With just three weeks left in the presidential election, Jimmy Kimmel has been railing against former President Donald Trump, who he claims has only grown “more erratic everyday.”

Kimmel roasted Trump on a recent episode of Jimmy Kimmel Live after Trump ranted against migrants at a rally. In a clip shared on Live, Trump is seen saying, “Kamala [Harris] has imported an army of illegal alien gang members and migrant criminals from the dungeons of the third world to prey upon innocent American citizens.”

After accusing immigrants of spreading “highly contagious diseases,” he says, “These people are the most violent people on earth and they’re bringing drugs, and they’re bringing crime, and they’re rapists.”

On his show, Kimmel fired back, “And that’s a man who knows rapists, I’ll tell you that. Better than anybody.” The Live crowd met his joke with raucous applause as he continued railing against the former president.

“Trump said, if elected, he will invoke the Alien Enemies act of 1978. If you’re not familiar with that, the last time it was used was to set up Japanese-American internment camps during World War II,” Kimmel pointed out. “This is not a healthy individual.”

Kimmel has been counting down the days till the election on Live by roasting Trump and those who have been backing him during this election cycle, including his running mate J.D. Vance and former candidate Robert F. Kennedy Jr.

During one episode, Kimmel staged a hilarious skit in which several audience members complained that they caught Vance having “his way” with their couches, inspired by the rumor that Vance wrote about having sex with a couch in his memoir Hillbilly Elegy.

One audience member dressed as an Ikea employee claimed Vance “mounted a Mörabo” and “was even seen fondling a Kïvïk,” both of which are sofas. “He’s one sick son of a b****,” he griped.

“Oh my god, this guy really has the hots for couch-type furniture,” Kimmel commented.

On other occasions, Kimmel has also called Trump out for ranting about the “dumbest nothing topics” and compared him to Sean “Diddy” Combs, who is currently being charged with sex trafficking.

“In some ways you kind of feel sympathy for J.D. Vance having to defend Donald Trump, who he himself openly denounced,” Kimmel said. “It’s kind of like being Diddy’s defense attorney.”
