Follow the Money
Which industries fund Congress?
Follow the money by sector. Each industry below aggregates the companies that fund members of Congress — and maps to the federal agency that sector lobbies. The same firms that depend on an agency's budget often fund the lawmakers who oversee it.
Pick a sector to see its top corporate funders and exactly which members of Congress they fund, ranked by amount. We map each sector to its federal counterpart — defense to the Pentagon, health care to HHS, finance to Treasury — so you can connect the money to the agency.

About this data
Campaign finance figures are aggregated from public Federal Election Commission filings (public domain). Stock trades, lobbying, and contract figures are derived from disclosures compiled by QuiverQuant. Contributions are grouped by the donor's reported employer — they are not OpenSecrets industry clusters, and the totals combine individual contributions with affiliated PAC activity where reported.
Contributions and disclosures are not proof of influence. They show who gave and what was reported, not why a member voted a particular way. Amounts reflect the cycle or as-of dates noted beside each figure and may be revised as later filings are processed.
