A legislator is an elected official responsible for making laws and shaping public policy. They work in legislative bodies, such as Congress in the United States or parliaments in other countries, where they propose, debate, and vote on legislation. Legislators represent the interests of their constituents, the people who live in their electoral district. In addition to creating laws, legislators also oversee government budgets and hold hearings to investigate issues affecting their communities. They often serve on committees that focus on specific areas, such as education, healthcare, or transportation, allowing them to specialize in topics important to their constituents.
