More than 20 faculty members, graduate students and administrators who identify as political scientists signed an open letter calling for President Donald Trump to be removed from office through the impeachment process or through the 25th amendment.

The letter comes after pro-Trump rioters stormed the U.S. Capitol Wednesday, the same day members of Congress were working to finalize President-elect Joe Biden’s win in the 2020 presidential election. The letter states that Trump’s actions to reject a peaceful transfer of power, his efforts to pressure election officials to overturn state election results and his role in inciting the Capitol riots “threaten American democracy.”

Signers include members of the American studies and political science departments in the Columbian College of Arts and Sciences, Elliott School of International Affairs, School of Media and Public Affairs, Graduate School of Political Management and GW Law.

“Our profession seeks to understand politics, not engage in it, but we share a commitment to democratic values,” the letter states. “The President’s actions show he is unwilling or unable to fulfill his oath to protect and defend the Constitution. He should be removed from office immediately before further violence takes place or further damage is done to our democracy.”
