The Department of Defense's acting Inspector General (IG) is investigating Secretary of Defense Pete Hegseth's use of the encrypted messaging app Signal to discuss military strikes against the Houthis in Yemen. The investigation, prompted by a report in The Atlantic, will examine whether Hegseth and other officials complied with DoD policies and procedures for using commercial messaging applications for official business, and whether classified information was shared.
The Atlantic's report indicated that Hegseth shared highly classified information, including the timing of strikes and the types of weapons used, 30 minutes before the operation began. However, Hegseth’s spokesperson maintains that no classified information was exchanged.
