A Bill is Introduced in Congress
Committee Hearings, Reports, and Prints
The congressional committee or subcommittee decides on whether or not to consider the bill; many are not considered and "die in committee." Committees may choose to hold hearings where relevant experts are gathered before the committee to testify, giving their opinions and relevant data on the subject matter of the bill. Committees can choose to make changes or amendments to the bill with markups. Committees may issue a report to the Congress about their deliberations. Other relevant materials may be gathered and published as a committee print.
Floor Action and Debate
Bills that are reported on favorably by committee are brought forward for floor action. If the bill is approved for consideration on the floor it may be debated or amended before being passed by the House or Senate. All congressional actions are published verbatim in the Congressional Record. Once the bill passes one chamber of Congress it becomes an engrossed bill or act.
Conference Committee Reports
The act goes to the other chamber of Congress and proceeds through a similar process of being referred to a committee, marked-up, debated and amended. If the bill is not substantially changed then it can be passed by the second chamber and sent to the President.
If the bill is substantially changed than a conference committee may be convened. The conference committee is composed of members from both chambers who try to agree on a compromise for the bill. If they are successful, then a conference report is issued with a version of the agreed upon bill and an explanation for any changes. This newly amended bill must be approved, without changes, by both the House and the Senate before being sent to the President.
The final version of the bill is called the enrolled bill.
The enrolled bill is sent to the President for signature. The President must sign the bill within 10 days to become law, or the President can choose to veto the bill and send it back to Congress with a veto message. Congress can override a veto with 2/3 majority vote from both chambers. If the President does not sign the bill within 10 days, and congress is in session, then the bill automatically becomes law. If the President doesn't sign the bill, and Congress is not in session, then the bill fails. This is known as a pocket veto. When the President signs a bill it immediately becomes law, and a signing statement may be issued to accompany it. The bill is assigned a Public Law number.
Slip Laws, Statutes, and Codes
When a bill becomes a law and is assigned a Public Law number it is first published by the Office of the Federal Register as slip law. The law will next be published in sequential order with other passed laws from the congressional session in the Statutes at Large. Statutes at Large indicates if and how the law is codified by the Law Revision Counsel in the United States Code.
Congress grants authority to executive agencies, such as the Department of Agriculture, to interpret the Statutes at Large and US Code in the drafting of administrative law (general rules and regulations). This administrative law is published and organized by agency in the Code of Federal Regulations (CFR). The CFR is revised annually. Any proposed changes are published daily in the Federal Register.
