MEMORANDUM **

Jeronimo Madriz-Reyna (“Madriz”) appeals his sentence of 188 months’ imprisonment, imposed following his guilty pleas to four counts of drug-related charges. We have jurisdiction pursuant to 18 U.S.C. § 8742 and 28 U.S.C. § 1291, and we affirm.

1. The district court found, after two proffer sessions, that Madriz’s testimony was implausible. Thus, the court further found that Madriz failed to meet the truthfulness requirement of 18 U.S.C. § 3558(f)(5), making him ineligible for safety-valve relief. We conclude that denial of safety-valve relief was proper because the district court’s finding that Madriz was untruthful was not clearly erroneous. See United States v. Alba-Flores, 577 F.3d 1104, 1107 (9th Cir. 2009).

2. The district court permitted Madriz’s co-defendant, Ulises Castellanos-Cisneros (“Castellanos”), to invoke his Fifth Amendment privilege against self-incrimination and not testify at Madriz’s sentencing proceeding, although Castella-nos had already been sentenced. Madriz contends that the district court erred and violated his Sixth Amendment right to compulsory process. We conclude, however, that any Sixth Amendment error was harmless, see United States v. Winn, 767 F.2d 527, 531 (9th Cir. 1985) (per curiam), because Madriz failed to show that Castel-lanos could offer any testimony that would have been helpful to Madriz.

The judgment of the district court is AFFIRMED.
