The United States Senate, one of the two chambers of Congress, is composed of two senators from each of the 50 states who serve six-year terms without term limits. Its key functions include drafting and passing legislation, confirming presidential appointments, and ratifying treaties. The Senate’s structure ensures equal representation for all states, regardless of population, balancing the House of Representatives’ population-based approach. Its comparatively longer terms are intended to promote stability of national policies.
Senators are elected by popular vote in their respective states, with elections held every two years for approximately one-third of the seats. Leadership roles of the Senate include the Vice President, who serves as presiding officer and can break ties; the President Pro Tempore, elected by the majority party to preside in the Vice President’s absence; and Majority and Minority Leaders, elected by their respective parties to set agendas and manage legislative strategy. Additionally, each party elects Whips to ensure party discipline on votes. The Senate operates through specialized committees that review legislation, conduct investigations, and provide oversight of government agencies.
