Retired lieutenant colonel shared SECRET-level briefings from U.S. Strategic Command to a purported “Ukrainian woman,” exposing targets and Russian capabilities, prosecutors say
LINCOLN, Neb. | A retired U.S. Army lieutenant colonel who later worked as a civilian at U.S. Strategic Command has been sentenced to 70 months in federal prison for conspiring to transmit classified national-defense information about the Russia-Ukraine war via a foreign online dating platform. David Franklin Slater, 64, also received a $25,000 fine and one year of supervised release; he pleaded guilty in July after his March 2024 arrest, and two additional counts were dismissed under the plea deal.
According to court filings, Slater held a Top Secret clearance while assigned as an Air Force civilian at Offutt Air Force Base, Nebraska (U.S. Strategic Command) between August 2021 and April 2022, where he attended classified briefings on the conflict. He admitted he conspired to transmit SECRET information about military targets and Russian capabilities to a person he believed was a woman in Ukraine, communicating through the site’s messaging tools.
Messages from the unnamed coconspirator included endearments—calling Slater “my secret informant love!” and “my secret agent. With love.”—and prodded for details such as whether “NATO will prepare a very pleasant surprise” for Russia. Prosecutors have not publicly identified the coconspirator or confirmed any government affiliation.
FBI Omaha Special Agent in Charge Eugene Kowel said Slater “betrayed an oath” and “put our country at risk,” while the U.S. Attorney’s Office for the District of Nebraska emphasized the breach of the trust placed in cleared personnel. The sentence—70 months—falls within the range contemplated at the plea, which anticipated roughly 5 years 10 months to 7 years 3 months.
