This is the full text of the panel at the Aspen Security Conference 2016 in which the Director Clapper admitted that the US Intel community is at war with Russia:

MR. SCIUTTO: So, let’s turn that around, if Putin sees himself as fighting this sort of low level war, in your job do you look at yourself as at war to some degree with Russia?
MR. CLAPPER: Well, that’s the nature of the intelligence business. I guess if you want to put it in that context, I guess we are at war and we are doing an operational mission 7/24 365 against a number of known adversaries or potential adversaries. So, I guess in a sense that’s our version of war.
