The Senate holds 'the sole Power to try all Impeachments': it sits as the court for every officer the House impeaches. Conviction requires two-thirds of senators present and carries removal from office, nothing less, nothing more without a further vote.
Read the clause itself, verbatim and in plain language, in the in-app Constitution.
The Senate, exclusively
Senators take a special oath and hear the House managers and the defense. The Chief Justice presides only when a President is tried (otherwise the VP or president pro tempore). Conviction removes the officer automatically; a separate majority vote can add disqualification from future federal office. Only eight officers, all judges, have ever been convicted and removed.
