The United States Senate is one of the two cameras of the Legislative branch, and is given exclusive powers established in the United States Constitution. Those exclusive powers are:
The power to confirm executive appointments: The President receives the advice and consent of the Senate in a vote process to appoint federal judges, executive positions and ambassadors.
The power to approve international treaties made by the President: Two-thirds of the Senate must vote in favor to approve international treaties, as part of the check and balances system, to restrain the power of the President.
The power to hold impeachment trials: The Senate holds impeachment trials when the House of Representatives decides to impeach an elected official, two-thirds votes are required to remove the officer.
