A U.S. Congressman is a member of the United States Congress, which is the legislative branch of the federal government. Congress is divided into two chambers: the House of Representatives and the Senate. Congressmen serve in the House of Representatives, where they represent specific districts within their states. They are responsible for proposing and voting on laws, as well as addressing the needs and concerns of their constituents. Each Congressman serves a two-year term and can be re-elected multiple times. They participate in committees that focus on various issues, such as healthcare, education, and national security. By working together, Congressmen help shape the policies that affect the entire country.
