About
HillGraph
HillGraph is a congressional staffing intelligence platform. We collect, structure, and connect public data on the people who work in Congress, the offices they serve, their compensation, and their privately-funded travel.
What we do
Congressional staffers shape policy but are largely invisible in public data. The names that move legislation rarely appear in the legislation. HillGraph makes that information accessible and searchable, connecting staffers to offices, salary records, travel disclosures, and the organizations funding congressional travel.
We are read by investigative reporters, policy researchers, advocacy organizations, and government-affairs teams who need to know who is in the room before the meeting starts.
The record
Five interlocking sections, refreshed daily from primary sources.
- People
- Every staffer who has appeared on a House or Senate disbursement record since 2008 — with title, office, tenure, and compensation arc.
- Offices
- Member offices, committees, and leadership shops — their rosters, payroll trends, and the alumni who have moved on to K Street, the executive branch, or back to the Hill.
- Trips
- Privately-funded travel disclosed under the Honest Leadership and Open Government Act — destination, funder, dates, and the staffer on the trip.
- Trip Funders
- The organizations paying for those trips, with their FARA status when they were paying, their lobbying disclosures, and the Hill offices they touched.
- FARA
- Foreign Agents Registration Act filings — registrants, foreign principals, and the contacts they reported with congressional offices.
Sources
Hillgraph is built entirely on public records. We do not republish third-party datasets, and we do not buy data we cannot verify against an original filing.
- House and Senate Statements of Disbursements
- Senate Office of Public Records (lobbying & travel)
- Clerk of the House — privately-funded travel filings
- DOJ FARA Registration Unit
- House and Senate ethics committee reports
- Committee rosters and assignment records

Editorial principles
Show the gaps
Empty fields are marked, not guessed. A missing salary is rendered as missing — never as zero.
No editorial spin
We classify by chamber and committee, never by ideology. The data is the story; the angle is the reader's.
Corrections are public
Errors are fixed in place with a dated note. The history of every record is preserved.
