    Before BAUER, MANION, and SYKES, Circuit Judges.
    MANION, Circuit Judge. Monta Groce appeals witness-
    retaliation and sex-trafficking convictions. The government
    concedes the retaliation jury instruction failed to state a
    particular unsupported element. We vacate the retaliation
    conviction and remand for resentencing. Regarding sex
    trafficking, Groce raises several challenges. He argues the
    court erred by 1) excluding evidence of the victims’ alleged
    prostitution histories; 2) barring cross-examination of a victim
    2                                                         No. 16-3845
    on her alleged prostitution history after she testified she had
    no such history; 3) issuing an instruction lowering the mens
    rea required for sex trafficking; and 4) admitting prejudicial
    evidence of uncharged sex trafficking. He also argues
    cumulative error requires retrial. We affirm the sex-trafficking
    convictions.
    I. Background 1
    Groce faced nine counts: 1–3) sex trafficking; 4) conspiracy
    to engage in interstate transportation for prostitution; 5)
    interstate transportation for prostitution; 6) maintaining a
    drug house; 7) using or carrying a firearm in maintaining the
    drug house; 8) attempted sex trafficking; and 9) witness
    retaliation. The jury heard evidence he abused and coerced
    two women to cause them to prostitute involuntarily. He
    preyed on their drug addictions and other vulnerabilities,
    manipulated debts, and physically abused or threatened
    them. The jury also heard evidence he caused a third woman
    to prostitute involuntarily. He was convicted on all but Count
    8, and sentenced to 25 years in prison. He only appeals the
    sex-trafficking and retaliation convictions.
    A. Lisa Tischer (Count 1)
    When Lisa Tischer met Groce in November 2012, she was
    a heroin addict. He led her to believe he had romantic feelings
    for her. Soon she lost her job and violated drug-related
    probation. He offered a place to stay, so she lived with him in
    Sparta, Wisconsin. He gave her heroin. At first he did not
    charge or she paid $30 to $40. Soon he said she could do

    calls—have sex for money—to get heroin from him. Groce
    said if she loved him, she would do the calls. He told her she
    would earn $150 to $500. So she prostituted. He arranged and
    controlled the prostitution. At first she got 40% and did five to
    fifteen calls on an average day. She continued using heroin,
    buying it with prostitution funds. He reduced her share.
    Finally, he wanted it all. He imposed rules, and isolated and
    punished her. She could only leave if he approved. He
    slapped her face and fined her $500 for meeting with
    someone. He said she was disgusting and he advertised her
    for full service for $50. She tried to leave but he stopped her
    by guarding the stairs. He controlled her heroin access and
    induced her to prostitute before giving her heroin. He
    withheld heroin if she tried to leave or keep money. She felt
    “dope sick,” “[v]ery sick, depressed, useless.” He burned her
    with a cigarette when she kept funds. After hearing she talked
    to the police, he said he would rape and kill her mother and
    sister. Tischer testified she did not want to do calls, but did
    them to make him happy and to avoid dope sickness. Once,
    when he was out, she used his phone to get a ride to leave.
    But he returned, saw her stuff packed, slapped her face a few
    times, and made her stay downstairs. Once, he threatened to
    kill a young man and told her to get his gun. She hesitated.
    Groce said if she did not get it, he would get it and she and
    the man would be sorry. So she got the gun for Groce.
    She left around January 2013, but he found her. He said he
    changed and was sorry. So she moved into his small room.
    After locking her in twice, he asked her to do a call. She
    refused. He locked her in again. She felt withdrawals. He said
    she must do a call. Seeing it as her only escape, she did it.
    Later, he beat her for reporting to authorities.

    B. Mirika Stuhr (Count 2)
    Mirika Stuhr met Groce in November 2012. He supplied
    her heroin. She started living with him at the Sparta house.
    She had a “crush” on him. After suffering much abuse,
    including a cigarette burn to her face, Tischer got a ride and
    left with Stuhr’s help. Groce blamed Stuhr and asked her to
    do a call. She agreed, but Groce had to teach her what to do.
    Groce kept $60, gave her $40, and also gave her heroin. She
    was addicted and regularly bought it from him. She testified
    heroin addiction means “you can’t go without it. It means you
    will do anything at any cost to make sure that you have it.”
    She testified she had never taken calls for anyone else.
    She continued prostituting. Groce cut off free heroin. So
    she used her $40 a call to buy it, but he charged $50. So she
    always owed him. She had trouble leaving because if she
    missed a call she would owe him. He took her phone
    sometimes. Once, he allowed her out, so she left and used
    meth. Then he called to say she had a customer. She returned
    around 3:00 am. She had picked her legs bloody and raw due
    to meth. Unable to sit still, she asked for heroin so she could
    do the call. But he refused as she had missed calls and owed
    him. She said she could not do it. He eyed his gun and said,
    “‘You always have a choice.’” Scared, mad, and alone, she
    cried and did the call. Besides owing for drugs and missing
    calls, she also owed for unplugging his phone while cleaning,
    taking too long on his laundry, and failing to report. Once,
    when she withheld funds, he told her she was a dead duck,
    was cut off, and would not get calls or drugs. She felt scared,
    alone. Once, he punished her by isolating her, taking her
    phone, and depriving her of drugs and food. Suicidal,
    suffering withdrawal, and under a warrant, she had nowhere
    No. 16-3845                                                    5
    to go. Finally he asked, “‘Are you ready to make some
    money[?]’” meaning, “Are you ready to take a call[?]” Her
    testimony shows her dungeon’s depravity: “In one way that’s
    all I mattered for and on one side, thank God I can finally feel
    better.” After she took a call on Groce’s bed, he beat her, and
    she left. But she suffered withdrawals and resumed buying
    drugs from him. She later lived with him again and continued
    prostituting, giving him all the funds. She still used drugs.
    She also testified about texts tending to corroborate her.
    C. Amanda Ryan (Count 3)
    Amanda Ryan was a certified nursing assistant on heroin
    when she moved to the Sparta house. She could not function
    without drugs, which Groce sold her. Struggling to pay, she
    agreed to prostitute “against [her] better judgment.” She kept
    prostituting for him, halving the funds, but using hers to buy
    drugs from him. He was “manipulative, narcissistic,
    controlling.” He “had the heroin, so it was basically what he
    said goes.” He “had a gun and he wasn’t afraid to show it.”
    She lost his debit card. He insisted she prostitute to repay. She
    said she had to go to work. He persisted: “‘You’re not going
    until you do this call, otherwise I’m cutting you off—I’m not
    giving you any heroin.’” Seeing no choice, she did a call
    against her will, felt like trash, then got drugs. She did not
    really want to do any calls, but only did them for drugs. Groce
    threatened to cut her off.
    D. Melissa Copeland (Count 4—not appealed)
    Melissa Copeland testified she and Groce were childhood
    friends. In April 2013, he asked if she wanted to make $150
    and she agreed. She considered him a friend and did not think
    he meant anything harmful. Someone drove her to a
    6                                                 No. 16-3845
    residence, which she entered, still not knowing what to
    expect. A male asked her to engage in a sex act. She did. He
    paid. The driver returned her to Groce, who demanded
    money. When she refused he threw her down, forced her
    head to the pavement, reached in her bra, and took some
    money. She saw his gun. He said essentially, “‘They’re not
    going to catch me.’” She testified she had never done anything
    like that before. On cross Groce’s attorney challenged her,
    asking if she remembered prostituting in Milwaukee. She
    again denied being a prostitute. The attorney pressed: “Never
    done that before?” She responded: “I don’t even have it on my
    record.” The government objected, and the court sustained.
    II. Discussion
    Groce appeals multiple issues. We evaluate his arguments
    in turn.
    A. Witness-retaliation conviction
    Groce seeks dismissal of the retaliation conviction because
    the instruction lacked an element: the witness communicated
    with a federal officer. The government concedes. The
    instruction was erroneous, and the evidence did not support
    conviction. We vacate the Count 9 conviction and remand for
    resentencing on the remaining convictions.
    B. Exclusion of victims’ alleged prostitution histories
    For sex trafficking, the government had to prove Groce
    acted “knowing, or in reckless disregard of the fact, that
    means of force, threats of force, fraud, coercion … or any
    combination of such means will be used to cause the person
    No. 16-3845                                                            7
    to engage in a commercial sex act.” 18 U.S.C. § 1591(a). 2 Groce
    insists he could not have known or recklessly disregarded
    that force, et cetera, would be used to cause the victims to
    prostitute because he knew they prostituted before working
    for him. He claims the victims’ prostitution histories were
    relevant to his mens rea and the court erred by excluding this
    evidence under Rule 412, yet it allowed the government to
    elicit testimony from Stuhr that she never prostituted before
    meeting Groce. He contends this gutted his defense.
    Specifically, under Rule 412(a) the government moved in
    limine to exclude evidence of the victims’ other sexual
    behavior or sexual predisposition. It also sought exclusion per
    Rule 403 for unfair prejudice and potential confusion. Groce
    claimed relief under the Rule 412(b)(1)(C) “constitutional
    rights” exception. Relying on United States v. Cephus, 
    684 F.3d 703
    , 708 (7th Cir. 2012), the court excluded the evidence per
    Rule 412, and agreed Rule 403 also bars it.
    Groce seeks de novo review, claiming the exclusion
    violated his constitutional rights. But the government urges
    only plain-error review because the basis for Groce’s
    challenge on appeal is new: below he claimed the victims’
    prior prostitution was relevant to whether they voluntarily
    prostituted for him; but now he claims it was relevant to his
    mens rea. Usually we review evidentiary decisions for abuse
    of discretion. See United States v. Fifer, 
    863 F.3d 759
    , 767 (7th
    Cir. 2017). But under any standard, Groce loses.
    Federal Rule of Evidence 412(a) bars “evidence offered to
    prove that a victim engaged in other sexual behavior.” An
    2 We refer to “means of force, threats of force, fraud, coercion … or any
    combination of such means” as “force, et cetera.”
    8                                                  No. 16-3845
    exception allows admission of “evidence whose exclusion
    would violate the defendant’s constitutional rights.” Fed. R.
    Evid. 412(b)(1)(C). Groce claims the evidence of the victims’
    prior prostitution was vital as virtually the only evidence of
    his state of mind. He argues if the jury knew he knew of the
    prior prostitution, it might have concluded he reasonably
    believed the women were prostituting voluntarily. Or if not,
    at least it could have concluded he was not criminally reckless
    in disregarding the fact that force, et cetera, would be used to
    compel them to prostitute. Groce argues Ryan was
    legitimately employed, willingly engaged in prostitution to
    support her heroin habit, and independently expanded her
    prostitution business. He claims he never threatened her with
    force. He argues he only denied Tischer and Stuhr heroin
    when they could not pay for it. He insists none of the violence
    against them was used to compel prostitution. His basic point
    is he could not have known or recklessly disregarded that
    force, et cetera, were used to compel the women to prostitute
    because he knew they were already prostitutes.
    This argument fails for several reasons. Most importantly,
    we already rejected it. In United States v. Cephus, we said,
    “even if [a victim] knew going in, from her prior [prostitution]
    experience, that [defendant] probably would beat her, it was
    still a crime for him to do so.” 
    Cephus, 684 F.3d at 708
    . Groce
    argues Cephus did not address the relevance of the victims’
    prior prostitution to a defendant’s state of mind, but only
    prohibited the use of prior prostitution to prove the victims’
    consent to subsequent prostitution. But, as the government
    notes, we recently rejected that argument in United States v.
    Carson, where we held a victim’s prior sexual conduct is
    irrelevant to the sex-trafficking mens rea: “whether the victims
    had previously worked as prostitutes was irrelevant to the
    No. 16-3845                                                             9
    required mens rea for the crime.” Carson, 
    870 F.3d 584
    , 593 (7th
    Cir. 2017). Groce ultimately concedes Carson forecloses his
    argument. He asks us to overrule Carson, but we decline. The
    district court did not err when it excluded irrelevant
    evidence. 3
    C. Stuhr’s testimony regarding lack of prior prostitution
    The government elicited testimony from Stuhr that she
    never prostituted before meeting Groce. He complains that
    despite a proffer that this testimony was untrue, the court
    refused to allow him to cross her on this issue, thereby
    violating his right to confront the government’s key witness.
    As noted, Groce concedes Carson forecloses his argument that
    Tischer’s and Ryan’s prior prostitution was relevant to his
    mens rea. Still, he argues Carson does not control the outcome
    regarding Stuhr because unlike the government in Carson, the
    government here elicited testimony that Stuhr had not
    previously prostituted. Groce claims the government opened
    the door and put her prostitution history at issue.
    A court has broad discretion to limit cross, within the
    Confrontation Clause’s bounds. 
    Carson, 870 F.3d at 596
    . The
    Confrontation Clause “guarantees a defendant an
    opportunity for effective cross-examination, but there is no
    guarantee of cross-examination to whatever extent the
    defense might wish.” United States v. Recendiz, 
    557 F.3d 511
    ,
    530 (7th Cir. 2009) (internal quotation marks and alteration
    3  Moreover, overwhelming evidence established he did not merely
    recklessly disregard that his conduct caused the victims to prostitute. He
    knew it. The evidence showed a pattern of physical abuse, threats, and
    coercion including controlling heroin access and manufacturing debt. He
    was not merely a bystander; he was the controller and actor.
    10                                                  No. 16-3845
    omitted). We review a limit on cross de novo if it directly
    implicates the Confrontation Clause’s core values; otherwise
    we review for abuse of discretion. 
    Id. Impeaching a
    witness is
    a core value. United States v. Clark, 
    657 F.3d 578
    , 583 (7th Cir.
    2011). Exposing “a witness’s motivation, biases or incentives
    for lying” is a core value. 
    Carson, 870 F.3d at 597
    . But “once a
    trial court permits a defendant to expose a witness’s
    motivation, it is of peripheral concern to the Sixth
    Amendment how much opportunity defense counsel gets to
    hammer that point home to the jury.” 
    Recendiz, 557 F.3d at 530
    (internal quotation marks omitted). The Confrontation Clause
    “does not give a defendant a boundless right to impugn the
    credibility of a witness.” 
    Clark, 657 F.3d at 584
    . The court has
    “wide latitude … to impose reasonable limits on such cross-
    examination based on concerns about … 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). “If the
    defendant already has had a chance to impeach the witness’s
    credibility and establish that she has a motive to lie, then any
    constitutional concerns vanish and we review the district
    court’s decision to limit additional inquiries only for abuse of
    discretion.” 
    Clark, 657 F.3d at 584
    ; see also United States v.
    Kielar, 
    791 F.3d 733
    , 743 (7th Cir. 2015). Even if the court errs
    in barring cross, “that error is harmless depending upon
    factors such as the importance of the witness’s testimony in
    the prosecution’s case, whether the testimony was
    cumulative, the presence or absence of corroborating or
    contradictory evidence, and the overall strength of the
    prosecution’s case.” 
    Carson, 870 F.3d at 597
    .
    No. 16-3845                                                  11
    We review for abuse of discretion because Groce had
    ample opportunity to impeach Stuhr on cross and through
    another witness. Groce impeached Stuhr on cross by raising
    her past drug use, past convictions, and flawed memory. He
    further challenged Stuhr’s credibility through the testimony
    of Brandy Eddy that Stuhr prostituted before meeting Groce.
    After all, Groce argues Eddy’s testimony casts significant
    doubt on the truthfulness of Stuhr’s testimony. Abuse of
    discretion is, of course, a highly deferential standard. We give
    special deference to evidentiary rulings “because of the trial
    judge’s first-hand exposure to the witnesses and the evidence
    as a whole, and because of the judge’s familiarity with the
    case and ability to gauge the impact of the evidence in the
    context of the entire proceeding.” United States v. Suggs, 
    374 F.3d 508
    , 516 (7th Cir. 2004) (citations omitted). A trial court
    abuses its discretion when “no reasonable person could take
    the view adopted by the trial court.” United States v. Cash, 
    394 F.3d 560
    , 564 (7th Cir. 2005). Here, given the other methods
    employed to impeach Stuhr, given the record as a whole, and
    given the requirements of Rule 412, the court did not abuse its
    discretion in barring Groce from crossing Stuhr on her alleged
    prostitution history.
    D. Sex-trafficking jury instruction
    Two states of mind support sex-trafficking: knowledge or
    reckless disregard. 18 U.S.C. § 1591(a). The court instructed
    the jury on the definition of “recklessly disregards”:
    As used in Counts 1, 2, 3 and 8, a person
    recklessly disregards a fact when he is aware of,
    but consciously or carelessly ignores, facts and
    circumstances that would reveal the fact that
    force, threats of force, or coercion would be
    12                                                          No. 16-3845
    used to cause another person to engage in a
    commercial sex act.
    (Jury Instr., Groce’s Separate App. at 77, emphasis in
    original.)
    Groce argues the court plainly erred by instructing the
    jury it could find he acted with reckless disregard if he
    carelessly ignored the relevant facts and circumstances. Groce
    argues this lowered the mens rea from criminal recklessness
    (which requires actual awareness of a substantial risk and
    conscious disregard of it) to mere negligence. He claims this
    plain error impaired his substantial rights because although
    he might have been careless, there is a reasonable probability
    a jury would not have found him reckless. 4 Groce’s main
    point is the instruction misstated the law by failing to require
    for conviction that he consciously disregarded the relevant
    facts and circumstances. He argues that because the court
    excluded evidence that he did not have the requisite mens rea
    for the offense (because he knew about the victims’ prior
    prostitution), and then lowered the mens rea with the
    erroneous instruction (allowing mere negligence to suffice),
    the court allowed the jury to convict him of sex trafficking
    without requiring proof of all elements.
    Normally we review de novo whether instructions
    accurately state the law, giving substantial discretion to the
    district court over the precise wording “so long as the final
    result, read as a whole, completely and correctly states the
    law.” Karahodzic v. JBS Carriers, Inc., 
    881 F.3d 1009
    , 1016 (7th
    4 Groce concedes the district court’s definition of “recklessly disregards”
    was based on a Committee Comment in our pattern jury instructions, but
    argues neither case cited in that comment supports the definition.
    No. 16-3845                                                   13
    Cir. 2018). But Groce did not object below to the instruction
    under Federal Rule of Criminal Procedure 30(d), so our
    review is limited to plain error. Fed. R. Crim. P. 30(d) and
    52(b); United States v. Cheek, 
    3 F.3d 1057
    , 1060 (7th Cir. 1993).
    He concedes and only requests plain-error review. “A plain
    error is not just one that is conspicuous but one whose
    correction is necessary to prevent a miscarriage of justice.”
    United States v. Kerley, 
    838 F.2d 932
    , 937 (7th Cir. 1988)
    (internal quotation marks omitted).
    But Groce arguably did more than merely forfeit his
    argument by not objecting; he arguably waived it by telling
    the district court he had no objection to the proposed
    instructions, which included the “or carelessly ignores”
    language. In United States v. Natale, 
    719 F.3d 719
    , 729–31 (7th
    Cir. 2013), we examined the important distinctions between
    passive forfeiture and affirmative waiver. A defendant who
    forfeits his argument by not objecting to an instruction before
    deliberation may attack that instruction on appeal only for
    plain error, but a defendant who waives his argument cannot
    even seek plain-error review. The problem sometimes is
    determining when waiver occurred. Waiver “occurs only
    when a defendant makes a knowing and intentional decision
    to forgo a challenge before the district court.” 
    Natale, 719 F.3d at 729
    (internal quotation marks omitted). We noted that
    “affirmative statements as simple as ‘no objection’ or ‘no
    problem’ when asked about the acceptability of a proposed
    instruction have resulted in waiver” because of the difficulty
    in determining the subjective motivations behind such
    statements. 
    Id. at 730.
    Since this approach can produce
    “especially harsh results,” we proposed alternative theories.

    theories because even under plain-error review, we found no
    error requiring a new trial there. 
    Id. at 731.
        So here. Even under plain-error review, we find no error
    requiring a new trial. Under plain-error review, we will
    reverse only for an obvious error that affects the defendant’s
    substantial rights and seriously impugns the fairness,
    integrity, or public reputation of judicial proceedings. Id.;
    United States v. Anderson, 
    604 F.3d 997
    , 1002 (7th Cir. 2010).
    The government concedes the instruction was wrong. Let us
    say it was obviously wrong, and should not have been given
    in any case. Still, Groce cannot show this error affected his
    substantial rights. That is, he cannot show a reasonable
    probability that but for the error the outcome would have
    differed, because overwhelming evidence demonstrated he
    did not merely recklessly disregard but he knew force, threats of
    force, and coercion were used to cause the victims to engage
    in commercial sex acts. Overwhelming evidence
    demonstrated he knew, and did not merely recklessly
    disregard, that his deliberate pattern of physical abuse,
    threats, and heroin control caused the victims to prostitute.
    For example, he confined Tischer to the Sparta house
    where she performed calls, not allowing her to leave without
    his permission. He controlled her heroin access, punished her,
    physically assaulted her, and burned her with a cigarette. He
    threatened her. He locked her inside the second residence
    several times. He forced her to prostitute. He also controlled
    Stuhr’s access to heroin. He manufactured debt for her,
    confiscated her phone, isolated her, and threatened her with
    a gun. He deprived her of heroin and even food until finally
    he asked if she was ready to take a call. He forced her to
    prostitute. He also controlled Ryan’s access to heroin. He

    insisted she engage in a commercial sex act to repay him for
    losing a debit card. He forced her to prostitute. The evidence
    against Groce is overwhelming. There is no reasonable
    probability the erroneous jury instruction changed the
    outcome.
    E. Copeland evidence
    The Copeland evidence was relevant to the charged
    conspiracy. Groce does not appeal that conviction but he does
    appeal the admission of this evidence due to risk of unfair
    prejudice on the sex-trafficking charges. Copeland and Groce
    were childhood friends, but he sandbagged her to prostitute,
    battered her, and took her money. He complains the court
    erred by admitting this evidence, which had minimal
    relevance and was cumulative of other conspiracy evidence.
    He claims the Copeland evidence was unfairly prejudicial
    because it created a substantial risk the jury would rely on it
    to decide his guilt on the sex-trafficking charges. He argues
    the evidence was disputed regarding whether the sex-
    trafficking victims prostituted voluntarily, but the
    government injected into the sad combination of bizarre and
    drug-infested relationships Copeland’s stark testimony,
    which might have persuaded the jury he was the type to sex-
    traffic. He argues the court should have barred it under Rule
    403.
    There is debate on the standard of review but under
    either plain-error or abuse-of-discretion, Groce loses. On
    abuse-of-discretion review we “defer to the district court
    unless no reasonable person could adopt its view.” United
    States v. Schmitt, 
    770 F.3d 524
    , 532 (7th Cir. 2014). Plain-error
    review requires an obvious error affecting Groce’s substantial
    rights and seriously impugning the fairness, integrity, or
    16                                                  No. 16-3845
    public reputation of judicial proceedings. 
    Natale, 719 F.3d at 731
    ; United States v. Klemis, 
    859 F.3d 436
    , 440–42, 445 (7th Cir.
    2017). That is, Groce must show a reasonable probability he
    would have been acquitted had the court barred this
    evidence. 
    Klemis, 859 F.3d at 445
    . Rule 403 allows barring if
    the “probative value is substantially outweighed by a danger
    of … unfair prejudice, confusing the issues, misleading the
    jury, undue delay, wasting time, or needlessly presenting
    cumulative evidence.” Fed. R. Evid. 403. But Groce loses his
    challenge because the Copeland evidence was direct evidence
    of the charged conspiracy. “We start with the premise that
    direct evidence of a crime is almost always admissible against
    a defendant.” United States v. Gorman, 
    613 F.3d 711
    , 717 (7th
    Cir. 2010). This was not merely evidence of other bad acts; this
    was direct evidence of a charged crime. He asks us to reweigh
    it on the Rule 403 scale and argues dangers of needless
    accumulation and unfair prejudice substantially outweigh its
    slight probative value. But we see no reason to disturb the
    court’s decision. The sex-trafficking evidence was
    overwhelming.
    F. Cumulative error
    Groce claims the cumulative effect of the errors denied
    him a fair trial on sex trafficking. Cumulative error exists
    where at least two errors committed during a trial denied
    defendant a fundamentally fair trial. United States v. Adams,
    
    628 F.3d 407
    , 419 (7th Cir. 2010); Alvarez v. Boyd, 
    225 F.3d 820
    ,
    824 (7th Cir. 2000). To demonstrate cumulative error, Groce
    must establish at least two errors occurred, and “considered
    together along with the entire record, the multiple errors so
    infected the jury’s deliberation that they denied [him] a
    fundamentally fair trial.” United States v. Allen, 
    269 F.3d 842
    ,
    No. 16-3845                                                           17
    847 (7th Cir. 2001). On a claim of cumulative error, we
    consider both—but only—plain or preserved errors. United
    States v. Christian, 
    673 F.3d 702
    , 708 (7th Cir. 2012). We only
    reverse if “the errors, considered together, could not have
    been harmless.” 
    Adams, 628 F.3d at 419
    .
    Here, no claimed errors warrant reversal of the sex-
    trafficking convictions as any errors were harmless.
    Overwhelming evidence proved he committed sex trafficking.
    The jury heard extensive testimony about his assaults, threats,
    and heroin control. He manipulated debt. He punished,
    isolated, and detained his victims. There is no reason to think
    any two or more potential errors combined to deprive him of
    a fundamentally fair trial. The record demonstrates his guilt
    “such that none of the asserted errors, either individually or
    cumulatively,” could have affected the verdict. 
    Id. at 420.
                               III. Conclusion
    We VACATE the conviction for witness retaliation and
    REMAND for resentencing. We AFFIRM the district court in
    all other respects. 5
    5 We close with a reminder that the jury convicted Groce on all but Count
    8 of nine counts. He appeals only the convictions on sex trafficking
    (Counts 1–3) and retaliation (Count 9). The 25-year sentence was for the
    convictions we affirm, the conviction we vacate, and the convictions he
    did not appeal.
