Tennessee Sen. Bob Corker, whom Trump considered for a Cabinet post, declared Thursday that "the president has not yet been able to demonstrate the stability nor some of the competence that he needs to" in dealing with crises. And Sen. Dan Sullivan of Alaska tweeted, "Anything less than complete & unambiguous condemnation of white supremacists, neo-Nazis and the KKK by the @POTUS is unacceptable. Period."
