When a president refuses to sign a bill, the outcome usually depends on how long Congress stays in session. If Congress is still in session and the president takes no action for 10 days, the bill becomes law without a signature; if Congress adjourns during that 10-day window, it can be blocked by a pocket veto instead.

What it means

A president does not have to sign every bill to make it law. In the U.S. system, a bill can become law by:

  • Direct signature.
  • No action for 10 days while Congress remains in session.
  • Override of a regular veto by two-thirds of both chambers.

Two main outcomes

  1. Regular veto path.
    If the president actively rejects the bill, Congress can try to override that veto with a two-thirds vote in the House and Senate.
  1. Pocket veto path.
    If the president does nothing and Congress adjourns before the 10 days are up, the bill dies and cannot be overridden.

In current news

Recent coverage shows this rule in action: President Trump refused to sign a bipartisan housing bill, creating a standoff over whether Congress could still push it into law or whether the bill would stall.

Plain-English version

Think of it like this: a bill has to survive either the president’s signature, a timeout with Congress still working, or a congressional override. The only truly fatal move is a pocket veto during adjournment.

Example

If Congress passes a bill on Monday and the president does nothing:

  • By Thursday, it still is not law.
  • If Congress is still in session on the 10th day, the bill becomes law automatically.
  • If Congress adjourns before that deadline, the bill can disappear through a pocket veto.

In short, refusing to sign does not always stop a bill; it may still become law unless the president uses a veto effect that Congress cannot override in time.
