Religious scholar Reza Aslan, host of CNN’s Believer, went on a profane Twitter rant against President Donald Trump on Saturday night, calling Trump a “piece of shit”, a “stain on the presidency” and an “embarrassment to America…and humanity” over Trump’s calling for reinstatement of his travel ban in response to the London terror attacks earlier Saturday night.

Aslan is an Iranian Shia Muslim refugee who came to America with his family during the Islamic revolution that overthrew the Shah in 1979, according to Wikipedia. Aslan says he became an American citizen.

“This piece of shit is not just an embarrassment to America and a stain on the presidency. He’s an embarrassment to humankind.”

The tweet by Trump that Aslan blew up at read, “We need to be smart, vigilant and tough. We need the courts to give us back our rights. We need the Travel Ban as an extra level of safety!”

CNN describes Believer as “In this new spiritual adventure series, renowned author and religious scholar Reza Aslan immerses himself in the world’s most fascinating faith-based groups to experience life as a true believer.” Aslan’s Believer is a six-part series that debuted on March 5.

Aslan also on Saturday posted what appears to be a veiled death wish for Republican Congressman Tim Walberg of Michigan for saying last week that God will take care of climate change.

Aslan wrote, “Any chance God could take care of Tim Walberg first?”

Walberg’s comments as reported by USA Today.

“I believe there’s climate change,” Walberg said, according to a video of the exchange obtained first published by the Huffington Post. “I believe there’s been climate change since the beginning of time. I think there are cycles. Do I think man has some impact? Yeah, of course. Can man change the entire universe? No.” “Why do I believe that?” he continued. “Well, as a Christian, I believe that there is a creator in God who is much bigger than us. And I’m confident that, if there’s a real problem, he can take care of it.”
