A Quick Primer: How Bill Introduction Works in U.S. Congress#

Before we dive into who writes and introduces bills, it’s important to understand the basic formal rules for bill filing:

• In the U.S. House of Representatives, members introduce bills by placing a printed copy in the “hopper,” a wooden box located near the clerk’s desk.
• In the U.S. Senate, members introduce bills by presenting them to the Senate clerk on the floor, or by submitting them in writing when the Senate is in session.
• Only sitting, elected members of the House or Senate may formally introduce a bill. No other person (including the president, private citizens, or lobbyists) can file a bill directly.
• Bills may have one primary sponsor and any number of co-sponsors, who sign on to signal their support for the proposal.

Who Introduces the Majority of Congressional Bills?#

As noted above, there are two layers to this answer: the formal sponsors of all bills, and the informal stakeholders who write most bill text before it is filed.

Formal Sponsors: All Bills Are Introduced by Elected Members of Congress#

Formally, 100% of bills introduced in Congress are sponsored by a sitting Representative or Senator.

• Data from GovTrack.us for the 118th Congress (2023-2024) shows that over 14,000 bills were filed in the first 18 months of the session, all by elected members.
• On average, a House member introduces 10 to 15 bills per two-year session, while a Senator introduces 25 to 35 bills per session, as they represent larger, statewide constituencies.
• Members introduce bills for a wide range of reasons beyond passing legislation, including:
  • Fulfilling campaign promises to their voters
  • Responding to constituent requests for local policy changes (e.g., renaming a local federal post office, funding a regional flood control project)
  • Signaling support for a high-priority issue for their political party
  • Elevating public awareness of an underdiscussed policy problem

Informal Drafters: Where Most Bill Text Originates#

While only members can formally introduce bills, the vast majority of bill text is written by external stakeholders, per 2023 data from the Congressional Research Service (CRS) and the Congressional Management Foundation (CMF):

1. Executive Branch (30% of major policy bills) The White House and federal agencies are the largest source of draft text for high-priority national legislation. For example, the president’s annual federal budget proposal is drafted by the Office of Management and Budget, then introduced by a member of the president’s party in Congress. Federal agencies like the FDA or Department of Transportation also draft regulatory updates and then work with friendly members to get them filed.
2. Lobbyists and Interest Groups (25% of all bills) Industry associations, advocacy nonprofits, and professional lobbyists often write full draft bills aligned with their policy priorities, then pitch them to members for sponsorship. For example, a 2022 investigation found that 120+ bills rolling back environmental regulations were drafted by fossil fuel industry lobbyists before being introduced by members of Congress.
3. Constituents and Grassroots Organizations (20% of all bills) Ordinary voters, local community groups, and grassroots advocacy campaigns frequently write draft bills focused on local or niche policy issues, then work with their representative’s office to get them filed. A 2022 CMF survey of congressional staff found that 78% of members will consider sponsoring a bill if it is supported by a large share of their constituents.
4. State and Local Governments (10% of all bills) Groups like the National Governors Association, National League of Cities, and state legislative caucuses draft model bills to address intergovernmental policy needs (e.g., adjusted Medicaid funding rules, infrastructure grant allocations) and ask members of their state’s congressional delegation to introduce them.
5. Congressional Staff and Nonpartisan Experts (15% of all bills) The remaining share of bill text is drafted by members’ personal legislative staff, committee staff, or nonpartisan analysts from the CRS, Congressional Budget Office, or Government Accountability Office for internal party policy priorities.

Common Misconceptions About Congressional Bill Introduction#

1. Misconception: Ordinary citizens can formally introduce bills in Congress Correction: Only elected members of the House and Senate can file bills, but private citizens can draft bill text and work with their representative to secure sponsorship for their proposal.
2. Misconception: Most bills are written by the members who sponsor them Correction: Most members have small legislative teams and limited policy expertise for niche issues, so they rely heavily on pre-written drafts from external stakeholders.
3. Misconception: Bills are only introduced if they are likely to become law Correction: Less than 3% of introduced bills become law. Many bills are filed as messaging tools to signal support for an issue to voters, or to start a public conversation about a policy gap.

Why This Matters for Ordinary Voters and Advocates#

Understanding who introduces and writes congressional bills helps you engage more effectively in the legislative process:

• If you want to advocate for a specific policy change, you don’t need to wait for your representative to propose it: you can draft a short policy proposal or full bill text, gather support from other local voters, and request a meeting with your representative’s legislative staff to ask for sponsorship.
• You can track the origin of bills your representative sponsors to identify potential conflicts of interest (e.g., a bill that benefits a large corporate donor who drafted the text).
• You can prioritize supporting bills that originate from grassroots and constituent-led groups, rather than corporate or special interest lobbyists, if that aligns with your values.

Frequently Asked Questions#

Q: Can the president introduce a bill in Congress?#

A: No, the separation of powers prevents executive branch officials from formally introducing legislation. But the president can publicly request that Congress pass a specific policy, and work with members of his political party to draft and introduce a bill aligned with his proposal.

Q: What is a companion bill?#

A: A companion bill is a bill that is introduced in both the House and Senate at the same time, usually by members of the same party, to speed up the legislative process and signal broad, bicameral support for the proposal.

Q: How many co-sponsors can a bill have?#

A: There is no limit to the number of co-sponsors a bill can have. Bills with 100+ co-sponsors are generally seen as having broad, bipartisan support and are more likely to be considered for a vote.

Q: Can a member introduce a bill they do not support?#

A: While there is no formal rule against this, members almost exclusively sponsor bills they support, as sponsorship is a public position that is tracked by voters, advocacy groups, and political opponents.
