“He’s also too old,” Rudy Giuliani said of former Vice President Joe Biden. “He’s four years older than Trump.” Trump is 72 and Biden is 75; Giuliani is 74. | Alex Wong/Getty Images Giuliani calls Biden a 'mentally deficient idiot' 'He’s also too old,' the president's attorney added.

Rudy Giuliani, the president’s personal attorney, isn’t just taking the fight to special counsel Robert Mueller — he’s also dressing down Democrats considering taking on Donald Trump in 2020, including Joe Biden.

The former New York mayor called the ex-vice president “a moron” in an interview with HuffPost on Friday, and the name-calling didn’t stop there.


“I’m calling Joe Biden a mentally deficient idiot,” Giuliani said, claiming Biden finished last in his class at New York’s Syracuse University College of Law.

“He’s also too old. He’s four years older than Trump,” Giuliani added. Trump celebrated his 72nd birthday on Thursday. Biden is 75.

Though Giuliani said Trump would easily capture another term in the White House, regardless of his general election opponent, he said older, better-known contenders like Biden or Sen. Elizabeth Warren (D-Mass.) would pose less of a challenge to the incumbent president than “unknown” faces within the Democratic Party.

“They need someone new, who would be more threatening to us,” Giuliani said. “They’ve got to hit us with a surprise.”

Biden has been a vocal critic of the president since the 2016 campaign, and their verbal fisticuffs veered toward a physical brawl after the Delawarean claimed in March that he would have thrashed the Manhattanite for his history of lewd comments, had they been in high school.

"A guy who ended up becoming our national leader said, 'I can grab a woman anywhere and she likes it,'" Biden said at University of Miami event on combating campus sexual assault. "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.'"

Biden was referring to Trump’s infamous remarks from the 2005 “Access Hollywood” tape in which the president bragged about sexually assaulting women.

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

Trump fired back with his own smack talk via Twitter later that week.

“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 wrote online. “He doesn’t know me, but he would go down fast and hard, crying all the way. Don’t threaten people Joe!”

Biden said a few days after the spat that he regretted his remarks.

“I shouldn’t have said what I said. I shouldn’t have brought it up again, because I don’t want to get down in the mosh pit with this guy,” he told the hosts of the “Pod Save America” podcast. “The idea that I would actually physically get in a contest with a president of the United States or anybody else now is not what I said, and it is not what this was about, but I should have just left it alone.”
