then-speaker ryan not to brief hillary clinton. so there's ambient, latent concern even before the president was inaugurated about his attention to protecting sensitive sources and methods. it's hard to envision, again not confirming or denying here, a more sensitive source. i also will tell you that as a result of this, it's going to become even harder to collect human intelligence in russia. it always has been going back to soviet union days because of the oppressive surveillance. if the asset in question, as has been characterized, this is not something you're going to replace overnight in a week or a month or even years. it takes years to recruit and develop a source like this. again, i'm not confirming or denying anything. >> mm-hmm. i want to move on now.
