Can the Senate try President Donald Trump after he leaves office? The answer to that question lies with, you guessed it, the Senate. In reaching a decision, the Senators may choose to be guided by a precedent: that of William W. Belknap, Ulysses S. Grant’s Secretary of War.

Belknap resigned mere hours before the House of Representatives impeached him. The Senate tried him anyway — although a substantial number of senators insisted throughout that they had no authority over a government official who had already resigned. As a consequence the Senate did not convict Belknap by the constitutional two thirds requirement.
