We don't have sources who are dissidents on other sources. Should they come forward, that would be a tricky situation for us, but we're presumably acting in such a way that people feel morally compelled to continue our mission, not to screw it up.

We have a way of dealing with information that has sort of personal - personally identifying information in it. But there are legitimate secrets - you know, your records with your doctor; that's a legitimate secret.

Facebook in particular is the most appalling spying machine that has ever been invented. Here we have the world's most comprehensive database about people, their relationships, their names, their addresses, their locations and the communications with each other, their relatives, all sitting within the United States, all accessible to US intelligence. Facebook, Google, Yahoo.. all these major US organizations have built-in interfaces for US intelligence. It's not a matter of serving a subpoena. They have an interface that they have developed for US intelligence to use.

Hillary Clinton represents a whole network of people and a network of relationships with particular states.
