    Luis Alfredo Moreira-Bravo pleaded guilty to transporting a minor with intent
    to engage in criminal sexual activity in violation of 
    18 U.S.C. § 2423
    (a) after the
    district court 1 denied his motion in limine. He appeals that denial, and we affirm.
    1
    The Honorable Stephanie M. Rose, Chief Judge, United States District Court
    for the Southern District of Iowa.
    I.
    In May 2020, twenty-six-year-old Moreira-Bravo drove from Minnesota to
    Iowa to meet with fourteen-year-old R.M. Moreira-Bravo and R.M. had sex in
    Moreira-Bravo’s car, drove to Minnesota, and had sex again. R.M. never told
    Moreira-Bravo that she was under eighteen. She instead told him that she was at
    least nineteen years old. On May 7, officers observed Moreira-Bravo and R.M.
    together and arrested Moreira-Bravo. When questioned, he claimed that he believed
    R.M. was nineteen years old.
    Moreira-Bravo was indicted for transporting a minor with intent to engage in
    criminal sexual activity under 
    18 U.S.C. § 2423
    (a). He filed a motion in limine
    asking the district court to instruct the jury that § 2423(a) required the Government
    to prove that (1) he knew R.M. was underage and (2) he intended the unlawful nature
    of the sexual activity. The district court denied the motion. Moreira-Bravo
    conditionally pleaded guilty while reserving his right to appeal the denial of his
    motion in limine. See Fed. R. Crim. P. 11(a)(2). In his plea agreement, Moreira-
    Bravo stipulated that he transported R.M. from Iowa to Minnesota intending to
    engage in sexual activity with her, that they engaged in sexual activity upon arrival
    in Minnesota, and that he was more than 120 months older than fourteen-year-old
    R.M. at the time. To satisfy the § 2423(a) element of “intent that the [transported]
    individual engage in . . . sexual activity for which any person can be charged with a
    criminal offense,” the agreement named the Minnesota state offense of criminal
    sexual conduct in the third degree, which at the time criminalized intercourse with a
    victim between thirteen and sixteen years old by a person more than twenty-four
    months older. See 
    Minn. Stat. § 609.344
    , subd. 1(b) (2019), amended by 
    Minn. Stat. § 609.344
    , subd. 1a(b) (2021). Mistake of age was no defense to a violation of
    section 609.344 if the defendant was more than 120 months older than the victim.

    II.
    “We review questions of statutory interpretation de novo.” United States v.
    Schostag, 
    895 F.3d 1025
    , 1027 (8th Cir. 2018). Section 2423(a) states:
    A person who knowingly transports an individual who has not attained
    the age of 18 years in interstate or foreign commerce, or in any
    commonwealth, territory or possession of the United States, with intent
    that the individual engage in prostitution, or in any sexual activity for
    which any person can be charged with a criminal offense, shall be fined
    under this title and imprisoned not less than 10 years or for life.
    This case concerns the two mens rea requirements: “knowingly” and “with intent
    that.” Moreira-Bravo argues that § 2423(a) requires proof that he both (1) knew
    R.M. had not attained the age of eighteen and (2) intended the unlawfulness of the
    sexual activity. The district court construed § 2423(a) to require neither. We agree
    with the district court.
    A.
    Moreira-Bravo first argues that § 2423(a) requires knowledge of the victim’s
    underage status. We follow the nine other circuits to address this question and hold
    that it does not. See United States v. Tavares, 
    705 F.3d 4
    , 19-20 (1st Cir. 2013);
    United States v. Griffith, 
    284 F.3d 338
    , 350-51 (2d Cir. 2002); United States v.
    Tyson,

    , 144 (3d Cir. 2020); United States v. Washington,

    2022 WL 17408288
     (Dec. 5, 2022); cf. United States v. Daniels, 
    685 F.3d 1237
     (11th Cir. 2012) (per curiam) (adopting the reasoning of other circuits
    regarding § 2423(a) to find that the mens rea did not apply to the age requirement in
    
    18 U.S.C. § 2422
    (b)).
    -3-
    Moreira-Bravo invokes two presumptions of statutory construction found in
    Flores-Figueroa v. United States, 
    556 U.S. 646
     (2009), and Rehaif v. United States,
    588 U.S. ---, 
    139 S. Ct. 2191
     (2019). Flores-Figueroa established the text-based
    presumption that the adverbial mens rea “knowingly” applies to all subsequently
    listed elements (the “all-subsequent-elements presumption”). See 
    556 U.S. at 650
    .
    Rehaif appealed to the longstanding presumption that a mens rea applies to every
    element that separates criminal from innocent conduct (the “otherwise-innocent-
    conduct presumption”). See 
    139 S. Ct. at 2196-97
    . Under these presumptions,
    Moreira-Bravo argues, the mens rea “knowingly” applies to the age requirement
    because it is a subsequently listed element that separates innocent from criminal
    conduct. We disagree.
    1.
    “[W]e begin with the statute’s plain language,” United States v. Raiburn, 
    20 F.4th 416
    , 422 (8th Cir. 2021), giving “words . . . the meaning that proper grammar
    and usage would assign them,” Nielsen v. Preap, 536 U.S. ---, 
    139 S. Ct. 954
    , 965
    (2019) (internal quotation marks and citations omitted). Prior to Flores-Figueroa,
    we noted that “qualifying words and phrases . . . apply only to the words or phrases
    immediately preceding or following them.” See United States v. Mendoza-Gonzales,
    
    520 F.3d 912
    , 915 (8th Cir. 2008) (citing 2A Norman J. Singer & J.D. Shambie
    Singer, Sutherland Statutory Construction § 47:33 (7th ed. 2007)), cert. granted,
    judgment vacated, 
    556 U.S. 1232
     (2009), and abrogated by Flores-Figueroa, 
    556 U.S. 646
    . Under this approach, “knowingly” would modify only the verb
    “transports,” and not the subsequent elements. But in ordinary usage, “a mental
    state adverb can modify some or all of the remaining words in a sentence.” United
    States v. Figueroa, 
    165 F.3d 111
    , 115 (2d Cir. 1998). For example, “if a bank official
    says, ‘Smith knowingly transferred funds to his brother’s account,’ we would
    normally understand the bank official’s statement as telling us that Smith knew the
    account was his brother’s.” Flores-Figueroa, 
    556 U.S. at 650
    . Or the adverb might
    attach to only part of the ensuing phrase, as in the sentence, “‘[t]he mugger
    knowingly assaulted two people in the park—an employee of company X and a
    -4-
    jogger from town Y.’ A person hearing this sentence would not likely assume that
    the mugger knew about the first victim’s employer or the second victim’s
    hometown.” 
    Id. at 659
     (Alito, J., concurring). And the sentence, “Ted knowingly
    stole expensive toys from a toy store that was on the verge of bankruptcy,” indicates
    that Ted knew he stole toys, knew they were expensive, and knew they came from
    the toy store. But whether Ted knew about the bankruptcy is ambiguous. Thus, in
    some statutory phrases that use the word “knowingly,” “neither grammar nor
    punctuation resolves the question of how much knowledge Congress intended to be
    sufficient for a conviction.” Figueroa, 
    165 F.3d 111
    , 115; see also Liparota v.
    United States, 
    471 U.S. 419
    , 425 (1985) (quoting W. LaFave & A. Scott, Criminal
    Law § 27 (1972)) (“[I]t is not at all clear how far down the sentence the word
    ‘knowingly’ is intended to travel.”).
    The all-subsequent-elements presumption helps resolve this ambiguity. In
    Flores-Figueroa, the Supreme Court interpreted 18 U.S.C. § 1028A(a)(1), which
    penalizes the offender who “knowingly . . . uses . . . a means of identification . . . of
    another person.” The statute’s similar syntax to § 2423(a) is apparent. Compare
    § 1028A(a)(1) (punishing an offender who “knowingly [(adverb)] . . . uses [(verb)]
    . . . a means of identification [(direct object)] . . . of another person” (modifier of
    direct object)), with § 2423(a) (punishing the offender who “knowingly [(adverb)]
    transports [(verb)] an individual [(direct object)] who has not attained the age of 18
    years” (modifier of direct object)). Faced with § 1028A(a)(1), the government
    claimed it did not need to prove that the defendant knew the identification he used
    belonged to “another person.” Flores-Figueroa, 
    556 U.S. at 648
    . The Court rejected
    this argument because “[a]s a matter of ordinary English grammar, it seems natural
    to read the statute’s word ‘knowingly’ as applying to all the subsequently listed
    elements of the crime.” 
    Id. at 650
    . Flores-Figueroa now stands for a presumption
    that the mens rea “knowingly” applies to all subsequently listed elements in a statute.
    See, e.g., United States v. Bruguier, 
    735 F.3d 754
    , 758 (8th Cir. 2013) (en banc).
    But the all-subsequent-elements presumption is not a bright-line rule; it “can
    be rebutted where the ‘context’ or ‘background circumstances’ of a statute lead to a
    -5-
    different reading.” See Bruguier, 735 F.3d at 761 (quoting Flores-Figueroa, 
    556 U.S. at 652
    ). Justice Alito, concurring in Flores-Figueroa, identified § 2423(a) as
    an “example” of a statute where “context may well rebut th[e all-subsequent-
    elements] presumption.” 
    556 U.S. at 660
    . We conclude that in § 2423(a), context
    does rebut the presumption.
    a.
    Congress codified § 2423(a) in the context of a longstanding, near-universal
    tradition of strict liability as to the victim’s age in child sex crimes. As the Court in
    Flores-Figueroa recognized, “sex crimes involving minors do not ordinarily require
    that a perpetrator know that his victim is a minor.” 
    556 U.S. at 653
    .
    At common law, the crime of child abduction was a strict-liability offense as
    to the victim’s age. See Oliver Wendell Holmes, Jr., The Common Law 58-59
    (1881). The classic statement of this rule came in Regina v. Prince: “The legislature
    has enacted that if anyone does this wrong act he does it at the risk of the girl turning
    out to be under sixteen. This opinion gives full scope to the doctrine of mens rea.”
    (1875) 13 Cox C.C. 138 (Eng.).
    Early American courts applied Prince to hold statutory rape a strict-liability
    crime as to the child’s age. See, e.g., Matthew T. Fricker & Kelly Gilchrist, United
    States v. Nofziger and the Revision of 
    18 U.S.C. § 207
    : The Need for a New
    Approach to the Mens Rea Requirements of Federal Criminal Law, 
    65 Notre Dame L. Rev. 803
    , 815 & n.58 (1990) (collecting cases); cf. Francis Bowes Sayre, Public
    Welfare Offenses, 
    33 Colum. L. Rev. 55
    , 73 n.66 (1933) (collecting cases in which
    reasonable mistake as to the victim’s age was no defense to child sex crimes). The
    Supreme Court acknowledged this approach to mens rea for child sex crimes in
    Morissette v. United States, 
    342 U.S. 246
     (1952), noting that the common law
    contained exceptions to Blackstone’s requirement that criminals have a “vicious
    will,” 
    id. at 251
    , including “sex offenses, such as rape, in which the victim’s actual
    -6-
    age was determinative despite defendant’s reasonable belief that the girl had reached
    [the] age of consent,” 
    id.
     at 251 n.8.
    This passage from Morissette played a key role in Bruguier, where we found
    that a statute making it a crime “knowingly” to have sex with an incapacitated person
    required knowledge of the victim’s incapacitated status. Bruguier, 735 F.3d at 757,
    763; see 
    18 U.S.C. § 2242
    (2)(A). The dissent cited Morissette to argue that “the
    victim’s status rather than the defendant’s knowledge is determinative.” Bruguier,
    735 F.3d at 777 (Murphy, J., concurring in part and dissenting in part). But the
    concurrence identified the difference between age and other statuses under the
    common-law tradition: “Morissette actually explains that ‘sex offenses, such as
    rape, in which the victim’s actual age’—not status—‘was determinative’ are one of
    the ‘few exceptions’ to the mens rea requirement . . . .” Id. at 772 (Riley, C.J.,
    concurring) (quoting Morissette, 
    342 U.S. at
    251-52 & n.8). Though Bruguier may
    support applying a mens rea to some status elements in sex crimes, it does not disturb
    the common-law treatment of the victim’s age in child sex crimes.
    Statutory rape was still almost universally a strict-liability crime as to the
    victim’s age when § 2423(a)’s current language was adopted in 1998, see 
    Pub. L. No. 105-314, § 103
    , 
    112 Stat. 2974
    , 2976 (1998). In 2003, twenty-nine states and
    the District of Columbia treated statutory rape as a strict-liability crime as to the
    child’s age in all circumstances, and eighteen states did so in at least some
    circumstances. Catherine L. Carpenter, On Statutory Rape, Strict Liability, and the
    Public Welfare Offense Model, 
    53 Am. U. L. Rev. 313
    , 385-91 (2003) (surveying
    state criminal statutes). Only three states had abandoned strict-liability statutory
    rape. 
    Id.
    If any crime “involve[s] [a] special context[],” it is § 2423(a). See Flores-
    Figueroa, 
    556 U.S. at 652
    . Congress enacted the current version of § 2423(a)
    against the longstanding, near-universal tradition of making defendants bear the risk
    that sexual participants might be underage. When Congress employs “terms of art
    in which are accumulated the legal tradition and meaning of centuries of practice, it
    -7-
    presumably knows and adopts the cluster of ideas that were attached to each
    borrowed word . . . and the meaning its use will convey to the judicial mind.”
    Morissette, 
    342 U.S. at 263
    . Given the centuries of strict-liability age elements in
    child sex crimes, we are convinced that Congress meant § 2423(a) to have a strict-
    liability age element as well.
    b.
    Another aspect of § 2423(a)’s context provides both further support for our
    conclusion and a potential limiting principle. Section 2423(a) is not just a child sex
    crime, but one in which the defendant has an opportunity to observe the victim. In
    United States v. X-Citement Video, Inc., the Court held that a statute prohibiting
    “knowingly” transporting child pornography under 
    18 U.S.C. § 2252
     required proof
    that the actor knew the victims were underage. 
    513 U.S. 64
    , 65-66 (1994). The
    Court explained that it was comfortable departing from the common law’s usual
    treatment of child sex offenses because “[t]he opportunity for reasonable mistake as
    to age increases significantly once the victim is reduced to a visual depiction . . . .”
    
    Id.
     at 72 n.2. Conversely, in the production of child pornography, criminalized at
    
    18 U.S.C. § 2251
    , like in statutory rape, “the perpetrator confronts the underage
    victim personally and may reasonably be required to ascertain that victim’s age.”
    See 
    id.
     Thus, the Court implied that knowledge of the victim’s age was not required
    under § 2251, see id. at 76 n.5, and we subsequently adopted that interpretation, see
    United States v. Wilson, 
    565 F.3d 1059
    , 1067-69 (8th Cir. 2009) (“Producers of child
    pornography, unlike distributors and downstream consumers, are more akin to
    statutory rapists who are not entitled to any mens rea safeguards.”).
    In another child-sex-crime statute, Congress provided a mens rea that varies
    based on whether the defendant could observe the victim. See 
    18 U.S.C. § 1591
    (a)-
    (c); United States v. Koech, 
    992 F.3d 686
    , 688 (8th Cir. 2021). Section 1591(a)
    criminalizes sex trafficking where the defendant “know[s]” or acts “in reckless
    disregard of the fact . . . that the [victim] has not attained the age of 18 years and will
    be caused to engage in a commercial sex act.” But § 1591(c) provides that when
    -8-
    “the defendant had a reasonable opportunity to observe the [victim] . . . the
    Government need not prove that the defendant knew, or recklessly disregarded the
    fact, . . . that the [victim] had not attained the age of 18 years.” In § 1591, Congress
    relied on the defendant’s opportunity to observe his victim to justify strict liability
    as to the victim’s age.
    Like production of child pornography under § 2251 and certain forms of sex
    trafficking under § 1591(a) but unlike transportation of child pornography under
    § 2252, transportation of a minor under § 2423(a) gives the defendant a reasonable
    opportunity to observe his victim. Someone who “knowingly transports” an
    individual is typically in that person’s presence during at least part of the
    transportation, as Moreira-Bravo was here. See, e.g., Tavares, 705 F.3d at 11-12
    (indicating that the defendant charged with violating § 2423(a) was in the
    transported victim’s presence); Griffith, 
    284 F.3d at 342
     (same); Tyson, 947 F.3d at
    141 (same); Washington, 743 F.3d at 940 (same); Daniels, 
    653 F.3d at 405
     (same);
    Cox, 
    577 F.3d at 834
     (same); Taylor, 
    239 F.3d at 996
     (same). It makes sense, then,
    that Congress let § 2423(a) defendants bear the risk of their victim being underage.
    c.
    Finally, § 2423(a)’s statutory context suggests the same result.
    Section 2423(b)-(d) criminalizes acts predicated on “illicit sexual conduct,” which
    is defined in § 2423(f)(2) to include, among other things, “any commercial sex act
    . . . with a person under 18 years of age.” Section 2423(g) provides an affirmative
    defense for prosecutions based on that form of illicit sexual conduct if the defendant
    “establish[es] by clear and convincing evidence, that the defendant reasonably
    believed that the person with whom the defendant engaged in the commercial sex
    act had attained the age of 18 years.” “[W]hen Congress includes particular
    language in one section of a statute but omits it in another—let alone in the very next
    provision—this Court presumes that Congress intended a difference in meaning.”
    Loughrin v. United States, 
    573 U.S. 351
    , 358 (2014) (internal quotation marks and
    brackets omitted). Congress explicitly provided a mistake-of-age defense for
    -9-
    prosecutions arising under a different subsection of § 2423. Its choice not to do the
    same for § 2423(a) suggests congressional intent that mistake of age should not
    provide a defense to prosecutions for transporting a minor. This statutory context
    further supports what § 2423(a)’s text, read properly in light of its historical context,
    already demands: “knowingly” does not apply to the age requirement.
    2.
    Nor are we persuaded to depart from this reading by the otherwise-innocent-
    conduct presumption. See Rehaif, 
    139 S. Ct. at 2196-97
    . A mens rea requirement
    generally applies to each element that criminalizes otherwise innocent conduct. 
    Id.
    According to Blackstone, an act committed “without a vicious will is no crime at
    all.” 4 William Blackstone, Commentaries *21. The Supreme Court has applied
    Blackstone’s principle to construe an explicit mental-state requirement as attaching
    to other elements to avoid a construction that “would require the defendant to have
    knowledge only of traditionally lawful conduct.” See, e.g., Staples v. United States,
    
    511 U.S. 600
    , 605, 614-15, 617-18 (1994) (applying a “knowing” mens rea to an
    element because the defendant’s actions were “entirely innocent” without that
    element). In other words, the otherwise-innocent-conduct presumption disfavors
    interpretations of criminal statutes that merely require proof of a “will,” not a will
    that is “vicious.” See 
    id. at 617
    . Three cases are particularly relevant here.
    In X-Citement Video, the Court interpreted 
    18 U.S.C. § 2252
    , which bans
    “knowingly transport[ing]” or “ship[ping]” and “knowingly receiv[ing] or
    distribut[ing]” visual depictions “if . . . the producing of such visual depiction
    involves the use of a minor engaging in sexually explicit conduct.” See 
    513 U.S. at 68
    ; § 2252(a)(1)(A), (2)(1)(A). The Court held that the defendant could not be guilty
    of violating § 2252 unless he knew that the victims were underage because underage
    status was “the crucial element separating legal innocence from wrongful conduct,”
    id. at 72-73, 78.
    -10-
    In Rehaif, the Court addressed the interaction of two statutory provisions. 139
    S. Ct. at 2194. 
    18 U.S.C. § 922
    (g) bars certain persons, including those illegally
    present in the United States, from possessing firearms. 
    18 U.S.C. § 924
    (a)(2) (2019)
    (amended 2022), penalizes anyone who “knowingly violates” § 922(g). The Court
    held that an unlawful alien does not knowingly violate § 922(g) if he knows he
    possesses a gun but does not know he is in the United States illegally. 139 S. Ct. at
    2194. The defendant had to know his prohibited status because “the possession of a
    gun can be entirely innocent.” Id. at 2194, 2197. The defendant’s illegal presence
    was the element separating wrongful from innocent conduct, so the mens rea applied
    to it.
    Finally, Ruan v. United States interpreted 
    21 U.S.C. § 841
    (a), which prohibits
    “[e]xcept as authorized . . . knowingly or intentionally . . . dispens[ing] a controlled
    substance.” 597 U.S. ---, 
    142 S. Ct. 2370
    , 2374 (2022). The question was whether
    “knowingly” applied to the prefatory clause, “except as authorized.” 
    Id. at 2375
    .
    The Court relied on the otherwise-innocent-conduct presumption to hold that it did,
    because “a lack of authorization is often what separates wrongfulness from
    innocence.” 
    Id. at 2377
    .
    In each of these cases, the disputed element (the performer’s age in
    X-Citement Video, the prohibited status in Rehaif, and the lack of authorization in
    Ruan) separated criminal from innocent conduct, and the Court relied on this fact to
    hold that the mens rea requirement applied to that element.
    Section 2423(a)’s age requirement, in contrast, does not separate wrongful
    from innocent conduct. Section 2421(a) criminalizes the exact same conduct as
    § 2423(a)—transporting an individual with intent that the individual engage in
    prostitution or unlawful sexual activity—without the age requirement. A person
    who does not know the victim’s age and thus might not think himself criminally
    liable under § 2423(a) is not “innocent” because his conduct still violates § 2421(a).
    See Rehaif, 
    139 S. Ct. at 2197
    . Furthermore, the age requirement would not separate
    wrongful from innocent conduct even if § 2423(a) existed in a vacuum. Stripped of
    -11-
    its age requirement, § 2423(a) would criminalize transporting an individual across
    state lines “with the intent that the individual engage in prostitution, or in any sexual
    activity for which any person can be charged with a criminal offense.” Under neither
    of these circumstances is the defendant innocent. Even under the sexual-activity
    prong of § 2423(a) (as opposed to the prostitution prong), the defendant still must
    intend that the victim engage in sexual activity that satisfies the elements of an
    underlying criminal offense, totally apart from the age of his transported victim. In
    other words, the victim’s age does not separate criminal from innocent conduct
    because the defendant must always intend conduct constituting a separate crime. In
    this case, for example, Moreira-Bravo stipulated to intending sexual activity for
    which he would be liable under Minnesota’s statutory rape law, see 
    Minn. Stat. § 609.344
    , subd. 1a(b), totally apart from his guilt or innocence under § 2423(a) and
    its age requirement.
    This case involves the added complication that the underlying criminal
    offense also happens to be a strict-liability crime as to the victim’s age. See 
    Minn. Stat. § 609.344
    , subd. 1a(b). But this coincidence is no reason to change our
    construction of § 2423(a). The victim’s age does double duty in this case, allowing
    a plausible argument that the victim’s age is the only thing separating criminal from
    innocent conduct. But that will not always be the case. There are many other types
    of “sexual activity for which any person can be charged with a criminal offense,”
    § 2423(a), that do not involve a strict-liability age element and consequently require
    a “vicious will,” Morissette, 
    342 U.S. at 251
    . If, for example, a defendant transports
    an underage victim across state lines with the intent of forcibly raping the victim,
    the defendant’s conduct is, to say the least, not “innocent” regardless of the victim’s
    age. See Rehaif, 
    139 S. Ct. at 2197
    . And other sexual crimes that do not rely on the
    participants’ ages are legion. 2 We must interpret the age requirement in § 2423(a)
    2
    A person can also be charged with a crime for, inter alia, incest, see, e.g.,
    Ind. Code. § 35-46-1-3 (2022), bestiality, see, e.g., 
    Cal. Penal Code § 286.5
     (2022),
    adultery, see, e.g., 
    Fla. Stat. § 798.01
     (2022), cohabitation, see, e.g., 
    Mich. Comp. Laws § 750.335
     (2022), and fornication, see, e.g., 
    Miss. Code Ann. § 97-29-1
    (2022), and could have been charged for sodomy when Congress enacted the current
    -12-
    without peeking at the elements of the underlying sexual offense that happened to
    form the predicate for Moreira-Bravo’s conviction. Lacking such a peek, we cannot
    say that the age requirement itself separates criminal from innocent conduct—the
    “intent” requirement and the attendant underlying crime do that.
    At oral argument, Moreira-Bravo distinguished our unanimous sister circuits
    using a flawed application of the otherwise-innocent-conduct presumption. Those
    cases, he correctly argued, arose under the prostitution prong of § 2423(a) instead of
    the sexual-activity prong. But see Morgan, 45 F.4th at 196, 208 (deciding in August
    2022 that knowledge of the underage status of the victim was not required in a case
    arising under the sexual-activity prong of § 2423(a)). Because prostitution is always
    non-innocent, the victim’s age did not separate criminal from innocent conduct in
    those cases. In contrast, Moreira-Bravo argues, his conduct would have been
    innocent had R.M. been over eighteen. Thus, her underage status does separate
    criminal from innocent conduct here, so we should require knowledge of it.
    But Moreira-Bravo incorrectly assumes that all conduct falling under the
    sexual-activity prong relies on the victim’s age for its criminality. As discussed
    above, that is far from true. Many sexual crimes have nothing to do with the
    participants’ ages. Moreira-Bravo’s logic encourages the oddly divergent result of
    requiring knowledge of the transported victim’s age when a minor is transported to
    engage in statutory rape but not when the minor is transported to engage in any other
    criminal sexual activity. Like the D.C. Circuit, we decline to interpret a single piece
    of statutory language differently depending on the underlying facts of the case. See
    id. at 208 (concluding that it would be implausible to require knowledge of underage
    status when the underlying offense is criminal sexual activity but not when the
    underlying offense is prostitution).
    version of § 2423(a) in 1998, see, e.g., 
    Tex. Penal Code Ann. § 21.06
     (1998). None
    of these crimes rely on the participants’ age for their criminality.
    -13-
    In sum, the age of the victim does not separate criminal from innocent conduct
    in § 2423(a) because the other conduct in the statute—prostitution and unlawful
    sexual activity—is not innocent.
    *      *      *
    Neither the all-subsequent-elements presumption nor the otherwise-innocent-
    conduct presumption applies to § 2423(a), and the statute’s context shows that
    Congress did not intend to require knowledge of the victim’s age. The district court
    correctly held that the Government did not have to prove that Moreira-Bravo knew
    R.M. had “not attained the age of 18 years.” See § 2423(a).
    B.
    Moreira-Bravo’s next argument focuses on the latter portion of § 2423(a)—
    the requirement that the defendant act “with intent that the [transported] individual
    engage . . . in any sexual activity for which any person can be charged with a
    criminal offense.” He argues that this language requires the Government to prove
    that he intended both that R.M. engage in sexual activity and that she engage in
    conduct that is unlawful as such. Moreira-Bravo again invokes the all-subsequent-
    elements presumption and the otherwise-innocent-conduct presumption, claiming
    that the phrase “with intent that” applies to the criminality element.
    Unlike the word “knowingly,” the phrase “with intent that” is not most
    naturally read as “applying to all the subsequently listed elements of the crime,” at
    least as it appears in § 2423(a). See Flores-Figueroa, 
    556 U.S. at 650
    . By arguing
    that the defendant must not only intend the actions constituting the crime (i.e., sexual
    activity) but also some further result (i.e., that the sexual activity be unlawful),
    Moreira-Bravo essentially claims that § 2423(a) is a specific-intent crime. Cf.
    United States v. Robertson, 
    606 F.3d 943
    , 954 (8th Cir. 2010) (explaining that
    “specific intent is the intent to accomplish the precise criminal act that one is later
    charged with” (internal quotation marks and brackets omitted)). Specific-intent
    -14-
    crimes are crimes of “purpose,” where the defendant “consciously desires th[e]
    result,” in contrast to crimes of “knowledge,” where the defendant does not
    necessarily desire the result even “if he is aware that that result is practically certain
    to follow.” 
    Id.
     Here, it would be strange for Congress to target actors who (1) intend
    that their victims engage in sexual activity and (2) intend that it results in
    lawbreaking yet fail to target actors who (1) intend that their victims engage in sexual
    activity but (2) merely know—or are even “practically certain”—that it involves
    lawbreaking. See 
    id.
     Such a reading would create a marked imbalance between the
    proof required for convictions based on the prostitution prong (where intending the
    activity itself suffices) and the proof required for convictions based on other
    unlawful sexual activity. The two means of violating the statute are parallel; we do
    not think Congress singled out the second means—unlawful sexual activity—by
    restricting its scope to cover only those who fetishize lawbreaking. Cf. United States
    v. Cacioppo, 
    460 F.3d 1012
    , 1019 (8th Cir. 2006) (“Nothing in the statute’s
    language, structure or history indicates to us that Congress meant to apply different
    mens rea standards to two different means of violating [18 U.S.C.] § 1027.”).
    Furthermore, Moreira-Bravo’s interpretation “is in direct conflict with the
    ‘common maxim, familiar to all minds, that ignorance of the law will not excuse any
    person, either civilly or criminally.’” United States v. Hutzell, 
    217 F.3d 966
    , 968
    (8th Cir. 2000) (quoting Barlow v. United States, 
    32 U.S. (7 Pet.) 404
    , 411 (1833))
    (reaffirming that a statute imposing penalties on those who “knowingly violate” 
    18 U.S.C. § 922
    (g) “does not require knowledge of the law nor an intent to violate it”).
    Although there is a “very limited exception to the general rule that ignorance of the
    law is no excuse,” that exception applies only if the statute prohibits “activities that
    are not per se blameworthy” and the defendant’s “lack of awareness of the
    prohibition was [not] objectively unreasonable.” 
    Id.
     Neither requirement is met
    here.
    First, transportation of an underage person with intent that the victim engage
    in sexual activity is “per se blameworthy”—so much so that such conduct is
    traditionally punished as a strict-liability offense, as discussed above. See 
    id.
     In
    -15-
    other words, not requiring proof of intent to violate the law does not risk the
    criminalization of “innocent” conduct. See Rehaif, 
    139 S. Ct. at 2197
    .
    Second, a defendant who transports a young person with the intent that the
    victim engage in sexual activity cannot reasonably claim a lack of awareness of
    criminal laws restricting sexual activity, such as the Minnesota offense underlying
    Moreira-Bravo’s conviction. See, e.g., Owens v. State, 
    724 A.2d 43
    , 51 (Md. 1999)
    (explaining that sex “involves conscious activity which gives rise to circumstances
    that place a reasonable person on notice of potential illegality”); Commonwealth v.
    Robinson, 
    438 A.2d 964
    , 966 (Pa. 1981) (“[O]ne eighteen years of age or older who
    engages in sexual intercourse with a child below fourteen years of age does so at his
    own peril.”); State v. Haywood, No. 78276, 
    2001 WL 664121
     at *5 (Ohio Ct. App.
    2001) (unpublished) (“American culture . . . is . . . rife with warnings against sexual
    conduct with children. . . . Any person contemplating sexual conduct with a child in
    this age range should be cautious—the existence of ‘statutory rape’ laws is hardly a
    secret.”); State v. Carlson, 
    767 A.2d 421
    , 426-27 (N.H. 2001) (“[T]he defendant
    placed himself in risky circumstances, relying only on the victim’s ‘mature’
    behavior to substantiate her representation of her age.”). Thus, sexual activity,
    especially when it involves a young person, is comparable to other conduct that gives
    defendants notice of strict regulation. See, e.g., Hutzell, 
    217 F.3d at 969
     (declining
    to require knowledge of unlawfulness where “[n]o one can reasonably claim . . . to
    be unaware of the current level of concern about domestic violence”); United States
    v. Freed, 
    401 U.S. 601
    , 609 (1971) (noting that “one would hardly be surprised to
    learn that possession of hand grenades is not an innocent act” where the law at issue
    was “a regulatory measure in the interest of the public safety”); United States v. Int’l
    Mins. & Chem. Corp., 
    402 U.S. 558
    , 559, 561-62 (1971) (holding that a statute did
    not require knowledge of the regulated status of sulfuric acid); United States v.
    Balint, 
    258 U.S. 250
    , 254 (1922) (holding that the “person dealing in drugs” must
    “ascertain at his peril whether that which he sells comes within the inhibition of [a]
    statute” and is permissibly subject to criminal penalties despite his “ignorance” of a
    drug’s illegality).
    -16-
    Section 2423(a) “does not signal an exception to the rule that ignorance of the
    law is no excuse.” See Int’l Mins., 
    402 U.S. at 562
    . Therefore, a § 2423(a)
    conviction predicated on intent to engage in unlawful sexual activity does not require
    proof of the defendant’s intent or knowledge that such activity is unlawful. See
    United States v. Goodwin, 
    719 F.3d 857
    , 863 (8th Cir. 2013) (holding that evidence
    sufficiently supported a § 2423(a) conviction where the defendant intended that a
    seventeen-year-old engage in sexual activity in Texas—where the age of consent
    was seventeen—but where the victim was a minor under North Dakota law and a
    North Dakota jurisdictional statute enabled prosecution). The district court correctly
    held that the Government did not need to prove that Moreira-Bravo specifically
    intended R.M. to engage in sexual activity that was unlawful as such. It was required
    to prove only (1) that he intended R.M. to engage in sexual activity and (2) that the
    sexual activity was unlawful.
    III.
    For the foregoing reasons, we affirm the judgment of the district court.
    GRASZ, Circuit Judge, dissenting.
    It is fundamental that a statute is to be interpreted according to its plain
    language and, if necessary, by using rules of statutory construction. We do not
    typically depart from this course to find statutory meaning from tradition or by
    looking to common law to support counter-textual “special context.” Yet the court
    today holds that when trying to convict a person of violating 
    18 U.S.C. § 2423
    (a) the
    government need not prove the defendant knew the person transported was under
    eighteen years old. Because I believe both the plain language of the statute and well-
    established rules of statutory construction demand otherwise, I respectfully dissent.
    -17-
    Subsection (a) relevantly states:
    A person who knowingly transports an individual who has not attained
    the age of 18 years in interstate . . . commerce, . . . with intent that the
    individual engage in prostitution, or in any sexual activity for which
    any person can be charged with a criminal offense, shall be fined under
    this title and imprisoned not less than 10 years or for life.
    
    18 U.S.C. § 2423
    (a) (emphasis added).
    This language is not ambiguous. “In ordinary English, where a transitive verb
    has an object, listeners in most contexts assume that an adverb (such as knowingly)
    that modifies the transitive verb tells the listener how the subject performed the entire
    action, including the object as set forth in the sentence.” Flores-Figueroa v. United
    States, 
    556 U.S. 646
    , 650 (2009). Or as Justice Scalia explained, “‘[k]nowingly’ is
    not limited to the statute’s verb[],” and “once it is understood to modify the object
    of [the] verb[], there is no reason to believe it does not extend to the phrase which
    limits that object[.]” 
    Id. at 657
     (Scalia, J., concurring in part and concurring in the
    judgment). Applying the grammatical rule here, “knowingly” modifies both
    “transports” and “an individual who has not attained the age of 18 years[.]” 
    18 U.S.C. § 2423
    (a). Thus, in order to convict Moreira-Bravo, the government should
    have to prove he knew the person being transported was under eighteen. “Ordinary
    English usage supports this reading[.]” Flores-Figueroa, 
    556 U.S. at 657
     (Scalia,
    J., concurring in part and concurring in the judgment). When the plain text is clear,
    our inquiry generally ends. See id.; United States v. Boyster, 
    436 F.3d 986
    , 990 (8th
    Cir. 2006).
    The court, however, decides “context” requires an alternative interpretation of
    § 2423. Ante, at 6. I respectfully disagree. The Supreme Court in Flores-Figueroa
    did recognize “the inquiry into a sentence’s meaning is a contextual one” and that a
    “special context” may in some circumstances overcome the plain meaning of the
    statute. 
    556 U.S. at 652
    . But the Court concluded “no special context” was present
    and, to the contrary, explained “[t]he manner in which the courts ordinarily interpret
    -18-
    criminal statutes is fully consistent with this ordinary English usage.” 
    Id.
     3 “That is
    to say courts ordinarily read a phrase in a criminal statute that introduces the
    elements of a crime with the word ‘knowingly’ as applying that word to each
    element.” 
    Id.
     This should be true of the age element in § 2423(a).
    In this vein, the Supreme Court has “read into criminal statutes . . . that contain
    no mens rea provision whatsoever” the mens rea deemed necessary to divide
    wrongful conduct from what is otherwise innocent conduct. Ruan v. United States,
    
    142 S. Ct. 2370
    , 2377 (2022). This “is consistent with a basic principle that underlies
    the criminal law, namely, the importance of showing what Blackstone called ‘a
    vicious will.’” Rehaif v. United States, 
    139 S. Ct. 2191
    , 2196 (quoting 4 W.
    Blackstone, Commentaries on the Laws of England 21 (1769)). “And when a statute
    is not silent as to mens rea but instead ‘includes a general scienter provision,’ ‘the
    presumption applies with equal or greater force’ to the scope of that provision.”
    Ruan, 142 S. Ct. at 2377 (quoting Rehaif, 
    139 S. Ct. at 2197
    ).
    The Supreme Court has applied the presumption of scienter even in situations
    when applying “knowingly” to an element was not “the most grammatical reading
    3
    The court accurately notes that in Flores-Figueroa, Justice Alito pointed to
    § 2423(a) as an example where “context may well rebut [the] presumption,” 
    556 U.S. at 660
     (Alito, J., concurring in part and concurring in the judgment) (emphasis
    added), “that the specified mens rea applies to all the elements of an offense[.]” 
    Id.
    Justice Alito noted, “[t]he Courts of Appeals have uniformly held that a defendant
    need not know the victim’s age to be guilty under this statute.” 
    Id.
     But this passing
    observational dicta from a concurrence, to which no other Justice joined, certainly
    does not bind us. This is particularly true because since Flores-Figueroa the
    Supreme Court has, over Justice Alito’s objection, twice applied the presumption of
    scienter to criminal statutes even when the text is not clear Congress intended such
    a result. See Ruan v. United States, 
    142 S. Ct. 2370
    , 2382‒83 (2022) (Alito, J.,
    concurring in the judgment) (expressing disagreement with the Court’s application
    of the mens rea canon when interpreting 
    21 U.S.C. § 841
    (a)); Rehaif v. United States,
    
    139 S. Ct. 2191
    , 2201, 2213 (2019) (Alito, J., dissenting) (“The majority’s
    interpretation of [18 U.S.C.] § 922(g) is not required by the statutory text, and there
    is no reason to suppose that it represents what Congress intended.”).
    -19-
    of the statute[.]” United States v. X-Citement Video, Inc., 
    513 U.S. 64
    , 70 (1994).
    The Court has recently held the presumption applied so as to interpret the mens rea
    listed in one statute to apply to a cross-referenced statute that did not have a mens
    rea in its text. See Rehaif, 
    139 S. Ct. at
    2195–96. And just this year, the Supreme
    Court applied the presumption to an element that preceded the mens rea provided in
    the statute. See Ruan, 142 S. Ct. at 2381‒82 (rejecting a grammar-based argument
    that since the clause in question preceded the mens rea, the mens rea could not
    modify the clause). These recent applications of the presumption of scienter to such
    less-than-obvious situations should make clear the propriety of its application here
    in support of the plain meaning of the text.
    And in my view, § 2423(a) is not the kind of statute the Supreme Court has
    “held fall[s] outside the scope of ordinary scienter requirements.” Id. at 2378. While
    it is true the presumption need not be applied “in cases involving statutory provisions
    that form part of a ‘regulatory’ or ‘public welfare’ program and carry only minor
    penalties,” Rehaif, 
    139 S. Ct. at 2197
    , this statute does not fit that bill if for no other
    reason than the “harsh” penalties associated with it, 
    id.
     (quoting X-Citement Video,
    
    513 U.S. at 72
    ). Even if § 2423(a) could be characterized as a “public welfare
    offense,” the harsh penalty of imprisonment for “not less than 10 years or for life[,]”
    
    18 U.S.C. § 2423
    (a) (emphasis added), disqualifies this crime from the “exception
    to the presumption in favor of scienter[.]” Rehaif, 
    139 S. Ct. at 2197
    ; accord United
    States v. Bruguier, 
    735 F.3d 754
    , 761 (8th Cir. 2013) (en banc).
    Another canon of construction supports interpreting § 2423 to mean the
    government must prove knowledge of the individual’s age. “It is a ‘familiar
    principle that ambiguity concerning the ambit of criminal statutes should be resolved
    in favor of lenity.’” Bruguier, 735 F.3d at 761 (quoting Skilling v. United States,
    
    561 U.S. 358
    , 410 (2010)). This means that even if § 2423(a) was ambiguous as to
    whether “knowingly” applies to the age of the individual being transported, we
    should resolve the question in Moreira-Bravo’s favor. And such an interpretation is
    also consistent with another fundamental principle of law—notice. See FCC v. Fox
    Television Stations, Inc., 
    567 U.S. 239
    , 253 (2012).
    -20-
    The court is not swayed by these interpretative canons and instead focuses on
    other contextual clues which it believes reveal Congress did not intend “knowingly”
    to apply to the age requirement. First, the court focuses on its belief that “Congress
    codified § 2423(a) in the context of longstanding, near-universal tradition of strict
    liability as to the victim’s age in child sex crimes.” Ante, at 6. Given this backdrop,
    the court is “convinced that Congress meant § 2423(a) to have a strict-liability age
    element as well.” Id. at 8.
    I find this unpersuasive for several reasons. Most fundamentally, I do not
    believe this is a reason to ignore the plain text of the statute. Context may be reason
    to decline to apply the presumption of scienter when that presumption contradicts
    the plain meaning of the statutory text, but it should not be license to disregard the
    statute’s plain meaning. See Flores-Figueroa, 
    556 U.S. at 657
     (Scalia, J., concurring
    in part and concurring in the judgment) (refusing to join the Court’s reliance on other
    considerations when the plain meaning of the statute answered the question).
    Even putting this objection aside, I find the historical context less clear than
    the court does as it relates to § 2423(a)’s age requirement. While a majority of states
    have apparently treated statutory rape as a strict liability crime, many states have
    either treated it as a “true crime”—requiring the government prove the defendant
    had the mens rea—or at least allowed a mistake-of-age defense when the victim is
    close to the age of consent. See Catherine L. Carpenter, On Statutory Rape, Strict
    Liability, and the Public Welfare Offense Model, 53 Am. Univ. L. Rev. 313, 317–
    18, 385–91 (2003). “Indeed, in an attempt to distinguish the egregious felonious
    sexual activity from the non-egregious, many statutory schemes comprise complex,
    multi-layered age differential scenarios of victim and perpetrator.” Id. at 340.
    “Many states also recognize that sexual activity between high school age peers may
    be common and not necessarily meant for the chilling and punitive reach of the
    criminal law.” Id. at 340–41. My point in all this is simply that the picture is more
    complicated than the majority suggests. And thus, I believe there is insufficient
    evidence of the historical context to override the plain text of the statute.

    The court also claims a contextual clue from its belief that “[s]ection 2423(a)
    is not just a child sex crime, but one in which the defendant has an opportunity to
    observe the victim.” Ante, at 8. Relying on cases reviewing child pornography
    statutes, the court posits Moreira-Bravo’s opportunity to observe the victim justifies
    departure from the typical mens rea requirement because someone who personally
    observes the victim is less likely to mistakenly believe the victim is of age. Id. at 8‒
    9. This broad reading of caselaw is unavailing in part because § 2423(a) does not
    include such observation of the victim as an element of the crime. While most
    defendants charged with “knowingly transport[ing]” an individual in violation of
    § 2423(a) may very well have personally observed the victim, nothing in the statute
    requires this to be true.
    The court also reasons § 2423’s statutory context suggests Congress meant to
    let a defendant bear the risk of the victim being underage. Ante, at 9‒10. The court
    explains that because Congress provided a defendant charged with engaging in
    “illicit sexual conduct” under subsections (b)–(d) with an explicit mistake-of-age
    defense, but did not include such a defense to subsection (a), it suggests Congress
    found mistake of age irrelevant to the offense. Id. I disagree. The more likely
    explanation for the absence of a mistake-of-age defense in subsection (a) is that
    Congress did not believe the defense was necessary because, unlike the crimes
    specified in subsections (b)–(d), subsection (a) plainly requires the government
    prove a defendant’s knowledge as part of its case in chief. See 
    18 U.S.C. § 2423
    .
    In the end, none of the contextual clues utilized by the court convinces me that
    Congress meant something different than what the plain reading of the text dictates
    and interpretative canons reinforce—the government must prove Moreira-Bravo
    knew the individual transported was not yet eighteen years old. I therefore
    respectfully dissent.
