White House Pressures Hagel to Speed Up Release of Terrorist Detainees

U.S. National Security Adviser Susan Rice is pressuring Defense Secretary Chuck Hagel to “step up his pace” in releasing what the White House calls “low level” detainees at the U.S. Naval facility that houses suspected terrorist detainees at Guantánamo Bay, Cuba. The New York Times reports that Rice herself is under pressure from senior White House officials who want her to speed up the release of terrorist detainees.
