Illinois disability advocates are calling on the state to close six of the state's seven developmental centers.

The activists say the state could save $337 million annually by closing the facilities. Scores of disability advocates took to the Illinois Capitol Wednesday to demand that Gov. Bruce Rauner close all but one of the state's developmental facilities, calling the group homes costly and "antiquated." But those in favor of the facilities say some Illinois residents with developmental disabilities need the services provided by the centers.

Former Gov. Pat Quinn called for the closure of all developmental disability facilities in the state, closing the Jacksonville Developmental Center in 2012. During his campaign, Rauner said he would back calls to keep Centralia's Murray Developmental Center open.
