U.S. President Donald Trump on Friday blasted the magazine founded by the late Reverend Billy Graham after the influential publication for conservative evangelical U.S. Christians called for him to be removed from office.

Christianity Today on Thursday wrote in an editorial entitled “Trump Should Be Removed from Office” that it could no longer stand on the sidelines after the Republican president’s impeachment this week by the U.S. House of Representatives.

“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,” it wrote. “That is not only a violation of the Constitution; more importantly, it is profoundly immoral.”

The Democratic-led House impeached Trump on charges of abuse of power and obstruction of Congress over his effort to pressure Ukraine to investigate former Vice President Joe Biden, a leading candidate for the Democratic nomination to face Trump in the 2020 election. The Republican-led Senate is expected to hold a trial next month on whether to remove Trump from office.

Trump, who has denied wrongdoing and branded his impeachment as a politically-motivated effort by Democrats to overturn the results of the 2016 election, questioned Christianity Today’s success and dismissed its call that he be removed from office.
