Warren Challenges Pentagon's xAI Access to Classified Networks
Sen. Elizabeth Warren sent a letter to Defense Secretary Pete Hegseth questioning the Pentagon’s decision to grant Elon Musk’s xAI (Grok) access to classified networks, citing reports that Grok has produced dangerous outputs — including advice on committing murders and terrorist attacks, antisemitic content, and child sexual abuse material. Warren requested details of the DoD’s deal with xAI and asked how the department will assess and mitigate national security, cybersecurity and safety risks. The article notes a coalition of nonprofits urged suspension of Grok’s federal deployments and that a class-action lawsuit was filed alleging Grok generated sexual content from real images of minors. The piece also references the Pentagon labeling Anthropic a supply-chain risk after that company resisted unrestricted military access, and states the DoD has agreements with OpenAI and xAI to onboard models to the GenAI.mil platform; Pentagon officials say Grok is onboarded but not yet in use.
Government decisions to grant classified-network access to commercial AI models and congressional scrutiny have broad implications for national-security risk assessment, vendor procurement, industry governance, and standards for AI safety — affecting how governments and large organizations adopt and regulate AI vendors.

Warren Accuses Trump Admin of Pressuring EU on Tech Rules
Sen. Elizabeth Warren sent a letter to U.S. Trade Representative Jamieson Greer accusing the Trump administration of pressuring European countries to relax regulations aimed at holding large tech firms accountable for enabling child sexual exploitation online. Warren alleges the administration threatened tariffs after European investigations were opened into xAI and its Grok image generator, which a report says contributed to the spread of sexually explicit deepfakes. The National Center on Sexual Exploitation named X (owned by xAI) and Grok among top contributors to online sexual exploitation in 2026. Warren is seeking USTR records on communications with Musk-associated businesses and industry lobbyists and criticized exemptions for big tech from some tariffs. The article also notes SpaceX recently acquired xAI, which is expected to file IPO paperwork soon.
Sen. Warren Probes DoD Anthropic Blacklist Decision
Senator Elizabeth Warren sent formal letters to Defense Secretary Pete Hegseth and OpenAI CEO Sam Altman questioning the Department of Defense’s decision to designate Anthropic as a “supply chain risk,” calling the move potentially retaliatory. Warren said the DOD could have terminated or limited its Anthropic contract instead of applying the label and expressed concern the department seeks unfettered access to models for broad "lawful purposes." The article notes Hegseth directed the supply-chain-risk designation on Feb. 27, the DOD continued using Anthropic’s Claude model in Iran, and Anthropic has filed a lawsuit against the Trump administration with a preliminary hearing set in the Northern District of California. OpenAI announced a DOD deal after Anthropic’s blacklisting; Warren requested contract terms to assess safeguards against mass surveillance and autonomous weapons use.
Pentagon Deploys Custom ChatGPT and Grok for Military Use
The U.S. Pentagon has deployed custom military-grade versions of OpenAI's ChatGPT and xAI's Grok, making them available to 3 million military and civilian personnel via its secure GenAI.mil portal. The portal, which launched last year with Google Gemini, allows Department of Defense employees to use commercial frontier AI models without transmitting sensitive government data through public consumer networks. ChatGPT Mil will assist with unclassified administrative tasks, logistics, and planning, while Grok for Government (integrated with SpaceX's Starshield AI) is geared towards enhancing operational precision and supply chain management. Notably, Anthropic's Claude remains excluded due to an ongoing supply-chain dispute with the Trump administration regarding safety guardrails. The Pentagon has also secured AI deployment agreements with other major tech firms, including AWS, Microsoft, Nvidia, and Reflection AI.
