When a U.S. president vetoes a bill, the bill is rejected and sent back to Congress with the president’s objections; Congress can then try to override the veto with a two‑thirds vote in both chambers, and only then can it still become law. If Congress cannot reach the two‑thirds threshold in either the House or the Senate, the bill simply dies and does not become law.

What a veto actually is

  • A veto is the president’s formal rejection of a bill passed by both the House and Senate.
  • The Constitution (Article 1, Section 7) gives the president 10 days, excluding Sundays, to sign or veto a bill once it is presented.
  • If the president vetoes, the bill is returned to the chamber where it started, with a written message explaining the reasons.

What happens in Congress next

  • The chamber that first passed the bill must decide whether to vote again to override the veto.
  • To override, at least two‑thirds of members voting in that chamber must approve the bill despite the president’s objections.
  • If the first chamber succeeds, the other chamber must also approve it by a two‑thirds vote; only then does the bill become law “notwithstanding the objections of the President.”

If Congress cannot override

  • If either chamber fails to reach two‑thirds, the veto stands and the bill does not become law.
  • Overrides are possible but historically rare , so most vetoed bills never take effect.

Regular veto vs. pocket veto

  • A “regular” veto is when the president actively returns the bill with objections while Congress is in session.
  • A “pocket veto” happens if the president takes no action for 10 days and, during that period, Congress adjourns; in that case, the bill simply expires and does not become law, and Congress cannot override it because it is not in session.

Quick forum-style angle

On civics forums and Q&A sites, people often ask “Does a veto mean it’s over?” The nuanced answer: usually yes , because getting two‑thirds in both chambers is politically difficult, but not impossible—so a veto is more like a very steep hill for Congress to climb than an automatic end to the idea.

TL;DR: When a president vetoes a bill, it is rejected and sent back with objections; Congress can only “rescue” it by overriding the veto with two‑thirds votes in both the House and Senate, otherwise the bill dies.
