Congress can override a presidential veto by having a two-thirds majority vote in both the House of Representatives and Senate, thus enacting the bill into law despite the pâ¦resident's veto. Answered by The WikiAnswersÂ® Community.
Bills are introduced in either the Senate or House of Representatives. After passing both chambers with a majority vote of approval, the bill is presented to the president. If the president approves the bill, it becomes law. However, the president, as head of the executive branch, also has the ability to veto the bill. From 1789 to 2013, presidents have vetoed 2,564 bills.
