The branch of government responsible for making laws is the Legislative Branch, primarily composed of two chambers: the House of Representatives and the Senate. Together, they create, amend, and enact legislation, which can affect various aspects of public policy and governance in the country. Members of Congress represent the interests of their constituents, engaging in debates, committee work, and voting on proposed laws. The legislative process also involves collaboration with the Executive Branch to ensure that enacted laws can be effectively implemented and enforced.
