Christianity Today, a prominent evangelical magazine, called for President Trump to be removed from office in a blistering editorial on Thursday, a day after he became the third president in history to be impeached and face expulsion by the Senate.

The move was the most notable example of dissent among the religious conservative base that has supported Mr. Trump through controversy after controversy, and came at one of the most vulnerable moments of his presidency.

“The president of the United States attempted to use his political power to coerce a foreign leader to harass and discredit one of the president’s political opponents,” Mark Galli, the editor in chief of Christianity Today, wrote in the editorial. “That is not only a violation of the Constitution; more importantly, it is profoundly immoral.”
