Gov. Pat Quinn was among the attendees at a private fundraiser for President Obama on Wednesday night.
The Democrat was seen at the home of media mogul Fred Eychaner chatting with Blair Hull, whom Obama defeated in the 2004 Senate primary. The Chicago Tribune wrote a profile of Eychaner back in 2005.
Also spotted was Illinois Attorney General Lisa Madigan, who earlier in the day revealed her list of the state's top consumer complaints of 2011. Obama identified her as his former seatmate in the Illinois Legislature.
The president also welcomed Sen. Dick Durbin and Sen. Claire McCaskill of Missouri, whom he called "sort of a carpetbagger here."
Outside, several hundred people stood on the sidewalk hoping for a glimpse. One sign spotted mockingly labeled the event a "Solyndra board meeting," referencing the solar cell company that received a loan guarantee and ultimately went bankrupt.
A Ron Paul campaign sign was also spotted.
The event at the Eychaner home followed an event and concert at the University of Illinois at Chicago's UIC Forum, where he told supporters the upcoming election presents voters with a clear choice on where they want to take the country.
