Sources: USAspending.gov: contract obligations by parent company (award types A–D); FEC: PAC contributions to candidates (pas2 bulk files); Senate Lobbying Disclosure Act filings (lda.gov REST API); Committee rosters: the congress-legislators project. Contracts are obligations (money the government committed) in fiscal years ending September 30, summed over each company's own recipient records in USAspending by name, including subsidiaries listed on its page; joint ventures are left out so no contract is counted twice. PAC totals are checks from the company's own PAC to candidates on the ballot, as on this site's PAC pages; a company whose PAC gave under $100,000 in a cycle shows none for that cycle. Lobbying uses the same reconciliation as the Lobbying pages. Committee seats from the congress-legislators project's current roster (119th Congress). Contracts, PAC checks and lobbying are all legal and publicly reported. This page shows them side by side; it does not claim that any gift or lobbying won a contract. Built 2026-11-05.
