If a bill is vetoed, what is the next step that can occur?

When a bill is vetoed by the President, Congress has the option to attempt to override that veto. This can occur if both the House of Representatives and the Senate vote to pass the bill again, but this time with a two-thirds majority in both chambers. This procedure is built into the legislative process to ensure a balance of power between the branches of government. If successful, the bill becomes law despite the President's objection.

The other options do not accurately reflect the legislative process following a veto. Discarding the bill permanently would preclude any further action, which is not inherently the case as Congress may revisit the bill. Rewriting by the Senate doesn’t automatically follow a veto; such actions might happen, but the bill's original form is also subject to lobbying or further discussions without starting anew. Finally, reintroducing the bill in the next session is not necessary, as Congress can attempt to override the veto within the same session if time allows. Thus, overriding the veto with a two-thirds majority is the correct and actionable next step.
