A pocket veto is absolute — Congress cannot vote to override it because the bill never formally returns.
If Congress goes home before the President's 10-day window to sign a bill runs out, the President can kill it by simply doing nothing.
Bills passed in a session's final days are uniquely vulnerable, giving the President quiet power over late legislation.
The President has 10 days (excluding Sundays) to sign or veto a bill once it arrives.
If Congress adjourns during that window and the President does nothing, the bill dies instead of becoming law.
