What is the main role of a U.S. Senator?

The primary role of a U.S. Senator is to represent the interests of their state in the federal government. Each state elects two senators who serve staggered six-year terms in the Senate, ensuring that each state has a voice in legislative matters at the national level. This representation includes advocating for state-specific issues, needs, and concerns, and helping to shape federal policy in ways that benefit their constituents.

While proposing amendments and drafting treaties are responsibilities of senators, these duties fall under their broader role as lawmakers. Overseeing local governments is not typically a function of a senator, as this responsibility generally lies with state and local officials. Thus, the focus on state representation underscores the essential purpose of the Senate as part of the United States Congress.
