Gov. Pat Quinn will use all of the alloted time he's been been given to decide on a gambling expansion proposal on his desk.
Quinn has until Tuesday to decide if he'll sign the bill, but said Wednesday that he'll take the weekend to go through the bill line by line before making a decision.
"It's a complicated measure, it's as thick as the Chicago phone book, and we're going through it line-by-line because we have to, and we found some things that need some close attention," Quinn said.
Lawmakers passed a bill earlier this year that would create five new casinos -- a land-based site in Chicago and four more on riverboats. The bill would also allow slot machines at horse racing tracks for the first time.
Quinn said his biggest concerns are integrity and oversight of gamblers and casino owners.
"I always believe the money should go to education. We have to make sure if we have any kind of gambling that the resources and revenue go to things that are important in our society," Quinn said.
Supporters of the gambling measure have said they expect Quinn to veto the proposal and are working to gather enough votes to override him during the post-election session, according to the Chicago Tribune.
