Laws are first drafted by either a Member of the House of Representatives or Senate. This draft is called a bill. It is a fairly complicated and rather lengthy process for a bill to become a law. Outlined below is a brief explanation of that process. For more information and a more detailed description, see the How Our Laws Are Made page compiled by the office of the Parliamentarian.

A bill is a written draft of an idea on how to change a law, fix it, or enact a new one. As any bill that is passed will have an impact on thousands of American, the language is chosen carefully and often in consultation with experts. Most of the time a Representative will take his or her bill to a non-partisan office called the House or Senate Legislative Counsel. An attorney who specializes in the legal issues involved in drafting a bill will be on staff to help Representatives with the actual language.

Once the bill is written, the Representative will sign the bill and place it in "the hopper" (the actual box where newly drafted bills are placed) for introduction. After the bill is "dropped" (placing the bill in the hopper) it is assigned a number. Bills from the House of Representatives are numbered H.R. 1 and up and bills from the Senate are numbered S. 1 and up. Other forms of legislation are resolutions, the non-binding expression of Congress' opinion. These are titled H.Res (House resolutions) or S.Res (Senate resolutions) respectively.

The next step in the process is committee action. There are usually two steps in committee action: hearings and markups. A hearing is when Congress invites people to come and testify on the public record with their views of the pending bill or issue. The second phase of the committee process is the markup. The markup is when the Committee actually writes a bill, line by line. The Chairman of the committee or subcommittee will provide the starting legislation, something called the Chairman's mark. The Chairman's mark usually makes changes to the original bill based on concerns brought up at hearings or by individual Members. At a markup, the Committee goes through the bill, line by line, and Members can offer amendments or ask the Committee's staff counsel to clarify certain provisions. This is usually done in open session. Votes are held on amendments, and a vote is finally held on whether or not to report the bill to the House. Then the staff will write the Committee report. If there is opposition to the legislation, individual Members can add their own "additional views" or "dissenting views" to the committee report.

After a bill has been reported out of committee, it will go to the Rules Committee for a hearing. The Rules Committee literally determines how the bill will be considered on the floor of the House (i.e. how long the debate will last, what amendments will be offered, etc.). Non-controversial bills often skip this procedure and are considered under Suspension of the Rules. Suspension bills are only considered for 40 minutes, they can't be amended, and require a 2/3 vote for passage.

Once on the floor, the bill is debated, any amendments are offered and voted on, and a vote is taken on whether or not to pass the bill. Any Member of Congress can come to the floor and speak on a bill, subject to the time restrictions for debate imposed by the Rules Committee.

If the House and Senate pass different versions of the same bill, the legislation will be brought to a conference committee to have the differences resolved. Once the House and Senate have both passed identical versions, it is submitted to the President for signature.  Congress normally knows what the President's reaction to the bill will be. Once the President receives a bill for approval he then has two options, he can sign it, in which case it becomes law, or veto it. After the President has vetoed a bill, he must submit his objections to Congress. If Congress still wants to enact the bill, then two thirds of the House and Senate must approve the bill, thereby overriding the President’s veto.
