Brief Explanations:

In the U.S. system of checks and balances, Congress can override a presidential veto. A presidential veto is when the president rejects a bill passed by Congress. But if Congress, with a two - thirds majority in both the House of Representatives and the Senate, votes to override that veto, the bill becomes law. Debating a bill in both houses is part of the normal legislative process, not specifically a check on presidential power. Making laws without presidential review is not in line with the constitutional process (the president has a role in the law - making process through veto power). Sending a bill back to committees is part of the legislative refinement process, not a check on presidential power.

Answer:

overriding a presidential reversal or veto.
