What role does Congress play in the US government?

Congress plays a crucial role in the U.S. government as the legislative branch, primarily responsible for the creation of laws. This function is outlined in Article I of the Constitution, which establishes Congress as a bicameral body consisting of the House of Representatives and the Senate. The process of lawmaking involves several steps, including the proposal of legislation, debate, and voting within both chambers. Once a bill has passed both houses of Congress, it is sent to the President for approval or veto.

In contrast to the other options, Congress does not enforce laws, which is the responsibility of the executive branch led by the President. Similarly, the power to interpret and review laws falls under the judicial branch, not Congress. While Congress does provide oversight and support to the President, it does not serve merely in an advisory capacity; rather, it operates with distinct powers and responsibilities, including the authority to approve budgets, declare war, and confirm appointments to the executive and judicial branches. Thus, the primary function of Congress is indeed the legislative creation of laws.
