A U.S. judge on Thursday ordered President Donald Trump's administration to preserve messages sent on the Signal messaging app discussing attack plans against the Houthis in Yemen that became public after they were inadvertently shared with a journalist.

On Thursday, a federal judge who previously blocked the Trump administration from deporting foreign gang members ordered the preservation of all leaked messages between administration officials containing “attack plans.

Judge James E. Boasberg, whom has already drawn President Trump’s ire, ordered national security agencies to preserve the records of a leaked group Signal chat, reportedly set to auto-delete.
