Answer:
The U.S. Constitution defines several powers exclusive to the U.S. Congress, among them:
- The power to formally declare war, vested on the Senate.
- The power to raise revenue (collect taxes). Bills that raise revenue have to originate in the House.
- The power to impeach the President. One of its most famous discretionary powers. The House accuses, and the Senate decides the trial.
- The power to confirm Justices of the Supreme Court - also a discretionary power given specifically to the Senate: the president presents a candidate, and the Senate either confirms or rejects the candidate.
