Washington (CNN) Nearly 200 evangelical leaders are pushing back against an op-ed in a prominent Christian magazine that called for Donald Trump to be removed from office, saying the piece "offensively" dismissed their support of the President.

Following Trump's impeachment last week, Mark Galli, the outgoing editor of Christianity Today, called Trump a "grossly immoral character." The criticism was notable as evangelicals are a key constituency of Trump, who dismissed the magazine as "far left." The President will visit Miami early next month to attend the launch of the "Evangelicals for Trump" coalition, an event campaign officials said was set in motion before the editorial was published.

On Sunday, the evangelical leaders -- many of whom are public supporters of Trump -- affirmed their strong support of the President and slammed the magazine in a letter to Dr. Timothy Dalrymple, the president of Christianity Today, reported the Christian Post
