What action does the President take if he/she does not agree with a bill?

When the President does not agree with a bill that has been passed by Congress, the appropriate action is to veto the bill. A veto is the formal rejection of the proposed legislation, and it signifies the President's disapproval. This power is a significant aspect of the checks and balances system in the U.S. government, allowing the executive branch to limit the legislative branch's power.

When a bill is vetoed, Congress has the option to attempt to override the veto. This requires a two-thirds majority vote in both the House of Representatives and the Senate. If successful, the bill can still become law despite the President's objections. However, if the veto is not overridden, the bill does not become law.

The other actions listed, such as ratifying the bill or amending the bill, do not align with the President's options regarding disapproval. Ratification typically refers to the confirmation of treaties or amendments, while amending implies making changes to the bill before it is passed, which is a legislative function rather than an executive one. Ignoring the bill (commonly known as a pocket veto) is a different circumstance where the President neither signs nor formally rejects a bill but allows it to become law without their signature if Congress is in session,
