President Barack Obama fought Thursday to retake command of the emotional debate over closing Guantanamo, denouncing "fear-mongering" by political opponents and insisting that maximum-security prisons in the U.S. can safely house dangerous terror suspects transferred from Cuba. In a unique bit of Washington theater, former Vice President Dick Cheney delivered his own address just one minute later, defending the Bush administration's creation of the prison camp as vigorously as Obama denounced it.
