What is a "pocket veto"?

A "pocket veto" refers specifically to a situation in which the President neither signs nor formally rejects a bill within a ten-day period while Congress is adjourned. Under these circumstances, the bill is effectively "put in the pocket" and does not become law. This mechanism allows the President to effectively veto a bill without issuing a formal veto.

The unique aspect of the pocket veto is that it can only occur when Congress is not in session, meaning the President's inaction leaves the legislation in limbo. If Congress were in session, the President would need to take action to reject the bill formally or it would automatically become law if not signed.

Other options focus on different types of veto actions or congressional procedures, but they do not capture the specific nature of a pocket veto. This understanding of veto powers is crucial for recognizing how the dynamics between the executive and legislative branches operate within the framework of American government.
