President Barack Obama pledged Tuesday to renew his efforts to close the Guantanamo Bay terrorist detention center, where 100 out of 166 detainees are in a weeks-long hunger strike. "I think all of us should reflect on why exactly are we doing this," Obama said, referring to the detentions. "Why are we doing this?" The president — who signed an executive order requiring the closing of the prison at the start of his presidency — said he didn't want "these individuals to die" and that the Pentagon was trying to manage the situation in the best way possible. Though many members of the president's party support his decision, opposition in Congress has prevented him from shuttering the detention center. Obama has called the facilities "expensive," "inefficient" and hurtful in terms of U.S. "international standing."
