Gov. Pat Quinn is days away from the deadline to decide if he'll sign a gambling expansion bill, but he says he's not sure what he'll do. Quinn says that he's going through the bill line by line and will make a decision by Tuesday. That's when he must decide.

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 gets 60 days to decide to sign, veto or propose changes.

Previously, Quinn has said that he likely won't sign the bill as it is and says his biggest concern about it is ethics.
