A federal judge sided with Anthropic in its fight with the Pentagon on Thursday, blocking its designation as a supply chain risk and halting President Trump's order to cut all government contracts with the AI company.
U.S. District Judge Rita Lin, a Biden appointee serving in California, described the administration's actions as "classic" First Amendment retaliation in a 43-page opinion. She paused her ruling from taking effect for a week, giving the Trump administration an opportunity to seek relief from the U.S. Court of Appeals for the 9th Circuit.
What the Left Is Saying
Progressive advocates and civil liberties groups have long raised concerns about government use of AI in military contexts. Senator Mark Warner, a Virginia Democrat who chairs the Senate Intelligence Committee, has previously called for greater transparency around AI contracts. The American Civil Liberties Union has argued that designating an American company as a supply chain risk based on its policy positions sets a dangerous precedent for free expression. Progressives have supported Anthropic's position that companies should not be penalized for refusing to allow their technology to be used in autonomous weapons or mass surveillance of Americans.
What the Right Is Saying
Conservative commentators and some national security hawks have defended the Pentagon's authority to manage its supply chain. Senator Tom Cotton, an Arkansas Republican, has argued that the federal government must have flexibility to ensure national security. The Heritage Foundation has contended that a president's executive authority over procurement decisions is broad and that companies receiving government contracts should not dictate how the military operates. Some conservative voices have suggested that Anthropic's refusal to fully cooperate with Pentagon requests amounts to prioritizing profit over national security.
What the Numbers Show
Judge Lin's ruling does not address the merits of whether Anthropic poses an actual supply chain risk. The Pentagon has designated only a small number of companies — typically foreign-owned — under the supply chain risk designation. Anthropic is the first U.S.-based AI company to receive this classification. The Department of Health and Human Services and the General Services Administration removed Anthropic's products from their agencies following Trump's executive order. The judge's preliminary injunction blocks several sweeping actions, including a ban on Anthropic receiving government contracts and restrictions on contractors doing business with both the military and Anthropic.
The Bottom Line
The temporary injunction represents a significant early victory for Anthropic, but the legal battle is far from over. The Justice Department can seek an emergency order from the 9th Circuit before the injunction takes effect. Judge Lin emphasized she is not preventing the Pentagon from simply choosing a different AI vendor, noting that decision is "the Department of War's prerogative." Anthropic has separately challenged the administration in federal court in Washington, D.C., where another ruling remains pending. The case is likely to become a landmark decision on the intersection of government contracting, First Amendment rights, and national security.
