PITTSBURGH -- Billionaire investor Mark Cuban on Saturday questioned Donald Trump's sanity, saying he has decided to vote for Hillary Clinton because the Republican presidential nominee has gone "off the reservation" and "crazy."
"Donald initially — I really hoped he would be something different, that as a businessperson, I thought there was an opportunity there," Cuban, the owner of the Dallas Mavericks and a star of "Shark Tank," told CNN while campaigning with Clinton in his hometown of Pittsburgh on Saturday. "But then he went off the reservation and went bat---- crazy."
Cuban, who once spoke fondly of Trump, also said that now Trump "scares me."
In recent weeks, Cuban met with Clinton's campaign chairman, John Podesta, to discuss a possible endorsement. An aide to Clinton said Cuban called on Thursday night, before Clinton's speech at the Democratic National Convention, to say he was in.
While campaigning with Clinton today, Cuban used the Pittsburgh slang word "jagoff" to express his dislike for Trump and said, "I’m ready to tell you that I'm ready to vote for a true leader. I'm ready to vote for the American dream. I'm ready to tell the world that I'm here to endorse Hillary Clinton."
Just last month, Cuban said on Fox Business, "There's a good chance I'll vote for Donald Trump" if Clinton picked as her running mate Massachusetts Sen. Elizabeth Warren. And in an interview with NBC's "Meet the Press" in May, Cuban said he was open to running for vice president with either Clinton or Trump. The billionaire described his political affiliation as "fiercely independent."
But it wasn't that long ago that Cuban was fully backing the Republican. Trump hosted one of his largest campaign rallies last September in Dallas at the American Airlines Center, home to Cuban's Mavericks of the NBA.
The previous July, Cuban said of Trump in a statement on Cyber Dust, a private-messaging app he created, "I have to honestly say he is probably the best thing to happen to politics in a long time."
"I don't care what his actual positions are. I don't care if he says the wrong thing," Cuban continued. "He says what's on his mind. He gives honest answers rather than prepared answers. This is more important than anything any candidate has done in years."
