Attorney Michael Avenatti speaks during a news conference with Battle Born Progress, a progressive communications organization, on August 31, 2018 in Las Vegas, Nevada. Avenatti is representing adult film actress/director Stormy Daniels in her cases again

Politically ambitious anti-Trump attorney Michael Avenatti challenged Donald Trump Jr. to a mixed-martial arts fight on Tuesday, because, of course he did.

“I’m having lunch with Michael Avenatti at the Vanity Fair Summit and he’s proposing a three-round mixed-martial arts fight with Donald Trump Jr. for charity. No joke,” tweeted reporter Dylan Byers.

“This would be for two great causes. I’m in,” Avenatti tweeted, confirming the MMA fight challenge.

Thus far, Avenatti, who’s representing porn star Stormy Daniels, and Trump have only traded jabs on Twitter.

Trump captioned a tweet on Monday regarding the prison release of disgraced former Congressmen Anthony Weiner. “Who else is excited about Avanetti/Weiner 2020?!? It’s gonna be Carlos Dangerous,” he wrote, making reference to Weiner’s sexting alias “Carlos Danger.”
