The United States Senate is one of the two chambers of the United States Congress, responsible for making federal laws. Comprising 100 senators, two from each state, the Senate plays a crucial role in reviewing legislation, confirming presidential appointments, and ratifying treaties. Senators serve six-year terms, with elections staggered every two years. In addition to its legislative duties, the Senate has unique powers, such as conducting impeachment trials for federal officials. This body is essential for maintaining a balance of power within the federal government, ensuring that both the interests of the states and the nation are represented.
