Under Article II, Sec. 4 of the US Constitution, Congress has
the power to impeach the President, the Vice President and
"all civil Officers of the United States" for
"Treason, Bribery, or other high Crimes and
Misdemeanors." If the House approves one or more articles of
impeachment by a simple majority vote, the Senate conducts a trial
that will result in a removal from office only if two-thirds of the
Senate votes to convict.
This publication examines (I) the process of impeachment, (II)
the two prior instances in which a US President has been impeached,
but not convicted (as well as the instances in which judges have
been impeached) and (III) the impeachment efforts targeting US
President Donald Trump.
