Presidents should not be exempted from the same standards of reason and evidence and justification that any other citizen or civil movement should be held to.

Let's put it this way. The United States government has assembled a massive investigation team into me personally, into my work with the journalists, and they still have no idea what documents were provided to the journalist, what they have, what they don't have, because encryption works.

I carefully evaluated every single document I disclosed to ensure that each was legitimately in the public interest. There are all sorts of documents that would have made a big impact that I didn't turn over, because harming people isn't my goal. Transparency is.

I describe myself as an indoor cat, because I'm a computer guy and I always have been.

Look at the reactions of liberal governments to the surveillance revelations during the last years. In the United States, we've got this big debate, but we've got official paralysis - because they're the ones who had their hand caught most deeply in the cookie jar.

When I talk about the polling, I'm talking about the principles. It shows these officials are knowingly attempting to shift public opinion, even though they know what they say is not factual.

If a single Russian source would come forward, he would be in hot water. And in the United States, what I did appearing at that [Vladimir] Putin press conference was not worth the price.
