Artificial intelligence company Anthropic is asking a federal judge on Tuesday to temporarily halt the Pentagon’s “unprecedented and stigmatizing” designation of the company as a supply chain risk. A hearing scheduled for Tuesday in a California federal court marks a critical step in the feud between Anthropic and the Trump administration over how the company’s AI technology could be used in war. Anthropic sued earlier this month to stop the Trump administration from enforcing what the company calls an “unlawful campaign of retaliation” over its refusal to allow unrestricted military use of its technology.
