Chief Judge James Boasberg, who has been criticized by President Trump for his involvement in a deportation case, will preside over a lawsuit regarding the administration's use of a messaging app to discuss military operations. The case involves senior national security officials discussing the planned bombing of Houthi targets in Yemen in a Signal group chat. The White House denies that the discussions were classified. Boasberg, who recently imposed a temporary restraining order on the deportation case, has faced criticism from Trump, who called him a "Radical Left Lunatic of a Judge." The lawsuit, brought by American Oversight, alleges that the use of Signal violates federal law on government records preservation.
