I'll look this up for you. Your U.S. representative in Illinois's 5th Congressional District is **Mike Quigley (D)**. Michael Bruce Quigley is an American politician serving as the U.S. representative for Illinois's 5th congressional district since the April 7, 2009 special election, and he is a member of the Democratic Party. The district covers parts of Cook and Lake counties, and includes all or parts of Chicago, Inverness, Arlington Heights, Barrington Hills, Des Plaines, Palatine, Mount Prospect, Deer Park, Kildeer, Lake Zurich, Long Grove, and North Barrington. A few additional notes: - The district includes most of Chicago's North Side and several of its western suburbs. - Quigley is currently running for mayor of Chicago in the 2027 election. - All U.S. House districts, including the 5th Congressional District of Illinois, are holding elections in 2026, with the general election on November 3, 2026. If you'd like his contact information or district office details, you can visit his official House website (quigley.house.gov).

The response correctly identifies Mike Quigley (D) as the U.S. representative for IL-05, matching the ground truth. However, it contains some fabricated claims (e.g., Quigley running for mayor in 2027) that are not part of the core answer.
