Peter Okechukwu Ajaegbu, federal prisoner #24189-077, moves this court for leave to proceed in forma pauperis (IFP) in his appeal from the district court’s denial of his civil complaint under the National Labor Relations Act (NLRA) against an employee of the Federal Prison Industries (FPI). The district court dismissed Ajaeg-bu’s suit for failure to state a claim, pursuant to 28 U.S.C. § 1915(e)(2)(B)(ii), finding that only employers may be sued under the NLRA and that the FPI did not qualify as an employer under the NLRA.

In his brief, Ajaegbu argues that his constitutional rights have been violated, but he fails to brief any argument regarding the district court’s certification decision or, in particular, its dismissal of his *500 lawsuit for failure to state a claim upon which relief can be granted. Although we liberally construe pro se briefs, see Haines v. Kerner, 404 U.S. 519, 520, 92 S.Ct. 594, 30 L.Ed.2d 652 (1972), even pro se litigants must brief arguments in order to preserve them. Yohey v. Collins, 985 F.2d 222, 224-25 (5th Cir. 1993). By failing to discuss the district court’s rationale for dismissing his complaint, Ajaegbu has abandoned the issue, and it is the same as if he had not appealed the judgment. See Brinkmann v. Dallas County Deputy Sheriff Abner, 813 F.2d 744, 748 (5th Cir. 1987). Because Ajaegbu has failed to demonstrate that he will raise a nonfrivo-lous issue on appeal, his motion to proceed IFP is denied. See Fed. R.App. P. 24(a); Carson v. Polley, 689 F.2d 562, 586 (5th Cir. 1982). This appeal is without merit and is dismissed as frivolous. See Howard v. King, 707 F.2d 215, 219-20 (5th Cir. 1983); 5th Cir. R. 42.2.
