AI Summary

# Summary A California judge temporarily blocked the Pentagon from designating AI company Anthropic as a supply chain risk, finding the government's actions likely violated the company's First Amendment rights and contractual protections. Judge Rita Lin's 43-page opinion criticized senior officials—including President Trump and Defense Secretary Pete Hegseth—for using social media to publicly attack Anthropic's ideology before following proper legal procedures, undermining the government's case that the designation was necessary for national security. The judge found that the government provided no evidence for its claim that Anthropic could implement a "kill switch" and that Hegseth lacked legal authority to enforce the restrictions he announced. The government has seven days to appeal, and Anthropic has a separate case pending in Washington D.C. on the same issue, while the Pentagon previously used Claude without complaint until direct contracting negotiations began.

What's Being Done

Judge Rita Lin issued temporary block; government has seven days to appeal; separate D.C. case pending on same issue.
