Final answer:
A president, vice president, or other officers of the federal government can be impeached and removed from office for treason, bribery, or other high crimes and misdemeanors. Three U.S. presidents have faced impeachment proceedings: Andrew Johnson, Richard Nixon, and Bill Clinton.
Step-by-step explanation:
According to Articles I and II of the Constitution, a president, vice president, or other officers of the federal government can be impeached and removed from office for treason, bribery, or other high crimes and misdemeanors. Impeachment is the act of charging a government official with serious wrongdoing, and it is initiated in the House of Representatives. Removal from office happens after a trial in the Senate, where a two-thirds majority vote is required for conviction.
Three U.S. presidents have faced impeachment proceedings. Andrew Johnson was impeached while in office but narrowly avoided removal from office. Richard Nixon resigned from office before an impeachment trial could take place. Bill Clinton was impeached by the House of Representatives but was found not guilty by the Senate.
