PER CURIAM. Claude L. Rivers, Sr., appeals from the dismissal of his civil rights suits alleging claims under the Racketeer Influenced and Corrupt Organizations Act (“RICO”); 18 U.S.C. § 1964(c); the Hobbs Act, 18 U.S.C. § 1951; 42 U.S.C. § 1983; the Due Process Clause; and the Equal Protection Clause. The district court dismissed the complaint as frivolous. As a preliminary matter, Rivers has inadequately briefed his claims under 42 U.S.C. § 1988, and he has failed to brief his claims concerning the defendants’ alleged distribution of marijuana or his claims arising under state law.
Accordingly, those claims are deemed abandoned. See Yohey v. Collins, 985 F.2d 222, 224—25 (5th Cir.1993); see also Fed. R.App. P. 28(a)(9). We find no merit in the argument that the district court should have ruled on Rivers’s motion to recuse because the case was transferred from the district judge who was the subject of the motion. See 28 U.S.C. §§ 144 and 455. Rivers argues that he adequately pleaded his RICO claims because he alleged the predicate acts of mail fraud and extortion.
We conclude, however, that Rivers’s complaint fails to allege sufficiently a pattern of racketeering activity connected to the acquisition, establishment, conduct, or control of an enterprise. See Elliott v. Foufas, 867 F.2d 877, 880 (5th Cir.1989); Manax v. McNamara, 842 F.2d 808, 811 (5th Cir.1988). Rivers’s motion to transfer the appeal to the United States Supreme Court is DENIED. AFFIRMED; MOTION DENIED. Pursuant to 5th Cir. R. 47.5, the court has determined that this opinion should not be published and is not precedent except under the limited circumstances set forth in 5th Cir. R. 47.5.4.
