Roberts has been a vocal critic of Obama's goal to close the prison and instead house detainees in prisons on U.S. soil. When Obama administration officials traveled to Kansas to assess the military prison at Fort Leavenworth as a potential site to house Guantanamo detainees, Roberts urged Defense Secretary Ashton B. Carter to keep the detainees out of Kansas.
"Fort Leavenworth is neither the ideal nor right location for moving Guantánamo detainees," he wrote in an August letter to Carter. "The installation lies right on the Missouri River, providing terrorists with the possibility of covert travel underwater and attempting access to the detention facility."
