Donald Trump: Bill Clinton Isn't 'Happy That I'm Running'

The real estate mogul dishes on a private call with the former president.

Real estate mogul Donald Trump on Thursday commented on a phone call that took place between himself and former President Bill Clinton earlier this year.

"Yeah, he called me," Trump told reporters after the first GOP presidential debate in Cleveland. "He's not happy that I'm running, I can tell you right now, because he thinks I'm the worst nightmare for Hillary."

The Washington Post reported on Wednesday that the two spoke over the phone in a private conversation, but that the election had not come up. Clinton reportedly "encouraged Trump’s efforts to play a larger role in the Republican Party." 

Trump didn't mince words about Democratic frontrunner Hillary Clinton, however.

"I would say this, nobody has spoken up this strongly of Hillary as I have," he said. "She should literally -- this is a criminal act that she has done, and all you have to do is ask General [David] Petraeus because you look at what happened to him, and that's peanuts compared to what Hillary did. Look, he understands that I'm Hillary's worst nightmare. He gets it."
