Donald Trump's new campaign CEO is already under fire after reports revealed an old domestic violence arrest and a sketchy voter registration. Courtney Gross takes a closer look at the leader of the Trump campaign.

Not even two weeks on the job, and Steve Bannon is already causing some problems.

The head of Breitbart News, the conservative website peddling salacious headlines, has a domestic violence arrest in his past.

In 1996, he was accused of domestic violence by his then-wife in Santa Monica, California. He pleaded not guilty, and the charges were dropped.

A spokeswoman told us Bannon himself was never involved in the case. His attorney handled it, and she added he has a great relationship with his ex-wife and twins.

It's unclear whether Donald Trump knew anything about it.

"I don't know what he was aware of with respect to a 20-year-old claim where the charges were dropped," Kellyanne Conway, Trump's campaign manager, said on Good Morning America.

On Friday, Bannon was also found to be registered to vote at a Florida address that is vacant.

To some, Bannon was a strange pick to be the CEO of the Trump campaign. He has no history of running this kind of campaign at all.

"These are all the kind of risks you take when you decide to throw the script out and bring in somebody at this stage of a presidential campaign with no campaign or political experience. It's a recipe for disaster and distraction, and that's what it's delivering," said John Avlon of The Daily Beast.

Maybe because Bannon is known as a provocateur whose site is required reading for what's known as the "alt-right."

"How would I define the alt-right? Nativist. White supremacist," said Brett Gary of New York University. "They are political agitators, right, and they are activists who sort of actively try to derail or undermine traditional left liberal organizations."

This provided ammunition for an entire speech by Hillary Clinton this week, who went after Trump and Bannon for sympathizing with white supremacists. Her vice president, Tim Kaine, reiterated that line of attack on Friday.

"Ku Klux Klan values, David Duke values, Donald Trump values are not American values," Kaine said.

The Trump campaign was not weighing in. They did not respond to our request for comment.
