@thewrap: #DonaldTrump’s pattern of concerning and provocative behavior continued at his Friday rally in Milwaukee, Wisconsin, as a furious Trump complained about the height of his microphone for four minutes and asked the audience if they wanted to see him “knock the hell out of people backstage” for not getting the mic properly set up. Oh, and while he did this, he appeared to mime an oral sex act as he showed how he had to adjust to reach the microphone that had been set up too low.
