According to the U.S. Constitution, the House of Representatives holds the power to impeach, or charge with improper conduct, a President, Vice President, federal judge, or any other civil officer of the United States with “Treason, Bribery or other high Crimes and Misdemeanors.”
As the legal definition of “high Crimes and Misdemeanors” is not specified, it generally means a serious offense. Congress has broad discretion to determine which offenses are worthy or not worthy of impeachment.
