    OPINION OF THE COURT
    ______________
    RESTREPO, Circuit Judge.
    William Tyson was indicted for the transportation of a
    minor to engage in prostitution and the production of child
    pornography in violation of 
    18 U.S.C. § 2423
    (a) and 
    18 U.S.C. § 2251
    (a), respectively. During pre-trial proceedings, the
    District Court granted the Government’s motion in limine to
    exclude mistake-of-age evidence. Tyson and the Government
    2
    then submitted a conditional plea agreement preserving his
    right to appeal the District Court’s order. The District Court
    sentenced Tyson to concurrent terms of 180 months’
    imprisonment for each count.
    Tyson appeals the District Court’s grant of the
    Government’s motion in limine precluding him from
    introducing mistake-of-age evidence at trial. He argues that the
    District Court erred in precluding the evidence because
    knowledge of age is an element of § 2423(a) and § 2251(a). He
    also urges us to read an affirmative defense on lack of
    knowledge into each statute. We disagree. The statutes’ text,
    context, and history make it clear that knowledge of age is not
    an element and mistake of age is not a defense. Therefore, we
    will affirm the District Court’s order.
    I.
    In August 2017, Tyson contacted a seventeen-year-old
    female on Facebook to engage her in prostitution. After
    communicating for several days via Facebook and text
    messages, Tyson traveled from Pennsylvania to New York
    City. Tyson picked up the victim and her friend and brought
    them to Harrisburg, Pennsylvania. He then rented several
    rooms at a Motel 6 in New Cumberland, Pennsylvania between
    August 15 and August 20, 2017. Phone records reveal that
    Harrisburg-area individuals contacted the victim to engage in
    commercial sexual activity.
    On August 22, 2017, after a relative of Tyson brought
    the victim to a Quality Inn in New Cumberland, FBI agents and
    local law enforcement recovered her during a sting operation.
    Investigators interviewed her and reviewed her phone. They
    3
    found an August 20, 2017 video of the victim performing oral
    sex on an adult male in a Motel 6 room. The victim identified
    the man in the video as “Real,” whom the investigators
    identified as Tyson.
    On October 18, 2017, Tyson was indicted for
    knowingly transporting a minor to engage in prostitution in
    violation of § 2423(a) and producing child pornography in
    violation of § 2251(a). Before trial, the Government filed a
    motion in limine to prohibit Tyson “from eliciting evidence to
    establish ‘mistake of age’” and from asserting “mistake of age”
    as an affirmative defense. App. 21. The District Court granted
    the motion on July 11, 2018. The Court found that evidence of
    mistake of age is irrelevant to § 2423(a) and § 2251(a) because
    the statutes do not require proof of defendants’ knowledge that
    the victim was a minor. As a result, the Court excluded the
    evidence because “its probative value is substantially
    outweighed by a risk that the evidence will result in unfair
    prejudice, confuse the issues, or mislead the jury” under
    Federal Rule of Evidence 403. See App. 10.
    Tyson and the Government subsequently entered a plea
    agreement. According to its terms, Tyson and the Government
    agreed to recommend to the District Court that the sentences
    be served concurrently for a total of 180 months’
    imprisonment. The agreement also preserved Tyson’s right to
    appeal the District Court’s July 11, 2018 order granting the
    Government’s motion in limine. On December 19, 2018, the
    District Court sentenced Tyson to 180 months’ imprisonment
    for each count, to be served concurrently. Tyson filed a Notice
    of Appeal with this Court on December 24, 2018 challenging
    the District Court’s order.

    II.
    The District Court had jurisdiction pursuant to 
    18 U.S.C. § 3231
    . We have jurisdiction under 
    28 U.S.C. § 1291
    and 
    18 U.S.C. §3742
    (a).
    This Court reviews decisions on the admissibility of
    evidence for abuse of discretion. United States v. Higdon, 
    638 F.3d 233
    , 238 (3d Cir. 2011). District court conclusions on
    whether “the risk of unfair prejudice does not substantially
    outweigh the probative value of otherwise admissible
    evidence” are reviewed under the same standard. 
    Id.
     We
    exercise plenary review over legal questions and district court
    rulings based on interpretations of the Federal Rules of
    Evidence. See United States v. Schiff, 
    602 F.3d 152
    , 160–61
    (3d Cir. 2010); United States v. Serafini, 
    233 F.3d 758
    , 768
    n.14 (3d Cir. 2000). Statutory construction determinations are
    reviewed de novo. United States v. Cochran, 
    17 F.3d 56
    , 57
    (3d Cir. 1994) (en banc).
    III.
    Tyson posits that the District Court erred in prohibiting
    evidence related to mistake of age because § 2423(a) and §
    2251(a) require knowledge that the victim was a minor to find
    a defendant guilty. He characterizes knowledge of age as an
    element of each statute. Tyson points to title 18, section 5902
    of the Pennsylvania Statutes and Consolidated Statutes to
    suggest that Pennsylvania law provides a mistake-of-age
    defense to a prosecution based on § 2423(a). Tyson also turns
    to a Ninth Circuit decision interpreting § 2251(a) to require a
    mistake-of-age defense to correct the statute’s supposed
    constitutional deficiencies. We disagree and join the
    5
    overwhelming majority of our sister circuits holding that
    mistake of age is not a defense and knowledge of the victim’s
    age is not required for a conviction under either § 2423(a) or §
    2251(a). Thus, the District Court did not err in prohibiting
    Tyson from asserting a mistake-of-age defense under Federal
    Rule of Evidence 403.1
    A.
    The grand jury indicted Tyson for “knowingly
    transport[ing] [the victim], an[] individual who had not
    attained the age of 18 years, in interstate commerce, with the
    intent that [the victim] engage in prostitution” in violation of §
    2423(a). App. 15. The statute provides:
    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 the 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.
    § 2423(a) (emphasis added). The District Court agreed with the
    Government’s position that Tyson need not have known the
    1
    “The court may exclude relevant evidence if its
    probative value is substantially outweighed by a danger of one
    or more of the following: unfair prejudice, confusing the
    issues, misleading the jury, undue delay, wasting time, or
    needlessly presenting cumulative evidence.” Fed. R. Evid. 403.
    6
    victim’s age in order to have knowingly transported a minor.
    Tyson argues that the Government must prove the defendant’s
    knowledge of the victim’s age under § 2423(a). He points to
    the presumption that the mens rea requirement generally
    extends to each element of a criminal statute.
    In Flores-Figueroa v. United States, the Supreme Court
    explained that “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.” 
    556 U.S. 646
    , 652 (2009).2 Even though the mens rea typically applies
    to all the elements, the majority recognized the existence of
    special contexts where courts may deviate from that general
    presumption. See 
    id.
    Concurring, Justice Alito elaborated on examples of
    special contexts that rebut the general presumption. He
    specifically mentioned § 2423(a) as an example of a statute that
    calls for a contextual approach to statutory interpretation and
    added that circuit courts “uniformly [hold] that a defendant
    need not know the victim’s age to be guilty under [§2423(a)].”
    Id. at 660 (Alito, J., concurring). The Flores-Figueroa majority
    referenced Justice Alito’s concurrence with apparent approval.
    Id. at 652 (noting that sentences where “knowingly” only
    2
    At issue in Flores-Figueroa was whether the term
    “knowingly” applies to all the elements in 18 U.S.C. §
    1028A(a)(1). The statute imposes a two-year sentence on
    individuals who “knowingly transfer[], possess[], or use[],
    without lawful authority, a means of identification of another
    person” during the commission of statutorily-defined felonies.
    § 1028A(a)(1).
    7
    modifies a “transitive verb . . . typically involve special
    contexts . . . [a]s Justice ALITO notes, the inquiry into a
    sentence’s meaning is a contextual one”). Tyson does not
    provide a compelling reason for us to disregard Justice Alito’s
    concurrence and the majority’s recognition that the general
    presumption does not apply in all contexts.
    An overwhelming number of our sister circuits that
    have considered § 2423(a)—both prior to and after Flores-
    Figueroa—have concluded that “knowingly” does not extend
    to the victim’s age.3 Interpreting a predecessor of § 2423(a),
    this Court held that “[t]he statute does not state or require
    knowledge of the victim’s age.” United States v. Hamilton, 
    456 F.2d 171
    , 173 (3d Cir. 1972) (per curiam). While Tyson is
    correct that Hamilton is not controlling authority as to the
    current statutory provision, in light of Flores-Figueroa, we are
    unconvinced that we should alter our approach.
    Arguing that the background presumption articulated in
    Flores-Figueroa applies to § 2423(a), Tyson ignores
    Congress’s clear intent that knowledge of age not be required
    for a conviction pursuant to the statute. Our role in interpreting
    statutes is to “give effect to Congress’s intent.” Idahoan Fresh

    157 F.3d 197
    , 202 (3d Cir. 1998).
    “We . . . look to statutory context for evidence of congressional
    intent.” United States v. Merlino, 
    785 F.3d 79
    , 92 (3d Cir.
    2015). In considering statutory context, courts interpret statutes
    in accordance with their overall scheme. Gundy v. United
    States, 
    139 S. Ct. 2116
    , 2126 (2019).
    Congress did not intend to require knowledge of a
    victim’s age for a conviction under § 2423(a). Congress’s
    purpose in enacting and amending § 2423(a) was to provide
    minors special protection against sexual mistreatment. See
    Taylor, 
    239 F.3d at
    997 (citing H.R. Rep. No. 105–557 (1998)).
    In the face of longstanding consensus among circuit courts that
    knowledge of age is not an element of § 2423(a), Congress has
    not added language to the statute “requir[ing] the government
    to establish the defendant’s knowledge of the alleged victim’s
    age.” United States v. Jones, 
    471 F.3d 535
    , 539 (4th Cir. 2006)
    (noting that Congress amended 
    18 U.S.C. § 2423
     nine times
    between 1978 and 2006). By not extending the mens rea
    requirement to the victim’s age, Congress eliminated
    offenders’ opportunity to prey on children without
    consequence by claiming ignorance of the victim’s age. 
    Id. at 540
    . A contrary interpretation would frustrate congressional
    intent to provide minors with heightened protection against
    sexual exploitation.
    The statute is best understood as establishing age as an
    aggravating factor that subjects defendants to increased
    penalties for conduct that is already prohibited under 
    18 U.S.C. § 2421.4
     Aside from § 2423(a)’s focus on minors, § 2421 and
    4
    Section 2421 criminalizes “knowingly transport[ing]
    any individual in interstate or foreign commerce . . . with intent
    9
    § 2423(a) are nearly identical. Cox, 
    577 F.3d at 837
    . As a
    result, those who transport individuals of any age across state
    lines to engage in prostitution are “already on notice that [they
    are] committing a crime.” Griffith, 
    284 F.3d at 351
    . Section
    2423(a) places the risk on perpetrators that the person they
    transport is a minor. Taylor, 
    239 F.3d at 977
     (“As Congress
    intended, the age of the victim simply subjects the defendant
    to a more severe penalty in light of Congress’ concern about
    the sexual exploitation of minors.”). Requiring knowledge of
    age for a conviction under § 2423(a) would make it more
    difficult to prove sexual exploitation of a minor than an adult.
    See Washington, 743 F.3d at 942; Jones, 
    471 F.3d at 539
    ; see
    also United States v. Fontaine, 
    697 F.3d 221
    , 227–28 (3d Cir.
    2012) (emphasizing that courts avoid absurd conclusions when
    interpreting statutes). Because knowledge of a minor’s age is
    not an element of § 2423(a), the lack of knowledge cannot be
    a defense.
    Tyson alternatively suggests that mistake of age is an
    affirmative defense to § 2423(a). However, the statute’s
    language does not create an affirmative mistake-of-age
    defense. Instead, § 2423 limits a mistake-of-age defense to a
    prosecution for a commercial sex act as defined in 
    18 U.S.C. § 2423
    (f)(2). 
    Id.
     § 2423(g) (“In a prosecution under this section
    based on . . . subsection (f)(2), it is a defense . . . 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.”). Section 2423(a) does not contain
    comparable language. The fact that Congress included a
    mistake-of-age defense for one subsection but not another
    that such individual engage in prostitution, or in any [criminal]
    sexual activity.”
    10
    indicates that Congress intended to limit the defense to the
    particular circumstance in § 2423(f)(2).
    Tyson next argues that § 2423(a) produces a piggyback
    offense requiring the Government to prove that he violated
    some other state or federal law. He suggests that we consider
    Pennsylvania’s law criminalizing prostitution of a minor. See
    
    18 Pa. Stat. and Cons. Stat. Ann. § 5902
    (b.1)(3) (defining
    “knowingly promot[ing] prostitution of a minor”—including
    “encouraging, inducing or otherwise intentionally causing a
    minor to become or remain a prostitute”—as a third degree
    felony). Tyson invokes Pennsylvania law to claim that it
    provides a mistake-of-age defense and therefore, a mistake-of-
    age defense to a charge under § 2423(a).5
    We do not adopt Tyson’s approach for two reasons.
    First, as the District Court noted, § 2423(a) criminalizes two
    categories of offenses: (1) engaging in prostitution and (2)
    engaging in any other sexual activity prohibited by state or
    federal law. Tyson was indicted on a prostitution charge rather
    than under the catch-all category.6 Adopting Tyson’s approach
    5
    Tyson cites to statutory language providing that
    “[w]hen criminality depends on the child’s being below a
    critical age older than 14 years, it is a defense for the defendant
    to prove by a preponderance of the evidence that he or she
    reasonably believed the child to be above the critical age.” 
    18 Pa. Stat. and Cons. Stat. Ann. § 3102
    .
    6
    Tyson evokes the Seventh Circuit’s recognition that
    “Section 2423(a) creates a piggyback offense” requiring the
    Government to “show that the sexual activity after crossing the
    state line violated some other statute.” United States v. Ray,
    11
    would deprive the term “prostitution” of meaning since §
    2423(a) already prohibits sexual activity that constitutes a
    criminal offense. See Duncan v. Walker, 
    533 U.S. 167
    , 174
    (2001) (“[A] statute ought . . . to be so construed that . . . no
    clause, sentence, or word shall be superfluous, void, or
    insignificant.”).
    Second, even if section 5902(b.1)(3) were to constitute
    the specific offense in this case, it does not provide a mistake-
    of-age defense. Though Pennsylvania law does provide a
    mistake-of-age defense, it is limited to sexual offenses listed in
    Chapter 31 of Pennsylvania’s consolidated statutes. See § 3102
    (clarifying situations where the defense is available “in this
    chapter” for criminal conduct). Section 5902(b.1)(3), which is
    listed under Chapter 59, neither requires knowledge of age as
    an element of a prostitution offense nor provides a mistake-of-
    age defense.7
    We join our sister circuits and hold that mistake of age
    is not a defense to § 2423(a) and that the Government is not
    required to prove knowledge of the victim’s age. Thus, the
    District Court did not err in concluding that mistake-of-age
    
    831 F.3d 431
    , 434 (7th Cir. 2016). However, unlike Tyson, the
    defendant in Ray was indicted for a state offense under §
    2423(a)’s catch-all category. See id. (“The indictment charged
    Ray with aggravated criminal sexual abuse, in violation of 720
    ILCS 5/11-1.60 . . . .”).
    7
    Tyson acknowledged that Pennsylvania law does not
    recognize a mistake-of-age defense to the crime of prostitution.
    Oral Arg. at 10:48.
    12
    evidence is irrelevant to a prosecution pursuant to § 2423(a)
    and would likely mislead the jury.
    B.
    In addition to the § 2423(a) count, the grand jury
    indicted Tyson for knowingly using a minor to produce child
    pornography in violation of § 2251(a). The statute states:
    Any person who employs, uses, persuades,
    induces, entices, or coerces any minor to engage
    in . . . or who transports any minor in or affecting
    interstate or foreign commerce . . . with the intent
    that such minor engage in, any sexually explicit
    conduct for the purpose of producing any visual
    depiction of such conduct or for the purpose of
    transmitting a live visual depiction of such
    conduct, shall be punished as provided under
    subsection (e), if such person knows or has
    reason to know that such visual depiction will be
    transported or transmitted using any means or
    facility of interstate or foreign commerce or in or
    affecting interstate or foreign commerce or
    mailed . . . or if such visual depiction has actually
    been transported or transmitted using any means
    or facility of interstate or foreign commerce or in
    or affecting interstate or foreign commerce or
    mailed.
    § 2251(a). In granting the Government’s motion in limine, the
    District Court concluded that “any evidence of mistake of age
    . . . is irrelevant” and would likely “confuse or mislead the
    jury” because the Government does not need to prove
    13
    knowledge of age under § 2251(a). App. 12–14. Tyson raises
    two arguments as to § 2251(a). First, he points to a perceived
    circuit split and lack of controlling authority on whether the
    Government must prove knowledge of age. Second, even if
    knowledge of age is not an element, Tyson argues that the First
    Amendment requires an affirmative mistake-of-age defense.
    Tyson claims that neither the Supreme Court nor this
    Court have definitely ruled on whether the Government must
    prove knowledge of age. In United States v. X-Citement Video,
    the Supreme Court analyzed § 2251(a) to clarify the meaning
    of 
    18 U.S.C. § 2252
    . The majority stated that child
    pornography “producers may be convicted under § 2251(a)
    without proof they had knowledge of age.” 
    513 U.S. 64
    , 76 n.5
    (1994); see also Cochran, 
    17 F.3d at
    60–61 (concluding that §
    2252 requires knowledge of age after contrasting it with §
    2251(a)). While Tyson is correct that these cases consider §
    2251(a) in dicta, we nonetheless view them as persuasive
    authority. See In re McDonald, 
    205 F.3d 606
    , 612 (3d Cir.
    2000) (“[W]e should not idly ignore considered statements the
    Supreme Court makes in dicta. The Supreme Court uses dicta
    to help control and influence the many issues it cannot decide
    because of its limited docket.”).
    To limit the persuasiveness of the § 2251(a) discussion
    in these cases, Tyson points to a supposed circuit split on the
    issue.8 Our sister circuits, however, have unequivocally held
    8
    Tyson cites to decisions from the First and Ninth
    Circuits to support his argument that there exists a circuit split.
    See United States v. Encarnación-Ruiz, 
    787 F.3d 581
     (1st Cir.
    2015); United States v. U.S. District Court (Kantor), 
    858 F.2d 534
     (9th Cir. 1988). We are unpersuaded. While Encarnación-

    wake of the X-Citement Video decision, all of the federal courts
    of appeals that have considered the issue of scienter under §
    2251(a) have held that a defendant’s knowledge of the minor’s
    age is not an element of the offense.” Humphrey, 608 F.3d at
    960. We see no reason to depart from this consensus. Because
    of § 2251(a)’s unambiguous text and history, we join our sister
    circuits and hold that the Government is not required to prove
    knowledge of age.
    The statute’s text and history indicate that Congress did
    not intend to require the Government to prove knowledge of
    age or provide defendants with an affirmative mistake-of-age
    defense. Malloy, 568 F.3d at 171–72. Indeed, Congress
    specifically removed “knowingly” from § 2251(a)’s age
    element to facilitate enforcement of laws prohibiting the
    production of child pornography. See Cochran, 
    17 F.3d at
    60–
    61 (discussing Congress’s decision to delete “knowingly” from
    Ruiz is limited to an “aider and abettor’s knowledge that the
    victim was a minor,” 787 F.3d at 584, Tyson was solely
    charged as a principal. Furthermore, Kantor explicitly states
    that knowledge is not an element of the statute. 
    858 F.2d at 538
    (“The defendant’s awareness of the subject’s minority is not an
    element of the offense.”).

    a draft bill due to the Department of Justice’s concern that it
    would increase the difficulty of prosecuting child pornography
    producers).
    Criminal statutes aimed at protecting children from
    sexual offenses have long been considered exempt from the
    general scienter presumption. See Morissette v. United States,
    
    342 U.S. 246
    , 251 n.8 (1952) (“Exceptions [to the common law
    presumption] came to include sex offenses, such as rape, in
    which the victim’s actual age was determinative despite
    defendant’s reasonable belief that the girl had reached age of
    consent.”). Courts are particularly reluctant to impose a mens
    rea requirement to a minor’s age because the Government is
    “entitled to greater leeway in the regulation of pornographic
    depictions of children.” See New York v. Ferber, 
    458 U.S. 747
    ,
    756 (1982).
    Perhaps recognizing the lack of a textual or historical
    basis for a mistake-of-age defense, Tyson invites us to read an
    affirmative defense into the statute. He cites a Ninth Circuit
    decision holding that the First Amendment requires a mistake-
    of-age defense to a prosecution under § 2251(a). Appellant’s
    Br. 16–18 (citing Kantor, 
    858 F.2d at 540
    ). In that case, the
    Ninth Circuit reasoned that the “imposition of criminal
    sanctions on the basis of strict liability . . . would seriously chill
    protected speech.” Kantor, 
    858 F.2d at 540
    . Rather than
    invalidating the statute, the majority instead recognized an
    affirmative mistake-of-age defense. 
    Id. at 542
    . We decline
    Tyson’s invitation to join the Ninth Circuit in recognizing an
    affirmative defense under the First Amendment. See
    Humphrey, 
    608 F.3d at 960
     (noting that “the Ninth Circuit
    16
    stands alone in its determination that the First Amendment
    requires a reasonable mistake-of-age defense”).10
    We are unconvinced that excluding mistake-of-age
    evidence poses a substantial risk to protected expression.
    Perpetrators are well positioned to know the age of a victim
    because they “confront[] the underage victim personally.” X-
    Citement Video, 
    513 U.S. at
    72 n.2. As for legitimate
    producers, only a small subset of pornography—that which
    involves “youthful-looking” performers—can conceivably be
    subject to criminal prosecution under § 2251(a). Malloy, 
    568 F.3d at
    175–76. Most prosecutions involving this subset
    include performers that are undoubtedly children rather than
    adults that appear to be young. 
    Id. at 176
    . In fact, producers are
    already required to verify the ages of performers. See 
    18 U.S.C. § 2257
    (b)(1) (requiring producers to “ascertain . . . the
    performer’s name and date of birth”).
    Even if interpreting § 2251(a) to preclude mistake-of-
    age evidence chills some protected speech, the risk is
    significantly outweighed by the Government’s compelling
    interest in protecting children from child pornography.
    “[S]afeguarding the physical and psychological well-being” of
    children is a compelling government interest. Globe
    Newspaper Co. v. Superior Court, 
    457 U.S. 596
    , 607 (1982).

    Regardless, Kantor is of limited applicability to the
    issue at hand in this case. Kantor involved the production of a
    non-obscene film and was decided six years prior to the
    Supreme Court’s X-Citement Video decision. Kantor, 
    858 F.2d at 538
     (“[N]o one claims that [the film] is obscene; the film
    would therefore enjoy the protection of the [F]irst
    [A]mendment were it not for its depiction of a minor.”).
    17
    Here, Tyson recorded a video of the underage victim
    performing oral sex on him. Section § 2251(a) was enacted
    precisely to protect children from the conduct Tyson engaged
    in. After all, “[a] democratic society rests, for its continuance,
    upon the healthy, well-rounded growth of young people into
    full maturity as citizens.” Prince v. Massachusetts, 
    321 U.S. 158
    , 168 (1944).
    We hold that mistake of age is not a defense to § 2251(a)
    because knowledge is not an element of the offense. The statute
    also does not contain an affirmative mistake-of-age defense,
    and such a defense is not mandated by the Constitution.
    Therefore, the District Court did not err in excluding mistake-
    of-age evidence.
    IV.
    Accordingly, for the reasons stated above, we will
    affirm the District Court’s grant of the Government’s motion
    in limine precluding mistake-of-age evidence.
