Warren Presses Hegseth on xAI Grok Access to Classified Networks; Demands Safeguard Details by March 30

Sen. Warren sent a letter to SecDef Hegseth demanding the full xAI-Pentagon agreement, all communications, and safeguard documentation by March 30. Warren cited Grok's documented generation of harmful content including terrorism advice and CSAM as evidence of inadequate guardrails for classified deployment. The letter follows Anthropic's supply chain risk designation after refusing unrestricted Pentagon access, implying security standards are being selectively applied.
