SPRINGFIELD -- Illinois lawmakers have approved the state's first limits on the size of political contributions, with one key exception.

The legislation would still let major political leaders donate as much money as they want in general elections.

The measure passed 36-22 Friday. It now goes to Gov. Pat Quinn, who hasn't said whether he'll sign it.

Opposition comes mostly from Republicans who argue the limits should fully cover party and legislative leaders.

Government watchdog groups also said they were dissatisfied. But they agreed to support the measure after concluding they could not pass a stronger bill.
