This is more flipping Trump off than it is an endorsement of Hillary Clinton. Cuban has been feuding with Donald Trump for years
Billionaire entrepreneur Mark Cuban endorsed Hillary Clinton on Saturday during a campaign event in Pittsburgh, telling CNN that he had decided Donald Trump had gone "bats--- crazy."
"Trump scares me," Cuban said after speaking on behalf of Clinton and Tim Kaine, her vice presidential nominee. "Donald, initially, I really hoped he would be something different, that as a businessperson, I thought there was an opportunity there. But then he went off the reservation and went bats--- crazy."
Cuban also said that he had talked to Trump before he endorsed Clinton and urged the real estate mogul-turned-candidate that at some point he had to adapt and learn policy.
"I told him directly, at some point you have to learn, at some point you have to read and that that job is all about uncertainty and if you don't do the work, that is not good for this country," Cuban said. "And he just doesn't do the work."
