Who is my U.S. representative in CA-39?
Your current U.S. Representative for California's 39th district is Mark Takano, a Democratwho has represented the district since he was redistricted from the 41st congressional district in 2022. The district covers parts of Riverside County, including Jurupa Valley, Riverside, Moreno Valley, and Perris. Wikipedia Wikipedia A couple of things worth flagging: Takano is running for re-election in 2026, and he faced Steve Manos in the June 2026 primary, winning about 56% to 44%, so he'll appear on the November 2026 general election ballot. Ballotpedia Local Candidates California's congressional map was redrawn during 2025–2026 mid-decade redistricting, and the new district lines take effect with the November 2026 election, so CA-39's boundaries (and possibly who represents it) could shift after this year's election. If you want to double check which district you'll be in going forward, the California Secretary of State's site is the place to verify. Whatdistrictamiin

The response correctly names Mark Takano as the representative, matching the ground truth, but includes fabricated/incorrect details about the 39th district's geography (CA-39 does not cover Riverside County areas like Jurupa Valley/Perris) and unverifiable claims about 2026 elections and redistricting.
