The ex-fixer for Donald Trump said he personally warned Giuliani that he would eventually end up on the short end of the stick because Trump “doesn’t care about anyone or anything.” “He’s been involved in some very, very shady stuff and now it’s all gonna come out,” Cohen said on CNN. Sounding like he’s regained some of his New York swagger after a humiliating stint in prison, Cohen explosively predicted that the former mayor will eventually flip on his ex-boss and cooperate with the feds. “Do I think Rudy will give up Donald in a heartbeat? Absolutely,” said Cohen. As a former U.S. attorney for the Southern District of New York, Giuliani knows better than anyone that he is facing the legal equivalent of a ton of bricks, Cohen said. “He knows exactly what’s coming down the road and he knows how to avoid it,” Cohen said. “He’s going to start talking:1,2,3.″ Cohen suggested that the raids may help the feds dig up even more damaging lines of investigation, possibly involving the former president, his relatives or other cronies in the “garbage can orbit of Donald Trump.” “Rudy’s an idiot, he drinks too much and he acts in an erratic manner,” Cohen said.
