Benedict Emesowum appeals the dismissal without an evidentiary hearing of his 42 U.S.C. § 1983 suit arising from his arrest at a bus terminal and claiming that the defendants violated his constitutional rights in several regards. He does not challenge the district court’s several motion rulings contained in the order at issue and has, therefore, abandoned any such challenges. See Yohey v. Collins, 985 F.2d 222, 225 (5th Cir. 1993) (recognizing that even pro se litigants must brief arguments to preserve them); Fed. R. App. P. 28(a)(8).

We review the dismissal for failure to state a claim de novo, applying the standard used to review a dismissal under Federal Rule of Civil Procedure 12(b)(6). Hart v. Hairston, 343 F.3d 762, 763-64 (5th Cir. 2003). Emesowum, whose brief consists of conclusory assertions and is entirely devoid of record citations, fails to show that the district court erred. See id.

AFFIRMED.
