1/4/19 Pocket veto
A pocket veto is legislation passed in the last 10 days of Congress’ session, which the President doesn’t sign, and is therefore not enacted. The U.S. Constitution requires that laws enacted by Congress must be signed into law or vetoed by the President within 10 days.
Congress must be in adjournment in order for a pocket veto to take effect. If Congress is in session and the president fails to sign the bill, it becomes law without his signature. U
