'It's not a joke': CNN pundits crack up while reading new detail in Trump tell-all

CNN pundits couldn't hold it together as they heard about a new detail in an upcoming tell-all about the Trump White House.

The upcoming book Regime Change, written by New York Times reporters Maggie Haberman and Jonathan Swan, detailed how Trump showed them a document that argued he was more powerful than historical strongmen like Attila the Hun, Genghis Khan, Napoleon, Stalin, Mao, and Hitler.

After a little digging, it turned out that the document wasn't written by a presidential historian like Trump claimed, but by Hall of Fame golfer Gary Player's long-time caddy, according to reports.

CNN anchor Abby Phillip explained as much to her pundits on Thursday, but she cracked up and couldn't get through the whole recap.

"It's not a joke," Phillip said as she laughed. "This actually happened."

Political commentator Xochitl Hinojosa and Democratic former congressional candidate Isaiah Martin couldn't contain themselves either and laughed out loud alongside Phillip.

"This is the president of the United States," Hinojosa said, covering her face.

Hinojosa admitted, "It is scary that he is comparing himself [to those figures]. He has unlimited power. He is essentially saying that he is a lot like a dictator." She did find consolation in describing Trump as a historically unpopular president, though.

"He can try to say in his head that he is the most powerful, that he is like a dictator, that he has all the power in the world," Hinojosa said. "But the reality is that this man is going to go down as probably one of the least popular presidents."
