How can the President of the United States limit the legislative powers of Congress?

The President of the United States can limit the legislative powers of Congress through the use of the presidential veto. When Congress passes a bill, the President has the authority to reject it. This veto power is a significant check on legislative action, allowing the President to prevent the enactment of laws that may be deemed undesirable or contrary to the President's policy goals. The veto can stimulate negotiation between Congress and the President, influencing the legislative process and potentially leading to modifications of the proposed laws.

In cases where the President exercises this power, Congress can attempt to override the veto, but doing so requires a two-thirds majority in both the House of Representatives and the Senate. This effectively allows the President to hold considerable influence over the legislative agenda, significantly impacting Congressional effectiveness in enacting laws.
