impeachment
Cases of Impeachment trial may not be held by jury.
The US Senate serves as the court, and the jury, for the trial that follows impeachment (accusal) by the House of Representatives.
The power to try for impeachment is solely the power of the United States Senate. The House of Representatives decides if there should be an impeachment, by a majority vote. After which, the investigation and trial is to be carried out by the Senate.
Except in impeachment cases, a trial by jury is a right guaranteed by the Constitution. It is not guaranteed in impeachment cases because life or liberty is not at stake.
The Senate
In cases of impeachment.
During an impeachment, the House of Representatives debates the case for impeachment and if there is enough evidence, passes a Bill of Impeachment. After the president is impeached, then a trial will be held in the Congress. The House presents the evidence supporting impeachment, and the Senate acts as a jury. If the Senate convicts, then the President would be removed from office. Two presidents have been impeached; Andrew Johnson and Bill Clinton. Neither were convicted by the Senate or removed from office.
The Senate is responsible for trying impeachment cases. The House of Representatives will bring the impeachment charge. A two-thirds majority vote is needed to impeach an official.
The full Senate serves as the jury in any impeachment trial. Most impeachment proceedings have been conducted against federal court judges (below the Supreme Court), so the Senate streamlined the trial process to allow the majority of Senators to conduct the chamber's regular business while an "Impeachment Trial Committee" listens to testimony and acts as a panel of judges. At the end of the trial, the committee compiles a report which the full Senate reads before voting for conviction or acquittal.
The Senate holds the (impeachment) removal trial after the House of Representatives has impeached the president. The Chief Justice of the United States (Supreme Court) only presides over the Senate impeachment trial of a US President; otherwise, the Presiding Officer of the Senate chooses a group of Senators to form an "Impeachment Trial Committee" to act as presiding judges. Certain members of the House of Representatives chosen by it act as prosecutors.
