President Donald Trump and Tucker Carlson are engaged in a bitter war of words after the conservative pundit condemned the president’s “vile” Easter Sunday message that he said made a “mockery of Christianity.”

In an episode of “The Tucker Carlson Show” released Monday, the former Fox News host denounced Trump’s profanity-laden Truth Social post that ramped up threats to destroy Iran’s civilian infrastructure if the regime refuses to reopen the Strait of Hormuz, the shipping route for up to one-fifth of the world’s oil supply.

“Tuesday will be Power Plant Day, and Bridge Day, all wrapped up in one, in Iran,” Trump wrote. “Open the Fuckin’ Strait, you crazy bastards, or you’ll be living in Hell - JUST WATCH! Praise be to Allah. President DONALD J. TRUMP.”

Carlson, a former Trump loyalist, condemned the president’s Sunday message as “vile on every level.” He said that military action that deliberately harms noncombatants is “evil” and urged administration officials to defy Trump’s orders.

“If you work in the White House or in the U.S. military, now it’s time to say ‘no, absolutely not,’ and say it directly to the president,” he said.

Trump fired back on Tuesday, calling Carlson “a low IQ person that has absolutely no idea what’s going on,” according to the New York Post’s Caitlin Doornbos.

He has since intensified his saber-rattling against Iran, threatening on Tuesday that “a whole civilization will die tonight” if the country ignores his deadline to reopen the Strait of Hormuz.

Carlson’s monologue on Monday, which began with the pundit denouncing Trump’s invasion of Venezuela, called the president’s threat to destroy Iran’s civilian infrastructure “a war crime, a moral crime, against the people of the country,” and predicted what would happen if the country lost power.

“People die. Babies connected to incubators die,” he said, warning that starvation and a refugee crisis would follow, leading to “mass suffering and death.”

“That is immoral, that will never be moral, that can never be justified, that is always wrong,” Carlson said.

Carlson’s most explosive reaction came as he read out the section of Trump’s post that included the curse, noting that the president posted it on “the holiest day in Christian life.”

“How dare you speak that way on Easter morning to the country?” Carlson admonished. “Who do you think you are? You’re tweeting out the f-word on Easter morning.”

Regarding Trump’s “Praise be to Allah” message, Carlson said, “No decent person mocks other people’s religions.”

“It’s a mockery of Christianity to send out a tweet with the f-word on Easter morning, promising the murder of civilians and then saying ‘Praise be to Allah’ without explaining any of it. You are mocking me and every other Christian,” he added.
