The functions of the Senate (of the U.S.A.) fall into three classes: legislative, executive, and judicial. Its legislative function is to pass, along with the House of Representatives, bills which become Acts of Congress on the assent of the President, or even without his consent, if passed a second time by a two-thirds majority of each House, after he has returned them for reconsideration. Its executive function are (a) to approve or disapprove the President’s nominations of Federal officers, including judges, ministers of state, and ambassadors; (b) to approve, by a majority of two-thirds of those present, of treaties made by the President-i. e., if less than two-thirds approve, the treaty falls to the ground. Its judicial function is to sit as a court for the trial of impeachments preferred by the House of Representatives.
