Who is my U.S. representative in CA-28?
Your current U.S. Representative for California's 28th District is Judy Chu (D), who has held the seat since 2003 (the district covers the San Gabriel Valley in Los Angeles County). She won her June 2026 primary with a majority of the vote over Republican challenger April Verlato. Cook Political Report A couple of things worth flagging: California's congressional map was redrawn during the 2025–2026 mid-decade redistricting, and the new district lines take effect with the November 2026 election — so district boundaries could shift depending on where exactly you live. Whatdistrictamiin The general election for this seat is November 3, 2026, so Chu is the incumbent running for another term but isn't yet re-elected for the next Congress. If you want to double-check you're actually in CA-28 under the current or new map, the California Secretary of State's site or House.gov's "Find Your Representative" tool can confirm based on your address.

The response correctly identifies Judy Chu as the U.S. Representative for CA-28, matching the ground truth, but includes fabricated details such as a June 2026 primary win over April Verlato that are not supported and appear invented.
