Country's Top Spy-Catcher Bill Evanina on Espionage Threats

In this episode of Intelligence Matters, host Michael Morell speaks with William Evanina, Director of the National Counterintelligence and Security Center, about the top counterintelligence threats facing the United States. Evanina shares his experience tracking the operational activities of Russian agents in the so-called "illegals" network that culminated in a U.S.-Russia prisoner exchange in 2010. He explains how Russia's ongoing tactical efforts today target critical infrastructure and elections systems, and details the risks posed by non-traditional collection efforts by China. He also tells Morell what other countries are on his "worry list" of increasingly sophisticated espionage challenges.
