A member of Congress is an elected official who serves in the legislative branch of the United States government. Congress is divided into two chambers: the House of Representatives and the Senate. Members of the House serve two-year terms, while Senators serve six-year terms. Their primary responsibility is to create, debate, and vote on laws that affect the country. Members of Congress represent the interests of their constituents, the people who live in their electoral districts or states. They also participate in committees that focus on specific issues, such as healthcare, education, or national security, helping to shape policies and oversee government functions.
