Answer:
1. Bill is introduced in Congress
2. Bill passes in both-houses
3. Bill is sent to the president
4. President signs or vetoes the bill
Explanation:
The U.S. Congress holds two legislative assemblies: the U.S. Senate and the U.S. House of Representatives. Anybody elected to either of them is entitled to propose a new law.
Once both houses have accepted a bill, they send it to the president, who then analyzes the bill and is able to approve it and sign it into law or veto it.
If the president chooses to veto a bill, Congress can decide to override that veto and the bill turns into a law. But, if the president pocket vetoes the bill after Congress has adjourned, the veto cannot be revoked.
