"I think Snowden has done a service ... I wouldn’t have had the courage, and maybe not even the intellectual capacity, to do it the way he did it ... There’s a logic to what he has done that is impressive ... He really has refrained from anything that was truly dangerous, with regard to our security — regardless of what people say. He has been circumspect about what he's released, how he's released it, who he's released it to. It’s clear to me from listening to his personal statements — I think those are important — that he did have a genuinely altruistic motive for doing it."
