MEMORANDUM **

Jeffrey Alan Smith appeals the district court’s denial of his petition for habeas relief under 28 U.S.C. § 2254 from convictions of first degree murder with special circumstances, first degree burglary, and attempted robbery. We affirm.

1. Smith argues that the trial court violated Bruton when it admitted an out-of-court statement by his non-testifying co-defendant, Mark Taffolla, which directly implicated Smith. See Bruton v. United States, 391 U.S. 123, 88 S.Ct. 1620, 20 L.Ed.2d 476 (1968). Bruton, however, applies to statements that violate the Confrontation Clause of the Sixth Amendment. Id. at 126, 88 S.Ct. 1620. In Crawford v. Washington, 541 U.S. 36, 51, 124 S.Ct. 1354, 158 L.Ed.2d 177 (2004), the United States Supreme Court held that the Confrontation Clause only bars “testimonial” out-of-court statements. Although Crawford did not establish a singular definition of “testimonial,” the Court explained that “[a]n accuser who makes a formal statement to government officers bears testimony in a sense that a person who makes a casual remark to an acquaintance does not.” Id. The disputed statement — an account of the crime Taffolla gave to his girlfriend in a motel room — was clearly not testimonial. Given that Bruton’s core holding relies on the Confrontation Clause, the California Court of Appeal’s decision was not “contrary to, [nor did it] involve[ ] an unreasonable application of, clearly established Federal law, as determined by *654 the Supreme Court of the United States.” See 28 U.S.C. § 2254(d)(1).

2. We decline to expand the Certificate of Appealability to incorporate Smith’s additional, related argument that admission of Taffolla’s statement violated his due process rights. Smith has not made “a substantial showing of the denial of a constitutional right.” See 28 U.S.C. § 2258(c)(2); 9th Cir. R. 22-1(e).

AFFIRMED.
