How a bill becomes law — and how we track it

Roughly 10,000 bills are introduced in each two-year Congress. A few hundred become law. This is the path every one of them must take — and at each stage, the exact update @USBillTracker posts, generated from the official record at Congress.gov and checked every hour.

The path of a bill

Seven stages from idea to law

The labels in the gold-tagged boxes are the feed's actual post types — the same wording you'll see on your timeline when a bill takes that step.

  1. Introduction

    A Representative or Senator introduces the bill, and it receives its number — H.R. for House bills, S. for Senate bills — and is referred to the committee(s) that own its subject. Thousands of bills start here; most never move again.

    The feed deliberately doesn't post introductions — at ~10,000 per Congress they would drown out everything that matters. A bill enters the feed when it starts moving.

  2. Committee

    Committees are where Congress does most of its real work — hearings, amendments ("markup"), and the decision whether the bill deserves the chamber's time. Most bills die here, quietly, by simply never being scheduled.

  3. First chamber: floor debate and vote

    The bill reaches the floor of its home chamber, is debated, possibly amended, and voted on. A simple majority passes it — and sends it across the Capitol to the other chamber, where the whole process repeats.

  4. The Senate's 60-vote gate

    In the Senate, debate on most legislation can only be ended by cloture — which takes 60 votes, not 51. This is the filibuster in practice: a bill with majority support can still stall forever if it can't find 60 votes to close debate. The feed tracks each cloture motion as it's filed, and whether it succeeds.

  5. Two chambers, one text

    The Constitution requires both chambers to pass identical text. If the second chamber amended the bill, the chambers either trade amendments back and forth ("ping-pong") until one side accepts, or convene a formal conference committee to negotiate a single compromise text that both chambers then vote on again.

    ✅🏛️ Agreed To Other Chamber's Amendments 📝 Agreed To With A Further Amendment 🤝 Conference Requested 🤝 Conference Report Agreed To
  6. The President's ten days

    Once both chambers have passed identical text, the bill is presented to the President, who has ten days (Sundays excepted) to act: sign it into law, veto it and send it back, or do nothing — in which case it becomes law anyway, unless Congress has adjourned, when silence becomes a pocket veto.

  7. The override: Congress's last word

    A vetoed bill isn't necessarily dead. If two-thirds of both chambers vote to override, the bill becomes law over the President's objection — one of the hardest thresholds in American politics to reach.

Not everything is a bill

Bills, joint resolutions, and the resolutions that aren't law

Congress votes on four kinds of measure, and only two can become law. The feed tracks all of them — and always says which kind you're looking at. Resolution outcomes post as ✅🏛️ Agreed To rather than "passed", matching the official record's own language.

* A joint resolution proposing a constitutional amendment is the exception: it skips the President and goes to the states, needing ratification by 38 of 50.
Type of legislation Coding House vote Senate vote President signs Force of law?
Bills H.R. / S. Yes
Joint resolutions H.J.Res. / S.J.Res. ✓ * Yes
Concurrent resolutions H.Con.Res. / S.Con.Res. No
Simple resolutions (House) H.Res. No

What a post looks like

Anatomy of an update

Every post follows the same discipline: the bill, its sponsor and committees; the dated action, in the record's own terms; and what honestly comes next. When a bill reaches the President, the feed states the real constitutional clock.

A real post from the feed. Vote results, dates and committee names come from the Congress.gov record verbatim; AI-written summaries, when included, carry an [AI-Generated] label.

The price tag: CBO scores

When the nonpartisan Congressional Budget Office has estimated what a bill would cost, the post carries a “Budget impact:” line — the figure exactly as it appears in the official record. When it hasn't, there's no line. The feed never estimates costs itself and never rounds, summarizes or interprets a score: it's CBO's number or nothing. For students, those little lines are a standing lesson in how Congress prices its own ideas.

Where the data comes from

Congress.gov API — the Library of Congress's official legislative data service
Bill status, actions, titles, summaries and committee data for the current (119th) Congress. The feed polls it every hour, classifies each new action against a state machine of the legislative process, and posts the steps that matter. Ambiguous records are logged and skipped — the feed never guesses on air.

Now watch the other system

The EU makes law by a very different route — two co-legislators, no filibuster, and negotiation behind closed doors. Seeing both side by side is the point.
