness. Crawford v. Washington, 
    541 U.S. 36
    , 59 (2004); see also Fed. R. Evid.
    25
    804(b)(1). Trabelsi contends that neither condition is satisfied here, and the Court, accordingly,
    takes up each prong in turn.
    I. Unavailability
    To establish a witness’s unavailability under Crawford and Fed. R. Evid. 804(b)(1), the
    prosecution bears the burden of showing that it “cannot procure her with good-faith, reasonable
    efforts.” Burden, 
    934 F.3d at 686
    . Although there is substantial overlap between this standard
    and the unavailability inquiry under Fed. R. Crim. P. 15 that the Court considered in its prior
    opinion, see Dkt. 578, Crawford requires a more definitive showing of unavailability than Rule
    15. In authorizing the deposition, the Court considered not whether the government had
    established that it “cannot procure” Ms. Amal’s attendance at trial, but only whether there was a
    “substantial likelihood” that Ms. Amal “w[ould] not testify at trial.” Dkt. 578 at 6 (quoting
    United States v. Drogoul, | F.3d 1546, 1553 (11th Cir. 1993)); see also Drogoul, | F.3d at 1553
    (“It would be unreasonable and undesirable to require the government to assert with certainty
    that a witness will be unavailable for trial months ahead of time, simply to obtain authorization
    to take his deposition.” (quoting United States v. Sines, 
    761 F.2d 1434
    , 1439 (9th Cir. 1985))).
    But even under this higher standard, “[t]he lengths to which the prosecution must go to
    produce a witness . . . is a question of reasonableness.” Ohio v. Roberts, 
    448 U.S. 56
    , 74 (1980),
    abrogated in part on other grounds by Crawford, 
    541 U.S. at 60-69
    . “‘The law does not require
    the doing of a futile act’ such as producing a witness who has died, but ‘if there is a possibility,
    albeit remote, that affirmative measures might produce the declarant, the obligation of good faith
    may demand their effectuation.”” Burden, 
    934 F.3d at 686
     (emphasis in original) (quoting
    Roberts, 
    448 U.S. at 74
    ). “At least where the evidence indicates that a crucial government
    witness .. . is within the jurisdiction of the court, the prosecution must demonstrate that it has
    26
    been unable to obtain the witness’ presence through a search exercised both in good faith and
    with reasonable diligence and care.” United States v. Lynch, 
    499 F.2d 1011
    , 1023 (D.C. Cir.
    1974); see also United States v. Vo, 
    53 F. Supp. 3d 77
    , 81 (D.D.C. 2014) (explaining that Fed. R.
    Evid. 804(a) provides “that a witness is unavailable if he or she is absent from the hearing and
    the proponent of a statement has been unable to procure the declarant’s attendance . . . by process
    or other reasonable means” (quoting United States v. Straker, 
    567 F. Supp. 2d 174
    , 180 (D.D.C.
    2008))). Mere “possibility” that the witness might “refus[e]” a request to testify, moreover, “is
    not the equivalent of asking and receiving a rebuff.” Roberts, 
    448 U.S. at 76
     (internal quotation
    marks omitted).
    Here, the question is not whether the prosecution has searched for Ms. Amal “in good
    faith and with reasonable diligence.” Lynch, 
    499 F.2d at 1023
    . Although the government is
    well-aware of Ms. Amal’s location, she is a foreign national living in France and is, accordingly,
    beyond the Court’s subpoena power. Under Federal Rule of Criminal Procedure 17(e)(2), “Tilf
    the witness is in a foreign country, 
    28 U.S.C. § 1783
     governs the” service of a trial subpoena.
    Section 1783, however, applies only to witnesses who are “national[s] or resident[s] of the
    United States” and who are overseas at the time of trial. 
    28 U.S.C. § 1783
    (a); see FTC v.
    Compagnie De Saint-Gobain-Pont-a-Mousson, 
    636 F.2d 1300
    , 1320 n.116 (D.C. Cir. 1980)
    (explaining that the statute “has never been read as permitting issuance of a subpoena to an alien
    residing outside the United States”). Ms. Amal, moreover, has repeatedly and emphatically
    refused to travel to the United States to testify at Mr. Trabelsi’s trial. Although she had, at one
    point in 2017, been “willing, although reluctant, to testify at trial in person,” Dkt. 501 at 10, that
    is no longer her position. On March 31, 2023, the prosecutors met with Ms. Amal in France,
    where she was—according to an FBI-302 presented by the parties to the Court—“adamant [that]
    27
    she did not want to travel to the United States to testify in the trial,” see Apr. 19, 2023 Hrg. Tr.
    (Rough at 36) (discussing this FBI-302), notwithstanding the prosecutor’s apparently “long,
    diplomatic face-to-face discussions with [her] about the importance of her testimony,” Dkt. 570-
    | at 2; see also Apr. 19, 2023 Hrg. Tr. (Rough at 30) (representation by government counsel that
    he was “in the room with [Ms. Amal] . . . and [that] she was in tears and told us that she is not
    willing to come to the United States to testify”). Moreover, government counsel asked Ms. Amal
    at the Rule 15 deposition on April 26, 2023 whether she was “willing to travel to the United
    States to testify in this proceeding;” she answered, without hesitation, “No, I can’t come.” Apr.
    26, 2023 a.m. Dep. (Tr. at 12). She also confirmed, in response to questions from Trabelsi
    himself, that she would “refuse[] to come to the trial” and that she “cannot come to Washington,
    to the trial, because [she] ha[s] several sick children who need [her] 24 hours a day.” Apr. 27,
    2023 p.m. Dep. (Tr. at 57-58). And lastly, the French prosecutors confirmed, in an email to the
    U.S. government prosecutors on May 11, 2023, that Ms. Amal was “categorically refus{ing] to
    participate in a new witness hearing” after “experienc[ing] a major depressive event following
    her two days of particularly trying hearings before the American Court.” Dkt. 600-2 at 1.
    Trabelsi does not dispute that the Court lacks means to compel Ms. Amal’s attendance at
    trial; nor has he identified any law that would allow the Court to compel her attendance. He
    contends, rather, that “Ms. Amal’s claimed justification [for her inability to attend] is [both]
    inadequate on its face” and “squarely contradicted by the fact that Ms. Amal’s children were all
    at home, and ably cared for by an individual paid by the U.S. government, while Ms. Amal was
    at her Rule 15 deposition.” Dkt. 590 at 9-10. The Court, however, has no reason to doubt Ms.
    Amal’s sworn testimony that her children “need [her] 24 hours a day,” Apr. 27, 2023 p.m. Dep.
    (Tr. at 57-58), and, in any event, “it is not the Court’s job to adjudicate whether . . . [Ms. Amal]
    28
    should attend trial,” United States v. Abu Khatallah, 
    282 F. Supp. 3d 279
    , 282 (D.D.C. 2017).
    “Rather, where a witness cannot be compelled by legal process to attend trial, the only question
    is whether the proponent of the deposition has made reasonable, good-faith efforts to make h[er]
    available.” Jd. (citing Barber v. Page, 
    390 U.S. 719
    , 725 (1968)); see also United States v.
    Sanford, Ltd., 
    860 F. Supp. 2d 1
    , 4 (D.D.C. 2012) (“A witness who resides abroad and outside
    the reach of a court’s subpoena power is not automatically ‘unavailable’ without a further
    showing that he or she will not testify in court.” (quoting United States v. Warren, 
    713 F. Supp. 2d 1
    , 4 (D.D.C. 2010)); United States v. Siddiqui, 
    235 F.3d 1318
    , 1323-24 (11th Cir. 2000)
    (concluding that two witnesses were unavailable and admitting their prior Rule 15 depositions
    where the witnesses testified, respectively, that it would be “impossible for [the first witness] to
    travel to the United States for trial” and that “[the second witness] d[id not] want to go, if
    possible”). Cf Hamilton v. Morgan, 
    474 F.3d 854
    , 859 (6th Cir. 2007) (“If the desired witness is
    beyond the subpoena power of the trial state but an established procedure of voluntary
    cooperation exists, then the government must go to reasonable lengths to utilize that procedure to
    locate, contact, and arrange to reasonably transport the witness.”).
    Where, as here, the government has made “reasonable, good-faith efforts” to secure the
    foreign witness’s availability and is nevertheless rebuffed, the limits of the Court’s subpoena
    power leave the government with no further recourse. See, e.g., United States v. Medjuck, 
    156 F.3d 916
    , 920 (9th Cir. 1998) (concluding that “the Canadian witnesses were unavailable for trial
    because they were beyond the subpoena power of the United States and refused voluntarily to
    attend”); United States v. Farfan-Carreon, 
    935 F.2d 678
    , 680 (5th Cir. 1991) (noting, in the Rule
    15 context, that a witness was “beyond the subpoena power of the court, and could not be
    compelled to appear” because he was “a Mexican national” living abroad). In short, given Ms.
    29
    Amal’s refusal to testify at trial, the Court fails to discern—and the defense fails to suggest—any
    further steps that the prosecutors reasonably could have taken to bring the witness before the
    jury. See Burden, 
    934 F.3d at 686
    ; see also Medjuck, 
    156 F.3d at 920
     (“There is no requirement
    that the Government go through a futile exercise before it may proceed to arrange for a
    defendant’s remote participation.”). “[H]aving taken reasonable (but ultimately unsuccessful)
    steps to make [Ms. Amal] available, the Government has shown that [s]he is unavailable for
    trial.” Abu Khatallah, 282 F. Supp. 3d at 283.
    2. Opportunity for Cross-Examination
    The Court, next, turns to the question of whether Trabelsi “has had a prior opportunity to
    cross-examine” the witness. Crawford, 
    541 U.S. at 59
    . Neither party contests that Trabelsi did,
    in fact, cross-examine Ms. Amal during her Rule 15 deposition on April 26 and 27, 2023. The
    question is only “whether the confrontation that occurred is constitutionally sufficient.” United
    States v. Yates, 
    438 F.3d 1307
    , 1314 n.4 (1 [th Cir. 2006) (en banc). Trabelsi argues that it was
    not, contending both that he was impermissibly denied the opportunity to confront Ms. Amal
    “face to face” during the deposition and that he was provided with insufficient time to conduct a
    constitutionally adequate cross-examination. Dkt. 590 at 10 (arguing that the deposition did not
    “pass[] constitutional muster”). The defense asserts that this inquiry is governed by the standard
    articulated in Maryland v. Craig, 
    497 U.S. 836
     (1990), where the Supreme Court held that “a
    defendant’s right to confront accusatory witnesses may be satisfied absent a physical, face-to-
    face confrontation at trial only where [(1)] denial of such confrontation is necessary to further an
    important public policy and [(2)] only where the reliability of the testimony is otherwise
    assured” —i.e., where the “other elements of confrontation” were guaranteed. Jd. at 850-51.
    30
    Neither the Supreme Court nor the D.C. Circuit have considered whether the Craig
    standard, which was announced in analyzing whether live video testimony during trial is
    permissible, also governs the question of whether video testimony taken during a pre-trial Rule
    15 deposition is admissible under Crawford and the Confrontation Clause. For present purposes,
    the Court need not decide this question and, instead, assumes that the Craig standard governs
    whether a “confrontation that occurred” over video before trial “is constitutionally sufficient”
    under Crawford. Yates, 
    438 F.3d at
    1314 n.4; see 
    id.
     (explaining that Crawford alone “does not
    answer th[e] question” of whether pretrial, remote testimony constituted “an opportunity to
    cross-examine”); see also United States v. Abu Ali, 
    528 F.3d 210
    , 240 (4th Cir. 2008) (applying
    Craig in considering the admissibility of a remote Rule 15 deposition at trial).’
    All agree that “the Confrontation Clause reflects a preference for face-to-face
    confrontation at trial”—a preference that, under the Craig standard, “must occasionally give way
    to considerations of public policy and the necessities of the case.” 
    497 U.S. at 849
     (first quoting
    Roberts, 
    448 U.S. at 63
    ; then quoting Mattox, 
    156 U.S. at 243
    ). But the fact “[t]hat the face-to-
    7 The parties also agree—as does the Court—that the Craig test governs notwithstanding the fact
    that Ms. Amal testified via two-way closed-circuit televised video (“CCTV”) and not, as in
    Craig, one-way CCTV (which did not allow the witness to see the defendant). With the
    exception of the Second Circuit, see United States v. Gigante, 
    166 F.3d 75
    , 79-82 (2d Cir. 1999),
    the Courts of Appeals that have considered the issue have, generally speaking, applied Craig to
    remote two-way CCTV testimony in Rule 15 depositions or during trial, see, e.g., Abu Ali, 
    528 F.3d at 240-41
    ; Horn v. Quarterman, 
    508 F.3d 306
    , 319 (Sth Cir. 2017); United States v.
    Wandahsega, 
    924 F.3d 868
    , 879 (6th Cir. 2019); United States v. Bordeaux, 
    400 F.3d 548
    , 553-
    54 (8th Cir. 2005); United States v. Carter, 
    907 F.3d 1199
    , 1205-07 (9th Cir. 2018); Yates, 
    438 F.3d at 1312-13
    . That view is bolstered, moreover, by the Supreme Court’s 2002 rejection of a
    proposed revision to Fed. R. Crim. P. 26, which would have allowed testimony by two-way
    CCTV; Justice Scalia’s separate statement on the issue explained that such a proposal was “of
    dubious validity under the Confrontation Clause” because it failed to “limit the use of testimony
    via video transmission to instances where there has been a ‘case-specific finding’ that it is
    ‘necessary to further an important public policy.’” Order of the Supreme Court, 
    207 F.R.D. 89
    ,
    93 (2002) (statement of Scalia, J.) (quoting Craig, 
    497 U.S. at 850, 857-58
    ).
    oll
    face confrontation requirement is not absolute does not . . . mean that it may be easily dispensed
    with.” Jd. at 850. Rather, “a defendant’s right to confront accusatory witnesses may be satisfied
    absent a physical, face-to-face confrontation at trial only where [(1)] denial of such confrontation
    is necessary to further an important public policy and [(2)] only where the reliability of the
    testimony is otherwise assured”—i.e., where the “other elements of confrontation” were
    guaranteed. 
    Id. at 850-51
    . In Craig itself, the Supreme Court approved a Maryland state court’s
    use of one-way, closed-circuit televised video technology for a six-year-old child victim of
    sexual abuse to testify at trial; the Court concluded that “a State’s interest in the physical and
    psychological well-being of child abuse victims may be sufficiently important to outweigh, at
    least in some cases, a defendant’s right to face his or her accusers in court.” Jd. at 853.
    Moreover, the Supreme Court explained, the “other elements of confrontation”—including an
    oath, a “full opportunity for contemporaneous cross-examination,” and the jury’s ability to view
    “the demeanor (and body) of the witness as he or she testifie[d]”—“adequately ensure[d] that the
    testimony [was] both reliable and subject to rigorous adversarial testing in a manner functionally
    equivalent to that accorded live, in-person testimony.” 
    Id. at 851
    ; cf, Crawford, 
    541 U.S. at 57
    (describing cross-examination as the “single safeguard” that “the Confrontation Clause
    demands”).
    Trabelsi contends that Ms. Amal’s deposition, which occurred via two-way video
    conferencing, is inadmissible because neither prong of Craig is satisfied. First, he argues that no
    “important public policy” is served by depriving him of a face-to-face confrontation with Ms.
    Amal: “Being available to her adult child (as Ms. Amal asserted at her deposition) or a past
    incident involving two of her minor children (as the government claimed to the Court),” he
    contends, “are insufficient to meet the requirement under Craig.” Dkt. 590 at 11 (italicization
    32
    added). Second, he asserts that, unlike in Craig, the “‘reliability’ of Ms. Amal’s testimony [i]s
    not assured because she was not ‘subject to rigorous adversarial testing in a manner functionally
    equivalent to that accorded live, in-person testimony.”” Jd. at 12 (quoting Craig, 497 U’S. at
    851). The Court considers each of these issues in turn.
    a. Public Policy Rationale
    “The requisite finding” that denying Trabelsi a face-to-face confrontation with Ms. Amal
    is “necessary to further an important public policy” must “be a case-specific one,” Craig, 
    497 U.S. at 850, 855
    , and the “public interest” reason for doing so must be “more substantial than
    [the interest in] convicting someone of a criminal offense,” Abu Ali, 
    528 F.3d at 241
    . The Court
    must articulate, in other words, a reason that is more particularized than the “need . . . to make a
    case” or “to expeditiously resolve it.” Yates, 
    438 F.3d at 1316
    . The en banc Eleventh Circuit’s
    decision in United States v. Yates, 
    438 F.3d 1307
     (11th Cir. 2006) (en banc), is instructive on this
    point. There, “the district court applied the Craig test to permit [two] Australian witnesses to
    testify by two-way video conference broadcast on a television monitor at trial . . . based only on
    the [g]overnment’s assertions . . . that the Australian witnesses were unwilling to travel to the
    United States.” 
    Id. at 1315
    . The government had, at the time, proposed several “public interest”
    reasons that purportedly necessitated remote testimony, including “providing the fact-finder with
    crucial evidence, expeditiously and justly resolving the case, and ensuring that foreign witnesses
    can so testify.” 
    Id. at 1315-16
     (internal quotation marks and citations omitted). The en banc
    Eleventh Circuit reversed, emphasizing that the government’s proposed “public interest”
    reasons—if credited—would apply equally to any “criminal prosecution in which the
    Government would find it convenient to present testimony by two-way video conference.” Jd. at
    1316. These justifications were particularly weak, the court further explained, because “there
    33
    [was] no evidentiary support [in the record] for a case-specific finding that the witnesses and
    [d]efendants could not be placed in the same room for the taking of pre-trial deposition
    testimony pursuant to [Fed. R. Crim. P.] 15.” Jd. at 1317. Significantly, there was nothing in
    that case “prevent[ing] the [d]efendants from traveling to Australia to be present for a Rule 15
    deposition.” Jd. at 1318. A similar principle governed the Ninth Circuit’s decision in United
    States v. Carter, 
    907 F.3d 1199
     (9th Cir. 2018), where the court concluded that a witness’s
    difficult pregnancy did not justify her remote testimony at the defendant’s trial, since the court
    could have merely “continue[d] the trial” for “the duration of her pregnancy (which was two
    months)” in “anticipation of [her] recovery,” 
    id. at 1208
     (internal quotation marks and citations
    omitted).
    Yates and Carter instruct, then, that courts may not permit remote testimony if securing a
    face-to-face confrontation is possible—even if doing so is more logistically complicated than the
    alternative (because it requires, for example, that the Court delay trial by a few months, see 
    id. at 1208
    , or that the government transport the defendants abroad for such confrontation, see Yates,
    
    438 F.3d at 1318
    ). In Trabelsi’s view, Ms. Amal’s stated need to “be[] available” to her children
    falls closer to a logistical convenience than to the kind of “public policy” interest that
    necessitates remote testimony—especially because Ms. Amal did not describe “the injuries to
    [her] minor children . . . as permanent] or so serious that no alternative could be found that
    addressed both Ms. Amal’s concerns and Mr. Trabelsi’s constitutional rights.” Dkt. 590 at 11—
    12.
    Trabelsi has not, however, proposed a satisfactory “alternative.” Nor could he do so.
    Here, unlike in Carter and Yates, the Court could not have simply delayed trial—or ordered the
    government to transport Trabelsi to France—to facilitate a face-to-face confrontation between
    34
    him and Ms. Amal. To the contrary, as described above, Ms. Amal is beyond the Court’s
    subpoena power and has repeatedly and consistently refused to travel to the United States either
    for a deposition or for live testimony at trial. She categorically declined to travel to the United
    States before, see Dkt. 570-1 at 2, and during the deposition, see Apr. 26, 2023 a.m. Dep. (Tr. at
    12)—and has, since the deposition, “categorically refus[ed] to participate” in any “new witness
    hearing,” Dkt. 600-2 at 1. Delaying the trial would not resolve that problem, and, in any event,
    as the Court has repeated explained, delaying the start of this trial was not a realistic option
    because it would have resulted in the government’s loss of at least one essential witness, who is
    outside the subpoena power of the United States and who indicated that, given the numerous
    continuances and false starts in this matter and his competing obligations, he would decline to
    appear at trial, if his appearance was postponed yet again. See Dkt. 561 at 9 (quoting Dkt. 559 at
    1-2); see also Dkt. 509 at 1 n.1 (“The essential witnesses in this case are outside the subpoena
    power of the United States, and multiple witnesses have expressed growing reluctance to testify
    as this matter has dragged on.”); Dkt. 594-1 at 1 (Bonte Decl. 7 2) (“I am not willing to travel to
    Washington D.C. and testify if this trial is postponed again. Either I will testify as scheduled in
    May, or I will not testify.”).
    Moreover, unlike in Yates, there is also a strong, case-specific public policy reason why
    Trabelsi could not have been transported to France for a face-to-face confrontation with Ms.
    Amal during the Rule 15 deposition. Although “the officer who has custody of [a] defendant”
    must, as a general matter, “produce the defendant at [a Rule 15] deposition and keep the
    defendant in the witness’s presence during the examination,” Fed. R. Crim. P. 15(c)(1), a
    deposition “of a witness who is outside the United States may be taken without the defendant’s
    presence if the court makes” a series of “case-specific findings,” including that “the [in-custody]
    35
    defendant cannot be present because . . . secure transportation and continuing custody cannot be
    assured at the witness’s location” and that the defendant “can meaningfully participate in the
    deposition through reasonable means,” Fed. R. Crim. P. 15(c)(3)(D)(E). As the Court
    explained in making these findings under Fed. R. Crim P. 15(c)(3) in its prior memorandum
    opinion and order, Dkt. 578 at 8-10, the Chief of the Office of International Operations in the
    United States Marshals Service submitted a declaration attesting that his “office has determined
    [that] it cannot safely and securely arrange for . . . Trabelsi to travel to Europe,” Dkt. 526-1 at |
    (Panepinto Decl. { 2)—at least in part because “[t]he United States Marshals Service does not
    have authority to maintain custody of a prisoner in a foreign country,” 
    id.
     (Panepinto Decl. 3),
    and because “Trabelsi is subject to Special Administrative Measures (SAMs), which would be
    impossible for the U.S. Marshals to enforce while . . . Trabelsi is within a European country,” id.
    at 2 (Panepinto Decl. 7); see also United States v. McKeeve, 
    131 F.3d 1
    , 7 (1st Cir. 1997)
    (“[T]he U.S. Marshals Service lacks jurisdiction to retain custody of federal detainees on foreign
    soil. ...”). Panepinto further attested to the unsurprising propositions that “it is very likely that
    a European government would not permit. . . Trabelsi to enter their country .. . , especially
    while he is not in custody,” Dkt. 526-1 at 1 (Panepinto Decl. § 3), and that, because of the
    “heightened safety concerns” related to Trabelsi, “no commercial airline is likely to accept [him]
    as a passenger on one of their aircraft,” id. at 2 (Panepinto Decl. § 6).
    Considering this declaration and the other relevant evidence, the Court is persuaded that a
    strong “public interest” precludes providing Trabelsi with a face-to-face confrontation with Ms.
    Amal in France. Given the serious accusations against Trabelsi and the nature of the charges
    against him, including the allegation that he conspired to kill U.S. citizens in Europe, see Dkt. 6
    (Superseding Indictment), the Court finds that there is a compelling national-security interest in
    36
    ensuring that Trabelsi remain in the custody of the U.S. government and remain subject to the
    SAMs, neither of which would be possible if he were brought to Europe for a deposition or for
    remote trial testimony. See, e.g., Medjuck, 
    156 F.3d at 920
     (concluding that, where the
    government “demonstrat[ed] . . . the impossibility of obtaining [the defendant’s] physical
    presence on terms acceptable to the Government” at a Rule 15 deposition, admission of the
    deposition did not violate the Confrontation Clause); United States v. West, No. 08-cr-669, 
    2010 WL 3324886
    , at *4 (N.D. Ill. Aug. 18, 2010) (concluding that a video deposition taken without
    the defendants’ physical presence was admissible where transporting the defendants to the
    deposition would require either “releas[ing] [them] into a war zone” or “turn[ing] [custody] over
    to the Afghan authorities because the United States Marshal’s Service would be unable to keep
    them in custody in Afghanistan”). The Court further finds that it is extremely unlikely that
    France would have allowed Trabelsi to enter the country to cross-examine Ms. Amal,
    particularly if he was not in custody. See McKeeve, 
    131 F.3d at 8
     (“In cases where actions by, or
    the laws of, a foreign nation effectively preclude the defendant’s presence [at a Rule 15
    deposition], furnishing the defendant with the capability for live monitoring of the deposition, as
    well as a separate (private) telephone line for consultation with counsel, usually will satisfy the
    demands of the Confrontation Clause.”). In short, there was no way, consistent with national
    security, to bring Trabelsi to France to confront Ms. Amal in person there.
    Because Ms. Amal is beyond the subpoena power and emphatically refuses to travel to
    the United States—and because, unlike in Yates, there were ample national-security reasons not
    to produce Trabelsi at a deposition in France—denying Trabelsi a face-to-face confrontation with
    Ms. Amal at the Rule 15 deposition (or trial) was, indeed, “necessary to further an important
    public policy,” Craig, 
    497 U.S. at 850
    , that is “more substantial than [the interest in] convicting
    37
    someone of a criminal offense,” Abu Ali, 
    528 F.3d at 241
    . It is also relevant that, as in Abu Ali,
    this is a case in which the government faces unique and formidable obstacles to obtaining
    eyewitness testimony in the courtroom. Given the “global dimension” of terrorism cases, “flatly
    prohibit[ing]” the deposition of foreign witnesses “anywhere but in the United States ... would
    jeopardize the government’s ability to prosecute [those accused of] terror[ism] using the
    domestic criminal justice system.” Jd.; cf Owens v. Republic of Sudan, 
    864 F.3d 751
    , 785 (D.C.
    Cir. 2017) (explaining that in “terrorism cases” under the Foreign Sovereign Immunities Act,
    “firsthand evidence and eyewitness testimony is difficult or impossible to obtain from an absent
    and likely hostile sovereign”). This is not to say that, in every case involving allegations of
    international terrorism, using video testimony is permissible. But the public policy rationales are
    more than sufficient here, where the government has gone to extraordinary lengths to obtain live
    testimony in the courtroom, where Ms. Amal is uniquely situated to provide an eyewitness
    account of certain key events, and where the deposition was conducted in a manner designed, so
    far as possible, to maximize Trabelsi’s confrontation rights.
    b. Indicia of Reliability
    Having resolved Trabelsi’s threshold challenge to the admissibility of the video
    testimony, the Court turns, next, to the more specific question of whether the “other elements of
    confrontation” were guaranteed—in other words, whether Ms. Amal testified under oath,
    whether Trabelsi had a “full opportunity for contemporaneous cross-examination,” and whether
    the jury will be able to view “the demeanor (and body) of the witness as . . . she testifies” so as to
    “adequately ensure[] that the testimony is both reliable and subject to rigorous adversarial testing
    in a manner functionally equivalent to that accorded live, in-person testimony.” Craig, 
    497 U.S. at 851
    ; cf Crawford, 
    541 U.S. at 57
     (describing cross-examination as the “single safeguard” that
    38
    “the Confrontation Clause demands”); Medjuck, 
    156 F.3d at 920
     (finding essential that the
    defendant could, at a Rule 15 deposition, “cross-examine the deposed witness[]’).
    Trabelsi does not contest that Ms. Amal testified under oath at the deposition® or that the
    video technology platform allowed him to see Ms. Amal in real time, to “listen to the
    proceedings as they occurred,” see United States v. Gifford, 
    892 F.2d 263
    , 265 (3d Cir. 1989),
    and, if introduced, would offer the jury the opportunity to view the witness’s “demeanor” and
    (part of) her “body ... as... she testifies,” ° Craig, 
    497 U.S. at 851
    ; see also Abu Khatallah, 282
    F. Supp. 3d at 283 (noting, in deciding that the defendant had an effective opportunity to cross-
    examine a witness in a Rule 15 deposition, that the witness “testified under oath,” the defendant
    “could view the proceedings and communicate with his counsel abroad,” and that the deposition
    was videotaped to allow the jury “a full, visual impression of [the witness’s] responses on cross-
    examination”). Similarly, Ms. Amal was able to see Trabelsi during the deposition—that is, she
    had to face him when he asked and she answered his questions. Nor does Trabelsi contend that
    he had any difficulty communicating with his standby counsel—who were present with him in
    the courtroom and with the witness in France—during the deposition. See Gifford, 892 F.2d at
    8 Notably, and as described in this Court’s prior opinion on the Rule 15 deposition, Dkt. 578 at
    12, the U.S. perjury statute expressly applies extraterritorially, see 
    18 U.S.C. § 1623
    (b), and the
    government represents—without objection or dispute from the defense—that “French law
    criminalizing perjury” will also apply. Dkt. 546 at 1-2 (citing Code Pénal (Penal Code), Art.
    434-13 (https://www.legifrance.gouv.fr/ codes/article_lc/LEGIART10000064 18637 (Translation:
    https://cjad.nottingham.ac.uk/documents/implementations/pdf/France_Penal_Code.pdf)).
    ® Trabelsi does object, briefly, that playing the deposition for the jury would “leav[e] the jury
    with [the] false impression” that “Ms. Amal appeared by herself for questioning”—presumably
    because only her image is visible on the video recording of the deposition. Dkt. 590 at 12. Any
    such misimpression, however, can be easily cured by playing for the jury Ms. Amal’s testimony
    on cross-examination that she is “not alone in the room.” Apr. 26, 2023 p.m. Dep. (Tr. at 46).
    She elaborated: “There’s a commander; there’s the French police; someone from the FBI; an
    interpreter; Mr. Trabelsi; a social worker; and other people I don’t know much about. So I’m not
    alone in the room.” Jd.
    39
    265 (concluding that the defendant’s “right to a fair trial was not violated by the use of . . .
    deposition testimony” where the “[d]efendant was able to listen to the proceedings as they
    occurred[] and was afforded the opportunity to consult with his attorney”). Trabelsi’s central
    objection to the admission of Ms. Amal’s testimony, then, is not to the mechanics of the
    deposition. His principal argument is, rather, that he was afforded insufficient time at the
    deposition “to conduct a meaningful examination of Ms. Amal, a fatal flaw that was,” in the
    defense’s view, “compounded by the improper actions of the government, the French
    government, and Ms. Amal.” Dkt. 590 at 13.
    i. Confrontation Clause standard
    The Confrontation Clause does not afford a defendant unlimited cross-examination.
    Rather, it “guarantees an opportunity for effective cross-examination, not cross-examination that
    is effective in whatever way, and to whatever extent, the defense might wish.” Fensterer, 
    474 U.S. at 20
     (emphasis in original); see also Crawford, 
    541 U.S. at 61
     (explaining that the
    Confrontation Clause is a “procedural . . . guarantee,” and not a substantive guarantee ensuring
    the reliability of testimonial evidence admitted against a defendant). Trial judges, moreover,
    “retain wide latitude insofar as the Confrontation Clause is concerned to impose reasonable
    limits on such cross-examination based on concerns about, among other things, harassment,
    prejudice, confusion of the issues, the witness’ safety, or interrogation that is repetitive or only
    marginally relevant.” Delaware v. Van Arsdall, 
    475 U.S. 673
    , 679 (1986); see also United States
    v. Miller, 
    738 F.3d 361
    , 375 (D.C. Cir. 2013) (same); United States v. Hayes, 
    369 F.3d 564
    , 566
    (D.C. Cir. 2004) (explaining that the Court may reasonably limit “questions on cross-
    examination [that] go beyond the scope of the direct, deal with matters at the fringe of the case,
    40
    are repetitive, confuse the issues, harass the witness, or invite the jury to consider extraneous
    matters”).
    The Confrontation Clause is violated, then, when a defendant is deprived, by a time limit
    or otherwise, of the “opportunity for effective cross-examination” or “when the court bars a
    legitimate line of inquiry that might have given the jury a significantly different impression of
    [the witness’s] credibility.” Miller, 
    738 F.3d at 375
     (internal quotation marks omitted) (quoting
    Hayes, 
    369 F.3d at 566
    ); see also United States v. Berrios-Bonilla, 
    822 F.3d 25
    , 31 (1st Cir.
    2016) (explaining that the Court first reviews “de novo to determine whether [the] defendant was
    afforded a reasonable opportunity to impeach adverse witnesses’ consistent with the
    Confrontation Clause” and then, “[i]f that threshold is met,” reviews “the specific limitation
    imposed by the trial court on the defendant’s cross-examination for abuse of discretion” (internal
    quotation marks omitted) (emphasis omitted) (first alteration in original)). The “opportunity” for
    effective cross-examination includes a reasonable opportunity to elicit “impeaching or
    discrediting testimony,” United States v. Hart, 
    995 F.3d 584
    , 589 (7th Cir. 2021) (explaining that
    “any constitutional concerns vanish” once the defendant has been given that opportunity), or to
    “provid[e] the jury with essential information about key events and sufficient information to
    make a ‘discriminating appraisal’ of a witness’s motives and possible bias,” United States v.
    Malik, 
    928 F.2d 17
    , 20 (1st Cir. 1991); see also McPherson v. Woods, 
    506 F. App’x 379
    , 390
    (6th Cir. 2012) (concluding that the Sixth Amendment was satisfied where the defendant “was
    given adequate opportunity to explore [the witness’s] conflicting statements, her credibility, and
    her observations on the day of the shooting”); United States v. Spangler, 
    638 F. App’x 611
    , 613
    (9th Cir. 2016) (noting that defense counsel “was able to question [the witness] about matters of
    4]
    bias” and that it could, accordingly, “[]not be said that the jury lacked sufficient information to
    appraise the biases and motivations of [the witness]” (internal quotation marks omitted)).
    ii. Trabelsi's opportunity for cross-examination
    Trabelsi was provided a reasonable opportunity to “impeach [Ms. Amal’s] credibility and
    establish that she ha[d] a motive to lie.” United States v. Clark, 
    657 F.3d 578
    , 583-84 (7th Cir.
    2011). In total, the government represents—and the defense does not contest—that Trabelsi’s
    cross-examination of Ms. Amal lasted more than seven hours, “compared against the
    government’s direct examination that took less than three hours.” Dkt. 588 at 2. The Court
    estimates, moreover, that the government’s direct examination occupied roughly 67 pages of the
    deposition transcript, see Apr. 26, 2023 a.m. Dep. (Tr. at 11-43); Apr. 26, 2023 p.m. Dep. (Tr. at
    4-35), while Trabelsi’s cross-examination occupied about 184 pages of the transcript, see Apr.
    26, 2023 p.m. Dep. (Tr. at 44-70); Apr. 27, 2023 a.m. Dep. (Tr. at 9-82); Apr. 27, 2023 p.m.
    Dep. (8-49, 53-59, 63-91) (omitting time spent on the government’s motion to end the
    deposition). To be sure, neither the length of Trabelsi’s examination nor the comparison
    between the government’s direct examination and his cross-examination—standing alone—
    answer the question of whether Trabelsi had an adequate opportunity to cross-examine the
    witness. But these facts do provide a helpful starting point. Most significantly, the proper scope
    of the cross-examination was limited by the scope of the direct, which was short and focused.
    Moreover, even with the necessary translation process, over seven hours of examination is
    substantial. In United States v. Abu Khatallah, 
    282 F. Supp. 3d 279
     (D.D.C. 2017), by way of
    comparison, the court concluded that the “timing and circumstances” of a Rule 15 deposition
    “gave the defense ample opportunity to conduct a vigorous cross-examination” where “[c]ross-
    examination lasted approximately three hours and covered a wide range of topics.” Jd. at 283.
    42
    Similarly, in United States v. Vest, 
    116 F.3d 1179
     (7th Cir. 1997), the Seventh Circuit
    determined that the defense had “the ‘reasonable chance’ to pursue matters covered on direct that
    the Confrontation Clause protects” where the defense counsel had “seven hours and twenty
    minutes” to cross-examine an expert witness, and where “the Government used less than two
    hours on direct.” Jd. at 1187; see also 
    id.
     (noting approvingly that “[t]he District Court’s time
    limits were reasonably anchored to . . . the amount of time the Government used on direct”); see
    also Fenenbock v. Dir. of Corr., 
    692 F.3d 910
    , 920 (9th Cir. 2012) (“Petitioner presents no
    cogent explanation as to why the time used by his defense counsel at trial (about three hours)
    plus the unused four hours offered by the trial court would not have sufficed to explore the
    intended material exhaustively.”). And in United States v. Smith, 
    928 F.3d 1215
     (11th Cir.
    2019), the Eleventh Circuit observed, albeit with the apparent agreement of the parties, that
    defense counsel had “tested [the witness’s] testimony and credibility with sufficient cross-
    examination” during a Rule 15 deposition where “the government’s direct and redirect
    examination of [the witness] total[led] approximately 32 pages, [and] the cross-examination by
    defense counsel, together, total[led] 79 pages of the deposition transcript.” Jd. at 1227.
    More importantly, after studying the transcript in detail, the Court is persuaded that
    Trabelsi was given sufficient opportunity, had he used his time wisely, to explore Ms. Amal’s
    credibility and the veracity of her testimony on direct. Indeed, during his seven hours of cross-
    examination, Trabelsi explored some lines of questioning that were relevant to Ms. Amal’s
    “biases and motivations.” Spangler, 638 Fed. Appx. at 613. He asked, for example, whether
    Ms. Amal “fe[It] under pressure or threatened by someone in France,” Apr. 26, 2023 p.m. Dep.
    (Tr. at 47), and whether “members of the U.S. government or the French government . . .
    threaten[ed] [her] [that] if [she] did not testify against [him], [she] would be charged with a
    43
    crime,” Apr. 27, 2023 p.m. Dep. (Tr. at 56). He asked her whether she “received money from
    the U.S. government related to [this] case,” id. at 63,!° and whether she received French
    citizenship in exchange for testifying against him, id. at 72; see also id. at 86 (“[I]s it time or is it
    money or the French citizenship that led you to tell the authorities what they wanted to hear?”). |!
    Afier his questions elicited Ms. Amal’s account that Trabelsi had violently abused her, see Apr.
    26, 2023 p.m. Dep. (Tr. at 64),!* Trabelsi confronted the witness with letters she sent him after
    his arrest, in which she apparently expressed her love and affection for him, see, e.g., Apr. 27,
    2023 p.m. Dep. (Tr. at 40) (“You started from the beginning by saying: I love you, I love you, I
    love you until the last day of my life.”); see also Apr. 26, 2023 p.m. Dep. (Tr. at 66). And,
    '° The defense notes that, in response to this question, Ms. Amal denied receiving anything of
    value from the United States related to the prosecution of Trabelsi, Apr. 27, 2023 p.m. Dep. (Tr.
    at 63-64, 66), and attaches to its motion an exhibit indicating that Ms. Amal was paid $2,000.00
    by the FBI in 2005, see Dkt. 590-1. But, based on the deposition transcript, it appears that both
    Trabelsi and the witness had this exhibit in front of them at the time Trabelsi asked about the
    payment, and he could have asked the witness to review the document with the assistance of the
    interpreter. See Apr. 27, 2023 p.m. Dep. (Tr. at 63) (Trabelsi stating: “Exhibit 110, please.”); id.
    (From the witness: “I have a document in front of me, but it’s in English, so I didn’t understand
    what it was.”).
    '' The defense also notes that, while a question relating to such benefits was pending, “Ms. Amal
    spoke with a French Official who was present in the room and seated across from her.” Dkt. 590
    at 7. Judge Upadhyaya noticed the same at the time and asked Ms. Amal, “for clarity of the
    record, what the discussion was about with the person who was sitting across from her?” Apr.
    27, 2023 p.m. Dep. (Tr. at 69). Ms. Amal answered that “they were explaining to me how to use
    the microphone switches properly, how to unmute myself.” Jd. Although defense counsel—who
    was standby counsel at the time—interjected that “[t]hat’s not true,” id. at 70, counsel has, to
    date, never proffered to the Court or to the government what, in counsel’s view, the discussion
    with the French prosecutor entailed. See Dkt. 593 at 7 n.8 (representing that defense counsel has
    not responded to the government’s request to “proffer what [she] heard the witness say during
    the few seconds that she was muted”). Nor has defense counsel submitted any evidence to
    contradict the witness’s testimony that the discussion concerned a mute button.
    '2 Many of the statements Trabelsi elicited about his alleged abuse have been struck, at the
    defense’s request, Dkt. 618, before this testimony will be introduced into evidence. In resolving
    the parties’ evidentiary objections to various questions and answers, counsel for the defense has
    candidly conceded that at least some of Trabelsi’s questions were unwise and unhelpful.
    44
    perhaps most importantly, Trabelsi elicited, multiple times, that Ms. Amal’s rendition of the
    relevant events changed between her initial interviews with the French authorities in 2001 and
    her later testimony before the U.S. grand jury in 2007, see, e.g., Apr. 27, 2023 p.m. Dep. (Tr. at
    85); id. at 88 (reading from the 2001 interview transcript in which the witness told authorities
    that “[they] went to Afghanistan to help poor people”). For example:
    Q. Ms. Amal, I have to ask a first question about all your testimony since your
    arrest on September 15th, 2001, all the way to your last statement in France
    to the French authorities. You swore to tell the truth, but is it true that you
    lied and you didn’t tell the truth?
    [A.] Yes, it’s true that at the beginning I was very, very scared and I did lie. But
    after, I promised to tell the truth, and I did tell nothing but the truth.
    Apr. 26, 2023 p.m. Dep. (Tr. at 52).
    That Court does not doubt that Trabelsi might have done more to attempt to impeach Ms.
    Amal or to explore the sources of any biases. But the operative legal question is not whether
    Trabelsi did, in fact, expose any inconsistencies or biases or otherwise undermined her testimony
    on direct; it is, rather, whether he had the reasonable opportunity to do so. See Fensterer, 
    474 U.S. at 20
    . The answer to that question is “yes”—he had ample opportunity to explore additional
    areas of impeachment during his lengthy cross-examination. But instead of doing so, he devoted
    most of his time to questions that were of marginal relevance, at best; that were way beyond the
    scope of the direct; and that were often argumentative, harassing, or lengthy exhortations on his
    view of the facts and evidence. Among other topics, he explored the wellbeing of Ms. Amal’s
    children, see Apr. 26, 2023 p.m. Dep. (Tr. at 44, 48-49); discussed at length (and repeatedly) the
    question of whether he was in a religious marriage with Ms. Amal, see, e.g., Apr. 27, 2023 a.m.
    Dep. (Tr. at 11-14); Apr. 27, 2023 p.m. Dep. (Tr. at 30-31); and queried Ms. Amal again and
    again about the legal status of her prior romantic relationships, Apr. 27, 2023 a.m. Dep. (Tr. at
    45
    30, 38, 45). Based on the record before the Court, it is unclear what relevance Ms. Amal’s prior
    romantic relationships—much less the current well-being of her children—have to Trabelsi’s
    defense. To be sure, earlier in the litigation, the marriage-related questions might have been
    relevant to Trabelsi’s motion to preclude privileged marital communications, Dkt. 511, but the
    Court had denied that motion in an oral ruling before the deposition began. See Apr. 25, 2023
    Hrg. Tr. (Rough at 10). In that ruling, the Court explained that “the most relevant jurisdiction for
    purposes of determining whether there was a valid marriage” was Germany and that a religious
    ceremony, standing alone, was insufficient to establish a marriage “as a matter of German law.”
    Id. at 11-12. Trabelsi’s repeated questions about a religious marriage ceremony between himself
    and Ms. Amal were, accordingly, irrelevant to the application of the marital communication
    privilege. To the extent the existence (or not) of a purely religious marriage is relevant to
    Trabelsi’s defense, his theory is far from evident and, in any event, cannot possibly have justified
    the enormous amount of time that Trabelsi devoted to the topic.
    Many of Trabelsi’s questions also veered into personal attacks that the witness could
    reasonably have perceived as harassing and that were, at a minimum, argumentative: “Is it
    because you are pregnant that you think you have the right to swear to God and then to lie to hurt
    other people to protect yourself?” Apr. 26, 2023 p.m. Dep. (Tr. at 55). And the next day: “Mrs.
    Amal, I am a human being, and I was married with you, you are my son’s mother and you swore
    to God to tell the truth. ... So I want to ask you again to pay special attention, because I don’t
    want you to have problems.” Apr. 27, 2023 a.m. Dep. (Tr. at 30). “[S]ince I’ve met you... all
    my life has changed,” Trabelsi stated. Jd. at 13-14. Later that morning: “Were you a jealous
    woman?” Jd. at 64. And that afternoon: “Do you realize that... and you have God as a
    witness—that you committed adultery because you had a child with me out of wedlock?” Apr.
    46
    27, 2023 p.m. Dep. (Tr. at 79). Trabelsi used his time for cross-examination, moreover, to
    essentially testify at length, telling winding stories about Ms. Amal’s visits while Trabelsi was in
    prison and about interactions between the two at the beginning of their romantic relationship.
    See, e.g., Apr. 26, 2023 p.m. Dep. (Tr. at 68-70); Apr. 27, 2023 p.m. Dep. (Tr. at 9-12).
    Trabelsi was representing himself at the deposition, and it was up to him to decide how to
    use his time. But he cannot—after having spent most of his cross-examination time on
    repetitive, marginally relevant, and (at times) harassing questions—claim that he was deprived of
    the opportunity to do more. See, e.g., United States v. Pugh, 
    436 F.2d 222
    , 224 (D.C. Cir. 1970)
    (“[I]f cross-examination of a witness has been extensive, repetitive and protracted, . . . the trial
    judge might properly limit the scope of cross-examination without in any way harming
    defendant’s case.”); United States v. Stock, 
    948 F.2d 1299
    , 1302 (D.C. Cir. 1991) (same); see
    also United States v. Walker, 
    917 F.3d 1004
    , 1010 (8th Cir. 2019) (affirming the district court’s
    time limitation where “most of the cross-examination had been spent cumulatively reading an
    exhibit . . . that had been admitted into evidence and would be available to the jury”). It is true,
    of course, that Ms. Amal is an important witness, that her testimony covers, as the defense
    asserts, a broad “variety of events and issues,” and that the flow of cross-examination was
    slowed down, to some extent, by the fact that each question and answer was translated for the
    record from French to English (and, for the witness, back from English to French again). Dkt.
    590 at 5-6. But Trabelsi has failed to show that the seven hours of cross-examination afforded to
    him (even with the encumbrance of translation) did not provide him with the opportunity to
    explore Ms. Amal’s “conflicting statements, her credibility, and [the limited] observations” she
    testified about on her three-hour direct examination (which was itself slowed down, to some
    extent, by English-to-French translation). McPherson, 506 F. App’x at 390; see also Hart, 995
    47
    F.3d at 589 (“[A]n opportunity [to cross-examine] is reasonable if the defendant merely ha[s] the
    chance to present a motive to lie.” (internal quotation marks omitted)). To be sure, Trabelsi
    squandered much of this opportunity, but had he spent the hours that he devoted to irrelevant,
    marginally relevant, argumentative, and otherwise improper questions on substantive matters, he
    would have had ample opportunity to conduct a constitutionally sufficient cross-examination.
    See Vest, 
    116 F.3d at 1186
     (Where “the District Court . . . set a time limitation on cross-
    examination . . . during [which the defendant] had every opportunity to cover” the issues raised
    on direct, his “failure to address matters raised on direct might . . . be attributed to [his] poor time
    management during cross-examination.”). Although standby counsel asserted during the
    deposition that “even a lawyer would be hard-pressed to do this cross-examination in six hours,”
    Apr. 27, 2023 p.m. Dep. (Tr. at 61), defense counsel has neither raised that argument in its filings
    nor endeavored to explain why—by reference to possible cross-examination topics or
    otherwise—seven hours would have been insufficient for a capable lawyer to “provid[e] the jury
    with essential information about key events and sufficient information to make a ‘discriminating
    appraisal’ of [this] witness’s motives and possible bias.” Malik, 
    928 F.2d at 20
    .
    ili. Trabelsi’s pro se status
    Trabelsi argues that the length of his cross-examination was nevertheless insufficient
    because he was “proceeding pro se” and because he “ha[d] been imprisoned for ten years under
    extremely harsh conditions of confinement that ha[d] negatively affected his mental state and
    ability to concentrate and focus on his questions and her answers.” Dkt. 590 at 6. It is true, of
    course, that a capable lawyer might have more effectively and efficiently cross-examined Ms.
    Amal and that this Court has, in the past, given Trabelsi “some leeway because he is representing
    himself.” See, e.g., Dkt. 578 at 13-14. But it is also true that Trabelsi cannot deprive the
    48
    government of a key witness, who is beyond the subpoena power of this Court, by electing to
    represent himself and then asserting a need for additional time (which was unavailable) as a
    result.
    The Court warned Trabelsi at his Faretta hearing that he would “be better off with a
    trained lawyer,” that learning and following the rules of evidence would be “complicated,” and
    that the Court would not rule in his favor “just because [he was] representing [him]self.” July 8,
    2022 Hrg. Tr. (Rough at 20-21, 25). Trabelsi nevertheless insisted on cross-examining Ms.
    Amal himself, even after the Court offered two days before the deposition that, “subject to the
    government’s consent, [the Court] would not have an objection to standby counsel
    ... conducting the cross-examination of Ms. Amal on Wednesday and Thursday” in Trabelsi’s
    place. Apr. 24, 2023 Hrg. Tr. (Rough at 102). But, Trabelsi’s standby counsel had previously
    explained to the Court that Trabelsi “want[ed] to question this witness as part of his decision to
    represent himself,” Jan. 10, 2023 Hrg. Tr. (Rough at 14), and, consistent with that intention,
    Trabelsi neither accepted this offer nor moved to relinquish his self-representation until after he
    had completed his cross-examination of Ms. Amal, see Dkt. 586. It is evident to the Court that
    Trabelsi wanted to represent himself in significant part so that he could confront—in every sense
    of the word—his former “spouse.” See, e.g., Dkt. 534 at 31 (Mar. 10, 2023 Hrg. Tr.) (“But face-
    to-face . . . how could it be said that I struck her? She loves me to death.”).
    Nor can Trabelsi plausibly assert that he was surprised by the length of the deposition or
    that he would have, if he had known that the deposition would end at 6:00 p.m. (12:00 a.m. Paris
    time) on the second day, managed his time more carefully. Before the deposition began, Trabelsi
    knew that the deposition would, in all likelihood, be limited to two days of questioning: Judge
    Upadhyaya warned, from the outset, that “[bJoth sides should be prepared to conclude their
    49
    questioning of Ms. Amal in the time allotted, by 6 p.m. EST on Thursday, April 27, 2023.” Dkt.
    579 at 3. The Court had also previously stressed, after observing Trabelsi’s over-long and
    unfocused cross-examinations during a suppression hearing, that Trabelsi should “limit his
    examination to proper and relevant questions within the scope of the government’s direct
    examination of its witness,” Dkt. 587 at 14, and that, “as a rule of thumb,” Trabelsi would
    typically “have twice the time the government takes with respect to [its] direct examination,”
    unless he “ma[d]e a showing of specific need,” Apr. 19, 2023 Hrg. Tr. (Rough at 4-5). And,
    from the very beginning of the deposition, Judge Upadhyaya warned Trabelsi again and again to
    “ask the important questions,” and not “to waste time.” Apr. 26, 2023 p.m. Dep. (Tr. at 37); see
    also 
    id. at 60
     (reminding Trabelsi “to focus on questions about the case”); Apr. 27, 2023 a.m.
    Dep. (Tr. at 15) (reminding Trabelsi “of [his] time today” and cautioning him to “use it wisely,
    please”); 
    id. at 59
     (“This is your time, so just use it wisely. I’ve said it a million times, I’m going
    to keep reminding you.”); 
    id. at 83
     (“[T]here have been some topics which you have gone into
    over and over and over again .. . keep in mind how much time you have left and ask your
    questions accordingly.”). The Court, moreover, did not apply its rule of thumb about providing
    Trabelsi twice the government’s time in an inflexible manner: when the government did move to
    end the deposition because Trabelsi had “been going for a little over six hours” and had not
    “made effective and efficient use of his time,” Apr. 27, 2023 p.m. Dep. (Tr. at 49-50), the Court
    denied the government’s motion and offered Trabelsi more time to explore the three “buckets” of
    questions identified by his standby counsel, 
    id. at 62-63
    . In short, Trabelsi was given every
    possible warning to make use of his opportunity for effective cross-examination. See Spangler,
    638 F. App’x at 613 (noting, in approving of the district court’s “time limit on defense counsel’s
    cross-examination,” that “the district court gave counsel timely warnings that his cross-
    50
    examination was becoming repetitive, argumentative, and unfocused” and noting that the
    defendant “had fair warning before he was told his examination was complete”).
    In addition to the Court’s warnings and advice to Trabelsi, government counsel made
    efforts to ensure that time Trabelsi would have the opportunity to conduct a sufficient cross-
    examination. They cut their direct examination of Ms. Amal “down . . . to the bare minimum” in
    the interest of allowing Trabelsi sufficient time, Apr. 19, 2023 a.m. Hrg. Tr. (Rough at 4); see
    also Apr. 18, 2023 Hrg. Tr. (Rough at 230), and they gave up the opportunity to conduct a
    redirect examination, even after a lengthy and confusion cross-examination by Trabelsi.
    Notwithstanding these warnings and accommodations, Trabelsi chose to conduct the cross-
    examination himself (rather than asking standby counsel to do so), and he squandered much of
    the seven hours he was allotted.
    Even when a pro se defendant “conduct[s] his own defense ultimately to his own
    detriment,” Faretta v. California, 
    422 U.S. 806
    , 834 (1975)—as Trabelsi did in this case—the
    Court must “honor[] his choice by abstaining from interfering with his right to self-
    representation,” United States v. Curry, 
    575 F. App’x 143
    , 146 (4th Cir. 2014). Although the
    Court granted Trabelsi substantial leeway where possible in light of his pro se status (including,
    for example, in ruling liberally on objections as to the form of specific questions or in allowing
    his tortuous examination of two witnesses at a suppression hearing), that leeway cannot extend
    so far that it alone deprives the government of the ability to present the testimony of a key
    witness.
    iv. Deposition delays
    To be sure, the deposition, as a whole, was slightly shorter than initially anticipated by
    the parties and the Court. The parties devote significant attention in their briefs to finger-
    51
    pointing about who is responsible for these delays. The defense, for example, accuses
    government counsel of being “late and unprepared to proceed on time on April 26 and 27,”
    causing the deposition to begin later than anticipated. Dkt. 590 at 3. The government, in
    response, credibly and quite reasonably explains that “AUSA Saunders was ready and outside
    the locked courtroom by 8:15am” on April 26, 2023, but that “it took longer than expected to set
    up all the equipment once the courtroom was opened” and to “ensure that everything ...
    functioned properly.” Dkt. 593 at 5 n.2. The government also explains that, on April 27, 2023,
    there was a short delay “primarily because of a technology issue in France.” Jd. Delays
    resulting from minor technical difficulties are unexceptional in any case and are to be expected
    in a case, such as this one, involving a transatlantic deposition. The Court, moreover, has no
    reason to believe that the government had any interest in limiting the length of the deposition; to
    the contrary, it had every incentive to provide Trabelsi with as much time for cross-examination
    as was possible under the circumstances, especially in light of the Court’s repeatedly warnings
    that the deposition would not be admitted if Trabelsi was not given “a meaningful opportunity to
    conduct an adequate cross-examination.” Dkt. 578 at 13.'3
    '3 The government argues that Trabelsi, in contrast, was well aware that a curtailed cross-
    examination would make it more difficult for the government to introduce the deposition at trial
    and that he, accordingly, had an incentive to delay the deposition where possible. In that vein,
    the government notes, for example, that Trabelsi took three restroom breaks during the
    government’s three-hour direct examination—which occupied, in total, 50 minutes of break
    time—but that he never asked for a restroom break during his own examination of the witness.
    Dkt. 593 at 5 n.4. (The Court, for its part, has no reason to doubt Trabelsi’s explanation that the
    bathroom breaks were related to a medical issue, which Trabelsi had previously brought to the
    Court’s attention.). The government also asserts that, “{d]uring one break, standby counsel told
    the witness she could simply leave the deposition and come back on Friday,” notwithstanding the
    fact that “[n]o arrangements were in place for the deposition to continue on Friday.” Dkt. 593 at
    6 n.5; see also May 11, 2023 Hrg. Tr. (Rough at 23) (statement from government counsel present
    in France that “[standby counsel] started to address the witness” during a break on April 26,
    2023 and that standby counsel told the witness “it would be appropriate for the witness to leave,
    52
    More significantly, the defense asserts that the French authorities “unilaterally seized
    authority and control of the deposition from Magistrate Judge Upadhyaya” by summarily ending
    the deposition at 4:40 p.m. on April 26, 2023—one hour and twenty minutes before the
    anticipated end time of 6:00 p.m. that day. Dkt. 590 at 3-4. In response, the government
    contends that it was Trabelsi’s standby counsel—who was present at the deposition in France—
    that announced, without corroboration, that the French officials were summarily ending the
    deposition for the day. Dkt. 593 at 5 (arguing that “[s]tandby Counsel . . . ended the deposition
    early on Wednesday, reporting that ‘the French prosecutor says they’re done for the day,’ even
    though no French official in the room had spoken”); see Apr. 26, 2023 p.m. Dep. (Tr. at 70)
    (“[T]he French prosecutor says they’re done for the day.”). But, even if defense counsel’s
    assertion as to the French government were credited—and there is conflicting evidence on this
    point!4—neither Mr. Trabelsi nor his standby counsel objected to ending the deposition at 4:40
    that she could end for the day if she wanted to[,] and that we could come back on Friday”).
    Standby counsel responded that she did not “recall what [she] said,” that she “recall[ed] feeling
    sympathetic or suggesting a longer break or something,” but that she “d[idn’t] think [she]
    addressed the witness.” May 11, 2023 Hrg. Tr. (Rough at 28). The Court need not resolve this
    dispute for present purposes.
    '4 The record reflects that, earlier in the day, the French authorities told government counsel that
    “they need[ed] to stop at 22:00 their time” (i.e., 4:00 p.m. EST). Apr. 26, 2023 p.m. Dep. (Tr. at
    50). But there is no indication in the deposition transcript, other than standby counsel’s
    statement that “the French prosecutor says they’re done for the day,” 
    id. at 70
    , that the French
    authorities followed through on their stated intention to end the deposition earlier than
    anticipated. See, e.g., May 11, 2023 Hrg. Tr. (Rough at 22) (statement from government counsel
    explaining that they had asked the French authorities over text to “please, please keep going” and
    that, “when [10:00 p.m.] passed and they didn’t cut it off, we were hoping it was going to keep
    going”); 
    id. at 25
     (“[W]e got to 10:00 p.m. and they did not raise the issue again.”). Standby
    counsel’s account of what occurred, moreover, is subject to reasonable dispute. Most notably,
    she has given the Court conflicting accounts of what prompted her statement that “the French
    prosecutor says they’re done for the day.” Apr. 26, 2023 p.m. Dep. (Tr. at 70). Standby counsel
    represented, first, that the French prosecutor made a “gesture of being done,” relaying the
    impression that she was ending the deposition. May 10, 2023 Hrg. Tr. (Rough at 67) (although
    not reflected in the record, standby counsel demonstrated what she meant by this by making a
    53
    p.m. on April 26, 2023. Had an objection been raised at the time, the Court could have
    endeavored to enforce the agreement to continue to 6:00 p.m. Ultimately, however, none of this
    back-and-forth between the parties is dispositive because the Court is persuaded that, even with
    these delays, Trabelsi had sufficient time to conduct a reasonable cross-examination of Ms.
    Amal.
    v. Proffered topics for further exploration
    Nor has Trabelsi established that, by ending the cross-examination as scheduled at 6:00
    p.m. on April 27, 2023, the Court effectively “bar[red] a legitimate line of inquiry that ‘might’
    have given the jury a ‘significantly different impression of [the witness’s] credibility.’” Miller,
    
    738 F.3d at 375
     (quoting Hayes, 
    369 F.3d at 566
    ); see also, e.g., Harrington v. Iowa, 
    109 F.3d 1275
    , 1277 (8th Cir. 1997) (requiring a defendant to show that “[a] reasonable jury might have
    received a significantly different impression of [the witness’s] credibility had [defense] counsel
    been permitted to pursue his proposed line of cross-examination” (quoting Van Arsdail, 
    475 U.S. at 680
    )); United States v. Bunchuk, 
    799 F. App’x 100
    , 105 (3d Cir. 2019) (concluding, where
    “the trial court gave [the defendant] ample leeway to cross examine the Government’s
    witnesses,” that the trial court “properly denied [the defendant] the opportunity to present other
    testimony that would be irrelevant or redundant”). The Court addresses this question by
    reference to the specific lines of questioning proffered by the defense; any proposed questions
    not raised, at this stage, have been forfeited. See United States v. Davis, 
    127 F.3d 68
    , 71 (D.C.
    hand gesture across her throat). The next day, standby counsel indicated that, “[a]s it came close
    to the time [of ending the deposition],” she recalled the French prosecutor “packing up” her
    work, May 11, 2023 Hrg. Tr. (Rough at 29), and she later amended her account yet again,
    asserting that the French prosecutor said something out loud about ending the deposition, id. at
    31-32 (“I said the words, the French prosecutor said.”), even though the record of the deposition
    reflects no such statement and none of the government personnel who were present saw or heard
    any of these things.
    54
    Cir. 1997) (citing United States v. Martinez, 
    776 F.2d 1481
    , 1485-86 (10th Cir. 1985) for the
    proposition that “the court has no way to determine whether there was an abuse of discretion”
    where the defendant “fail[s] to make a record of what he would have shown on cross-
    examination”); see also Hart, 995 F.3d at 590 n.3 (concluding that a defendant “forfeited [a] line
    of questioning” that he apparently wanted to explore during his cross-examination “by not
    raising it at trial’’).
    The Court has before it two distinct proffers: an oral proffer that Trabelsi himself made
    during a May 3, 2023 motions hearing and a written proffer offered by Trabelsi’s counsel on
    May 5, 2023, see Dkt. 590 at 7—the day after Trabelsi relinquished his right to self-
    representation. Although the two proffers overlap in substantial part, the Court will rely on the
    more focused proffer submitted by Trabelsi’s counsel, who now speaks on his behalf. Nor, in
    any event, is Trabelsi’s proffer particularly helpful because he merely asserted that he would
    have shown that Ms. Amal’s statements were “false,” “lie[s],” or “craziness,” largely without
    providing the Court with a basis to understand how he would have made those showings with
    additional time for cross-examination. See May 3, 2023 Hrg. Tr. (Rough at 4-17).
    The May 5, 2023 proffer asserts that Trabelsi would “seek to cover” fourteen subjects “in
    additional testimony.” Dkt. 590 at 7. Those subjects fall, roughly, into seven buckets: (1) Ms.
    Amal’s prior inconsistent statements about “her lack of knowledge of Mr. Trabelsi’s activities in
    Afghanistan” and “statements about the purpose of their time in Afghanistan;” (2) Ms. Amal’s
    “cooperation in investigations in Europe,” “benefits conferred on Ms. Amal by foreign
    government officials,” and “the current relationship between her and the French security services
    and whether their presence at the deposition intimidated her, or otherwise affected her
    testimony;” (3) “the status of [her] relationship [with Trabelsi] between 2000 and 2002,”
    55
    “statements Ms. Amal made about a religious marriage with Mr. Trabelsi in 2000,” and
    “statements made about Ms. Amal’s prior relationships;” (4) Ms. Amal’s prior “illegal
    conduct... before she met Mr. Trabelsi;” (5) “Ms. Amal’s contact with Mr. Trabelsi after his
    arrest;” (6) “statements about Mr. Trabelsi’s alleged abuse of Ms. Amal;” and (7) “Ms. Amal’s
    availability to travel to the United States for trial.” Jd.
    Some of these topics, to be sure, cover traditional areas of cross-examination that, if
    explored further during cross-examination, might have been helpful to Trabelsi—including, for
    example, Ms. Amal’s prior inconsistent statements and her receipt of any government benefits.
    But the Court cannot conclude, on the basis of this proffer alone, that merely “cover[ing]” these
    broad areas in more detail would be likely to “give[] the jury a significantly different impression
    of [the witness’s] credibility,” Miller, 
    738 F.3d at 375
     (internal quotation marks omitted),
    because Trabelsi did—at least to some extent—address each of these topics in his cross-
    examination. Some of the topics he even covered in expansive form and in great detail: As
    described above, Trabelsi explored at length, and throughout the deposition, the “status” of his
    relationship with Ms. Amal, whether they had a “religious marriage,” and Ms. Amal’s statements
    as to her “prior relationships,” notwithstanding the fact that these topics were (at best) marginally
    relevant to Trabelsi’s case. Dkt. 590 at 7. For example:
    Q. We are going to talk about our marriage. Do you recall that you said yourself
    about me this: “Of this man, I. . . currently expect a child. In regards to the
    Quranic law, I am married to this man. .. . [T]here was a ceremony before
    the imam with two witnesses, two men... .
    A. So yes, I do remember this statement. But however, I was married to you,
    you know very well that you had said that I was married because of the
    Quran. I do remember this. But there was no ceremony. And according to
    Quranic law, yes, we were married. But according to French or German or
    Belgian or any other country’s law, we were not married. You only brought
    to me a piece of paper that said we were married from the imam. And Your
    56
    Honor, this dates back to such a long time ago that I really have no memory
    of this.
    Apr. 27, 2023 a.m. Dep. (Tr. at 11-12). And later that same morning, he asked again:
    Q. I’m asking you again, are you sure that you were never married before Mr.
    George Beyer?
    Q. Mrs. Amal, my question is this: In your mind, in your head, in your soul—
    and I’m thinking about the past, so you have no recollection of being married
    to your cousin, is that your testimony?
    Q. So here’s my question, ma’am: You stated clearly that you’ve never been
    married before marrying Mr. Beyer. So this is really clear, ma’am, that
    you’ ve used this marriage as a mean to an end. And you stated that you were
    not married, however you accused me of hitting you, of raping you. You
    consider me as a human being who does not exist, and all you are doing is
    hurting all of us.
    Id. at 30, 38, 45. Within this line of inquiry, Trabelsi also asked Ms. Amal—albeit briefly—
    about her prior (alleged) “illegal conduct . . . before she met Mr. Trabelsi,” Dkt. 590 at 7,
    including allegations that she was living “illegally in the federal republic [of Germany],” Apr.
    27, 2023 a.m. Dep. (Tr. at 44), and allegations that she failed to pay taxes in Germany, id. at
    28.!°
    Of arguably greater relevance, Trabelsi also addressed on multiple occasions throughout
    the deposition “Ms. Amal’s contact with [him] after his arrest.” Dkt. 590 at 7. See, e.g., Apr. 27,
    2023 p.m. Dep. (Tr. at 40) (“You started from the beginning by saying: I love you, [ love you, I
    love you until the last day of my life.”); see also Apr. 26, 2023 p.m. Dep. (Tr. at 66) (“Did you
    '5 The Court has sustained the government’s objection to Trabelsi’s question regarding Ms.
    Amal’s alleged non-payment of taxes two decades ago as inadmissible under Fed. R. Evid. 403,
    but, giving Trabelsi the benefit of the doubt, overruled the government’s objection to questions
    regarding her immigration status in Germany.

    observe that your name is there [on the letter] and you signed on the second page with kisses and
    the baby and your son; and you said your son said this; and you said you wanted to build a
    family together, and may God hear us; and we’ ll join you after you get out of prison; there is
    your name and your signature there and lots of kisses?”). And, as an apparent corollary to
    Trabelsi’s questions about the love letters Ms. Amal allegedly sent Trabelsi after his arrest,
    Trabelsi asked her several questions about his “alleged abuse of [her],” Dkt. 590 at 7,
    notwithstanding the fact that the government did not bring up such abuse on direct examination.
    As an example:
    Q. Mrs. Amal, do you remember making statements to the FBI in 2005 and to
    the FBI in 2007 and to the grand jury that you were a very unhappy woman,
    and that I was a violent husband who was depriving you of all your rights?
    A. Yes, I remember. I remember that once in Afghanistan, you had hit me
    violently, and also that in Belgium you didn’t let me go out. Do you
    remember that?
    Q. (In English) I never did that.
    Q. So here’s another letter that you sent me to the jail, and you say that I was a
    husband who was violent and that I put a gun to your head.
    Apr. 26, 2023 p.m. Dep. (Tr. at 64-65). Absent explanation of why, exactly, further exploration
    of such abuse allegations would be helpful to Trabelsi, the Court cannot understand how
    “cover[ing]” that topic in further detail would be likely to “give[] the jury a significantly
    different impression of [the witness’s] credibility,” Miller, 
    738 F.3d at 375
     (internal quotation
    marks omitted)—especially because Trabelsi’s counsel has now moved to strike all of Ms.
    Amal’s testimony “regarding any threats made by Mr. Trabelsi against Ms. Amal or others and
    any allegation that Mr. Trabelsi abused Ms. Amal,” Dkt. 618 at 1. Nor has Trabelsi explained
    why asking Ms. Amal more about her availability to travel to the United States for trial would be
    58
    fruitful in light of her testimony on cross-examination that she “cannot come to Washington, to
    the trial, because [she] ha[s] several sick children who need [her] 24 hours a day,” Apr. 27, 2023
    p.m. Dep. (Tr. at 57-58).
    Trabelsi also explored, albeit sporadically and often unskillfully, Ms. Amal’s prior
    inconsistent statements about “her lack of knowledge of Mr. Trabelsi’s activities in Afghanistan”
    and about “the purpose of their time in Afghanistan,” as well as her “cooperation in
    investigations in Europe,” “benefits conferred on Ms. Amal by foreign government officials,”
    and “the current relationship between her and the French security services.” Dkt. 590 at 7. For
    example, he confronted Ms. Amal with what seemed to be one of her prior interviews:
    Q. Do you remember, there was another question that was asked: Did Nizar tell
    you what he was doing in Afghanistan? . . . The answer [was]: No.
    Q. You said we went to Afghanistan to help poor people. . . . You said: I
    remember that we went to Afghanistan with a large sum of money and my
    husband was in the habit of spending over $10,000 per day. . .. [M]y husband
    was giving away bags of flour, of wheat, and he was building mosques and
    wells and houses for the poor.
    A. I don’t remember this, Mr. Trabelsi.
    Apr. 27, 2023 p.m. Dep. (Tr. at 87-89). As to her relationship with foreign law enforcement,
    moreover, Trabelsi asked whether Ms. Amal felt “under pressure or threatened by someone in
    France?” Apr. 26, 2023 p.m. Dep. (Tr. at 47); see also Apr. 27, 2023 a.m. Dep. (Tr. at 9) (Q.
    “Yesterday when we stopped the interview until today, is there any people from the French
    government or the American government who told you what to say today?” A. “No, not at
    all... .”). He also questioned Ms. Amal about any benefits conferred upon her by the French or
    American governments in exchange for her testimony. See, e.g., Apr. 27, 2023 p.m. Dep. (Tr. at
    59
    54) (“So when you came here in 2007 to be interviewed, did the U.S. government promise you
    that you would not be charged?”); id. at 66 (“Did you get anything of value from the U.S.
    government or the French government in relation to my case?”); see id. at 86 (“[I]s it time or is it
    money or the French citizenship that led you to tell the authorities what they wanted to hear?”).
    To be sure, Trabelsi’s cross-examination of Ms. Amal may not have yielded his desired
    results, at least in part because he did not effectively follow up on Ms. Amal’s answers: When
    Ms. Amal answered, for example, that she did not “remember” her prior statements about their
    visit to Afghanistan, Apr. 27, 2023 p.m. Dep. (Tr. at 87-89), Trabelsi did not seek to refresh her
    recollection with an exhibit memorializing her prior inconsistent statement. And when Ms.
    Amal denied receiving anything of value from the United States related to Trabelsi’s
    prosecution, Apr. 27, 2023 p.m. Dep. (Tr. at 63-66), he did not use Exhibit 110, which shows
    that Ms. Amal was paid $2,000.00 by the FBI in 2005, see Dkt. 590-1, to refresh her recollection
    as to that fact. To be sure, an experienced criminal defense attorney could have used these
    exhibits more effectively and would have, in all likelihood, devoted considerably more time to
    cross-examining Ms. Amal about her prior inconsistent statements and about the source of any
    potential bias.'° But, as discussed at length above, it is not the time limitation that precluded
    Trabelsi from engaging in more effective cross-examination about Ms. Amal’s prior inconsistent
    statements or about any benefits she received from the U.S. government. Trabelsi made the
    decision to devote only a small percentage of his time to these topics, and, when she gave
    answers that were inconsistent with Trabelsi’s exhibits, he could have but failed to follow up.
    '6 To the extent that Trabelsi can now offer—consistent with the Rules of Evidence—evidence to
    undercut Ms. Amal’s testimony on direct examination, he is of course welcome to do so.
    60
    Rather than home in on these key issues, he spent the majority of his cross-examination time on
    issues that were (at best) of marginal relevance. That was his choice.
    If Trabelsi had heeded the Court’s warnings to “focus his deposition preparation,” Dkt.
    578 at 14, and to “be as efficient as he can and . . . ask questions that are relevant[,] . . . and [that]
    relate to the direct testimony that the government is eliciting,” Apr. 25, 2023 p.m. Hrg. Tr.
    (Rough at 4—5), he would have had ample time to further explore the topics his counsel now
    proffers as areas for further cross-examination. Tellingly, the defense does not argue in its briefs
    that a seven-hour cross-examination would have been (constitutionally) insufficient to explore
    these proffered topics, had the questioner focused his examination on the relevant issues from the
    outset and throughout the deposition. That Trabelsi chose to squander his opportunity for cross-
    examination on irrelevant, repetitive, and harassing questions, then, does not mean that he was
    deprived of the “opportunity for effective cross-examination.” Miller, 
    738 F.3d at 375
     (emphasis
    added). Opportunity and achievement are not the same thing, and, here, it seems unlikely that
    even days of additional cross-examination would have bridged this divide. Indeed, given the
    volume of Trabelsi’s own cross-examination that his counsel has now moved to strike from the
    record, see Dkt. 618, it is unclear that a further opportunity for cross-examination would have
    been fruitful at all.
    vi. Due process
    Lastly, the Court briefly addresses Trabelsi’s argument that the Court should “strike Ms.
    Amal’s Rule 15 deposition” because Trabelsi was “not afforded procedural due process” at the
    deposition. Dkt. 590 at 15-16. The defense contends that, under the balancing analysis set forth
    in Mathews v. Eldridge, 
    424 U.S. 319
     (1976), and in light of Trabelsi’s strong interest in
    receiving a fair trial, he was entitled to “additional time and opportunity to complete his cross-
    61
    examination.” Dkt. 590 at 16. Under Mathews, “identification of the specific dictates of due
    process generally requires consideration of three distinct factors:”
    First, the private interest that will be affected by the official action; second, the
    risk of erroneous deprivation of such interest through the procedures used, and
    the probable value, if any, of additional or substitute procedural safeguards; and
    finally, the Government’s interest, including the function involved and the fiscal
    and administrative burdens that the additional or substitute procedural
    requirement would entail.
    424 US. at 335.
    The Court notes, at the outset, that it is unclear whether the Mathews’ balancing test for
    identifying “the specific dictates of due process,” 
    id.,
     applies to Trabelsi’s right to cross-
    examination, which is governed by “an explicit textual source of constitutional protection,”
    Elkins v. District of Columbia, 
    690 F.3d 554
    , 562 (D.C. Cir. 2012) (internal quotation marks
    omitted)—namely, the Sixth Amendment’s Confrontation Clause. At least where a claim of
    substantive due process is at issue, the Supreme Court and the D.C. Circuit have explained that
    the constitutional amendment “provid[ing] an explicit textual source of constitutional
    protection,” and “not the more generalized notion of substantive due process, must be the guide
    for analyzing these claims.” Jd. (quoting Albright v. Oliver, 
    510 U.S. 266
    , 273 (1994)). But the
    Supreme Court has also explained that “(t]he right of an accused in a criminal trial to due process
    is, in essence, the right to a fair opportunity to defend against the State’s accusations,” including
    “an opportunity to... examine the witnesses against him, to offer testimony, and to be
    represented by counsel.” Chambers v. Mississippi, 
    410 U.S. 284
    , 294 (1973) (quoting In re
    Oliver, 
    333 U.S. 257
    , 273 (1948)). Although “the right to confront and to cross-examine is not
    absolute and may, in appropriate cases, bow to accommodate other legitimate interests in the
    criminal trial process, . . . its denial or significant diminution calls into question the ultimate
    ‘integrity of the fact-finding process’ and requires that the competing interest be closely
    62
    examined.” Jd. at 295 (internal citation omitted) (quoting Berger v. California, 
    393 U.S. 314
    ,
    315 (1969)).
    In any event, analyzing Trabelsi’s opportunity to cross-examine Ms. Amal under the Due
    Process Clause yields the same result as the Court’s analysis under the Confrontation Clause.
    Considering the Chambers standard, the Court concludes that Trabelsi had an adequate
    opportunity to “confront and to cross-examine” without “significant diminution.” Jd. at 295.
    And Mathews balancing leads the Court to the same outcome: Trabelsi does, of course, have a
    strong “private interest” in his liberty and in the truth-seeking function of cross-examination.
    Mathews, 
    424 U.S. at 335
    . But, as discussed at length above, Trabelsi had the opportunity to
    cross-examine Ms. Amal over the course of seven hours; he simply chose to use that time
    unwisely. The burden on the government of requiring further time, moreover, is substantial
    because Ms. Amal has categorically refused to appear for further cross-examination and because
    she is, as discussed, beyond the Court’s subpoena power. Balancing these factors, and in light of
    Trabelsi’s substantial “opportunity to subject [Ms. Amal] . . . to cross-examination,” Chambers,
    
    410 U.S. at 295
    , the Court reaches the same result under the Due Process Clause as it does under
    the Confrontation Clause.
    CONCLUSION
    For the foregoing reasons, it is hereby ORDERED that the government’s motion to
    admit Ms. Amal’s Rule 15 deposition, Dkt. 588, is GRANTED, and that Defendant’s cross-
    motion to strike Ms. Amal’s testimony, Dkt. 590, is DENIED.
