Question: can the president of the united states veto a bill passed by congress

Answer: Yes, If the President approves of the legislation, then the President signs it into law. According to Article 1. Section 7 of the Constitution, when the President chooses not to sign or does not approve of the bill, the President must return the bill, unsigned, within ten days, excluding Sundays, to the house of the United States Congress in which it originated, while the Congress is in session. The President is constitutionally required to state any objections to the bill in writing, and the Congress is constitutionally required to consider them, and to reconsider the legislation. This action, in effect, is a veto.
