President Donald Trump slapped back at former Vice President Joe Biden, who said this week that the current president deserved a beating over his treatment of women.

Biden said Tuesday during an anti-sexual assault rally at the University of Miami that he would have "beat the hell out of" of Trump if they'd attended high school together, and the president tweeted out a response early Thursday morning.

"Crazy Joe Biden is trying to act like a tough guy" Trump tweeted. "Actually, he is weak, both mentally and physically, and yet he threatens me, for the second time, with physical assault. He doesn’t know me, but he would go down fast and hard, crying all the way. Don’t threaten people Joe!"

Biden said he would not have argued with Trump over his "Access Hollywood" comments about grabbing women by the genitals if the two had been high school classmates, but instead would have responded physically.

"They asked me would I like to debate this gentleman, and I said no. I said, 'If we were in high school, I'd take him behind the gym and beat the hell out of him,'"Biden said.

Trump apologized for the remarks, which were recorded in 2006 but revealed weeks ahead of the 2016 presidential election, and said they were just "locker room talk."

"I've been in a lot of locker rooms my whole life, I'm a pretty damn good athlete," Biden said. "Any guy that talked that way was usually the fattest, ugliest S.O.B. in the room."
