Former President Donald Trump‘s impeachment trial will focus on whether he incited an insurrection, a charge that in a criminal court falls short of treason, the highest crime in the United States, and is easier to prove. Treason is an impeachable offense but not one that has been levied against Trump or any of the participants of the Capitol riot. The former president is charged with, and subsequently impeached over, committing “high crimes and misdemeanors” by using claims about the election’s integrity to encourage a mob of his supporters to breach Capitol security and engage in violence in an attempt to interfere with Congress‘ certification of President Joe Biden‘s Electoral College victory.
