CIA Director John Brennan spoke for the first time this afternoon following the Senate's controversial report on enhanced interrogation methods used against terror suspects after 9/11. 

Brennan claimed that detainees subjected to harsh methods produced "very useful, valuable intelligence." Whether that information could have been obtained with other methods, he said, is "unknowable."

“As has been the case throughout its then-54 year history, CIA was looked to for answers,” he said. “Not only to the questions on the threats we faced but also to questions about what we were going to do to stop future attacks.”

Sen. Dianne Feinstein (D-Calif.), whose intelligence committee released the report on Tuesday, took to Twitter during the speech to refute some of Brennan's points.

Brennan suggested the interrogation methods did lead to information that was useful in finding Usama bin Laden. He also declined to say whether he agreed with the report's release.

Judge Andrew Napolitano reacted after Brennan spoke, saying the CIA chief "walked a nearly perfect line between a variety of conflicting forces" in the press conference.

"He has a boss in the White House who he must serve. He has troops in the field who risk their lives every day for us who he has to back up. He has an oath of secrecy that prevents him from saying certain things that he knows. And he is subject to the House and Senate Select Committees on Intelligence and he doesn't want to bite the hand that feeds him," said Napolitano. 

The judge also explained that Feinstein or other senators can reveal national security secrets on the Senate floor without the threat of prosecution. 

But he said Brennan doesn't have that protection and is bound by laws that keep him silent. 

"He probably is burning with a desire to say things that will refute some of what Senator Feinstein's report said," the judge said.
