when may the president of the united states exercise a pocket veto
Pocket veto The Constitution limits the president's period for decision on whether to sign or return any legislation to ten days (not including Sundays) while the United States Congress is in session. A return veto happens when the president sends a bill, along with his objections, back to the house of Congress from which it originated. Congress can override the veto by a two-thirds vote of both chambers, whereupon the bill becomes law. If Congress prevents the bill's return by being adjourned during the 10-day period, and the president does not sign the bill, a "pocket veto" occurs and the bill does not become law. Congress can adjourn and designate an agent to receive veto messages and other communications so that a pocket veto cannot happen, an action Congresses have routinely taken for decades. If a bill is pocket vetoed while Congress is out of session, the only way for Congress to circumvent the pocket veto is to reintroduce the legislation as a new bill, pass it through both chambers, and present it to the President again for signature. On the other hand, Congress may override a regular veto without introducing new legislation through the process described in the U.S. Constitution. James Madison became the first president to use the pocket veto in 1812.[5]
