In this episode of Intelligence Matters, host Michael Morell speaks with David Shimer, author of Rigged: America, Russia and 100 Years of Covert Electoral Interference. Shimer provides examples of Russian and American electoral interference in countries around the world over nearly a century. He explains how Russia's playbook has been applied repeatedly and in novel ways to influence American democratic processes -- including in 2016. Morell and Shimer discuss ways the U.S. should seek to bolster its defenses against new potential Russian incursions in 2020.
