In which type of trial do Senate members act as jurors for the House?

Senate members serve as jurors in impeachment trials, which is a unique function outlined in the U.S. Constitution. When a federal official, including the President, is impeached by the House of Representatives, it is the Senate's responsibility to conduct the trial. During this process, Senators evaluate the evidence presented and ultimately vote on whether to convict or acquit the official. The requirement for a two-thirds majority to convict demonstrates the seriousness of the process, reflecting the high stakes involved in impeaching a federal official.

Civil and criminal trials, on the other hand, are handled in the judicial system, with judges and juries made up of citizens, not members of Congress. Appeals trials also fall outside the purview of the Senate’s responsibilities. Thus, it is specifically within the context of impeachment that Senators take on the role of jurors.
