Final answer:
The final step before a national bill becomes a law is for it to be presented to the President, who can either sign it or return it with objections to the original house. If two-thirds of both houses of Congress agree to pass the bill after reconsideration, it becomes law. If the President does not take any action on the bill within ten days, it automatically becomes law.
Step-by-step explanation:
The final step before a national bill becomes a law is for it to be presented to the President of the United States. According to the Constitution, if the President approves the bill, they will sign it and it becomes law. However, if the President does not approve the bill, they can return it to the original house with their objections.
If the bill is returned, both houses of Congress must reconsider it. If two-thirds of each house agrees to pass the bill again, it is sent to the other house for their reconsideration. If the bill is approved by two-thirds of both houses, it then becomes law. This process ensures that there is a system of checks and balances, preventing any one branch of government from having too much power.
In some cases, if the President does not take any action within ten days (excluding Sundays), the bill automatically becomes law. However, if Congress adjourns before the ten days are up, and the President does not sign the bill, it does not become law.
