The 15th Senate district, in its current borders, crosses three different congressional districts. The portion of the district in Jefferson County, and the city of Whitewater, which is partly in Walworth County, falls within Wisconsin's 5th congressional district, which is represented by U.S. Representative Scott L. Fitzgerald; the remainder of Walworth County and the cities of Janesville and Milton and the eastern part of Rock County fall within Wisconsin's 1st congressional district, which is represented by U.S. Representative Bryan Steil; the remainder of the district, in Dane, Green, and Rock counties, falls within Wisconsin's 2nd congressional district, which is represented by U.S. Representative Mark Pocan.[7]
