Your U.S. Representative for California's 4th congressional district (CA-04) is **Mike Thompson** (a Democrat). **A quick note on redistricting:** If you are confused because Tom McClintock used to be your representative, California's congressional maps were redrawn after the 2020 Census. Starting in January 2023, the new 4th district covers Napa and Lake counties, as well as parts of Solano, Sonoma, and Yolo counties. (Tom McClintock now represents the 5th district). You can learn more about his work or contact his office through his official website: [mikethompson.house.gov](https://mikethompson.house.gov/).
