How is Congress able to limit the president's ability to influence federal legislation?

Congress can limit the president's influence over federal legislation primarily through its constitutional powers, including the authority to draft, amend, and pass laws. The legislative process requires Congress to approve any proposed legislation, giving it the ability to reject the president's initiatives. Additionally, Congress holds the power of the purse, allowing it to control funding and resources that can impact the implementation of presidential policies. Furthermore, Congress can override a presidential veto with a two-thirds majority vote in both chambers, reinforcing its legislative authority.
