WATCH: 'Christo-fascist' Mike Flynn makes 'terrifying' and 'dangerous' call for ‘one religion’ in the U.S.

Mike Flynn, former president Donald Trump's one-time national security adviser, called for "one religion" in the U.S. on Saturday.

"If we are going to have one nation under God, which we must, we have to have one religion," Flynn said at a ReAwaken America event in San Antonio. "One nation under God, and one religion under God."

After attorney Ron Filipowski posted video of Flynn's comments, Twitter erupted.

Ben White, Politico's chief economic correspondent, called Flynn's comments "as fundamental a rejection of the very founding principles of this nation as you are likely to find."

CNN senior broadcast producer Javier de Diego agreed. "Literally the opposite of what the Constitution says," he wrote.

Former U.S. Attorney Preet Bharara said, "Wow look how much Michael Flynn hates America."

"And is that religion QAnon?" MSNBC analyst David Corn wrote.

New Yorker magazine writer Jonathan Chait said: "Is it going to be Judaism? …It's not going to be Judaism, is it?"
