"The President's decision to move forward with the transfer of these detainees was a tough call," Hagel said. I supported it. I stand by it. As Secretary of Defense, I have the authority and the responsiblity, as has been noted here, to determine whether detainees ... at Guantánamo Bay can be transfered to the custody of another country. I take that responsiblity, Mr. Chairman, members of this committee, damn seriously. Damn seriously. As I do any responsibility I have in this job."
