I'll look up the current U.S. Representative for California's 12th congressional district. Your U.S. Representative for California's 12th congressional district is **Lateefah Simon**, a Democrat. Lateefah Simon, a Democrat, has represented the district since January 2025. The district was represented previously by longtime congresswoman Barbara Lee, former Speaker of the House of Representatives. (Note: Barbara Lee was a longtime congresswoman for the district, though she was not Speaker of the House — that detail in the source appears to be an error.) CA-12 is a congressional district in northern California. One thing to keep in mind for the future: this Congressional district was established by the voters of California with the passage of Proposition 50 (2025) on November 4, 2025 and will go into effect after the November 2026 elections and upon seating of the 120th Congress, January 3, 2027. So the district boundaries may change after the 2026 elections due to redistricting. If you'd like to confirm this is truly *your* representative, I'd recommend entering your home address at the House of Representatives' official lookup tool (house.gov/representatives/find-your-representative), since district assignments depend on your specific location.

The response correctly identifies Lateefah Simon as the CA-12 representative, but includes a fabricated claim that the district was established by Proposition 50 (2025) and won't take effect until 2027, which contradicts the stated fact that Simon has represented the district since January 2025.
