John Kerry Brutally Trashes Trump with Bill Maher: '8-Year-Old Boy with the Insecurity of a Teenage Girl'

President Donald Trump came for former Secretary of State John Kerry hard on Thursday and the former secretary of state used his appearance on "Real Time with Bill Maher" Friday night to fire back even harder.

"Unfortunately, we have a president, literally, for whom the truth, the whole truth and nothing but the truth is three different things, and you don't even know what they are," Kerry said on the HBO late-night show. "He's got the maturity of an eight-year-old boy with the insecurity of a teenage girl. That's just who he is."

"He is the first president that I know of who spends more time reading his Twitter 'likes' than his briefing books or the constitution of the United States," he continued.

Earlier this week, Trump tweeted that Kerry's meetings with the "hostile" Iranian regime were "illegal," and that the Obama administration member was "BAD."

Kerry told Maher that it's not out of the ordinary for a former politician to meet with other officials.

"Well Henry Kissinger, for 40 years, has been traveling to Russia, traveling to China -- talks with the leaders. There's absolutely nothing unusual about it," he said.

Kerry fired back at POTUS on Twitter, too, saying he should be "more worried" about Paul Manafort meeting with Special Counsel Robert Mueller.

It was announced on Friday that Manafort -- Trump's former presidential campaign chairman -- struck a cooperative plea deal with prosecutors in exchange for some of the charges against him being dropped. He pleaded guilty in court Friday to one count of conspiracy against the US and one count of conspiracy to obstruct justice due to attempts to tamper with witnesses.

"Soon you'll be hearing [Trump] say, 'That's the worst deal that's ever been made,'" Kerry told Maher. "It's gone from the 'Art of the Deal' to the art of the squeal."

"I've never seen anything quite like it," Kerry said. "The anonymous op-ed, the Woodward book, the chronology of everything that's been happening. It's tough. We've always relied on our democracy, getting better, being stronger when people tell the truth."

Although Kerry, Maher, and the late-night host's roundtable continuously ripped Trump Friday night, Maher brought some in some optimism for his viewers and said that "Fat Donny" might be meeting his downfall.

"The polls for him are going down," Maher said. "The looks on the faces at the people at his rallies -- I think the magic is gone. They're bored. He hasn't written new material. They have a look like, 'Man, it's a lot about you.'"
