Warren presses Pentagon over decision to grant xAI access to classified networks Rebecca Bellan 1:58 PM PDT · March 16, 2026 Sen.
Elizabeth Warren (D-MA) sent a letter to Defense Secretary Pete Hegseth on Monday expressing concern over the Pentagon’s decision to give Elon Musk’s company xAI access to classified networks.
“Grok, the controversial AI model developed by xAI, has provided disturbing outputs for users, including giving users ‘advice on how to commit murders and terrorist attacks,’ generating antisemitic content, and creating child sexual abuse material,” the letter reads.
Warren said Grok’s “apparent lack of adequate guardrails” could pose “serious risks to the safety of U.S.
military personnel and to the cybersecurity of classified systems.” She demanded Hegseth provide information on how the Department of Defense plans to “mitigate these potential national security risks.”
Warren isn’t the first to express alarm at Grok, xAI’s controversial chatbot, gaining access to classified systems.
