Llanely Santos-Riviera, an illegal alien, was charged under the Hostage Taking Act, 18 U.S.C. § 1203, and convicted by-jury of one count of seizing, detaining, and threatening to injure a ten month old infant in order to compel the infant’s parents to pay a cash ransom for her release. The kidnapping occurred within the United States and the victim is a United States citizen. This appeal raises two issues: (1) whether the government was required to allege in the indictment and prove at trial, as essential elements of the offense, that the appellant was a foreign national and that the hostage taking or kidnapping at issue had some other “international aspect;” and (2) whether the Hostage Taking Act, as applied to Santos-Riviera, violated her Equal Protection rights because the statute discriminates on the basis of alien-age. We answer both questions in the negative and affirm.
I. BACKGROUND
The grand jury indictment charged that Santos-Riviera, within the Southern District of Texas, “did knowingly and intentionally seize, detain, threaten to injure and continue to detain Jocelyn Tehya Gar-rido in order to compel Ricardo Garrido and Maria Elliott Garrido to pay a cash ransom for the release of Jocelyn Tehya Garrido,” in violation of 18 U.S.C. §§ 2 and 1203. The indictment did not allege that Santos-Riviera was an illegal alien or- that the kidnapping involved the United States government or some other international aspect.
The evidence at trial showed that in 1997, Santos-Riviera illegally entered the United States from her home in Oaxaca, Mexico. In July of that year, she obtained employment in Brownsville, Texas caring for the two youngest children of Mr. and Mrs. Ricardo Garrido, Jr. While caring for the children, Santos-Riviera, either acting alone or aiding and abetting another person, 1 abducted the Garrido’s ten month old daughter and wrote a ransom note demanding that the Garridos pay $7000 for their daughter’s return. Santos-Riviera initially told the Garridos and law enforcement officers that she had been sexually assaulted by three men who then kidnapped the child. After additional investigation and questioning, during which officers pointed out several inconsistencies in appellant’s version of the events, Santos-Riviera confessed that she had fabricated the story about the three men and purported that a man named Antonio had forced her to participate in the abduction. A search for a man fitting the description of Antonio given by appellant was unsuccessful. Within a few hours of the abduction, the child was found alive in a wooded area behind the house where the Garridos were living. Santos-Riviera testified at trial that Antonio threatened her and forced her to give him the child, told her what to write in the ransom note, and told her to tell the Garridos that three men had raped her and taken the child. Appellant’s trial testimony, however, was inconsistent in several respects with her prior statements to the investigating officers, including her prior written statement that Antonio had offered her $2000 to participate in the abduction and promised to change her identity and move her to another city. The jury returned a verdict of guilty, and the district court sentenced Santos-Riviera to 144 months of imprisonment and five years of supervised release.
II. ANALYSIS
A. Sufficiency of the Indictment
Santos-Riviera contends that the indictment was defective because it failed to *369 allege that she was a non-national and that the kidnapping involved an additional “international aspect.” Although styled as a sufficiency claim, appellant actually poses a statutory construction question requiring us to determine the essential elements of an offense under the Hostage Taking Act, 1.e., whether the indictment must negate the exceptions set forth in § 1203(b)(2) to allege that the offender or victim is a non-national and whether the indictment must also allege an additional “international aspect.”
We analyze questions of statutory interpretation
de novo. See United States v. Fitch,
We begin our analysis with the essential elements of an offense under the Hostage Taking Act. The statute provides in relevant part:
(a) Except as provided in subsection (b) of this section, whoever, whether inside or outside the United States, seizes or detains and threatens to kill, to injure, or to continue to detain another person in order to compel a third person or a governmental organization to do or abstain from doing any act as an explicit or implicit condition for the release of the person detained, or attempts or conspires to do so, shall be punished by imprisonment for any term of years or for life and, if the death of any person results, shall be punished by death or life imprisonment.
(b)(1) It is not an offense under this section if the conduct required for the offense occurred outside the United States unless—
(A) the offender or the person seized or detained is a national of the United States;
(B) the offender is found in the United States; or
(C) the governmental organization sought to be compelled is the Government of the United States.
(2) It is not an offense under this section if the conduct required for the offense occurred inside the United States, each alleged offender and each person seized or detained are nationals of the United States, and each alleged offender is found in the United States, unless the governmental organization sought to be compelled is the Government of the United States.
18 U.S.C. § 1203 (emphasis added). At issue here is the construction and interplay of subsections (a) and (b). 2 Section 1203(a) delineates the prohibited conduct under the Act; it criminalizes the seizure or detention of a person in order to compel a third person or government organization to act or refrain from acting as a condition for release of the person detained. Section 1203(b) sets forth exceptions to the Act’s coverage, depending on whether the offense occurred within or without the United States. If the kidnapping occurred within the United States, as was the case here, subsection (b)(2) provides that the statute does not apply if both the victim and the offender are nationals of the United States and the party to be compelled is not the United States government. See § 1203(b)(2). In other words, application of the Hostage Taking Act to a domestic kidnapping not involving the United States government turns on the citizenship status of the offender or victim.
*370
Santos-Riviera contends that, in addition to the elements set forth in § 1203(a), the indictment should have further alleged that she was a non-national and that the kidnapping involved some “international aspect” or nexus beyond her status as an illegal alien. She essentially asserts that the
government has the
burden of negating the exceptions listed in § 1203(b). In support of her position, Santos-Riviera relies primarily upon language from our opinion in
United States v. Carrion-Caliz,
Santos-Riviera’s reliance on Carrion-Caliz is misplaced. In that case, while addressing a sufficiency of the evidence challenge to a conviction under § 1203, we, for the first time, set forth the essential elements of the offense. See id. at 222-23. We quoted the text of § 1203(a) and held:
by the plain terms of the statute, a conviction under the Hostage Taking Act requires the Government to show that the defendant 1) seized or detained another person, 2) threatened to kill, injure, or continue to detain that person, 3) with the purpose of compelling a third person or governmental entity to act in some way, or to refrain from acting in some way.
Id.
at 223;
accord United States v. Lin,
We then compared the Hostage Táking Act to the analogous federal kidnapping statute, 18 U.S.C. § 1201, in order to interpret the words “seizes” and “detains” contained in § 1203(a).
See Carrion-Caliz,
Second, our interpretation of the Hostage Taking Act is consistent with the well-established rule of criminal statutory construction that an exception set forth in a distinct clause or provision should be
*371
construed as an affirmative defense and not as an essential element of the crime.
See McKelvey v. United States,
Applying the above principles, this court and other circuits have interpreted similarly structured criminal statutes consistent with our reading of the Hostage Taking Act.
See United States v. Gonzales,
Finally, we disagree with Santos-Riviera’s assertion that our recent decision in
United States v. Adams,
B. Sufficiency of the Evidenoe
Santos-Riviera makes a related claim that the evidence was insufficient to support her conviction because the Government failed to prove that her offense involved the United States government or had an international aspect other than her status as an illegal alien. She does not dispute that the evidence was sufficient to establish all of the elements set forth in § 1203(a) and to prove that she was not a national of the United States. Having held that the Government does not have the burden to negate the exception set forth in § 1203(b)(2) and that it is not an element of the offense that the kidnapping or hostage taking involve some additional international aspect or nexus, we naturally reject Santos-Riviera’s sufficiency challenge.
C. Equal Protection Claim
Santos-Riviera also raises a constitutional challenge to the Hostage Taking Act. She argues that, as applied, the Act violates her equal protection rights because it discriminates on the basis of alien-age,
i.e.,
the statute provides for federal prosecution of a purely local kidnapping when the defendant is an alien, whereas a United States citizen or national would not be subject to federal prosecution and the corresponding harsher federal penalties for the same conduct. The constitutionality of the Hostage Taking Act is a matter of first impression in this Circuit. The Second and Ninth Circuits, however, have both considered the issue and held that the Act does not violate the equal protection component of the Fifth Amendment Due Process clause.
See United States v. Lue,
We review the constitutionality of a federal statute
de novo. See United States v. Rasco,
We reject appellant’s erroneous suggestion that both state and federal statutes that classify based on alienage are subject to strict scrutiny. Appellant’s reliance on
Adarand Constructors, Inc. v. Pena,
We apply the deferential rational basis test to federal statutes that classify based on alienage and will uphold the statute if it is rationally related to a legitimate government interest.
See Mathews,
The legislative history of the Hostage Taking Act demonstrates that the Act was passed to address legitimate foreign policy concerns. Indeed, as we noted in Car-riorir-Caliz:
Congress enacted the Hostage Taking Act to meet its obligations as a signatory state to the Hostage Taking Convention. Article 5 of that treaty required signatory states to extend jurisdiction over hijacking committed outside the United States when the offender was a citizen of the states, or “present” in the state. It also provided states with the discretion to assert jurisdiction when their nationals were taken hostage. Congress’ voluntary decision to adopt this permissive basis of jurisdiction underscores its intent to exercise broad jurisdiction over any offender who threatens American nationals.
Carrion-Caliz,
The crux of Santos-Riviera’s argument is that, although there are legitimate governmental interests in extending jurisdiction over extraterritorial crimes, curtailing terrorism, and enforcing treaties, prosecuting a hostage taking case for a domestic kidnapping based solely on the perpetrator’s alienage achieves none of these governmental interests. The Second Circuit considered and rejected this argument in Lue. The court explained:
We recognize that in the Hostage Taking Act Congress employs the classification of alienage to proscribe conduct which may not always bear a direct relationship to the Act’s principal object of stemming acts of terrorism, and that at some point a classification of this sort may have a “relationship to [the] asserted goal [which] is so attenuated as to render the distinction arbitrary or irrational.” However, in this instance, Congress rationally concluded that a hostage taking within our jurisdiction involving a noncitizen is sufficiently likely to involve matters implicating foreign policy or immigration concerns as to warrant a federal criminal proscription. The connection between the act and its purpose is not so attenuated as to fail to meet the rational-basis standard.
*374
AFFIRMED.
Notes
. The defense theory below was that a man known only as Antonio coerced appellant into participating in the abduction. The jury, however, clearly rejected the coercion defense by finding Santos-Riviera guilty. The jury necessarily either entirely rejected Santos-Riviera's testimony concerning Antonio's participation in the abduction and determined that she acted alone, or the jury determined that Santos-Riviera knowingly and willingly aided and abetted Antonio in the commission of the offense.
. Section 1203(c) is not at issue in this appeal.
. By way of comparison to the Hostage Taking, Act, we note that the federal machine gun statute is similarly structured and provides:
(o )(1) Except as provided in paragraph (2), it shall be unlawful for any person to transfer or possess a machinegun.
(2) This subsection does not apply with respect to—
(A) a transfer to or by, or possession by or under the authority of, the United States or any department or agency thereof ...; or
(B) any lawful transfer or lawful possession of a machinegun that was lawfully possessed before the date this subsection takes effect.
18 U.S.C. § 922(o) (emphasis added).
. Section 20.21 provides in relevant part:
Migratory birds on which open seasons are prescribed in this part may be taken by any method except those prohibited in this section. No person shall take migratory game birds:
(a)
(i) By the aid of bailing, or on or over any baited area.... However, nothing in this paragraph shall prohibit:
(1) The taking of all migratory game birds, including waterfowl, on or over standing crops, flooded standing crops (including aquatics), flooded harvested croplands, grain crops properly shocked on the field where grown, or grains found scattered solely as the result of normal agricultural planting or harvesting; and
(2) The taking of all migratory game birds,’ except waterfowl, on or over any lands where shelled, shucked, or unshucked corn, wheat or other grain, salt, or other feed has been distributed or scattered as the result of bona fide agricultural operations or procedures . ..;
