The White House announced Monday Director of the Secret Service Randolph “Tex” Alles has been removed from his position, one day after Homeland Security Secretary Kirstjen Nielsen’s announced departure. As head of the Secret Service, he reported directly to Nielsen. Trump reportedly ordered Alles’s firing as part of a “purge” of top officials overseeing immigration policy, and spearheaded by White House senior adviser Stephen Miller. CNN is reporting Lee Francis Cissna, head of U.S. Citizenship and Immigration Services, and John Mitnick, general counsel of the Department of Homeland Security, could be next to leave the administration.
