The U.S. Constitution set in place a process for removing from office elected and non-elective executive and judicial officers of the United States: that process is commonly called impeachment. It is a power of the national legislature, the Congress; and both the House of Representatives and the Senate play roles, separately but in coordination. On occasion the Chief Justice of the United States also plays a role. Understanding the impeachment power and how the process operates has recently become much discussed. So a discussion of the bases and principles of impeachment appears particularly appropriate.
