Sen. Ted Cruz hit back this morning after he was slammed by former House Speaker John Boehner. 

"Lucifer in the flesh," the Ohio lawmaker called Cruz during an appearance at Stanford University.

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

Cruz, campaigning with his VP choice Carly Fiorina in Indiana, responded by saying he doesn't know Boehner and has barely talked to him during his time in the Senate. 

"I've never worked with John Boehner. The truth of the matter is I don't know the man. I've met John Boehner two or three times in my life," said Cruz, adding that he's never had a "substantive" conversation with him. 

Cruz said during the government shutdown, he and Sen. Mike Lee reached out to the then-Speaker, trying to work with him on "getting something meaningful done" to stop ObamaCare.

"His response was 'I have no interest in talking to you,'" Cruz recalled.

He argued that Boehner is "angry" that Cruz is standing up for conservative principles in Washington and trying to hold him accountable.
