President Obama’s call to close Guantanamo by next January is in doubt after an administration task force failed to meet today’s deadline to issue a report outlining a long-term detention plan for prisoners captured after Sept. 11. The task force said it would need another six months to complete its report. Newsweek reports the panel has agreed that the Obama administration should continue to claim the right to hold some Guantánamo prisoners indefinitely without charging them either in criminal courts or in military commissions.
