A federal judge has directed the Trump administration to preserve Signal messages exchanged by national security officials regarding military operations in Yemen, following revelations regarding the sharing of potentially classified information. The order, issued by U.S. District Judge James Boasberg, covers messages sent between March 11-15 and is part of a lawsuit by American Oversight, which claims the use of Signal violated federal record-keeping laws. The discussions included sensitive details about an imminent military strike on Houthi rebels. The ruling underscores concerns about accountability and retention of government communications.
