SPRINGFIELD. (AP) — Illinois Gov. Pat Quinn wants to close two prisons, including a "super max" institution at Tamms.

An administration official said Tuesday that Quinn's budget proposal also calls for closing the maximum security prison at Dwight and six transition centers for inmates nearing their release dates. The official was not authorized to discuss the proposal publicly and would speak only on condition of anonymity.

In all, the facilities house about 2,650 inmates. Closing them would increase crowding in facilities that are already far beyond capacity.

The budget Quinn is scheduled to deliver Wednesday also calls for closing two youth prisons and four facilities operated by the Department of Human Services.

Quinn plans to call for closing the state facilities when he presents his proposal for a new Illinois budget that would slash spending throughout state government, a person familiar with the plan told The Associated Press on Tuesday.

Illinois prisons are severely overcrowded. As of November, 48,620 people were squeezed into space designed for 33,700. The Corrections Department has begun counting areas like gymnasiums when calculating the space available for housing inmates.

The Democratic governor's call for closures could be a repeat of last year, when he said several facilities need to be shut down because lawmakers hadn't given him enough money to run them. They included a prison in Lincoln, a youth prison in Murphysboro and mental institutions in Rockford, Chester and Dixon.

Those closures were avoided when lawmakers approved additional money to keep those and other facilities open.

Quinn has said he'll call for cuts of 9 percent in most state agencies, and he has challenged other statewide officials to cut the same amount from their budgets. The administration says Medicaid spending must be cut by $2.7 billion and that officials must find a way to reduce the amount Illinois spends on pensions each year.

One of the few areas where Quinn wants to increase spending is education. He will propose hiking education funds by $90 million, or about 1 percent, with the money going to early childhood education and college scholarships, the administration says. His proposal also includes a call for closing unneeded tax loopholes as a way of coming up with money to gradually pay billions of dollars in overdue bills.
