In an exclusive interview with Breitbart News Friday, Republican presidential candidate Donald Trump said he expects to face Joe Biden rather than Democratic frontrunner Hillary Clinton in the presidential election.

When Breitbart asked him if he could see Biden leading the Democratic ticket, Trump said, "I think so," pointing to Hillary's "big league" problem of the ever-expanding private email scandal.

"I don’t see how she’s going to possibly be able to run," said the billionaire business mogul. "I think Hillary has got huge problems right now. Is she going to make it? I hear this thing is big league."

"Why did she do it? You use the server?" he asked. "Because they're always looking to go over the edge, whether it's Whitewater or anything else. They always want to go over the edge. I'm just looking at it saying what the hell was she doing? You know what she was doing. She was guarding from the president seeing what she was doing."

Calling Clinton's classified info breaches "ten times worse" than that of General David Petraeus, Trump predicted that her illegal conduct would ultimately be too much to overcome.

"It just looks like Hillary is going to not be able to run," he said. "It looks to me like that’s what’s going to happen. I think it’s unlikely if you look at what she’s done. What she’s done is ten times worse than what General Petraeus did—far more sensitive documents, top-of-the-line sensitive documents, far more of them. What she did is ten times worse. It destroyed him, so I don’t see how she’s going to possibly be able to run. It's pretty conclusive right now, too."
