Burnett's wife, actress Roma Downey, tweeted a photo of what she said was her bruised hand as a result of the alleged altercation.
Arnold's new show, The Hunt for the Trump Tapes, is set to debut Tuesday. "I'm waiting for LAPD", claimed Arnold via Twitter, adding that he's going to sue Downey for defamation.
Arnold is the host of Viceland's series The Hunt for the Trump Tapes, where he will ostensibly search for damning footage from President Trump's past.
The actor said the TV producer attacked him and ran away and that he has called police to file a report.
The lawyer, Martin Singer, said Burnett "attacked" Arnold.
Later that night, Arnold was overheard telling people that the Trump tapes he found have been "handed over to Ronan Farrow". Before this brawl, Arnold told Salon that he planned to confront Burnett, saying, "I'm definitely going to do something at the Emmys". Arnold reportedly pushed Burnett who pushed him back and that's when Arnold ripped Burnett's crucifix necklace off of his neck. Whether that was enough to cause Burnett to start this physical altercation with Arnold, is yet to be seen. The president also reportedly uses the N-word and "calls Eric [Trump] the R-word", Arnold told Jimmy Kimmel.
The actor has been demanding for months that the tapes be released by Apprentice producer Mark Burnett.
Tweeting about the tapes last week, he said: "I've known Donald Trump for 30 years & he's always been a lying cheating racist sexual assaulting incompetent surrounded by sycophants".
Hill Reporter reached out to Mr. Arnold regarding Downey's post.
And, for his part, Donald Trump tweeted that he doesn't "have that word in my vocabulary, and never have". "She made it up". Reps for Burnett and Downey declined to comment.
