Donald Trump campaign manager Corey Lewandowski has been charged with assaulting a journalist at a campaign event.
Mr Lewandowski is charged with simple battery over his encounter with former Breitbart reporter Michelle Fields.
Police allege that on 8 March after a news conference in Florida, he grabbed her arm when she tried to ask Mr Trump a question, leaving a bruise.
Mr Lewandowski plans to plead not guilty, the Trump campaign said.
Police in Jupiter, Florida, where he was arrested, have released new footage of the alleged assault.
The security video appears to show him trying to pull Ms Fields out of the way as she walks alongside Mr Trump and tries to speak to him.
“Mr Lewandowksi is absolutely innocent of this charge,” the Trump statement said. “He is completely confident that he will be exonerated.”
Mr Trump himself has defended Mr Lewandowski on Twitter, saying the police footage shows there was “nothing there”.
He defend Mr Lewandowski later on Tuesday, telling reporters that he is a “fine person” and that the tapes were “conclusive”.
“If you look at that tape he was very very seriously maligned, and I think it’s very unfair,” he said.
