CHICGAO, IL - Gov. Pat Quinn has called lawmakers back to Springfield for a one-day special session to reform the state's pension systems. But, so far, he doesn't have a plan beyond that.

Quinn announced Monday that legislators will convene Aug. 17.

He says lawmakers already have legislation on the table that they should consider. That includes a measure pushed by Senate President John Cullerton that addresses two of the state's five pension systems.

Quinn says that's a good start, but he wants a comprehensive deal including a plan that makes suburban Chicago and downstate school districts pay their own pension costs, which the state currently picks up.

Legislative leaders have been deadlocked over how to address the state's $83 billion in unfunded liability.

Republicans have disagreed with shifting costs to schools.
