US Bars DeepSeek AI From Federal Civilian Agencies; China Pledges Response

The US Department of Homeland Security has ordered all federal civilian agencies to remove and cease procuring DeepSeek AI products and services, invoking national security concerns over data exposure to Chinese authorities. The ban, announced October 20, 2026, applies to the Treasury, State, and Justice departments and extends to any third-party products built on DeepSeek's technology, though it does not affect private businesses or American consumers.
