01 · Background

Who they are, where they came from

Mike Thompson represents California's 4th congressional district, a seat he has held since January 1999. The district encompasses all of Lake and Napa counties and portions of Contra Costa, Solano, Yolo, and Sonoma counties in the outer northern San Francisco Bay Area. Thompson chairs the House Gun Violence Prevention Task Force. In that role, he has sponsored the Bipartisan Background Checks Act of 2025 (HR.18), which would expand federal background check requirements for firearm transfers, and the concurrent resolution HCONRES.46 expressing Congress's commitment to related federal responsibilities. On health care access, Thompson has sponsored the CONNECT for Health Act of 2025 (HR.4206), legislation addressing telehealth coverage, which he also introduced in a prior Congress as HR.4189. He has additionally sponsored the Mental Health Research Accelerator Act of 2025 (HR.2084) and the Smoke Exposure Research Act of 2025 (HR.2085). On energy and disaster policy, Thompson sponsored the American Energy Independence and Affordability Act (HR.5862) and the Disaster Resiliency and Coverage Act of 2025 (HR.1105), the latter addressing insurance coverage in disaster-affected areas. He has also sponsored the Agricultural Emergency Relief Act of 2025 (HR.4354) and multiple resolutions supporting National Women's History Month (HRES.280, HRES.1145, HRES.1110).
