The underlying suit commenced when Plaintiff-Appellant Henry C. Adams, Jr. filed suit in Texas state court to enjoin a foreclosure action and alleged violations of (1) the Texas Debt Collection Act, Chapter 392 of the Texas Finance Code, (2) the Texas Deceptive Trade Practices Act, § 17.41, et seq., of the Texas Business & Commerce Code, (3) negligent misrepresentation, and (4) wrongful foreclosure. Thereafter, the case was removed to federal court on the basis of federal question1 and diversity jurisdiction. The parties consented to proceed before a magistrate judge, with Adams appearing pro se. The magistrate judge afforded Adams two opportunities to amend his complaint in order to provide more factual details in support of his claims, but Adams failed to avail himself of these opportunities. The magistrate judge then dismissed Adams’s suit with prejudice under Rule 12(b)(6), on the basis that Adams had failed to state a claim.
Even a pro se appellant must set forth arguments and citations to legal authority. See Mapes v. Bishop, 541 F.3d 582, 584 (5th Cir.2008) (“Although pro se briefs are afforded liberal construction, even pro se litigants must brief arguments in order to preserve them.” (citations omitted)). While we interpret Adams’s brief liberally, see Haines v. Kerner, 404 U.S. 519, 520, 92 S.Ct. 594, 30 L.Ed.2d 652 (1972), he has failed to argue any facts or set forth any authority which would allow us to overturn the decision of the district court. See Grant v. Cuellar, 59 F.3d 523, 525 (5th Cir.1995) (finding a pro se appellant’s brief insufficient in part because it “[did] not argue that the district court erred in any way.”). After reciting a litany of apparent facts, Adams makes one argument: that a “forensic audit report” reveals that the Defendants-Appellees have committed *527various violations of federal and Texas law. However, the purported forensic audit report was never introduced in the district court, and “[t]he court of appeals will not generally consider evidence or arguments that were not presented to the district court.” Dunbar v. Seger-Thomschitz, 615 F.3d 574, 576 (5th Cir.2010) (citing Nissho-Iwai American Corp. v. Kline, 845 F.2d 1300, 1307 (5th Cir.1988)).
Plaintiff-Appellant Adams has failed to address in any form or fashion the magistrate judge’s reasons for dismissing his case. Accordingly, the decision of the district court is hereby AFFIRMED.
