    ELIZABETH GARCIA DE NIETO,

    Appeal from the United States District Court
    for the Western District of Texas
    Before SMITH, GRAVES, and WILLETT, Circuit Judges.
    JERRY E. SMITH, Circuit Judge:
    Elizabeth Garcia De Nieto was convicted of conspiracy to defraud the
    United States, mail fraud, and aiding and abetting aggravated identity theft.
    De Nieto appeals, challenging the court’s calculation of the loss amount, the
    sufficiency of the evidence to support the verdict that she aided and abetted
    aggravated identity theft, and the court’s disqualification of her original
    attorney for conflict of interest. We affirm.

    I.
    De Nieto would send packages from her house in Mexico to her contacts
    in the United States, including numerous completed tax returns that had been
    preaddressed to the IRS. De Nieto reimbursed her contacts for their expenses
    in sending the tax returns to the IRS and sometimes also paid them.
    The fraudulent returns followed a pattern. Each (1) listed the taxpayer
    as single or as head of household, (2) reported income from self-employment as
    a sole proprietor, usually as a nail technician or a barber, (3) claimed three
    exemptions: the taxpayer and two dependents, who were usually foster chil-
    dren, nieces, or nephews, and (4) claimed a refund of about $5000. Though the
    names and social security numbers corresponded to real persons, those indi-
    viduals did not file the returns or authorize De Nieto to file for them. They
    also did not receive the refunds claimed on the returns because the addresses
    on the returns were not their real addresses but, instead, were addresses of
    De Nieto’s contacts in the United States, who received the checks.
    The contacts would forward the refund checks to De Nieto in Mexico, and
    she would arrange to have them cashed. When refund checks she expected did
    not arrive, she called IRS service centers for assistance.
    The IRS discovered the scheme by investigating a business cashing a
    large number of tax refund checks and determining that the refunds were
    obtained fraudulently. When the IRS visited the addresses that appeared in
    the returns, it learned about De Nieto from the individuals at those addresses.
    Consequently, agents began to intercept packages arriving into the United
    States that had De Nieto’s name and return address and contained numerous
    tax returns that matched De Nieto’s pattern. Shortly thereafter, border agents
    apprehended a man attempting to bring a package of tax returns that matched
    De Nieto’s pattern across the border. The man admitted that he worked for De

    Nieto and that she had provided him with the returns and had instructed him
    to mail them in the United States.
    Agents then called De Nieto, who explained that she was responsible for
    the tax returns, and told her to retrieve them at a port of entry in El Paso. A
    woman named Yolanda Turrubiatez Nuñez came to the port of entry claiming
    to be De Nieto and asking for the tax returns. After agents arrested Turru-
    biatez, she admitted that she was not De Nieto.
    In the presence of her attorney, Kenneth del Valle, Turrubiatez ex-
    plained that De Nieto had instructed her to impersonate De Nieto and to
    retrieve the confiscated tax returns. She also stated that she had witnessed
    De Nieto preparing the seized returns, that De Nieto had given them to the
    man apprehended trying to bring them into the United States, and that De
    Nieto had instructed her to mail other returns to the United States. Turru-
    biatez pleaded guilty of making a false statement in violation of 18 U.S.C.
    § 1001 for her attempt to impersonate De Nieto.
    De Nieto was arrested when she tried to cross from Mexico. After agents
    informed De Nieto of her rights, she acknowledged that she had prepared the
    tax returns seized from the man attempting to bring them into the United
    States. She also admitted that Turrubiatez had attempted to retrieve the
    returns for her, but she contradicted Turrubiatez’s account by claiming that
    she had not known that Turrubiatez would impersonate her.
    A grand jury charged De Nieto in a ten-count indictment. Counts One
    and Ten charged her with conspiring to defraud the United States in violation
    of 18 U.S.C. §§ 371 and 286, respectively. Counts Two through Six charged
    mail fraud in violation of 18 U.S.C. § 1341.      Counts Seven through Nine
    charged aiding and abetting aggravated identity theft in violation of 18 U.S.C.
    §§ 2 and 1028A.

    Early in the prosecution, Turrubiatez’s attorney, del Valle, filed an
    appearance for De Nieto. Because it was possible that a serious conflict of
    interest would arise from del Valle’s representation of both Turrubiatez and
    De Nieto, the government moved to disqualify del Valle as De Nieto’s attorney.
    Without holding a hearing or requesting De Nieto’s response, the district court
    granted the motion and appointed new counsel for De Nieto.
    II.
    At trial, the government presented testimony of De Nieto’s contacts in
    the United States and IRS call center representatives who had spoken with
    De Nieto when she impersonated taxpayers and called to ask about tax
    returns. The government also proffered fraudulent returns consistent with
    De Nieto’s pattern, some filed with the IRS and some seized at the border, and
    refund checks obtained through those fraudulent returns. De Nieto offered no
    testimony or evidence. The jury found her guilty on all counts.
    Based on trial testimony and the IRS’s investigation into De Nieto’s
    fraudulent scheme, the presentence investigation report (“PSR”) estimated
    that De Nieto’s intended loss exceeded $8.2 million. Determining that the
    PSR’s estimate was reliable, the district court adopted this loss amount, trig-
    gering an 18-level increase in De Nieto’s offense level. The court sentenced
    De Nieto to 192 months’ imprisonment and $3,009,999.80 in restitution.
    De Nieto appealed, and del Valle filed her opening brief. After the gov-
    ernment brought to this court’s attention del Valle’s previous disqualification,
    the court suspended briefing and ordered a limited remand “so that a record
    as to the conflict and possibility of waiver c[ould] be better developed.” On that
    remand, the district court held a hearing regarding whether del Valle could
    represent De Nieto on appeal. The court considered De Nieto’s testimony and
    each party’s contentions and determined that del Valle be disqualified from the
    4

    appeal. It then appointed new counsel for De Nieto, and this appeal resumed.
    On appeal, De Nieto challenges (1) the calculation of the loss amount,
    (2) the sufficiency of the evidence to support the verdict that she aided and
    abetted aggravated identity theft, and (3) the disqualification of De Nieto’s
    original attorney for conflict of interest. She also asserts that (4) even if the
    court’s various errors do not warrant reversal on their own, the judgment
    should be reversed for cumulative error.
    III.
    De Nieto challenges the district court’s reliance on the PSR’s loss
    estimate, contending “that the extrapolation of 1,727 fraudulent returns and
    the extrapolation of an $8,480,425.00 dollars loss are not based on any evidence
    presented at trial and that the extrapolations are clearly erroneous.” She
    asserts that “most of the [fraudulent returns] were never linked to [her] at trial
    yet they were used to estimate the [loss] applicable to her.” She raises “the
    problem of multiple conspiracies” engaged in the same criminal activity as was
    she, and consequently her “criminal liability is left unresolved.” De Nieto’s
    contentions are unavailing, and she does not satisfy her burden of demon-
    strating that the information in the PSR is “inaccurate or materially untrue.”

    A.
    We review for clear error the factual findings of whether a loss resulted
    from an offense. United States v. Bazemore, 
    839 F.3d 379
    , 387 (5th Cir. 2016)
    (per curiam). “A finding is ‘clearly erroneous’ when although there is evidence
    to support it, the reviewing court on the entire evidence is left with the definite
    and firm conviction that a mistake has been committed.” United States v. U.S.
    Gypsum Co., 
    333 U.S. 364
    , 395 (1948). But “[t]here is no clear error if the
    5

    district court’s finding is plausible in light of the record as a whole.” United
    States v. Harris, 
    597 F.3d 242
    , 250 (5th Cir. 2010) (citation omitted).
    Given the district court’s “unique position to assess the evidence and
    estimate the loss” amount, its “loss determination is entitled to appropriate
    deference.”   U.S.S.G. § 2B1.1 cmt. 3(C); see also United States v. Hebron,
    
    684 F.3d 554
    , 560 (5th Cir. 2012). Thus, this court gives “wide latitude” to the
    district court “to determine the amount of loss.”       United States v. Jones,
    
    475 F.3d 701
    , 705 (5th Cir. 2007). The district “court need only make a rea-
    sonable estimate of the loss,” U.S.S.G. § 2B1.1 cmt. 3(C), based on available
    information, 
    Jones, 475 F.3d at 705
    . The loss amount “need not be determined
    with precision,” United States v. Reasor, 
    541 F.3d 366
    , 369 (5th Cir. 2008), nor
    “absolute certainty,” United States v. Goss, 
    549 F.3d 1013
    , 1019 (5th Cir. 2008).
    “[I]n making its loss-amount estimate,” “[a] district court may rely upon
    information in the PSR . . . so long as that information bears some indicia of
    reliability.” 
    Danhach, 815 F.3d at 238
    (internal quotation marks and citation
    omitted). When a defendant challenges a PSR’s loss estimate, “he bears the
    burden of presenting rebuttal evidence to demonstrate that the information in
    the PSR is inaccurate or materially untrue.” 
    Id. (cleaned up).
    The Sentencing Guidelines state that the loss is “the greater of actual
    loss or intended loss.” U.S.S.G. § 2B1.1 cmt. 3(A). An “actual loss” is “the rea-
    sonably foreseeable pecuniary harm that resulted from the offense.”             
    Id. § 2B1.1
    cmt. 3(A)(i). An “intended loss” is “the pecuniary harm that the defen-
    dant purposely sought to inflict,” even if that harm “would have been impossi-
    ble or unlikely to occur.” 
    Id. § 2B1.1
    cmt. 3(A)(ii).
    B.
    The district court utilized the intended loss, which exceeded the actual
    loss because not all the returns submitted under De Nieto’s scheme resulted in
    6
    Case: 16-51142     Document: 00514937111      Page: 7   Date Filed: 04/30/2019
    No. 16-51142
    refunds. To estimate that intended loss, the court relied on the PSR, which
    connected De Nieto to 1727 fraudulent returns together claiming refunds of
    more than $8.2 million. The court found that the PSR contained “sufficiently
    reliable information” and that it bore “indicia of reliability.”
    The court did not err in making that reliability determination. To calcu-
    late the estimated intended loss, the PSR analyzed the investigative reports
    and trial testimony of IRS agents who had investigated De Nieto’s scheme,
    including a chart that summarized their findings. Examining returns that
    De Nieto admitted to completing, returns that witnesses identified De Nieto as
    having completed, and returns from addresses that repeatedly appeared on
    cashed, fraudulently obtained refund checks where individuals had implicated
    De Nieto, agents first compiled a list of addresses. They next gathered the
    1727 returns associated with those addresses that claimed a refund. Those
    returns followed a similar pattern, (1) listing the taxpayer as single or head of
    household, (2) reporting income only from self-employment as a sole proprietor
    using one of three business codes (often for nail salons or barber shops),
    (3) claiming three exemptions, the taxpayer and two dependents, and
    (4) claiming a refund through the earned-income tax credit of about $5000. As
    the district court noted, these similarities strongly supported the inference
    that De Nieto was the source of all the returns. Therefore, in relying on the
    PSR, which in turn relied on the agents’ investigation, the court reasonably
    determined that De Nieto intended the loss that would have resulted from the
    1727 fraudulent returns.
    De Nieto attempts to undermine that estimate of loss from numerous
    angles, none of which satisfies her burden of demonstrating that the informa-
    tion in the PSR is inaccurate or materially untrue. De Nieto’s main theory is
    that someone else could have been responsible for some of the fraudulent
    7
    Case: 16-51142    Document: 00514937111     Page: 8   Date Filed: 04/30/2019
    No. 16-51142
    returns linked to her, such as other individuals involved in a separate con-
    spiracy engaging in the same criminal activity. She supports that contention
    with trial testimony establishing that other persons also used the technique of
    submitting fraudulent tax returns with stolen identifies to obtain refunds.
    Aside, however, from generalized averments to the possibility of another con-
    spiracy, De Nieto does not offer evidence demonstrating that another con-
    spiracy utilized her “signature” pattern for completing the returns. Without
    “evidence that rebuts the PSR on the loss amount,” De Nieto’s mere speculation
    is insufficient to show that the PSR was unreliable or that the district court
    erred in adopting it. See 
    Danhach, 815 F.3d at 238
    .
    Aside from the overriding theory of mistaken attribution, De Nieto’s
    challenge to the loss amount calculation is replete with contentions premised
    on mistaken understandings of the record or the law. First, she asserts that
    she cannot be held accountable for fraudulent returns dating back to 2010
    because the IRS’s investigation did not identify her until 2014.       De Nieto
    ignores the obvious reality that investigations often uncover criminal activity
    that occurred before the investigation’s commencement. Moreover, evidence
    established that De Nieto had been operating her scheme as early as 2008.
    Second, De Nieto protests that the evidence did “not clearly parse out
    which transactions reflected in the [IRS’s summary] chart are attributable to”
    her. Nevertheless, the district court’s estimate of the loss need only be reason-
    able, and therefore the court properly relied on connections established by
    De Nieto’s pattern of fraudulent returns.
    Third, De Nieto derides the IRS’s summary chart by characterizing it as
    incorporating any return investigators deemed “not ‘typical.’” That description
    is plainly incorrect. The IRS gathered the 1727 returns by identifying all
    returns that fit De Nieto’s pattern connected with addresses linked to her.
    8
    Case: 16-51142       Document: 00514937111         Page: 9    Date Filed: 04/30/2019
    No. 16-51142
    Fourth, De Nieto states that searches at some of the addresses the IRS
    relied on revealed “no evidence of any illegal activity and [had] no connection
    to” De Nieto. The record refutes this contention. Witnesses interviewed at
    those addresses implicated De Nieto in the scheme, and investigators learned
    that the “addresses were being used to collect and receive refund checks” that
    “were being passed off or forwarded to Ms. De Nieto in . . . Mexico.”
    Fifth, De Nieto erroneously states that the IRS “assigned a refund of
    approximately $5,000.00 to each [tax return]” incorporated in the summary
    chart. The summary chart actually lists the exact amount each return claimed.
    Sixth, De Nieto purports to identify contradictions in the trial testimony
    regarding the loss amount. She misconstrues the testimony. As the PSR
    reflected, the IRS’s investigation connected 1727 fraudulent returns to
    De Nieto that claimed over $8.2 million in refunds. A subset of those 1727
    returns resulted in refund checks that were cashed for more than $2.9 million.
    A different subset of the 1727 returns came from packages seized by law
    enforcement with claimed refunds totaling over $1.2 million. Thus, there was
    no inconsistency in the loss amount testimony.
    Seventh, De Nieto attacks the loss amount by asserting that it was based
    on “supposition” regarding her connection to other groups. Again, the PSR
    estimated the loss amount by analyzing De Nieto’s conduct, not that of other
    groups, a fact readily apparent from the government’s case at sentencing. 1
    Eighth, and finally, De Nieto contends that one of her U.S. contacts did
    not participate in the scheme long enough to generate an intended loss of over
    1 The government stated that “while there are different groups conducting a similar
    scheme . . . what is before this Court is the four corners of the superseding indictment.” It
    then explained that “what we’re dealing with in the superseding indictment is . . . the tax
    returns that are specifically attributed to Ms. [De Nieto].”
    9

    No. 16-51142
    $8.2 million. De Nieto selectively ignores the fact that she had multiple con-
    tacts in the United States, meaning that the government did not have to estab-
    lish that a single person generated all of the intended loss.
    De Nieto’s various contentions are meritless in the face of the record
    evidence and the law. She does not proffer evidence that demonstrates that
    the district court relied on a PSR containing inaccurate or materially untrue
    information. The court’s loss estimate was reasonable and plausible in light of
    the record as a whole and thus was not error, let alone clear error.
    IV.
    De Nieto maintains that the evidence was insufficient to prove beyond a
    reasonable doubt that she aided and abetted the aggravated identity theft of
    the three victims. De Nieto concedes that some “person(s) . . . committed the
    identity theft of the . . . three victims” but asserts that the government “failed
    to prove . . . beyond a reasonable doubt” that she was “associated with the
    criminal venture that stole and or misused the identity of the three victims.”
    Consequently, “no reasonable trier of fact could conclude that [De Nieto] was
    guilty of aiding and abetting . . . the identity theft.” To the contrary, viewing
    the evidence in the light most favorable to the prosecution, making all infer-
    ences in the prosecution’s favor, and showing high deference to the verdict, a
    jury rationally could have found that De Nieto took an affirmative act in fur-
    therance of the aggravated identity theft with the intent of facilitating the
    commission of that offense.

    swims upstream.” United States v. Mulderig,

    rational trier of fact could have found the essential elements of the crime
    beyond a reasonable doubt.” United States v. Vargas-Ocampo,

    out lawful authority (4) during and in relation to a felony enumerated in

    liability to anyone who “aids, abets, counsels, commands, induces or procures”

    572 U.S. 65
    , 71 (2014). The statute’s
    purview is broad, “comprehend[ing] all assistance rendered by words, acts,
    encouragement, support, or presence . . . even if that aid relates to only one (or
    some) of a crime’s phases or elements.” 
    Id. at 73
    (internal quotation marks
    and citation omitted).
    B.
    There is sufficient evidence in the record to support the jury’s verdict.
    First, De Nieto called the IRS using the social security number of one of the
    victims, J.R., to ask about one of the fraudulent returns.           Second, the
    11
    Case: 16-51142   Document: 00514937111      Page: 12   Date Filed: 04/30/2019
    No. 16-51142
    fraudulent returns using the victims’ names and social security numbers
    matched De Nieto’s pattern. Each return listed a filing status of single or head
    of household, claimed two foster children, nieces, or nephews as dependents,
    reported self-employment at a nail salon, and claimed a refund of about $5000.
    Third, the fraudulent returns included addresses associated with
    De Nieto. The return submitted using B.C.G.’s information, which formed the
    basis for Count Seven, used an address that was the home of one of De Nieto’s
    U.S. contacts who received packages containing fraudulent returns from
    De Nieto and forwarded the refund checks they generated back to De Nieto.
    Moreover, De Nieto used the address when she called the IRS impersonating
    a different identity-theft victim. The fraudulent return submitted using E.O.’s
    information, which formed the basis for Count Eight, used an address that was
    a business address where one of De Nieto’s U.S. contacts opened a post office
    box to receive tax-related mailings at De Nieto’s instruction.      Finally, the
    fraudulent return submitted using J.R.’s information, which formed the basis
    for Count Nine, used an address that De Nieto claimed as her home address
    when she was arrested and whose occupant testified that De Nieto sent fraud-
    ulent returns there and used that address to receive refund checks.
    De Nieto does not seriously contest the connections between this
    evidence and herself but instead deflects liability to an unspecified “group of
    persons that stole and misused the three identities.” But contrary to her
    assertion that “there is no direct or circumstantial evidence linking her to the
    aiding and abetting the theft or misuse of the three specific identifications in
    question,” the evidence detailed above would allow a jury rationally to conclude
    beyond a reasonable doubt that De Nieto took affirmative acts in furtherance
    of the aggravated identity theft with the intent of facilitating the commission
    of the offense.
    12

    V.
    De Nieto asserts that the district court violated her Sixth Amendment
    right to counsel by disqualifying her original trial court attorney, del Valle,
    without first holding a hearing. She contends that “[i]n each and every case
    that has dealt with this issue, the district court has held a hearing to divine
    the facts to determine whether an actual or perceived conflict of interest
    exists.” De Nieto identifies no abuse of discretion in the disqualification of
    del Valle, and precedent belies her contention that a court must inevitably hold
    a hearing in every case. Even assuming that the court abused its discretion by
    not holding a hearing, that supposed error was harmless.
    A.
    This court “will not reverse a district court’s disqualification of counsel
    for conflict unless the defendant can show the district court abused its substan-
    tial discretion in this area.” United States v. Gharbi, 
    510 F.3d 550
    , 553 (5th
    Cir. 2007). “A district court abuses its discretion if it: (1) relies on clearly
    erroneous factual findings; (2) relies on erroneous conclusions of law; or
    (3) misapplies the law to the facts.” Fornesa v. Fifth Third Mortg. Co., 
    897 F.3d 624
    , 627 (5th Cir. 2018) (citation omitted).
    “[W]hile the right to . . . be represented by one’s preferred attorney is
    comprehended by the Sixth Amendment, the essential aim of the Amendment
    is to guarantee an effective advocate for each criminal defendant rather than
    to ensure that a defendant will inexorably be represented by the lawyer whom
    he prefers.” Wheat v. United States, 
    486 U.S. 153
    , 159 (1988). Therefore, the
    “right to choose one’s own counsel is circumscribed in several important
    respects.” 
    Id. For example,
    “the right to counsel of choice is limited if that
    counsel has an actual conflict of interest or a serious potential conflict of inter-
    est that may arise during trial.” United States v. Jackson, 
    805 F.3d 200
    , 202

    No. 16-51142
    (5th Cir. 2015). “[W]hile we recognize a presumption that a defendant is enti-
    tled to counsel of choice, that presumption may be rebutted by a showing of
    actual or potential conflicts of interest.” 
    Id. Whether a
    party has met its bur-
    den to demonstrate these conflicts of interest “must be left primarily to the
    informed judgment of the trial court.” 
    Wheat, 486 U.S. at 164
    .
    Defendants may waive conflicts of interest in some situations. See 
    id. at 162.
    Nevertheless, the district court must be ever wary of “the subtle prob-
    lems implicating the defendant’s comprehension of the waiver” to protect “the
    integrity of the court” and defend against “future attacks over the adequacy of
    the waiver or the fairness of the proceedings.” 
    Id. (citation omitted).
    Even “[a]
    valid waiver does not end the inquiry because the district court has an inde-
    pendent interest in ensuring that criminal trials are conducted within the
    ethical standards of the profession and that legal proceedings appear fair to all
    who observe them.” 
    Gharbi, 510 F.3d at 553
    (internal quotation marks and
    citation omitted). Consequently, given the delicate balancing of a defendant’s
    Sixth Amendment rights with “nascent conflicts of interest [that] are notori-
    ously hard to predict,” “the district court must be allowed substantial latitude
    in refusing waivers of conflicts of interest . . . where an actual conflict may be
    demonstrated before trial [and] where a potential for conflict exists which may
    or may not burgeon into an actual conflict as the trial progresses.” 
    Wheat, 486 U.S. at 162

    B.
    The district court did not abuse its discretion in disqualifying De Nieto’s
    attorney. Del Valle had previously represented Turrubiatez in a related case
    and thus risked multiple conflicts of interest between his current client,
    De Nieto, and his former client. He would have faced an intractable conflict
    between his duty to keep his communications with Turrubiatez confidential,
    14
    Case: 16-51142         Document: 00514937111           Page: 15     Date Filed: 04/30/2019
    No. 16-51142
    and his duty to consider appropriate courses of action for De Nieto free from
    professional and ethical restrictions that would foreclose alternatives that
    otherwise would have been available to her. 2
    Indeed, De Nieto pleaded not guilty, denied involvement in the fraudu-
    lent tax return scheme, and denied that she had instructed Turrubiatez to
    impersonate her at the border, but Turrubiatez, as part of her guilty plea, had
    implicated De Nieto in the scheme and had accused De Nieto of instructing her
    to impersonate De Nieto. Consequently, del Valle, by having represented Tur-
    rubiatez and attempting to represent De Nieto, would have been put into the
    position of admitting either that Turrubiatez had lied to the court in her guilty
    plea or that De Nieto had lied to federal officials in her post-arrest interview.
    Moreover, the government asserted that “[t]here [was] little doubt that
    TURRUBIATEZ NUNEZ would be a . . . witness against GARCIA DE NIETO
    at any trial or proceeding.” Del Valle thus would have been required to cross-
    examine his former client testifying against his current client, violating his
    professional and ethical obligations. 
    Wheat, 486 U.S. at 164
    ; MODEL RULES OF
    PROF’L CONDUCT r. 1.7 cmt. 6 (AM. BAR ASS’N 2015). Thus, as the district court
    considered the government’s motion to disqualify, it was readily apparent that
    an actual conflict of interest, or, at the very least, a serious potential conflict of
    interest could have arisen at trial.
    The decision to disqualify del Valle was not an abuse of discretion even
    2   See Tex. Disciplinary Rules of Prof’l Conduct r. 1.05 (governing confidentiality of
    information); r. 1.06(b)(2) (“[A] lawyer shall not represent a person if the representation of
    that person . . . reasonably appears to be or become adversely limited by the lawyer’s
    . . . responsibilities to another client or to a third person or by the lawyer’s . . . own inter-
    ests.”); 
    id. r. 1.06
    cmt. 4 (“Loyalty to a client is impaired . . . in any situation when a lawyer
    may not be able to consider, recommend or carry out an appropriate course of action for one
    client because of the lawyer’s own interests or responsibilities to others.”);

    ing conflicts of interest between present and former clients);

    considering a potential waiver of conflict by De Nieto. Del Valle’s representa-
    tion of De Nieto raised the specter of serious potential conflicts of interest,
    conflicts that could have resulted in the inadequate representation of De Nieto,
    breaches of professional responsibility and ethics, and the undermining of the
    court’s integrity and soundness of its proceedings and eventual judgment that
    would have persisted despite waiver. Therefore, the district court was well
    within its “substantial latitude in refusing waivers of conflicts” when it dis-
    qualified del Valle. See 
    Wheat, 486 U.S. at 163
    .
    De Nieto urges that in every situation, a court must hold a hearing before
    granting a motion to disqualify counsel. She is incorrect. In United States v.
    Ahmad, No. 95-50075, 
    1995 WL 449667
    , at *7 (5th Cir. July 13, 1995), 3 this
    court affirmed the disqualification of an attorney without a hearing, finding
    “no abuse of discretion.” Thus, the procedural fact that the district court did
    not hold a hearing before disqualifying del Valle is not fatal. Furthermore, a
    hearing was not necessary to uncover nuanced, hidden conflicts. The actual
    and potential conflicts involved in del Valle’s representation of De Nieto were
    apparent from the record, the government’s motion, and the record of Turru-
    biatez’s case, which was before the same district judge.
    Even assuming that it was an abuse of discretion not to hold a hearing
    before disqualifying del Valle, that purported error was harmless. On limited
    remand, the district court held a hearing to determine whether del Valle could
    represent De Nieto on appeal. The court found that del Valle could not, deter-
    mining that he was “still disqualified from representing” De Nieto for the same
    reasons the government had identified in its original motion to disqualify.
    De Nieto does not contend that the disqualification ruling at that point was
    3   Unpublished decisions issued before 1996 are precedential. See 5TH CIR. R. 47.5.3.

    erroneous. Thus, the record strongly suggests that a hearing would not have
    changed the decision. So any error was harmless and did not affect De Nieto’s
    substantial rights. 4
    VI.
    De Nieto urges that “even if [this court] determine[s] that the errors . . .,
    standing alone, were insufficiently prejudicial to warrant reversal, [her] con-
    viction should be reversed because taken together, the aggregate effect gives
    rise to substantial prejudice.” “Cumulative error justifies reversal only when
    errors so fatally infect the trial that they violated the trial’s fundamental fair-
    ness.” United States v. Delgado, 
    672 F.3d 320
    , 344 (5th Cir. 2012) (en banc)
    (cleaned up). This court has “repeatedly emphasized that the cumulative error
    doctrine necessitates reversal only in rare instances.” 
    Id. Thus, “the
    possibility
    of cumulative error is often acknowledged but practically never found persua-
    sive.” Derden v. McNeel, 
    978 F.2d 1453
    , 1456 (5th Cir. 1992) (en banc).
    De Nieto has not established that the district court erred in any respect.
    Therefore, “the cumulative error doctrine has no applicability to [De Nieto’s]
    allegations of error.” 5 The judgment of sentence is AFFIRMED.
    4 See FED. R. CRIM. P. 52(a) (“Any error, defect, irregularity, or variance that does not
    affect substantial rights must be disregarded.”).
    5 
    Delgado, 672 F.3d at 344
    ; see also 
    id. (“Because we
    have rejected [defendant’s] other
    allegations of error, and non-errors have no weight in a cumulative error analysis, there is
    nothing to accumulate.”).
