Gov. Mike Beebe defended the Conway Human Development Center today, saying the state investigates any claims of improper patient care at the facility and numerous reviews have found none. A day after the U.S. Department of Justice sought a federal court order to halt new admissions of school-age children to the facility, Beebe also suggested a long-standing disagreement between the state and federal officials over how to care for the developmentally disabled may have prompted the Justice Department action.
