SHOW TRANSCRIPT

Former Speaker of the House John Boehner got really frank with his opinion of Ted Cruz during a discussion at Stanford University on Wednesday.

The Stanford Daily reports that Boehner described the presidential candidate as "Lucifer in the flesh."

And Boehner didn't stop there, saying, "I get along with almost everyone, but I have never worked with a more miserable son of a b---- in my life."

Boehner's issues with Cruz might stem, at least in part, from the government shutdown in 2013 when Boehner was still speaker. Cruz organized the shutdown in an attempt to block the Affordable Care Act, while Boehner was trying to keep the government open.

However, Boehner was a bit more friendly about Cruz's top rival, Donald Trump. Boehner said he has been golfing with Trump for years and that they are "texting buddies."

He also said he's "friends" with Ohio Gov. John Kasich but kept his comments pretty vague.
