The U.S. Supreme Court has rejected Arizona's eleventh-hour bid to block the upcoming start of a court-ordered takeover of healthcare operations in its prisons after the state was found to have provided constitutionally inadequate care to incarcerated people and dragged its feet for over a decade in making required improvements. Justice Elena Kagan denied the state's request Thursday, leaving an outside corrections professional set to take over healthcare management for 25,000 incarcerated people on Oct. 19.
