Outgoing Defense Secretary Chuck Hagel acknowledged Friday for the first time that some officials in the White House disagreed with his slow pace in releasing Guantanamo detainees. He explained he was cautious because he took "very seriously" his responsibility to certify the release of detainees to ensure they did not return to the battlefield.
"Not everyone at the White House has agreed with how I’ve handled some of this,” Hagel told CNN in an interview aired Friday.
“I have made it very clear that I will not certify -- sign anything -- to release a detainee as long as I’m secretary of Defense unless I am convinced that it is in the best interest of this country. And a substantial mitigation of risk can be verified, as closely as we can verify it.”
