How can a President veto legislation?

A President vetoes legislation by returning it to Congress with a veto message, which outlines the reasons for rejecting the proposed law. This constitutional power is outlined in Article I, Section 7 of the U.S. Constitution, where it specifies that after a bill is passed by both houses of Congress, it must be presented to the President. The President has the authority to either sign the bill into law or veto it.

When a President issues a veto, they have the opportunity to communicate their objections and concerns directly to Congress, allowing for a discussion on the issues raised. If a bill is vetoed, it can still become law if Congress overrides the veto with a two-thirds majority vote in both the House and Senate, but the original veto sends a clear message regarding the President's stance.

In contrast, issuing an executive order refers to a different mechanism through which the President can manage operations within the executive branch, but it does not involve the legislative process directly. Dissolving Congress is not a power granted to the President, as the separation of powers maintains distinct functions for each branch of government. Obtaining a majority in the Senate is more relevant to the legislative process and voting rather than the specific mechanism of vetoing legislation.
