Guest-hosted by Brian Stelter: Between the upcoming presidential election, rapidly improving artificial intelligence, and weakened social-media safeguards, disinformation is becoming an increasingly urgent issue in the U.S. In her new book, Attack From Within: How Disinformation Is Sabotaging America, legal analyst and former U.S. attorney Barbara McQuade argues that American democracy will suffer if we don’t distinguish truth from lies. McQuade spoke with Apple News In Conversation guest host Brian Stelter about America’s disinformation problem and how to address it.
