To make a bill become a law in US constitution, every branch of the government has to support and agree to the
law. First, both houses in congress, the legislative, should come out the idea for a bill that can be a law. Secondly, the president reviews the bill and decide sign it into law or not. If the Executive vetoes it, this bill cannot become a law without the president’s signature unless it has 2/3 vote in each house. Finally, the judicial system will review the bill with the constitution. A law is removed if it is unconstitutional.
