A retired Army officer who worked as a civilian for the Air Force has pleaded guilty to conspiring to transmit classified information about Russia's war with Ukraine on a foreign online dating platform. David Slater, 64, who had top secret clearance at his job at the U.S. Strategic Command at Offutt Air Force Base in Nebraska, pleaded guilty to a single count before a federal magistrate judge in Omaha on Thursday. In exchange for his guilty plea, two other counts were dropped.
