A federal judge has mandated that the Trump administration must preserve records of Signal group chats related to national security discussions, including messages about military operations in Yemen. The ruling comes amidst an outcry regarding the use of the messaging platform by senior Trump officials, which has raised concerns about transparency and accountability. Various lawsuits have emerged, with claims that Signal has been used to discuss sensitive topics without proper record-keeping. The situation has intensified as Trump publicly criticizes the judge handling the cases, branding them as biased. Moreover, several cabinet members are facing legal challenges tied to the content of these chats.
