"How can he keep saying something without providing any proof? And there wasn't any," John Boehner said about Trump's baseless claims after the election.

Boehner skewered Cruz in a released excerpt of his memoir, calling him a "reckless a--hole who thinks he is smarter than everyone else."

Boehner noted that the former president misled voters by spreading lies about the election even before it happened.

"The president abused the loyalty and the trust that voters placed in him by perpetuating this noise," Boehner said of Trump's false election claims.

John Boehner and Ted Cruz have traded barbs over the last week as Boehner takes aim at his former Republican colleagues in a forthcoming book.

"He stepped all over their loyalty to him by continuing to say things that just weren't true," Boehner told USA Today about Trump and his followers.

For Boehner, a jovial, backslapping politician who is known to publicly cry, McConnell's steely and to-the-point demeanor is quite a contrast.

"The deal is this - Boehner and I got a lot done, but we didn't mince words," he said. "He was right. I did everything I could to cause him trouble."

Boehner criticized current GOP leaders like Donald Trump and Ted Cruz, who he called a "reckless a--hole who thinks he is smarter than everyone else."

"I just never saw a guy who spent more time tearing things apart ― never building anything, never putting anything together," Boehner said of Rep. Jordan.

In an interview that will air on "CBS Sunday Morning" this weekend, Boehner, who's promoting his new memoir, described Cruz as an attention seeker.

"I don't even think I could get elected in today's Republican Party anyway," Boehner writes in his new book, per an excerpt from the Washington Post.

Boehner wrote that Clinton's impeachment was a political effort by his party to win House seats in the midterms.

"Poor McConnell ... Mr. Decorum was a stunned and horrified witness to this angry encounter," Boehner wrote.

Trump once flew into a rage at one of Boehner's staffers with "real anger," showing an explosive temper long before he became president, Boehner said.

Responding to Boehner's criticism, Trump said, "Was he drinking when he made this statement? Just another RINO who couldn't do the job!"

The former House speaker was apparently drinking wine while recording, sources told Axios, and went off on Cruz while talking about freedom.
