A committee of representatives, called “managers,” acts as prosecutors before the Senate. The Senate sits as a High Court of Impeachment in which senators consider evidence, hear witnesses, and vote to acquit or convict the impeached official. In the case of presidential impeachment trials, the chief justice of the United States presides. The Constitution requires a two-thirds vote of the Senate to convict, and the penalty for an impeached official upon conviction is removal from office. In some cases, the Senate has also disqualified such officials from holding public offices in the future. There is no appeal. Since 1789, about half of Senate impeachment trials have resulted in conviction and removal from office.
