The Illinois Senate passed a gambling expansion bill Wednesday that would bring five new casinos to the state, including one in Chicago.

The bill, SB 1739, passed out of a Senate committee back in March and aims to appease some of Gov. Pat Quinn's regulatory concerns that led him to veto previous gaming legislation by banning gaming licensees from making political campaign contributions. The bill, if passed by the House and signed by the governor, would also legalize internet gambling and allow slot machines to be installed at Illinois race tracks.

Chicago Mayor Rahm Emanuel, who supports a gambling expansion bill and Chicago casino, released the following statement in response to the bill's passage in the Senate:

I applaud the Illinois Senate for taking action on the gaming bill by passing the bipartisan bill today. Specifically I want to thank Senator Terry Link and Senate President John Cullerton for working to strengthen the bill. This important legislation will provide needed resources to Chicago Public Schools to improve the lives of thousands of Chicago students. I urge the House to take swift action on the gaming bill.

The Illinois Revenue and Jobs Alliance also applauded the bill's passage:

The Illinois Senate voted today to create thousands of jobs and generate sorely needed revenue for our state. With the passage of Senate Bill 1739 – which includes strong ethical safeguards and oversight – construction workers, farmers, horse breeders and other hard-working Illinoisans can look forward to more opportunities that will help create a brighter future.

But state gaming officials say they are concerned about the implementation of the bill's provisions. During a Senate Executive Committee hearing in April, Illinois Gaming Board Chairman Aaron Jaffe said he had a "whole notebook" of concerns and questions about the bill, saying that he does not have the staff to do the regulations the legislation would require.

“I’m interested in regulation. If they are really interested in regulation, we ought to sit down and talk,” Jaffe said. “Whether it was a dog-and-pony show, I don’t know.”
