Days after Barack Obama sparred with Joe Biden in a war of words, the president challenged his former opponent to a bare-knuckle boxing match. “What I said about Joe is that in the middle of a bad basketball game, he’s got to start talking. I said it in public, and I was right,” Trump told The Daily Caller. “We could fight! It would be great for ratings. I’d be knocked out in a second. He’d be knocked out in a second. I think I’d win, and I’m a real fighter. But in a given time, if he asked me, if he is very courageous, I would fight him.”

Trump briefly challenged the president to a boxing match in June 2017, after the pair had an extended phone call in which the president said the two had sparred in the 1990s. At the time, Biden denied that the two ever fought in the ring. “We fought … in the boxing ring in Ireland or Scotland, whatever it was, and I knocked him the hell out,” Trump told the Daily Caller. “He was surprised at how fast I was, and I was surprised at how fast he was.” On Tuesday, Biden responded to Trump’s criticisms of him with a six-letter expletive, telling MSNBC, “You’re a jackass.”
