intellige intelligence committee at the senate. he mentioned putin appears to have a neuro physiological health issues when talking to jake tapper today. this is actually a really, really crucial thing because it lends itself to when you are in sort of deterrence things, it doesn't mean this necessarily when you are deal being a person bhos mentally unstable. does the united states have any sort of assessment that is -- that is accurate on putin's mental health that you are aware of? >> i think it's very difficult to make that type of diagnosis just from watching someone on tv. i think what is clearer is that putin has been surrounded by yes-men. he has been being told what he wants to hear for a very long time. look, i was in ukraine last august and there was a time, prior to 2014, where there were very mixed feelings in ukraine about russia. after 2014, ukraine is anti-russia. and only by getting this -- this watered-down information that putin -- so i amg less qualify on the mental health side but it's clear he has been getting bad information for a long time. >> thank you very much, chairman. appreciate your time.
