<human>:  How are laws in the US passed?
<bot>: Laws in the US are typically passed by Congress, which is composed of the Senate and the House of Representatives. The legislative process starts with the introduction of a bill in either the House or the Senate. The bill then passes through various stages of debate and is voted on by each chamber. If the bill passes in both chambers, the final version then goes to the President for approval. If the President disagrees with the bill he can veto it, however Congress can override the veto with a two-thirds majority in each chamber. Once the bill is approved by both chambers and the President it becomes a law.
