Speaker of the House John Boehner stunned audience members Wednesday evening at a Colorado fundraiser by referring to Republican presidential candidate Ted Cruz as a “jackass,” two people in attendance tell The Daily Caller.

At a Steamboat Springs event for GOP Rep. Scott Tipton, the Ohio Republican quipped that he likes how Cruz’s presidential campaign keeps “that jackass” out of Washington, and from telling Boehner how to do his job.

That remark rubbed some attendees the wrong way.

“I don’t think it’s terribly speaker-like, and I think it kind of goes against everything that Reagan ever said about disparaging Republicans,” said Ed MacArthur, the president of Native Excavating, who attended the fundraiser.

“It’s becoming very disturbing to me that we can’t have good, polite conversation,” MacArthur said. “It all has to be at the throat.”

But MacArthur added: “I do believe he’s got the right to say it.”
