Who makes federal laws?

Why this is the answer

Federal laws are made by Congress, and the three accepted answers are three names for the same body: Congress, the Senate and the House of Representatives together, or the national legislature. A federal law usually applies to every state and everyone in the country, which is what separates it from a state law. Either chamber can propose a bill. It goes first to a committee that studies it and often changes it, then to the full chamber. When the two chambers pass different versions, a conference committee with members of both writes the final text and sends it back for approval. Only then does it reach the President to be signed. Memory hook: Congress makes the law, the President signs it, and signing is not making.
