Only three presidents have been impeached in U.S. history. Former President Donald Trump is the only one to be impeached a second time—which means he accounts for 50 percent of all presidential impeachments. Trump’s Senate trial begins Tuesday, triggering another historic first: He’s the only former president to be tried by Congress. Pursuing charges against a president no longer in office “could open the door to increased impeachments by both parties,” warns Dan Urman, who teaches a course at Northeastern on Constitutional law and the modern U.S. Supreme Court.
