Vice President of the United States Formerly, the vice president would preside regularly over Senate proceedings, but in modern times, the vice president rarely presides over day-to-day matters in the Senate; in their place, the Senate chooses a President pro tempore (or "president for a time") to preside in the vice president's absence; the Senate normally selects the longest-serving senator in the majority party. The President pro tempore has the power to appoint any other senator to preside, and in practice junior senators from the majority party are assigned the task of presiding over the Senate at most times.
Vice President of the United States The Constitution limits the formal powers and role of vice president to becoming president,[14][15] should the president become unable to serve, prompting the well-known expression "only a heartbeat away from the presidency," and to acting as the presiding officer of the U.S. Senate. Other statutorily granted roles include membership of both the National Security Council and the Board of Regents of the Smithsonian Institution.[16][17]
