Todd Maupin appeals his 240-month and 480-month sentences imposed following his guilty plea to two child pornography counts, both in violation of 18 U.S.C. § 2252A. Maupin asserts the district court erred in enhancing his sentences based on its determination that a 1991 nolo contendere plea with adjudication withheld to Florida child pornography charges was a prior conviction warranting a sentencing enhancement under 18 U.S.C. § 2252A(b)(l) and (b)(2). We conclude the district court did not err in enhancing Maupin’s sentences, and affirm.
I. BACKGROUND
Maupin was charged with knowingly possessing material containing images of child pornography in violation of 18 U.S.C. § 2252A(a)(5)(B), (b)(2) (Count I), and knowingly and intentionally receiving and attempting to receive child pornography materials shipped and transported through interstate and foreign commerce by computer via the Internet in violation of 18 *1305 U.S.C. § 2252A(a)(2)(B), (b)(1) (Count II). Maupin pled guilty to both counts.
The Government filed a notice of sentencing enhancement. In the notice, the Government stated Maupin was convicted in 1991 of possession of child pornography, in violation of Section 847.012 of the Florida Statutes. The Government noted the state court withheld adjudication and sentenced Maupin to five years’ probation. Based on this previous conviction, the Government intended to seek enhancement of his sentence pursuant to 18 U.S.C. § 2252A(b)(l) and (b)(2).
The probation office prepared a presen-tence investigation report (PSI). After grouping the counts pursuant to U.S.S.G. § 3D1.2(d), the probation office assigned Maupin a base offense level of 22 pursuant to U.S.S.G. § 2G2.2. Because the offense involved children under 12 years of age, sadistic and masochistic conduct, use of computer, and more than 600 images, the offense level was increased 13 levels under U.S.S.G. § 2G2.2(b) to yield an adjusted offense level of 35. The offense level was then decreased by 3 levels for acceptance of responsibility pursuant to U.S.S.G. § 3E1.1 to yield a total offense level of 32. Maupin’s criminal history category was I. With a criminal history category of I and a total offense level of 32, Maupin’s Guidelines range was 121 to 151 months’ imprisonment. Maupin’s range was increased to 180 months’ imprisonment, however, pursuant to U.S.S.G. § 5Gl.l(b) based upon the statutory mandatory minimum term required for Count II.
Relying on the 1991 Florida nolo conten-dere plea with adjudication withheld as a prior conviction warranting a statutory sentencing enhancement, the probation office identified the penalty ranges to be 10 to 20 years’ imprisonment pursuant to 18 U.S.C. § 2252A(b)(2) for Count I, and 15 to 40 years’ imprisonment pursuant to 18 U.S.C. § 2252A(b)(l) for Count II. The probation office recommended concurrent, statutory-maximum sentences (240 months and 480 months, respectively) with a supervised release term of life for each count.
Maupin objected to the PSI by letter. He objected to enhancement of his sentence based on the 1991 nolo contendere plea with adjudication withheld. Maupin asserted 18 U.S.C. § 2252A(b)(l)’s and (b)(2)’s use of the phrase “under laws of any State” meant Florida law should determine whether the nolo contendere plea constituted a prior conviction. He claimed it would not be considered a prior conviction under Florida law.
The district court determined the PSI was accurate and considered its findings in its imposition of a sentence. The district court stated it had consulted the Sentencing Guidelines before calculating the advisory range. The court found aggravating circumstances existed pursuant to 18 U.S.C. § 3553(b)(2)(A)(i) that were not adequately accounted for by the Guidelines because the number of child pornography images exceeded 110,000. Considering the factors of 18 U.S.C. § 3553(a) — particularly the seriousness and duration of the offense, the number and vulnerability of the victims, Maupin’s prior misconduct, promotion of respect of the law and protection of society, and provision of just punishment and deterrence — the court found that only a lengthy sentence was adequate. Therefore, the court imposed the maximum penalties and sentenced Maupin to 240 months’ imprisonment for Count I and 480 months’ imprisonment for Count II, to run concurrently, followed by supervised release terms of life in both sentences. Maupin now appeals his sentences.
II. DISCUSSION
Maupin emphasizes § 2252A(b)(l) and (b)(2) require a defendant to have a *1306 prior conviction “under the laws of any State” before a sentence may be enhanced. Because the prepositional phrase “under the laws of any State” modifies the term “conviction,” Maupin argues state law must determine whether or not a nolo contendere plea with adjudication withheld should be considered a conviction. Maupin contends Florida law does not consider entry of a nolo contendere plea with adjudication withheld to be a conviction. Even if this conclusion is not compelled by the statutory language, Maupin argues his interpretation is a rational construction, not prohibited by Congress’s language, and consistent with the rule of lenity.
We review
de novo
questions of statutory interpretation.
United States v. Johnson,
(b)(1) Whoever violates, or attempts or conspires to violate, paragraph (1), (2), (3), (4), or (6) of subsection (a) shall be fined under this title and imprisoned not less than 5 years and not more than 20 years, but, if such person has a prior conviction under this chapter ... or under the laws of any State relating to ... child pornography ... such person shall be fined under this title and imprisoned for not less than 15 years nor more than 40 years.
(2) Whoever violates, or attempts or conspires to violate, subsection (a)(5) shall be fined under this title or imprisoned not more than 10 years, or both, but, if such person has a prior conviction under this chapter ... or under the laws of any State relating to ... child pornography, such person shall be fined under this title and imprisoned for not less than 10 years nor more than 20 years.
18 U.S.C. § 2252A(b)(l),(2) (emphasis added). Neither we nor the Supreme Court has addressed the specific issue of whether a plea of
nolo contendere
with adjudication withheld constitutes a prior conviction for purposes of § 2252A. The Eighth Circuit, however, relied on federal law in concluding entry of a
nolo contendere
plea in Florida state court to committing lewd and lascivious acts upon a child under 16 with adjudication withheld constituted a prior conviction under 18 U.S.C. § 2252A(b)(2).
United States v. Storer,
Although we have not decided this exact issue, our cases interpreting similar statutory language are instructive. In
United States v. Mejias,
Mejias
is in accord with our other holdings that federal law generally determines whether an offense constitutes a prior conviction.
See, e.g., United States v. Anderson,
In
United States v. Willis,
Unlike
Willis,
the statute at issue here does not provide the jurisdiction in which the proceedings were held should determine whether an offense constitutes a prior conviction.
See id.
at 970. Instead, it involves a statutory sentencing enhancement similar to the statutory enhancement considered in
Mejias. See Mejias,
Additionally, we are not persuaded by Maupin’s rule of lenity argument. “The simple existence of some statutory ambiguity ... is not sufficient to warrant application of that rule, for most statutes are ambiguous to some degree.”
Muscarello v. United States,
*1308 III. CONCLUSION
The district court did not err in enhancing Maupin’s sentences pursuant to 18 U.S.C. § 2252A(b)(l) and (b)(2), based on a 1991 nolo contendere plea with adjudication withheld to Florida charges related to possession of child pornography. Accordingly, we affirm Maupin’s sentences.
AFFIRMED.
