thanks very much for joining us. thank you. what s your biggest concern as an expert on russia? well, i think there are two things that are general areas of concern. we know from the assessment of our intelligence community and other open source information that vladmir putin order add an interview into the u.s. 2016 election. the american voters deserve to know what worked, what didn t work so they can be educated and understand how vladmir putin tried to manipulate their votes and whether a spy sitting in moscow had more impact on the election than a woman voting in iowa. that s a fact finding issue to do with security. the second is the question of collusion and cooperation, criminal activity that might have been helping vladmir putin achieve his objectives in taking down hillary clinton and elevating donald trump. i think that s a separate, also significant set of questions. do you believe there was?
