Unpublished opinions are not binding precedent in this circuit.

Eugene Peter Schuler seeks to appeal the district court’s order denying his second Fed. R. Civ. P. 60(b) motion for reconsideration of the district court’s order denying relief on his 28 U.S.C. § 2254 (2012) petition. We deny Schuler’s motion for a certificate of appealability, dismiss the appeal, and deny authorization to file a successive § 2254 petition.

Because Schuler’s Rule 60(b) motion contains both a claim challenging the integrity of the federal habeas proceeding and a reiteration of his substantive habeas claims, it is a mixed Rule 60(b) motion/§ 2254 petition. See United States v. Winestock, 340 F.3d 200, 206-08 (4th Cir. 2003). To the extent Schuler presents a true Rule 60(b) motion, we deny a certificate of appealability and dismiss this portion of the appeal. See 28 U.S.C. § 2253(c) (2012); Reid v. Angelone, 369 F.3d 363, 369 (4th Cir. 2004) (holding true Rule 60(b) motion is subject to certificate of appeala-bility requirement), abrogated on other grounds by United States v. McRae, 793 F.3d 392, 399-400 & n.7 (4th Cir. 2015).

To the extent Schuler seeks to appeal the district court’s denial of his unauthorized successive § 2254 claims, we conclude that the district court lacked jurisdiction to review any such claim. 28 U.S.C. § 2244(b) (2012). And construing Schuler’s notice of appeal and informal brief as a motion for authorization to file a second or successive § 2254 petition, Winestock, 340 F.3d at 208, we determine that Schuler has not shown entitlement to authorization, as his informal brief merely argues the same claims he raised in his § 2254 petition. See 28 U.S.C. § 2244(b)(1) (providing that any “claim presented in a second or successive habeas corpus application under section 2254 that was presented in a prior application shall be dismissed”). Accordingly, we also deny authorization to file a successive § 2254. petition.

We dispense with oral argument because the facts and legal contentions are adequately presented in the materials before this court and argument would not aid the decisional process.
