Fox News' Dana Perino, formerly a press secretary under George W. Bush, claimed Donald Trump is a 'liberal conspiracy theorist' pushing 'soft 9/11 trutherism' because he challenged Bush's handling of the attack.

"Well, I think it was a dismal weekend when you have liberal conspiracy theories being introduced by the Republican frontrunner," she said on Fox's The Five. "It is soft trutherism, it is what it is like soft racism and soft bigotry."

"You put it out there for a reason because you want to be provocative."
