Seth Meyers compared Donald Trump to a teenage boy during Monday’s episode of Late Night With Seth Meyers, blasting both the president-elect and his aides for peddling false conspiracy theories.

“When you’re dealing with foreign powers in unstable regions, you need sober, analytical thinking and a firm grasp of reality, qualities you definitely do not associate with Donald Trump. The only qualities less associated with Donald Trump are modesty and a dancer’s body,” Meyers joked during Monday’s edition of A Closer Look.

Meyers then highlighted Trump’s Nov. 27 tweet, in which the former reality television host falsely claimed he “won the popular vote if you deduct the millions of people who voted illegally.” (Hillary Clinton leads Trump by more than 2 million votes in the popular vote.)

“Kind of like how the Cleveland Indians won the World Series if you don’t count the last two games,” Meyers joked. He added, “There is no evidence for this claim. One report found that out of 135 million ballots cast, there had been just four documented cases of voter fraud in the 2016 election. There were fewer cases of voter fraud than there are acceptable spellings of Hannukah.”

Following the tweet, Trump attacked the media — even retweeting a 16-year-old boy who had blasted CNN on the social media platform. Meyers noted that “it makes sense that Trump would identify with a 16-year-old, as he has surrounded himself with a team of aides and spokespeople who defend his actions the way entitled parents would defend the sh–y kid at a high school.”

The host then played clips from recent television interviews with Vice President-elect Mike Pence (“He’s entitled to express his opinion on that”) and incoming chief of staff Reince Priebus, who said he “didn’t know” if Trump’s false statement was inaccurate. “It’s possible,” Priebus said.

That remark drew Meyers’ ire: “Stop saying everything is possible. You’re chief of staff, you’re not Kevin Garnett.”
