John Williams, a wilderness survival trainer, spent two years undercover moving up through the ranks of two militias, the Oath Keepers and American Patriots Three Percent, gathering a vast trove of information about one of the most dangerous movements in America. He didn’t inform authorities and said nothing to his family and friends. The one person he told was ProPublica reporter Joshua Kaplan. He feared someone was in danger and tried to warn them, but it backfired. Williams was sure at least one person knew he was a double agent, so he fled and sent ProPublica a thumb drive with more than 100 gigs of documents, audio, chat logs and video. This is what we found. 📰: Joshua Kaplan 🎨: Katherine Lam for ProPublica 🎥: josesepulvedatv #jan6th #capitolriot #militia #ap3 #oathkeepers
