senator chris murphy, is a member of the foreign relations committee. as i mentioned a moment ago, we have not got confirmation on this, but we are seeing reports from other reporters, and other agencies in kyiv, that say there are some loud explosions tonight with, the context of that is that there has been discussions in istanbul about pulling back, about the russians pulling back from kyiv in favor of just sort of taking eastern ukraine, that they are looking for. i think we might have senator murphy back. senator, are you back with us? >> i got you know. >> excellent, you're a tv pro, because even you knew we were having technical difficulties, when you can hear me. when asked about the proposal that some of the ukrainians have made, and that is that if they can't join nato, can there be a mechanism set up by which their territorial integrity is protected, and that others will come to their defense if russia tries this nonsense again?
