Per Curiam: * Kofi Obeng, proceeding pro se, appeals the district court’s dismissal of his civil action for lack of subject matter jurisdiction. Although pro se filings are afforded liberal construction, even pro se litigants must brief arguments in order to preserve them. Yohey v. Collins, 985 F.2d 222, 225 (5th Cir. 1993).

No. 25-10214

determination that it lacked subject matter jurisdiction, Obeng has abandoned any possible challenge to the dismissal of his civil action. See Brinkmann v. Dallas Cnty. Deputy Sheriff Abner, 813 F.2d 744, 748 (5th Cir. 1987). In any event, the district court did not err in dismissing his case for lack of subject matter jurisdiction. See 28 U.S.C. §§ 1331, 1332; Arbaugh v. Y&H Corp., 546 U.S. 500, 513 (2006).

In light of the foregoing, the judgment of the district court is AFFIRMED.
