"The View's" Meghan McCain took issue with some of her fellow hosts on Friday after they agreed with a conservative guest who called Trump supporters "a cult."


At the start of the segment, co-host Joy Behar played a clip of Trump denying that he had ever criticized U.K. Prime Minister Theresa May in an interview with a British tabloid -- despite the fact that the newspaper had recorded the entire interview and released audio of it on the web.

"He's calling his own words fake news!" Behar cracked.

Conservative commentator Tara Setmayer, who was a guest on Friday's show, said she was aghast that Trump can get away with lying in such obvious ways without his fans ever questioning their faith in him.

"It's a cult!" she exclaimed.

"Please stop saying that!" an upset McCain interjected. "You said that the last time you were here, it's so redundant!"

Setmayer, however, would not back down.

"There's a large group of people who blindly follow what this man says, that don't think for themselves," she said. "He can get away with saying things on tape and then calling it fake news! That is a cult!"

McCain said that calling Trump's fans a "cult" was not helpful to understanding them.

"I defend his supporters because I understand it," she said. "You're painting everyone with a giant swathe that everybody's been brainwashed, that we're all in a cult."

Setmayer didn't budge an inch.

"There's a large group, including a lot of members of Congress, who have completely sold their principles down the river," she said.
