DHS orders DeepSeek products removed from civilian federal agencies

DHS has ordered civilian federal agencies to stop buying DeepSeek products and remove them, including third-party products built on DeepSeek, citing the Federal Acquisition Supply Chain Security Act. The signed letter is dated June 26; the notice publishes Oct. 20. Exception requests need 60 days' notice. Secretary Mullin cites data stored in China. CyberScoop reports no response from DeepSeek or Beijing. About 25 outlets cover it.
