One journalist said that everybody in Russia is miserable. Russia is a terrible place. And I'm going to end up miserable and I'm going to be a drunk and I'm never going to do anything. I don't drink. I've never been drunk in my life. And they talk about Russia like it's the worst place on earth. Russia's great.

We have got a CIA station just up the road – the consulate here in Hong Kong – and I am sure they are going to be busy for the next week. And that is a concern I will live with for the rest of my life, however long that happens to be.

All the governments just want to have more power when it comes to economic espionage, diplomatic manipulation and political influence.

We need to think about encryption not as this sort of arcane, black art. It's a basic protection.

We should know at least the broad strokes of the powers that the government's claiming in our name, and using allegedly, on our behalf. And also against us as well.

I don't think it is the most important thing. I think it is the fact that the director of national intelligence gave a false statement to Congress under oath, which is a felony. If we allow our officials to knowingly break the law publicly and face no consequences, we're instituting a culture of immunity, and this is what I think historically will actually be considered the biggest disappointment of the [Barack] Obama administration.

You are also asked to take an oath, and that's the oath of service. The oath of service is not to secrecy, but to the Constitution - to protect it against all enemies, foreign and domestic. That's the oath that I kept, that James Clapper and former NSA director Keith Alexander did not. You raise your hand and you take the oath in your class when you are on board. All government officials are made to do it who work for the intelligence agencies - at least, that's where I took the oath.
