Arnold maintains that recordings exist of Trump using racial slurs and exhibiting misogynist behavior while shooting "Apprentice".
Patton Oswalt tweeted: 'I'm with Tom Arnold, everyone. (A source within earshot of the tussle said Arnold challenged Burnett on the Apprentice outtakes, specifically.) The source also said it was unclear who made the first move. Before this brawl, Arnold told Salon that he planned to confront Burnett, saying, "I'm definitely going to do something at the Emmys".
Downey claims Arnold "ambushed" her and her husband, producer Mark Burnett, at a charity event.
Arnold has claimed that Trump has used the N-word and is "obviously a racist", adding that the president's take on the National Football League is because "he doesn't like black guys".
"They're really anxious about me being anywhere near him", Arnold told Salon about Burnett. "He sits next to Donald Trump and gives him cover and he never says one word". He confirmed the altercation (he calls it an "unprovoked attack" by Burnett) and says Tom "has a witness" that will back him up. Mark Burnett says he's a Christian?
