I'll look that up for you. Your U.S. representative for **California's 39th Congressional District (CA-39)** is **Mark Takano (D)**. California's 39th Congressional District in the United States House of Representatives is represented by Mark Takano (D). One important thing to note: 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. The boundaries of this district will change as a result of California Proposition 50, which voters approved on November 5, 2025. So the district's boundaries are set to change following recent redistricting. If you'd like, I can help you confirm your specific representative by ZIP code or address, since your district assignment may depend on exactly where you live.

The response correctly states that Mark Takano (D) is the representative for CA-39, matching the ground truth, though it adds some extraneous (and questionable) claims about Proposition 50 dates.
