D was sheriff of St. Charles Parish. D was sued by seven plaintiffs under 42 U.S.C. §§ 1981 and 1983 for alleged violations of the First and Fourteenth Amendments.

The basis of each plaintiff’s claims differed, but all claimed a violation of their First Amendment rights. Six of the seven alleged that D terminated them for their refusal to support him in his reelection bid. Three alleged racial discrimination. A remaining deputy alleged racial discrimination and retaliation for filing a workers' compensation claim. D filed a motion to sever under Rule 20(a). D also moved for separate trials under 42(b).
