Answer: If the President agrees substantially with the bill, he or she may sign it into law, and the bill is then printed in the Statutes at Large. If the President believes the law to be bad policy, he may veto it and send it back to Congress.
Explanation: A member of Congress introduces a bill into his or her legislative chamber. ... The president may sign the act of Congress into law, or he may veto it. Congress can then override the president's veto by a two-thirds vote of both the House and Senate thereby making the vetoed act a law.
