- Microsoft and a coalition of 22 retired high-ranking U.S. military officials are challenging the Trump administration's designation of AI firm Anthropic as a supply chain risk.
- The designation, enacted by Defense Secretary Pete Hegseth, blocks Anthropic from securing military contracts, with challengers arguing it constitutes a misuse of government authority and retribution.
- The dispute originated from Anthropic's refusal to permit unrestricted military use of its AI model, Claude, citing ethical red lines against domestic mass surveillance or initiating war without human control.
- Microsoft, a significant government contractor, contends that the Pentagon's action forces contractors to comply with vague directives and could lead to severe economic consequences not in the public interest.
- U.S. District Judge Rita Lin is overseeing the case in San Francisco, with a hearing scheduled for March 24, while military officials are reportedly considering shifting work to Anthropic's competitors.
