Ted Cruz Mocked by John Boehner as 'Lucifer in the Flesh'

John Boehner has rejected Ted Cruz's effort to unite the GOP.

In a talk at Stanford University Wednesday, the plainspoken Ohio Republican called the Texas senator "Lucifer in the flesh," adding that he found Cruz difficult to work with in Congress.

“I have Democrat friends and Republican friends," Boehner said, according to the Stanford Daily. "I get along with almost everyone, but I have never worked with a more miserable son of a b---- in my life.”

Boehner, an avid golfer, said he and 2016 front-runner Trump are "texting buddies," and that they've played golf together over the years. He stopped short of endorsing his policies, but said he would vote for Trump in the general election if the New York businessman becomes the GOP nominee.

Cruz took to Twitter this morning, writing, "Tell me again who will stand up to Washington? Trump, who's Boehner's "texting and golfing buddy," or Carly & me?"

In Indiana today, Cruz dismissed Boehner's comments, and said he didn't know him well.

"I've met John Boehner two or three times in my life. If I have said 50 words in my life to John Boehner. I would be surprised and every one of them has consisted of pleasantries," Cruz said.

Cruz's campaign spokesperson, Catherine Frazier, said the two did not directly work together when Boehner employed Cruz to represent him in a lawsuit in the late 1990's against Rep. Jim McDermott, D-Washington, when the Washington Democrat leaked an illegally recorded phone call to the New York Times.
