Warren presses Pentagon over decision to grant xAI access to classified networks

Sen. Elizabeth Warren sent a letter to Defense Secretary Pete Hegseth raising concerns about the Pentagon granting Elon Musk's xAI access to classified networks, citing Grok's history of generating harmful content including advice on violence and child sexual abuse material. The move follows the Pentagon labeling Anthropic a supply chain risk after it refused unrestricted military access, while signing agreements with OpenAI and xAI for classified network use. A senior Pentagon official confirmed Grok has been onboarded for classified use but is not yet active.
