Republican Sen. Bob Corker reignited his feud with Donald Trump on Tuesday.Though the back and forth between Corker and Trump goes back months, the Tennessee senator seemed to strike a cord when he said the president should let Congress handle tax reform. In response, Trump tweeted that Corker “couldn’t get elected dog catcher in Tennessee.”Later in the day, when asked whether he regretted voting for Trump, Corker said “Well let’s just put it this way, I would not do that again.”Few Republicans have gone after Trump like Corker.
