Skyler Philippi, a 24-year-old from Tennessee, was arrested for allegedly planning to use a drone laden with explosives to attack a Nashville electric substation. Philippi, who expressed ties to white nationalist groups, detailed his plan to an undercover FBI agent, believing that disrupting the power grid would create chaos. He faces serious charges, including attempted use of a weapon of mass destruction. Attorney General Merrick Garland emphasized the Justice Department's commitment to combating domestic extremism and protecting critical infrastructure.
