How do signing statements affect the legislative process?

Signing statements affect the legislative process primarily by indicating the President's interpretation of a law. When a President signs a bill into law, they often issue a signing statement that articulates their understanding and intentions regarding the law. This can include how they plan to enforce the law, any parts they find problematic, or their views on its constitutionality.

These statements can influence how the law is implemented, as executive agencies may rely on the President's interpretation to guide their actions. While signing statements do not have the power to change the language of the law itself, they may shape the political and legal landscape by signaling how the executive branch will interpret and apply the statute. This can lead to potential conflicts with Congress if lawmakers feel that the President's interpretation diverges from their original intent in drafting the legislation.

The other choices do not accurately describe the role of signing statements. They do not require legislation to be rewritten or automatically nullify existing laws, nor do they empower Congress to override presidential vetoes. Each serves different functions in the legislative process.
