What 3 circumstances result in a bill failing to become a law?

All laws in the US begin as bills. In order for a bill to become a law, it must be approved by the: U.S. House of Representatives, the U.S. Senate, and finally the President.

Explanation:

1. In the U.S. House of Representatives the bill cannot pass and become a law if a majority of the Representatives say or select "no", for opposing the bill during the voting.  

2. If it passes, it can still fail in the Senate, and the process is pretty much similar the previous one. The bill is voted on, if the majority votes as “no”, the bill will not go to the President for approval. If the bill passes in the U.S. Senate is ready to go to the President.

3. The President can refuse to sign the bill (veto), so the bill is sent back to the U.S. House of Representatives that will either accept or override the veto.
