In a town hall last night, President Donald Trump denied familiarity with QAnon, the cult theory that has cast him in a central role in the battle against an international conspiracy. Host Marco Werman speaks with Anna-Sophie Harling, managing director for Newsguard in Europe, about QAnon, the Trump lore, and how it is taking hold in countries well beyond the US. Harling is a co-author of Newsguard's Special Report: QAnon in Europe.
