it doesn't make sense you call the cia director to give him a heads-up that the president had overstepped in a serious ray in a meeting with senior russian officials, calling the nsa director. those two officials are the ones dealing most directly with this partner. they're the ones that would have to deal with this partner to try to keep this intelligence channel open, to try to protect it and try to contain whatever damage was caused by this disclosure. >> david ignatius, as somebody who covers the intel community and has for a long time, can you explain why this is so troubling, even if it's one nugget that the president let slip to the russian ambassador and foreign minister, why this could be such a problem? >> the intelligence business works on trust and works on the confidence that intelligence partners have, the information they provide, information often obtained through very risky collection methods, will be properly held, that it will not be disseminated at a whim.
