and we are back with luke harding, anne applebaum and bill browder talking about russia. luke, you studied russian intelligence carefully and its methods. i want to ask you, what do you make of this report that cambridge analytical, the firm that did extensive work for the trump campaign, really helped the trump campaign figure out where to try to bring out voters and where to suppress voters, and the russians had some contacts which had been previously denied by both sides. the contacts were through a rig russian oil company. is that a direct tie to the kremlin? is it possible this is something unrelated. when you read that story, what did you make of it? >> i was deeply disturbed. it was an astonishing investigation by "the observer"
