Final answer:
The Senate holds the trial of an impeached official, with the House of Representatives bringing charges of impeachment. The Chief Justice of the Supreme Court presides over the impeachment trial of a president.
Step-by-step explanation:
The Senate holds the trial of an official who is impeached.
According to the U.S. Constitution, the House of Representatives has the power to impeach an elected official, while the Senate serves as the judge and jury in the trial. The Chief Justice of the Supreme Court presides over the impeachment trial of a president. If two-thirds of the Senators vote for conviction, the impeached official is removed from office.
Based on historical examples, it's worth noting that an impeachment trial has been held twice in the past - in the cases of Andrew Johnson in 1868 and Bill Clinton in 1998 - but in both instances, the Senate did not convict.
