Who has the power to impeach and remove from office a federal judge or other official who commits a crime?

The power to impeach a federal judge or other official lies with the House of Representatives, which can initiate impeachment proceedings. If the House votes to impeach, the case is then sent to the Senate, which conducts a trial. A two-thirds majority in the Senate is required to convict and remove the official from office. This process is outlined in the U.S. Constitution.
