Twenty aldermen, including members of the City Council's black and Hispanic caucuses, say a Chicago casino represents a revenue stream that could be used to improve the city's infrastructure.
"Infrastructure in the neighborhoods we represent are crumbling," said 21st Ward Ald. Howard Brookins.
"We need to understand our state is making significant investments in every part of Illinois, every city," said Gov. Quinn.
Mayor Emanuel has also urged the governor to allow legalized gambling to expand into the city as a way to generate jobs and revenue.
