JB Pritzker are trading blame over a newly signed police and fire pension bill that could cost Chicago taxpayers $11 billion over 30 years. An internal memo shows Johnson’s office warned Pritzker’s team about the financial impact, while Pritzker says Johnson never asked him to veto or change the bill.
