Quinn received the cash just before he rewrote a law to benefit the union at McCormick Place.
The governor denies that the donations had any impact on his decisions.
"In no way, shape or form," said Quinn. "In all the things I've done as governor, lieutenant governor, and state treasurer, I follow my conscience. I always do the right thing. I always try to do what I think is best for the public. I've done that in this case and in every other case."
Quinn's challenger, Republican State Senator Bill Brady, is calling on Attorney General Lisa Madigan to investigate the donations.
