The Federal Public Defender appointed to represent Hector Ruiz has moved for leave to withdraw and has filed a brief in accordance with Anders v. California, 386 U.S. 738, 87 S.Ct. 1396, 18 L.Ed.2d 493 (1967), and United States v. Flores, 632 F.3d 229 (5th Cir. 2011). Ruiz has filed a response. We have reviewed counsel’s brief and the relevant portions of the record reflected therein, as well as Ruiz’s response. We concur with counsel’s assessment that the appeal presents no nonfrivolous issue for appellate review. Ruiz’s pro se response arguing that counsel was ineffective for not demonstrating the invalidity of a prior conviction does not present a nonfrivolous issue. Accordingly, the motion for leave to withdraw is GRANTED, counsel is excused from further responsibilities herein, and the APPEAL IS DISMISSED. See 5th Cir. R. 42.2.
