The U.S. Supreme Court on Monday declined to hear the Trump administration's appeal of a federal judge's ruling that requires the government to keep the Deferred Action for Childhood Arrivals program going. Under a lower court order that remains in effect, the Department of Homeland Security must continue to accept renewal applications from the roughly 700,000 young people who are currently enrolled in the program, known as DACA. The administration had intended to shut the program down by March 5, but that deadline is now largely meaningless.
