A spokeswoman for Pat Quinn says the Illinois governor is "concerned" about an architect's choice to use nearly $670,000 copper-plated wooden doors as part of a Capitol renovation project. Quinn spokeswoman Brooke Anderson said yesterday that the governor believes any capital projects should be conducted in a "prudent and cost-effective manner." Critics have said the doors are too costly for the state when the Illinois pension fund is underfunded by $100 billion dollars. The building is a National Historic Landmark. The doors that were replaced were made of glass and metal.
