All U.S. senators and representatives collectively make up the United States Congress, which is the legislative branch of the federal government. Congress is divided into two chambers: the Senate, composed of 100 senators (two from each state), and the House of Representatives, which has 435 members apportioned based on state populations. Together, they are responsible for making Federal Laws, overseeing the executive branch, and representing the interests of their constituents.
