Gov. Pat Quinn is questioning his Republican gubernatorial rival's ethics, wealth and stance on minimum wage during his re-election bid.
The Chicago Democrat raised the issues in a story published in Sunday's Chicago Sun-Times.
Quinn has already tried to differentiate himself from businessman Bruce Rauner by playing up the venture capitalist's wealth and views on minimum wage. Quinn wants to raise Illinois' rate. Rauner initially said he wanted to cut the rate, later saying he'd raise it under certain circumstances.
Now Quinn is raising questions about Rauner's business dealings and possible links to Stuart Levine, who was convicted in former Gov. Rod Blagojevich's corruption scandal.
Rauner's campaign says Quinn is playing "political games" and blasts his signing of a pension overhaul cutting benefits for state employees and retirees.
