    OPINION
    GOULD, Circuit Judge:
    Alexander Lukashov, Jr. appeals his jury conviction for
    aggravated sexual abuse in violation of 18 U.S.C. § 2241(c).
    We have jurisdiction under 28 U.S.C. § 1291, and affirm.
    I
    A
    In February 2009, Alexander Lukashov, Jr., who worked as
    a long-haul truck driver in Portland, Oregon, was in a rela-
    11410            UNITED STATES v. LUKASHOV
    tionship with Cassedy Filer (“Cassedy”). Lukashov and
    Cassedy lived together with their two young children and
    Cassedy’s son and daughter from a previous marriage, J.F.
    and T.F. Her son J.F. was then six years old, and her daughter
    T.F. was eight. Before Lukashov’s departure on a long-haul
    trip to New York, Cassedy asked him to take J.F. to her rela-
    tives in Montana and to take T.F. along on the trip. Lukashov
    agreed, and he, J.F., and T.F. left Portland on February 5.
    Lukashov picked up a load in Washington, dropped J.F. off
    in Montana, and proceeded, with T.F. in his truck, to take his
    cargo to New York. He drove east to New York and delivered
    the Washington load there. He picked up another load in New
    York for delivery in Nevada. He then drove west with T.F.
    and delivered the New York load in Nevada. There he picked
    up still another load, destined for Portland. From Nevada, he
    drove west and north, and returned to Portland with T.F. on
    February 18.
    From the evidence introduced at trial, we see that Lukashov
    was doing more than just driving his long-haul truck with T.F.
    after he dropped J.F. off in Montana. Once returned to her
    home and mother, T.F. told a tale of serial sexual abuse by
    Lukashov as she traversed the country with him in his truck.
    Once Lukashov and T.F. had returned to her home, after
    Lukashov had left the house, T.F. told her mother that
    Lukashov had sexually abused her on the trip. T.F. described
    the abuse and showed her mother bruises that she said
    Lukashov had given her. When, a few days after T.F.’s return,
    the police came to the house to arrest Cassedy on an outstand-
    ing warrant, Cassedy reported the sexual abuse, and a police
    officer spoke to T.F. The police took a pair of T.F.’s under-
    wear and a pink blanket from the trip as potential evidence,
    and arrested Cassedy.
    Cassedy’s sister, Katie White, took T.F. to CARES North-
    west (“CARES”) for an examination. CARES is a medical
    clinic that specializes in child abuse and is part of a multi-
    UNITED STATES v. LUKASHOV              11411
    disciplinary child abuse team that is overseen by the district
    attorney’s office. Dr. Linda Lorenz is a pediatrician who eval-
    uates children for abuse and neglect at CARES. To evaluate
    a child, Lorenz does a medical examination and is assisted by
    an interviewer to gain more information pertinent to the
    child’s diagnosis and treatment.
    Together, Dr. Lorenz and Rachel Petke, a social worker at
    CARES, evaluated T.F. Lorenz conducted a physical exami-
    nation of T.F. T.F.’s genital exam and anal exam were nor-
    mal, but Lorenz found “abnormal” bruises on the inside of
    one knee and on the side of T.F.’s left hip. Lorenz asked T.F.
    why her aunt had brought her to CARES. T.F. said that she
    had gone on a trip with her “dad” and J.F. and that on the trip
    Lukashov had anally penetrated her and had tried to vaginally
    penetrate her but “couldn’t.” T.F. described the abuse to
    Lorenz in the language of an eight-year-old, saying, for exam-
    ple, that Lukashov had put his “private part” in “the part
    where the poop comes out” and that he had tried to put it in
    her “crotch.” Lorenz also asked T.F. about the bruises on her
    body. T.F. said that she got the bruise on her knee from
    Lukashov after he made her take off her pants and underwear
    and get on her hands and knees, and that she got the bruise
    on her hip from Lukashov grabbing her hip and “going really
    fast.” T.F. added that there had been a bruise on her other hip
    that had faded.
    After the physical examination, Petke interviewed T.F. The
    interview was videotaped, and Dr. Lorenz and a police officer
    observed it through a mirror. T.F. gave Petke a more detailed
    account of the sexual abuse than she gave Lorenz. T.F. said
    that the abuse happened after J.F. was dropped off in Montana
    and that it happened more than once, in Montana, North
    Dakota, and Nevada. T.F. said that the abuse took place in the
    semi-truck and in a hotel room in Nevada. T.F. told Petke, as
    she had Lorenz, that Lukashov had anally penetrated her and
    that he had tried unsuccessfully to vaginally penetrate her.
    She also said that Lukashov had made her perform oral sex
    11412             UNITED STATES v. LUKASHOV
    on him and ejaculated in her mouth. T.F. gave age-appropriate
    descriptions, saying, for example, that Lukashov had tried to
    “shove it in [her] porcupine” and that when Lukashov put his
    “private part” in her mouth, “white stuff” that tasted “[l]ike
    foamy” had come out.
    B
    Lukashov was charged with aggravated sexual abuse in
    violation of 18 U.S.C. § 2241(c) (Count 1), travel with intent
    to engage in illicit sexual contact in violation of 18 U.S.C.
    § 2423(b) (Count 2), and transportation with intent to engage
    in criminal sexual activity in violation of 18 U.S.C. § 2423(a)
    (Count 3). Lukashov pleaded not guilty.
    The district court ruled on several evidentiary matters
    before trial. Lukashov had moved to exclude T.F.’s state-
    ments to Dr. Lorenz and Rachel Petke at CARES, and the dis-
    trict court denied this motion. Lukashov also had moved in
    limine to admit evidence of prior acts of Cassedy Filer to
    show that she had a pattern of making false allegations against
    her partner in a relationship. The district court ruled that
    Lukashov could offer opinion or reputation evidence of
    Cassedy’s bad character for truthfulness but not evidence of
    specific prior acts. The district court held a Daubert hearing
    on the proposed testimony of Dr. Lorenz about characteristics
    of child sex abuse victims, and then held that Lorenz could
    testify about characteristics that she looks for in child sex
    abuse victims and that T.F.’s physical examination and state-
    ments during the CARES evaluation were consistent with her
    allegations of sexual abuse.
    The trial by jury lasted five days, and resulted in
    Lukashov’s conviction. T.F. testified at trial, and the district
    court also admitted the video of her interview with Rachel
    Petke, giving the jury two opportunities to hear T.F.’s version
    of events. Dr. Lorenz described T.F.’s CARES evaluation,
    explained that child victims of sexual abuse can have normal
    UNITED STATES v. LUKASHOV                   11413
    genital and anal exams several days after the abuse, and testi-
    fied that her physical findings and observations of T.F. were
    consistent with T.F.’s allegations of sexual abuse. Forensic
    scientist Amy Wilson testified that she found spermatozoa on
    fabric cuttings from the interior crotch and interior seat areas
    of T.F.’s underwear given to the police, and that the DNA
    profile of the spermatozoa matched Lukashov’s DNA profile.
    No seminal fluid was found on the underwear, however, and
    no spermatozoa or seminal fluid was found on the pink blan-
    ket.
    Lukashov testified in his own defense, and denied any
    abuse. An important part of Lukashov’s theory of defense was
    his allegation that Cassedy had coached T.F. into making
    false allegations against him because Cassedy wanted to gain
    a tactical advantage in the pending breakup of their relation-
    ship. Lukashov testified that after returning from the trip with
    T.F., he told Cassedy more than once that their relationship
    was over, that Cassedy asked him to come back, but that in
    his mind, it was over.
    On the third day of trial, at the close of the government’s
    case-in-chief, Lukashov moved for a judgment of acquittal on
    the ground of improper venue. The parties disagreed about
    whether venue was a fact issue for the jury or a question of
    law for the court and whether venue existed under either or
    both paragraphs of the applicable venue statute, 18 U.S.C.
    § 3237(a). The district court recognized our precedent that
    normally it is not for the court to determine venue and that it
    is error to not give a requested instruction on venue.1 The dis-
    trict court denied Lukashov’s motion because it concluded
    that the government’s evidence, if credited by the jury, was
    sufficient to show venue under either paragraph of § 3237(a).
    Because of the varying theories on which venue might be
    based, the district court decided to submit venue to the jury
    on each of the possible theories urged by the government, “in
    1
    See United States v. Casch, 
    448 F.3d 1115
    , 1117 (9th Cir. 2006).
    11414             UNITED STATES v. LUKASHOV
    an effort to minimize any need for the child victim to testify
    again in any retrial ordered because of the venue issues.”
    Lukashov also moved for a judgment of acquittal for insuf-
    ficient evidence of purpose on all three counts, and the district
    court denied this motion as well.
    The district court instructed the jury on the elements of
    each of the charged crimes, and gave the following instruction
    on venue:
    In addition to its burden to prove every element of
    each of the Counts against the Defendant beyond a
    reasonable doubt, as I am about to instruct you, the
    government must also prove by a preponderance of
    the evidence:
    1.   that the offense began, continued, or
    was completed within the District of
    Oregon; and/or
    2.   that the offense involved a form of
    transportation across state lines from,
    through, or into the District of Oregon;
    and/or
    3.   that the offense involved transporting a
    person from, through, or into the Dis-
    trict of Oregon.
    The jury found Lukashov guilty on Count 1 and not guilty
    on Count 2; it did not reach a verdict on Count 3. The jury
    returned a special verdict finding that the government did not
    prove by a preponderance of the evidence that the offense
    charged in Count 1 (1) “began, continued, or was completed
    within the District of Oregon,” but that the government never-
    theless proved venue by a preponderance of the evidence
    because the offense (2) “involved a form of transportation
    UNITED STATES v. LUKASHOV                      11415
    across state lines from, through, or into the District of Ore-
    gon” and (3) “involved transporting a person from, through,
    or into the District of Oregon.”
    Lukashov filed post-trial motions for judgment of acquittal
    based on insufficient evidence of purpose and improper
    venue. The district court denied both motions. On Lukashov’s
    challenge to the sufficiency of the evidence, the district court
    applied the traditional standard of Jackson v. Virginia, 
    443 U.S. 307
    , 319 (1979), and concluded that viewing the evi-
    dence in the light most favorable to the government, which
    had gained the jury’s verdict, the “purpose” element of aggra-
    vated sexual abuse had been proved beyond a reasonable
    doubt.
    With regard to venue, the district court first noted that
    venue in a criminal case had to be shown by a preponderance
    of the evidence. The district court then held that venue was
    proper on two alternative grounds, based respectively on the
    first and second paragraphs of 18 U.S.C. § 3237(a). We
    address only the first paragraph of § 3237(a) and whether
    Lukashov’s sexual abuse of T.F. was a continuing offense that
    was begun, continued, or completed in the District of Oregon.2
    On this the district court reasoned:
    In hindsight, the Court believes its venue instruc-
    2
    The district court held that venue was proper under the second para-
    graph of § 3237(a) because the jury had found that the offense involved
    interstate transportation from, through, or into the District of Oregon, sat-
    isfying subparagraph (2) of the jury instruction on venue. In ruling on
    Lukashov’s post-trial motions for judgment of acquittal, the district court
    concluded that its instruction in subparagraph (3), based on an alternative
    “interstate commerce” theory, that venue was proper if “the offense
    involved transporting a person from, through, or into the District of Ore-
    gon,” was error. The district court held that the jury’s affirmative finding
    on this alternative theory should be disregarded. Because we resolve
    Lukashov’s venue challenge based on the first paragraph of § 3237(a), we
    do not reach these issues.
    11416            UNITED STATES v. LUKASHOV
    tions to the jury did not give sufficient guidance
    about the alternate venue theories on which the gov-
    ernment was proceeding after these venue issue[s]
    arose during trial. As to Count 1, the Court likely
    should have instructed the jury that if it found
    Defendant guilty and thereby found as fact that
    Defendant crossed a state line with the intent to
    engage in the requisite sexual act with T.F. and that
    Defendant then knowingly engaged in that sexual act
    with T.F., then the offense was, as a matter of law,
    a “continuing offense” (under the first paragraph of
    § 3237(a)) because the offense was completed in the
    District of Oregon when Defendant returned this
    eight-year old victim to her home. When the jury
    found beyond a reasonable doubt the facts necessary
    to convict the Defendant on Count 1, the Court now
    concludes there were not any additional facts for the
    jury to find as to venue under United States v.
    
    Casch[, 448 F.3d at 1117
    ] before the Court should
    have determined venue was established on this the-
    ory as a matter of law under United States v.
    [Angotti, 
    105 F.3d 539
    , 541 (9th Cir. 1997)] and
    United States v. Childs[, 
    5 F.3d 1328
    , 1331 (9th Cir.
    1993)]. In other words, when the government proved
    the substantive elements of Count 1 beyond a rea-
    sonable doubt, it necessarily proved by a preponder-
    ance of the evidence the factual predicate for a legal
    determination that Defendant’s ongoing sexual abuse
    of T.F. was a continuing offense because it began
    sometime after T.F.’s brother was left in Montana
    but before Defendant carried his commercial load to
    New York, continued specifically through Nevada
    during the trip back to Oregon, and ended when the
    Defendant completed the trip and returned this minor
    child who was in his physical custody and control to
    the District of Oregon. In addition, finding that
    venue in Oregon is proper under the first prong of
    § 3237(a) is consistent with general policy consider-
    UNITED STATES v. LUKASHOV               11417
    ations behind venue provisions; i.e., conducting the
    trial in a place convenient to the parties and the wit-
    nesses, all of whom in this cases were from Oregon
    when the child victim was unable to pinpoint geo-
    graphically all of the places along the trip where
    Defendant abused her.
    Although the Court respects and understands the
    jury’s finding on this venue issue, the Court now
    concludes the issue as to the first prong [of]
    § 3237(a) became a question of law when the jury
    found Defendant guilty of Count 1. Thus, to the
    extent the Court has the authority to determine venue
    was established under the first prong of § 3237(a) as
    a matter of law at this post-verdict stage, it now
    does.
    The district court sentenced Lukashov to 30 years in cus-
    tody and entered judgment. Lukashov timely appealed. He
    raises issues on several evidentiary rulings, on the sufficiency
    of the evidence to convict him of aggravated sexual abuse,
    and on whether venue was proper in the District of Oregon.
    We review the issues in this order because the admissibility
    of evidence bears on the larger issue of the sufficiency of the
    evidence, and because the sufficiency of the evidence on
    Lukashov’s sexual abuse of T.F. relates to the venue issue of
    whether that offense began, continued, or was completed in
    Oregon.
    II
    We first address the evidence issues. We review the district
    court’s evidentiary rulings for abuse of discretion and its
    underlying factual determinations for clear error. See United
    States v. Shyrock, 
    342 F.3d 948
    , 981 (9th Cir. 2003).
    Lukashov challenges the district court’s admission of T.F.’s
    videotaped interview with Rachel Petke, contending that
    11418             UNITED STATES v. LUKASHOV
    T.F.’s statements to Petke were not made for purposes of
    medical diagnosis or treatment and should have been
    excluded as inadmissible hearsay.
    Before trial, the district court held an evidentiary hearing
    on the admissibility of T.F.’s statements to Dr. Lorenz and
    Petke at CARES. At the hearing Lorenz explained that the
    physical exam and interview “go hand-in-hand in generating
    a medical diagnosis,” and Petke similarly said that the pur-
    pose of the interview was “to gather information to be used
    in determining the diagnosis that the physician makes and to
    make treatment recommendations.” In addition, Lorenz testi-
    fied that before she examined T.F., she told T.F. that CARES
    was “a regular doctor’s office,” that she and Petke worked
    together as a “team”—she was the “doctor” and Petke was the
    “talking person,” and that together they were going to make
    sure that T.F. was healthy. The district court found that T.F.’s
    statements to Petke were made for purposes of medical diag-
    nosis and treatment and admitted the video of T.F.’s interview
    with Petke under Federal Rule of Evidence 803(4). See Fed.
    R. Evid. 803(4)(A) (excepting from hearsay rule statements
    that are “made for—and [are] reasonably pertinent to—
    medical diagnosis or treatment”).
    Lukashov argues that the purpose of T.F.’s statements to
    Petke was to build a case against him rather than to obtain
    medical diagnosis or treatment. Lukashov relies upon, among
    other things, the interview’s removal from the medical exami-
    nation setting, the observation of the interview by a police
    officer, and T.F.’s use of the word “evidence” during the
    interview.
    [1] We are not persuaded that the district court’s finding
    on the purpose of T.F.’s statements was clearly erroneous. See
    Fed. R. Evid. 104(a); 
    Shyrock, 342 F.3d at 981
    . Because
    “[s]exual abuse involves more than physical injury,” in cases
    such as this one statements “made for purpose[s] of physical
    or non-physical treatment and diagnosis” may be admitted
    UNITED STATES v. LUKASHOV                11419
    under Rule 803(4). See Guam v. Ignacio, 
    10 F.3d 608
    , 613
    (9th Cir. 1993) (internal quotation marks and citation omit-
    ted). That T.F.’s interview with Petke was separate from her
    physical exam with Dr. Lorenz is immaterial; what matters is
    that, to T.F., Petke, and Lorenz, the interview took place for
    the purpose of, and was reasonably pertinent to, medical diag-
    nosis and treatment. See Fed. R. Evid. 803(4); 
    Ignacio, 10 F.3d at 613
    & n.3. The district court reasonably concluded (1)
    that T.F. understood the “whole evaluation” to be part of “a
    medical process, something that she was brought to partici-
    pate in for purposes of determining her safety and to ensure
    that she would be protected and would be treated if she
    needed help,” and (2) that Petke and Lorenz viewed the two
    parts of the process as “inextricably intertwined and part of
    the same diagnostic undertaking.” The district court also rea-
    sonably credited Petke’s and Lorenz’s testimony that the pres-
    ence of law enforcement did not change the medical nature of
    their evaluation of T.F. Finally, T.F.’s references to “evi-
    dence” do not make the videotaped interview inadmissible,
    because they were brief, not prompted or followed up on by
    Petke, and tangential to T.F.’s description of the sexual abuse
    for medical examination purposes.
    [2] The district court did not abuse its discretion in admit-
    ting Petke’s interview of T.F. under Rule 803(4).
    III
    Lukashov contends that the district court erred in admitting
    Dr. Lorenz’s testimony that her observations of T.F. and
    T.F.’s statements were consistent with T.F.’s allegations of
    sexual abuse.
    [3] Federal Rule of Evidence 702 governs the admissibility
    of expert opinion testimony. Rule 702 in broad language
    requires that the testimony “help the trier of fact to understand
    the evidence or to determine a fact in issue” and that the
    expert be sufficiently qualified to give the opinion. Fed. R.
    11420             UNITED STATES v. LUKASHOV
    Evid. 702; Primiano v. Cook, 
    598 F.3d 558
    , 563 (9th Cir.
    2010). Expert testimony should be excluded “if it concerns a
    subject improper for expert testimony, for example, one that
    invades the province of the jury.” United States v. Binder, 
    769 F.2d 595
    , 602 (9th Cir. 1985), overruled on other grounds by
    United States v. Morales, 
    108 F.3d 1031
    , 1035 (9th Cir. 1997)
    (en banc).
    The district court permitted Dr. Lorenz to testify about four
    general characteristics that she looks for in determining
    whether a child has been sexually abused: (1) spontaneous
    detail, (2) sexual knowledge, (3) sensory detail, and (4) age-
    appropriate language. In ruling this testimony admissible, the
    district court explained that Lorenz could “provide the jury
    with material that is beyond their general knowledge, specifi-
    cally with respect to the idea that there are age-appropriate
    behaviors and language, age-appropriate capacities concern-
    ing knowledge around sex, that are significant to a pediatri-
    cian in her role.” The district court also let Lorenz give her
    opinion that T.F.’s medical exam and statements during the
    evaluation were consistent with her allegations of sexual
    abuse. The district court limited its ruling by cautioning that
    Lorenz could “not be asked any question that call[ed] for her
    to comment on either explicitly or implicitly the inherent
    credibility of [T.F.] as a witness.”
    [4] Lukashov argues that Dr. Lorenz’s testimony improp-
    erly bolstered T.F.’s credibility. He cites United States v.
    Binder, in which we held that expert testimony that the child
    victim-witnesses could distinguish fantasy from reality and
    truth from falsehood improperly “bolster[ed] the children’s
    story” and “usurp[ed] the jury’s fact-finding 
    function.” 769 F.2d at 602
    . The government argues that Lorenz’s testimony
    was not improper because it was helpful to the jury and con-
    cerned general characteristics of child sex abuse victims
    rather than the credibility of T.F. in particular. See United
    States v. Hadley, 
    918 F.2d 848
    , 852-53 (9th Cir. 1990) (hold-
    ing that expert testimony about characteristics of “a class of
    UNITED STATES v. LUKASHOV                11421
    victims generally” not improper bolstering (internal quotation
    marks and citation omitted)); see also United States v. Big-

    (holding testimony improper
    because “experts testified that these particular children in this
    particular case could be believed”). The government also
    urges us to follow the Eighth Circuit’s approach in United
    States v. Whitted, where the court held that an expert permis-
    sibly “express[ed] his opinion that his medical findings were
    consistent with [the child]’s claims of sexual abuse.” 
    11 F.3d 782
    , 786 (8th Cir. 1993); see also United States v. Charley,
    
    189 F.3d 1251
    , 1265-65 (10th Cir. 1999) (concluding that dis-
    trict court did not abuse its discretion in allowing doctor to
    “ ‘summarize the medical evidence and express an opinion
    that the evidence is consistent or inconsistent with the vic-
    tim’s allegations of sexual abuse’ ” (quoting 
    Whitted, 11 F.3d at 785
    )).
    [5] In our view, the government has the better of this argu-
    ment. We conclude that the district court did not abuse its dis-
    cretion in allowing Dr. Lorenz to testify about the
    characteristics that she looks for when assessing a child vic-
    tim’s story of sexual abuse, and to opine that her evaluation
    of T.F. was consistent with T.F.’s allegations of sexual abuse.
    Lorenz’s testimony was helpful to the jury because some
    jurors would not have a general understanding of an eight-
    year-old’s sexual knowledge and vocabulary and the level of
    sensory detail to look for in a child’s allegations of sexual
    abuse. See Fed. R. Evid. 702(a). By giving her opinion that
    her medical findings and observations were consistent with
    T.F.’s allegations of sexual abuse, Lorenz permissibly applied
    her expertise to aid the jury in understanding the evidence.
    See 
    Whitted, 11 F.3d at 786
    ; 
    Antone, 981 F.2d at 1062
    . Her
    testimony was limited and did not invade the jury’s fact-
    finding function, as she did not comment on T.F.’s credibility
    or state a diagnosis to the jury. See 
    Whitted, 11 F.3d at 786
    11422              UNITED STATES v. LUKASHOV
    (holding that doctor’s diagnosis of child sexual abuse “went
    too far”).
    IV
    [6] On another evidence ruling, Lukashov challenges the
    district court’s admission of Katie White’s testimony that T.F.
    had a truthful character. Federal Rule of Evidence 608(a)
    states that a witness’s credibility may be supported by opinion
    testimony about the witness’s character for truthfulness, but
    that “evidence of truthful character is admissible only after
    the witness’s character for truthfulness has been attacked.”
    We have said that Rule 608(a) “permits rehabilitation after
    indirect attacks on a witness’s general character for truthful-
    ness” but “prohibits rehabilitation by character evidence of
    truthfulness after direct attacks on a witness’s veracity in the
    instant case.” United States v. Dring, 
    930 F.2d 687
    , 691 (9th
    Cir. 1991). “It is for the trial court, exercising its discretion,
    to determine whether given conduct constitutes a direct or
    indirect attack on a witness’s character for truthfulness.” 
    Id. [7] Lukashov contends
    that White’s opinion testimony on
    T.F.’s truthful character was not admissible because T.F.’s
    character for truthfulness had not been attacked. We disagree.
    Lukashov’s defense stressed that T.F. was lying because her
    mother told her to lie, that she not only lied on the witness
    stand at trial, but had been lying from the beginning, to the
    police and to Dr. Lorenz and to Rachel Petke. Lukashov did
    not merely point out inconsistencies in T.F.’s trial testimony.
    Rather, he focused his defense, from opening statement
    through closing argument, on calling T.F. a liar. As it appears
    to us, the defense argument carried “ ‘strong accusations of
    misconduct and bad character’ ” of T.F., which the district
    court thought in fairness permitted evidence of her good char-
    acter and truthfulness. See 
    id. at 692 (quoting
    McCormick on
    Evidence); 1 McCormick on Evidence § 47 (6th ed. 2009)
    (stating that the greater the number of inconsistencies brought
    out in cross-examination, “the stronger is the inference that by
    UNITED STATES v. LUKASHOV                      11423
    character the witness is a liar, not simply a witness who has
    told an isolated lie”). Though this evidence ruling presents a
    close question, we hold that the district court did not abuse its
    discretion when it responsively admitted White’s testimony
    on T.F.’s truthful character.3
    V
    Lukashov’s final evidentiary contention is that the district
    court improperly excluded evidence of Cassedy Filer’s
    alleged prior acts. Lukashov alleged that Cassedy made false
    allegations of assault against her ex-husband, Merlin Filer,
    and then threatened to take their children to force him to plead
    guilty, and that she tried to plant false memories in T.F. of
    Merlin trying to drown her in the bathtub and burn her with
    a cigarette. Lukashov sought to introduce evidence of these
    acts to support his theory that Cassedy had coached T.F. into
    making false allegations of sexual abuse against him.
    [8] The district court excluded this evidence under Federal
    Rule of Evidence 404(b). Lukashov argues that he offered the
    evidence for a permissible purpose, to show a “pattern” in
    Cassedy’s conduct, of fabricating allegations against her part-
    ner and involving her children in the allegations. But by intro-
    ducing Cassedy’s past pattern of conduct, Lukashov would
    have been asking the jury to engage in propensity reasoning
    along these lines: Cassedy had engaged in prior bad acts by
    using her children against Merlin in past disputes, so it was
    likely that she was using T.F. against Lukashov in this case.
    In our view, Rule 404(b) prohibits this sort of propensity evi-
    dence, and Lukashov’s reasoning does not bring the prior bad
    3
    Moreover, even if there was error in admitting White’s testimony about
    T.F.’s truthful character, we would consider it harmless in the context of
    this case, in which there was direct testimony of T.F. at trial and by video,
    direct testimony of Lukashov, physical evidence of bruises on T.F. and
    spermatozoa matching Lukashov’s DNA profile on her underwear, and
    expert testimony that T.F.’s medical exam and statements were consistent
    with her allegations of sexual abuse.
    11424              UNITED STATES v. LUKASHOV
    acts evidence within any of the uses permitted by Rule 404(b)
    for prior bad acts evidence, “such as motive, opportunity,
    intent, preparation, plan, knowledge, identity, absence of mis-
    take, or lack of accident.” In any event, even if the matter is
    fairly arguable, the district court’s excluding this evidence of
    Cassedy’s past conduct related to Merlin Filer was not an
    abuse of discretion.
    VI
    We next turn to Lukashov’s challenge to the sufficiency of
    the evidence. In reviewing a challenge to the sufficiency of
    the evidence to support a verdict in a criminal case, we ask
    “whether, after viewing the evidence in the light most favor-
    able to the prosecution, any rational trier of fact could have
    found the essential elements of the crime beyond a reasonable
    doubt.” 
    Jackson, 443 U.S. at 319
    . This standard is highly def-
    erential because our criminal justice system gives primacy to
    the role of the jury in determining guilt beyond a reasonable
    doubt after being correctly instructed on the governing law.
    [9] Lukashov contends that the evidence at trial was insuf-
    ficient because it did not establish that he had the requisite
    purpose for conviction under 18 U.S.C. § 2241(c). His posi-
    tion is that because his purpose in traveling to New York and
    back to Oregon was to pick up and deliver goods in his capac-
    ity as a long-haul truck driver, and because it was Cassedy
    Filer’s rather than his idea for T.F. to go on the trip, no ratio-
    nal juror could have found that his purpose in crossing a state
    line was to engage in a sexual act with T.F. This contention
    is without merit, and ignores the human ability and propensity
    to act in light of multiple motives and purposes.
    The district court instructed the jury that to convict
    Lukashov on Count 1, the government had to prove beyond
    a reasonable doubt that he “traveled across a state line with
    the intent to engage in a sexual act with T.F.,” and explained:
    UNITED STATES v. LUKASHOV               11425
    [T]he government need not prove that the Defendant
    traveled across a state line for the sole and exclusive
    purpose of engaging in a sexual act. A person may
    have different purposes or motives for travel and
    each may prompt in varying degrees the act of mak-
    ing the journey. For purposes of [this element], the
    government must prove beyond a reasonable doubt
    that a dominant, significant, or motivating purpose
    of Defendant’s travel across a state line was to
    engage in a sexual act with T.F. In other words, the
    government must prove the sexual act was not
    merely incidental to the travel.
    [10] Viewed in the light most favorable to the government,
    the evidence showed that Lukashov engaged in abhorrent sex-
    ual acts with T.F. in three different states, Montana, North
    Dakota, and Nevada. A rational jury could have found beyond
    a reasonable doubt that once Lukashov formed the intent to
    sexually abuse T.F., whether that occurred before he started
    the trip or only after he dropped off J.F. in Montana and was
    alone in his truck with T.F., he had that illicit intent for the
    rest of the trip, until he returned her to her mother in Portland.
    Given the repeated instances of abuse after the first time in
    Montana, a jury could rationally infer that Lukashov crossed
    the Montana-North Dakota and subsequent state lines with “a
    dominant, significant, or motivating purpose” of committing
    additional sexual acts. That Lukashov also had a commercial
    purpose for crossing state lines does not negate the inference
    that he had a significant or motivating purpose to continue
    abusing T.F. because, as the district court correctly instructed
    the jury, the government did not have to prove that sexually
    abusing T.F. was the sole purpose of Lukashov’s interstate
    travel. See United States v. Cryar, 
    232 F.3d 1318
    , 1324 (10th
    Cir. 2000) (rejecting defendant’s insufficient evidence argu-
    ment that “the dominant purpose of his crossing the state line
    from Texas to Oklahoma was to earn a living, and not to com-
    mit a sexual act”). It also does not matter that Cassedy rather
    than Lukashov first suggested that T.F. go on the trip, so long
    11426              UNITED STATES v. LUKASHOV
    as Lukashov committed each element of § 2241(c) thereafter.
    On the element of purpose, the Supreme Court’s standard in
    Jackson v. Virginia was amply satisfied here. 
    See 443 U.S. at 319
    .
    VII
    We finally address Lukashov’s challenge to venue. We
    review the district court’s determination on venue de novo.
    United States v. Arango, 
    670 F.3d 988
    , 992 (9th Cir. 2012).
    [11] Proper venue is not a mere technicality. Instead, a
    defendant in a criminal case has a constitutional right to be
    tried in a district where the crime was committed. U.S. Const.
    art. III, § 2, cl. 3 (“The Trial of all Crimes . . . shall be held
    in the State where the said Crimes shall have been commit-
    ted.”); 
    id. amend. VI (“In
    all criminal prosecutions, the
    accused shall enjoy the right to a speedy and public trial, by
    an impartial jury of the State and district wherein the crime
    shall have been committed . . . .”). This constitutional require-
    ment is also implemented explicitly in the Federal Rules of
    Criminal Procedure. See Fed. R. Crim. P. 18 (“Unless a stat-
    ute or these rules permit otherwise, the government must
    prosecute an offense in a district where the offense was com-
    mitted.”).
    We have previously explained:
    Our venue law grows out of important concerns that
    a criminal jury trial be held near the place where the
    crime was committed and where prosecution can
    conveniently proceed. “In criminal cases venue
    involves important considerations of policy, with
    deep historical roots, that are now expressed in a
    complicated interplay of constitutional provisions,
    statutes and rules.” The Supreme Court has, at vari-
    ous times, expounded on the importance of prosecut-
    ing cases near the criminal defendant’s home. On
    UNITED STATES v. LUKASHOV                  11427
    other occasions, the Court has stressed the impor-
    tance of a trial at the locus of the crime.
    ....
    Determining where an offense was committed, how-
    ever, has often been a sticky question. Many
    offenses, like complex conspiracies or transporting
    contraband, may continue through multiple venues.
    Congress has eased the burden of answering this
    question by providing [in 18 U.S.C. § 3237(a)] that
    continuing offenses may be prosecuted where they
    are begun, continued, or completed[.]
    
    Angotti, 105 F.3d at 541-42
    (citations omitted).
    The general rules controlling this sphere of law are well
    settled: Venue is a question of fact that the government must
    prove by a preponderance of the evidence. 
    Casch, 448 F.3d at 1117
    ; United States v. Pace, 
    314 F.3d 344
    , 349 (9th Cir.
    2002). In a jury trial, it is for the jury, not the court, “to deter-
    mine that venue exists,” and “it is error for the court to
    decline to give [an] instruction [on venue],” if properly
    requested. 
    Casch, 448 F.3d at 1117
    . The sufficiency of the
    evidence to justify a finding on venue, by contrast, is a ques-
    tion of law for the court. See 2 Charles Alan Wright et al.,
    Federal Practice & Procedure § 307 (4th ed. 2011); see also
    
    Angotti, 105 F.3d at 541
    .
    [12] On the other hand, the unusual circumstances of this
    case, where the district court first gave an instruction on
    venue and then, after the jury’s determination of guilt beyond
    a reasonable doubt in substance, decided the venue question
    of when the crime was completed as a matter of law, require
    us to take a fresh look at the governing principles. We have
    found no prior precedent holding that the evidence in a case
    permitted the trial court, as the district court did here, to take
    the venue issue from the jury and determine it as a matter of
    11428              UNITED STATES v. LUKASHOV
    law. However, we formulate the following rule to be applied:
    Where a rational jury could not fail to conclude that a prepon-
    derance of the evidence establishes venue, then a court is jus-
    tified in determining venue as a matter of law. Precedent
    supports the idea that when a court has failed to give a venue
    instruction to the jury, that error will be viewed as harmless
    if the evidence viewed rationally by a jury could only support
    a conclusion that venue existed. E.g., United States v. Miller,
    
    111 F.3d 747
    , 751-53 (10th Cir. 1997); see also 
    Casch, 448 F.3d at 1117
    -18; United States v. Massa, 
    686 F.2d 526
    , 531
    (7th Cir. 1982). It follows logically that, having given a venue
    instruction, as the district court did here, if the evidence could
    only be viewed by a rational jury as sustaining venue by a
    preponderance of the evidence, which the district court con-
    cluded was the case once the jury found the elements of 18
    U.S.C. § 2241(c) beyond a reasonable doubt, then a court can
    take the venue issue from the jury and decide it as a matter
    of law.
    To decide whether venue is proper in a district, we “must
    initially identify the conduct constituting the offense (the
    nature of the crime) and then discern the location of the com-
    mission of the criminal acts.” United States v. Rodriguez-
    Moreno, 
    526 U.S. 275
    , 279 (1999). “To determine the ‘nature
    of the crime,’ we look to the ‘essential conduct elements’ of
    the offense.” 
    Pace, 314 F.3d at 349
    (quoting Rodriguez-
    
    Moreno, 526 U.S. at 280
    ). For continuing offenses, 18 U.S.C.
    § 3237(a) states:
    Except as otherwise expressly provided by enact-
    ment of Congress, any offense against the United
    States begun in one district and completed in
    another, or committed in more than one district, may
    be inquired of and prosecuted in any district in
    which such offense was begun, continued, or com-
    pleted.
    Any offense involving the use of the mails, transpor-
    tation in interstate or foreign commerce, or the
    UNITED STATES v. LUKASHOV                11429
    importation of an object or person into the United
    States is a continuing offense and, except as other-
    wise expressly provided by enactment of Congress,
    may be inquired of and prosecuted in any district
    from, through, or into which such commerce, mail
    matter, or imported object or person moves.
    [13] Under Rodriguez-Moreno and § 3237(a), venue for a
    continuing offense is proper if an “essential conduct element”
    of the offense begins in, continues into, or is completed in the
    charging district. 18 U.S.C. § 3237(a); Rodriguez-
    Moreno, 526 U.S. at 280
    ; United States v. Stinson, 
    647 F.3d 1196
    ,
    1204 (9th Cir. 2011). Because Lukashov was convicted of
    aggravated sexual abuse in violation of 18 U.S.C. § 2241(c),
    we identify the “essential conduct elements” of aggravated
    sexual abuse. See 
    Rodriguez-Moreno, 526 U.S. at 279-80
    .
    Section 2241(c) states:
    Whoever crosses a State line with intent to engage in
    a sexual act with a person who has not attained the
    age of 12 years, . . . knowingly engages in a sexual
    act with another person who has not attained the age
    of 12 years, . . . or attempts to do so, shall be fined
    under this title and imprisoned for not less than 30
    years or for life.
    [14] The essential conduct elements are (1) crossing a state
    line, (2) with intent to engage in a sexual act with a child, and
    (3) engaging in or attempting to engage in a sexual act with
    a child. See 
    Cryar, 232 F.3d at 1322
    . Given the continuing
    nature of these elements, the district court correctly held, and
    the parties do not dispute, that aggravated sexual abuse is a
    continuing offense for purposes of 18 U.S.C. § 3237(a). See
    
    id. We next “discern
    the location of the commission of the
    criminal acts.” 
    Rodriguez-Moreno, 526 U.S. at 279
    . On this
    issue, the parties disagree. As we explained above, the district
    11430              UNITED STATES v. LUKASHOV
    court held, notwithstanding the jury’s finding that the offense
    in Count 1 did not begin, continue, or end in the District of
    Oregon, that venue was proper under the first paragraph of
    § 3237(a). The district court reasoned that once the jury found
    that the government had proved the substantive elements of
    Count 1 beyond a reasonable doubt, the government had nec-
    essarily proved by a preponderance of the evidence that
    Lukashov’s sexual abuse of T.F. was a continuing offense that
    started after her brother J.F. was left in Montana, continued
    as Lukashov drove to New York and back through Nevada,
    and ended when Lukashov returned T.F. to her home in Port-
    land, Oregon. The district court thus concluded that when the
    jury found Lukashov guilty on Count 1, venue became a ques-
    tion of law and the government had proved venue “as a matter
    of law.”
    Lukashov contends that we must accept the jury’s finding
    that the offense of aggravated sexual abuse did not begin,
    continue, or end in the District of Oregon. He argues that
    venue was not proper under the first paragraph of § 3237(a)
    because no “essential conduct element” of aggravated sexual
    abuse began, continued, or was completed in the District of
    Oregon. See Rodriguez-
    Moreno, 526 U.S. at 280
    .
    We have previously said that a continuing offense “does
    not terminate merely because all of the elements are met.”
    United States v. Lopez, 
    484 F.3d 1186
    , 1192 (9th Cir. 2007)
    (en banc). It is committed “over the whole area through which
    force propelled by an offender operates.” United States v.
    Johnson, 
    323 U.S. 273
    , 275 (1944).
    [15] Whenever precisely Lukashov formed his intent to
    abuse T.F., crossed a state line with illicit intent to abuse her,
    and abused her, there is no question here about his having
    committed the offense during his abuse in Montana or North
    Dakota. But what is important to our analysis is that the con-
    tinuing offense did not terminate there. See 
    Lopez, 484 F.3d at 1192
    . Lukashov’s serial sexual abuse of T.F. continued
    UNITED STATES v. LUKASHOV               11431
    across the country to New York and back through Nevada to
    Oregon. There can be no doubt that T.F., an eight-year-old
    girl far from home in the custody of a man she called her
    “dad,” was in fear of continued abuse and under constant
    threat that the abuse would resume until reaching her home.
    Even if Lukashov did not physically abuse T.F. after crossing
    into Oregon, we conclude that at a minimum the significant
    element of the crime of illicit intent while crossing a state line
    continued in Oregon en route to her home. No evidence was
    presented on Lukashov’s intent to support a finding to the
    contrary. The evil intent and consequences of the crime neces-
    sarily continued into Oregon. We hold that this continuing
    offense of sexual abuse of a minor continued until T.F. was
    safely home. Cf. 
    Rodriguez-Moreno, 526 U.S. at 281
    (“A kid-
    naping, once begun, does not end until the victim is free.”);
    
    Lopez, 484 F.3d at 1188
    (holding that “a ‘brings to’ offense
    under [8 U.S.C.] § 1324(a)(2) terminates when the initial
    transporter drops the aliens off at a location in the United
    States”).
    The district court correctly perceived that once the jury
    found beyond a reasonable doubt that Lukashov had sexually
    abused T.F. on the trip to New York and back to Portland, the
    government had “necessarily” proved venue by a preponder-
    ance of the evidence because the offense continued into and
    was completed in Oregon as a matter of law. No rational jury
    could have failed to so conclude.
    [16] We hold that venue was proper under the first para-
    graph of § 3237(a) and need not address the district court’s
    alternative holding based on the second paragraph of
    § 3237(a).
    AFFIRMED.
