Final answer:
The House of Representatives brings the impeachment charges, while the Senate conducts the trial and decides on the president's guilt or innocence, with a two-thirds vote needed to convict and remove the president from office.
Step-by-step explanation:
The House of Representatives is the body of Congress that brings impeachment charges against a president. The Senate is the body of Congress that decides if the president is innocent or guilty. Impeachment proceedings begin in the House, which has the sole power to impeach, or formally accuse, the president of high crimes and misdemeanors. If the House votes by a simple majority to impeach the president, the process moves to the Senate, where a trial is held.
In this trial, the members of the House act as prosecutors, the Senate serves as the jury, and the chief justice of the Supreme Court presides over the proceedings. A two-thirds vote in the Senate is necessary for conviction. If the president is convicted, the punishment includes removal and disqualification from office.
