John Carreyrou is the author of Bad Blood, a book about the rise and fall of healthcare startup Theranos. For year, Theranos and its founder, Elizabeth Holmes, conned investors and customers with the promise of a new blood testing technology. Carreyrou's reporting helped expose fraud at the company. John talks to Preet about how people like General James Mattis got pulled into the Theranos orbit, and his own reporting drama around the story.
Also this week, Preet answers your questions about the secret Omarosa tapes and the dramatic Paul Manfort trial.
