How does Congress work or check the other two branches of government?

Congress checks the other two branches of government through its legislative powers and oversight functions. It can pass laws that can limit the executive branch's authority, reject presidential appointments, and override presidential vetoes with a two-thirds majority in both chambers. Additionally, Congress has the power to investigate and hold hearings on the actions of the executive branch, ensuring accountability. It also plays a critical role in approving budgets and funding, which can influence executive actions.
