The Militia and the Mole: Reporter Josh Kaplan on How a Freelance Vigilante Infiltrated U.S. Militias

We speak with Pulitzer Prize-winning reporter Joshua Kaplan about his latest blockbuster article for ProPublica chronicling the rise of a “freelance vigilante” through the ranks of the right-wing militia movement in an effort to surveil and disrupt their operations. Kaplan’s source, a wilderness survival trainer named John Williams, says he went undercover after being shocked by the January 6 insurrection, when members of the Proud Boys, Oath Keepers and other armed right-wing groups led the riot at the U.S. Capitol. “He’s an extraordinarily talented liar,” Kaplan says of Williams. “These militia guys loved him.” Williams would eventually gain the trust of senior leaders in Utah and beyond, collecting information that revealed a sprawling extremist movement with connections to law enforcement, lawmakers and more. Kaplan says Williams’s infiltration revealed the militia movement is surging across the country, despite the failed 2021 insurrection. Now with Donald Trump promising to pardon many of the Capitol riot participants, this same movement appears set to expand even further over the next few years. “The ramifications could be massive,” says Kaplan. “They have the potential to trigger a renaissance for militant extremists.”
