What Does the U.S. Vice President Do?

The vice president serves directly beneath the president and assumes the responsibilities of the presidency if the incumbent president dies or leaves office before the end of their term, as stated in the United States Constitution. The Twenty-Fifth Amendment further states that the vice president must serve as acting president in the event the incumbent president becomes temporarily incapacitated. The vice president also serves as president of the Senate, may preside over Senate sessions, and may cast tie-breaking votes when the elected senators reach a stalemate. In common practice, however, a vice president tends to spend little time in the Senate and primarily focuses on executive branch duties alongside the president and cabinet members. The Constitution provides almost no official duties for the vice president apart from assuming the presidency in the event of impeachment, resignation, or death in office. Most consistently, the vice president serves as key counsel for the president. The vice president attends cabinet meetings and leads them when the president is out of the country, and they play an active role in fundraising, presiding over public events, and representing the United States abroad, Decades of custom have added responsibilities to the role of vice president, particularly when it comes to foreign affairs. Congress formalized this aspect of the job in 1949 when it made the vice president a statutory member of the executive branch's National Security Council, giving the vice president an ongoing seat in conversations about foreign affairs. As the U.S. Constitution dictates, the president is at the top of the executive branch of government. The vice president is the president of the Senate, which falls under the legislative branch. As such, the vice president can serve as the presiding officer of the Senate at any time. When the vice president is not present, the Senate’s president pro tempore (the most senior member of the majority party) presides. In modern practice, the vice president typically spends little time presiding over the Senate unless a tied vote seems imminent. The Constitution confers minimal powers onto the vice president, so the vice president's power and scope of duties tend to emanate from the president. The role of vice president started out small and has gradually expanded under both Republican and Democrat presidents over the last century. - __1700s and 1800s__: The vice president's duties were few and far between. The first vice president, John Adams, called it "the most insignificant office," while President Abraham Lincoln's vice president, Hannibal Hamlin, was said to refer to himself as "the most unimportant man in Washington." - __1910s and ’20s__: President Woodrow Wilson leaned heavily on his vice president, Thomas R. Marshall. Marshall handled White House business while Wilson traveled to France to negotiate the end of World War I. - __1960s__: President John F.

Prior to this, vice presidents largely worked out of a building across the street from the White House. - __1990s and 2000s__: As vice president, Al Gore helped guide President Bill Clinton's environmental policy. President George W. Bush tasked Vice President Dick Cheney with broad military and foreign policy responsibilities. - __2020s__: In 2020 Kamala Harris became the first woman to assume the vice presidency.

Since the passage of the Twelfth Amendment in 1804, the president and vice president have run together on a single ticket for each presidential election. It has become traditional for one vice presidential debate to occur every four years so that voters can evaluate the nominees vying to be one step away from the presidency.
