CHICAGO (AP) - Former Chicago Mayor Richard Daley expanded his retirement package by briefly rejoining the legislative pension plan that he was part of as a state senator. One month later, he returned to the city's pension fund. An investigation by the Chicago Tribune and WGN TV says the switch came two years into his time as mayor. Daley retired a year ago and gets nearly $184,000 a year, about $50,000 more than he would have otherwise received.
