The primary function of the Senate in the U.S. government is to represent the interests of states in the federal legislative process. Comprising 100 senators, each state is represented equally, giving smaller states a significant voice compared to the House of Representatives. The Senate has key responsibilities, including ratifying treaties, confirming presidential appointments, and conducting impeachment trials. This upper chamber serves as a check on the House and ensures that legislation is thoroughly debated and considered. Consequently, the Senate plays a critical role in fostering bipartisan collaboration and maintaining a balance of power within the federal government.
