President Donald Trump is responding to Joe Biden’s attacks against him in an early morning tweet, all but saying he could take Biden on, and I don’t mean in a political campaign.

Crazy Joe Biden is trying to act like a tough guy. 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!

The feud began when Biden said at a sexual assault rally that he would have “beat the hell” out of Trump in high school.” Via the Washington Times:

“A guy who ended up becoming our national leader said, ‘I can grab a woman anywhere and she likes it,’” Mr. Bidentold the crowd. “They asked me if I’d 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.’

“I’ve been in a lot of locker rooms my whole life,” he continued. “I’m a pretty damn good athlete. Any guy that talked that way was usually the fattest, ugliest S.O.B. in the room.”

The former vice president made the comments at UM’s “It’s on Us” rally, an event aimed at changing campus culture surrounding sexual assault, ABC News reported. He ended his speech by encouraging students to participate in Sexual Assault Awareness Month next month and the Day of Action April 3.

Trump, in typical form, chose to respond on social media with his usual tact and grace.

Biden started the fight, so in this case, Trump isn’t responding to nothing. Biden chose to draw first blood and has set himself up for no less than five tweets on Donald Trump’s Twitter timeline. And, while we would prefer that Trump take some time off Twitter to focus on presidenting, in this case, I can’t blame him.
