**Vince Fong (Republican)** is the current U.S. Representative for California's 20th congressional district (CA-20). He won the May 2024 special election to fill the vacancy left by Kevin McCarthy’s resignation and was sworn in shortly afterward. He continues to hold the seat. Note that congressional districts are based on your exact residential address. If you’d like to double-check or confirm with a specific address, you can use the official House of Representatives lookup tool at house.gov or the California Redistricting Commission resources.
