The U.S. Congress is the legislative branch of the federal government of the United States, responsible for making laws. It is a bicameral body, consisting of two chambers: the House of Representatives and the Senate. Members of Congress are elected to represent the interests of their constituents and play a crucial role in shaping national policy. Congress has the power to draft and pass legislation, declare war, regulate commerce, and control federal spending. It also holds the authority to impeach federal officials and approve treaties. This institution is vital for maintaining the balance of power within the U.S. government.
