Steve Bannon, the CEO of Donald Trump's campaign, was charged with injuring his former wife in a domestic violence case when they were married in the 1990s, according to California court documents and news reports.

The case was later dismissed, but it stemmed from an argument on New Year’s Day in 1996 over finances, Politico reports.

During the argument, Bannon grabbed his then-wife, Mary Louise Piccard, "by the throat and arm" and threatened "to take the girls and leave," according to divorce documents obtained by the New York Post.

Bannon, 62, is on leave as executive chairman of Breitbart News to head Trump's campaign.

The couple married three days before their twin daughters were born in 1995. They divorced after the domestic case was dismissed in August 1996, Politico reports.

Police in Santa Monica, Calif., were called, and they filed a report and took pictures of Piccard's injuries, according to her statement in the case.

"I took the phone to call the police and he grabbed the phone away from me throwing it across the room, and breaking it as he [was] screaming that I was a 'crazy f---ing c--t!" the document said.

Bannon pleaded not guilty to the criminal charges filed against him in the case, Politico reports.

The case was dismissed because of lack of witnesses.

In her declaration, Piccard said that Bannon had hired a lawyer who had "threatened" her — saying that she "would have no money [and] no way to support the children" if the case went to trial, The New York Times reports.

Bannon then told Piccard to leave town, she claimed in the document.

He said that "if I wasn’t in town they couldn’t serve me and I wouldn’t have to go to court," she said, according to the Post. "He also told me that if I went to court he and his attorney would make sure that I would be the one who was guilty.

"I was told that I could go anywhere in the world."

Piccard left for two weeks before Bannon's attorney said she could return, according to the document.

"Because I was not present at the trial, the case was dismissed," she said.

Picccard also said that Bannon had told her that earlier in the relationship that he would marry her only if the twins were "normal."

She was his girlfriend and pregnant at the time, according to the Post.

They married on April 14, 1995. Their daughters were born three days later.

Piccard declined to comment to the Post. "I have no comment and neither does my daughter," she said.

Alexandra Preate, a Bannon spokeswoman, told Politico: "The bottom line is he has a great relationship with the twins, he has a great relationship with the ex-wife, he still supports them."
