John Boehner slams Ted Cruz: 'I have never worked with a more miserable son of a bitch in my life'

John Boehner harshly denounced Sen. Ted Cruz as "Lucifer in the flesh" during a discussion Wednesday night at Stanford University.

The former Speaker of the House discussed the future of the Republican Party during the discussion -- but he saved his strongest criticism for the Texas senator and GOP presidential candidate, reported the Stanford Daily.

“I have Democrat friends and Republican friends," Boehner said. "I get along with almost everyone, but I have never worked with a more miserable son of a bitch in my life.”

Boehner said he and Donald Trump had played golf together and were "texting buddies," but he was a bit ambiguous about his relationship with Ohio Gov. John Kasich.

"He requires more effort on my behalf than all my other friends," Boehner said. "But he’s still my friend, and I love him."
