Fernando Patino, Texas prisoner # 1153575, appeals from the dismissal of his 28 U.S.C. § 2254 petition challenging his murder conviction. This court granted a certificate of appealability on the issue whether the district court erred by dismissing Patino’s claims that prospective jurors James Estes and John Grimland were biased and should have been excused for cause.

A federal court must give deference to a state habeas court’s determination of the merits of the prisoner’s claims, unless the state decision “was contrary to, or involved an unreasonable application of, clearly established Federal law, as determined by the Supreme Court of the United States,” or “was based on an unreasonable determination of the facts in light of the evidence presented in the State court proceeding.” § 2254(d)(1) & (2). We review the district court’s findings of fact for clear error and issues of law de novo. Propes v. Quarterman, 573 F.3d 225, 227 (5th Cir. 2009), cert. denied, — U.S. -, 130 S.Ct. 3272, 176 L.Ed.2d 1188 (2010).

Even if Estes and Grimland were biased, Patino’s constitutional rights were *259 not violated because he used peremptory-challenges to strike both of them from jury service. See United States v. Martinez-Salazar, 528 U.S. 304, 307, 311, 120 S.Ct. 774, 145 L.Ed.2d 792 (2000); United States v. Sanchez-Hernandez, 507 F.3d 826, 830 (5th Cir. 2007). His arguments that his case falls within the exceptions to Martinez-Salazar are entirely conclusory. See Ross v. Estelle, 694 F.2d 1008, 1012 (5th Cir. 1983). He fails to show that he is entitled to habeas relief. See § 2254(d)(1) & (2); Harrington v. Richter, — U.S. -, 131 S.Ct. 770, 786-87, 178 L.Ed.2d 624 (2011).

AFFIRMED.
