‘History teaches that President Trump can be impeached even after leaving office,’ professor says

House Democrats have introduced one article of impeachment against President Trump, charging him with “incitement of insurrection” after last week’s attack at the Capitol. 

“It is past time for national leaders who wish to protect our nation and preserve its democracy to impeach and convict Donald Trump and/or seek to remove him from office via the 25th Amendment, both of which were intended to deal with precisely this sort of danger from executive power,” says Northwestern University history professor Michael Allen.

However, House Republicans today blocked a resolution calling on Vice President Mike Pence and cabinet members to invoke the 25th Amendment and remove President Trump from office.

Professors from the Northwestern Pritzker School of Law, as well as from Northwestern’s history department and the Medill School of Journalism, Media, Integrated Marketing Communications, are available for comment.

Quote from Professor Conway
“History teaches that President Trump can be impeached even after leaving office. In the 19th century, the Senate refused to dismiss an impeachment trial against the Secretary of War, even though the official had resigned. Conviction by the Senate in an impeachment trial would have real world consequences. If two-thirds of the senators vote to uphold the impeachment article, the Senate then could — by a simple majority vote — bar Trump from ever holding federal office again.”
