Adrian Steven Morin appeals the judgment of the district court 1 entered after he pleaded guilty to conspiracy to distribute and to possess with intent to distribute in excess of 500 grams of a substance containing methamphetamine in violation of 21 U.S.C. §§ 841(a)(1). and 846. He argues that his sentence violated the Ex Post Facto Clause and the Fifth and Sixth Amendments of the United States Constitution. He also asserts that the district court made numerous errors in calculating the applicable range under the United States Sentencing Guidelines (the “Guidelines”), and that the district court improperly considered certain statements while calculating that range. We affirm.
I.
Morin was one of thirteen defendants charged in a fifty-count indictment. Morin entered into a plea agreement on August 30, 2004. The plea agreement required the government to dismiss five counts against Morin, but allowed each party to argue any issue related to Morin’s sentence. A sentencing hearing was held on December 10, 2004, and, because of issues related to
Blakely v. Washington,
The district court concluded that Morin’s base offense under the Guidelines was a 38. It added a two-level increase for possession of a firearm and a four-level increase for being a leader, organizer or manager. U.S.S.G. §§ 2Dl.l(b), 3Bl.l(a). It also allowed a three-level reduction for acceptance of responsibility. U.S.S.G. § 3C1.1. 'The district court determined that with a net offense level of 41 and a criminal history of category I, the applicable Guidelines range was 324 to 405 months. It stated that the Guidelines were advisory and that it considered the sentencing factors laid out in 18 U.S.C. 3553(a). The district court then varied 60 months from the low end of the Guidelines range and sentenced ’ Morin to 264 months, 2 five years supervised release, and a $100 special assessment. Morin filed a timely appeal.
II.
Morin appeals a number of aspects of his sentence. He argues that, because of uncertainty in the law at the time -he entered his plea, his sentence was imposed in violation of the Fifth and Sixth Amendments and the Ex Post Facto Clause of the United States Constitution. He also asserts that the district court made the following errors in sentencing: improperly considering certain statements made by Morin, finding that Morin possessed a dangerous weapon, determining that Morin *780 was an organizer or leader, and erroneously calculating the drug quantity attributed to Morin. We address these arguments in turn.
Booker Arguments
Morin entered a plea agreement post-
Blakely
and pr
e-Booker,
but was sentenced
post-Booker.
Because of the timing of his plea, Morin contends that it was improper for the district court to impose sentence enhancements that are permissible under
Booker
but which he claims were impermissible under
Blakely.
He specifically claims that his sentence violates the Fifth and Sixth Amendments and the Ex Post Facto Clause. These arguments are without merit. We have previously rejected the argument that when a plea was entered into
post-Blakely
and pr
e-Booker,
sentence enhancements cannot be based on facts found by a judge.
United States v. Salter,
Morin also argues that his sentence was in violation of Booker because the district court did not properly treat the Guidelines as advisory. This argument is without merit. Although the district court acknowledged the importance of the Guidelines, it stated that it treated the Guidelines as advisory. The record indicates that the district court considered other section 3553(a) factors. Additionally, the district court sentenced Morin below the low end of the recommended Guidelines range.
Sentence Enhancements
In calculating Morin’s sentence, the district court considered a variety of evidence including a - tape-recorded confession of Morin and jailhouse recordings of several of Morin’s phone calls. Morin asserts that the confession was improperly obtained after he requested counsel. Morin also asserts that the jailhouse conversations were communications obtained without a warrant and thus are inadmissible.
The district court rejected Morin’s first argument because it believed Morin’s testimony that he requested an attorney was not credible. “A district court’s assessment of a witness’s credibility is almost never clear error given that court’s comparative advantage at evaluating credibility.”
United States v. Killingsworth,
The district court rejected Morin’s second argument because it found that Morin impliedly consented to the taping of his jailhouse calls.
United States v. Horr,
The district court relied on Morin’s statements described above, as well as additional evidence, and imposed a two-level increase for possession of a firearm and a four-level increase for being a leader, organizer, or manager. U.S.S.G. §§ 2Dl.l(b), 3Bl.l(a). We review each of these enhancements for clear error.
United States v. Johnson,
“As a ‘general proposition, a sentencing judge may appropriately conduct an inquiry broad in scope, largely unlimited either as to the kind of information he [or she] may consider, or the source from which it may come.’ ”
United States v. Wallace,
With respect to the organizer or leader enhancement, Morin does not dispute that the conspiracy involved more than five participants and was extensive. Rather, he claims he was not an organizer or leader. We have said that those terms are to be interpreted broadly.
United States v. Thompson,
We review the district court’s factual findings of a drug quantity for clear error.
United States v. Johnston,
III.
For the foregoing reasons, we affirm the sentence imposed by the district court.
Notes
. The Honorable Ralph R. Erickson, United States District Judge for the District of North Dakota.
. This sentence was to run concurrently with another sentence previously imposed for a separate conviction.
. Because we agree with the district court that these statements would have been admissible at trial, we need not address the government's argument that Morin waived any right to object to these statements at sentencing by entering a guilty plea.
. Morin argues that the district court did not properly distinguish between the four-level enhancement for being an organizer or leader under U.S.S.G. § 3Bl.l(a) and the three-level enhancement for being a manager or supervisor under U.S.S.G. § 3Bl.l(b). After a careful review of the record we are confident that the district court correctly understood and applied U.S.S.G. § 3Bl.l(a).
