06:48

Andrea Mitchell and her panel discuss the latest on the Mueller report and revisit Russian involvement in U.S. politics. On the panel is Angela Stent, director for Eurasian, Russian, and East European Studies at Georgetown University. "I think we were asleep at the wheel in 2016, we know that the Russians interfered both on the cybersphere and also on social media ... We really have to be very concerned about this," Stent says.
