Federal spending in CA-04: California's 4th congressional district
USAspending caveat. Figures are obligations reported by federal agencies to USAspending.gov, not payments. In USAspending's words: "An outlay occurs when federal money is actually paid out, not just promised to be paid ('obligated')." "Every agency has a Senior Accountable Official who must officially certify that the quarterly financial data submitted by their agency is accurate and complete." "If there are any discrepancies in procurement data, FPDS is the authoritative source." Contract data for the Department of Defense and the U.S. Army Corps of Engineers is published with a 90-day delay. Data loaded 30 Sep 2026.
