The three powers of the Senate that are assigned exclusively to it are:
-
Try cases of the impeachment of federal officials - The Senate holds the trial for impeached officials and decides whether to convict or acquit.
-
Ratify treaties - The Senate has the power to ratify treaties made by the President, requiring a two-thirds majority for approval.
-
Confirm Presidential appointments - The Senate has the authority to confirm appointments made by the President for federal positions, including Supreme Court Justices and Cabinet members.
The other options are not exclusive to the Senate, as the House of Representatives initiates revenue bills and has the sole power to impeach federal officials. The Senate does not elect the President in the event of an Electoral College tie; that responsibility falls to the House of Representatives.
