Tracking Lobbying in Congress.

Further right means more giving from the lobbying firms in the pool. Dollars run on a square root scale, which spreads out the many members near the left edge. A member with none on record is a filing state, not a finding.

• The biggest single flow: $13,786,546 from the firms that named HR 1 to the House Committee on the Budget, level with that committee's ordinary share of all lobbyist giving, so what is large here is the bill and not the concentration.
• The largest giver's share: 0.94% of the whole pool comes from AICPA Association of International Certified Professional Accountants. No organization on the board holds a larger share than that one.
• Members reached: All but 2 Reaching 272 of 274 Republicans, all 262 Democrats and all 3 Independents on record.

A bill counts as measured once 5 or more firms named it in a filing and their matched giving reaches $250,000; smaller bills are left out rather than shown as zero. A flow is the giving of the firms that named one bill, set against the ordinary share of all lobbyist money that committee sees, so it is a concentration and never dollars attached to a bill. It is ONE bill and ONE committee of referral. The filings table at the foot of this page leads with whole bills instead: every committee a bill was referred to at once, which is why its top figure is a larger number of a different kind. The pair above sits inside that bill's row. A share of the pool is one organization's own political money against every organization's, both filed under their own names. A member with nothing on record is a filing state and not a finding: the board carries every sitting member and delegate.

Who buys lobbying in the first place, taken across every client on record for the year: how much of it is business, how much is labor, and which sectors spend the most.

All federal lobbying spend reported for 2025, every client on record, $5.51B in all. It is a different pool of money from the giving above.

Business here means companies and business groups together, every sector except labor, advocacy and the unclassified residue. This is what clients paid to lobby across 2025, a different disclosure system from the pool above, which is the political giving of the lobbying organizations themselves. The two are never added together. Advocacy is 2 sectors of the list above, Leadership & Ideological and Pro-Israel, and they account for $13.0M between them; none of that is inside the business figure. Not yet classified is the spend our sector rules did not reach; it includes cross-industry federations such as the Chamber of Commerce, which have no single sector to wear. The count under each row is how many clients filed that spend, which is what separates a sector of a few giants from a sector of many payers.

A lobbying filing names the bills it covers. That filing is the one document both sides of the spread appear in together, so it is where this ledger closes. The filings name 10,029 bills in all, and the 1,703 below are the ones that clear this page's own bar for measurement. One row per bill, led by every committee it was referred to at once, with the rooms behind it a tap away.

The biggest single flows into one committee that also ran at least twice that committee's ordinary share of all lobbyist money: big and far above the usual, not merely big. A flow is one bill and one committee, so its figure can differ from the same bill's row below, which adds every committee the bill was referred to. A high multiple is a reason to read closer, not a verdict.

One row per bill, totalled across its committees of referral with every member counted once. A multiple is the giving that reached the committee against that committee's ordinary share of all lobbyist money; a high multiple is a reason to read closer, not a verdict.
