Bill (law) A bill is proposed legislation under consideration by a legislature.[1] A bill does not become law until it is passed by the legislature and, in most cases, approved by the executive. Once a bill has been enacted into law, it is called an act of the legislature, or a statute.
Appropriations Bill. A bill that specifies how much money can be spent on a given federal program. Reviewed by Appropriations subcommittees in both the House and Senate, appropriations bills must also be approved by the full House and Senate before being signed by the president to become law.
