Who are my U.S. senators in Washington?
Since you're in Concord, Massachusetts, your two U.S. senators are: Elizabeth Warren (D) — serving since 2013 Ed Markey (D) — serving since 2013 Worth noting: Markey is up for re-election in 2026. He's running for a third full term but has said this would be his last if re-elected. He's facing a primary challenge from Rep. Seth Moulton, with the primary set for September 1, 2026, and the general election on November 3, 2026. Warren's seat isn't up until 2030.

The question asked about Washington senators (Maria Cantwell and Patty Murray), but the chatbot answered with Massachusetts senators, assuming a wrong location and inventing details.
