WASHINGTON--Vice President Biden is returning to Chicago on Aug. 20 to headline a fund-raiser for freshman Rep. Debbie Halvorson (D-Ill.) at the Custom House, 500 S. Dearborn.

Host committee in formation includes Joe Bohne, Dennis Hopkins, Mike Mullen, Joseph Perry, Steve Magruder, Balvinder Singh and State Sen. A. J. Wilhelmi
