The President of the United States would be liable to be impeached, tried, and upon conviction of treason, bribery, or other high crimes and misdemeanors, removed from office; and would afterwards be liable to prosecution and punishment in the ordinary course of law. The person of the King of Great Britain is sacred and inviolable: There is no constitutional tribunal to which he is amenable, no punishment to which he can be subjected without involving the crisis of a national revolution.
