A California federal judge denied the DOJ’s request to pause its appeal of a March ruling blocking the Pentagon from labeling Anthropic a supply-chain risk, saying the DC Circuit case is not controlling and four weeks is enough to compile the administrative record from 16 agencies, leaving a circuit split unresolved.
The Department of Justice asked a Northern California judge to pause its appeal of a March ruling blocking the government’s designation of Anthropic as a supply-chain risk to national security, arguing that awaiting a related ruling from the D.C. Circuit could influence the issues and potentially render the California case unnecessary.
A California federal judge temporarily blocked the Pentagon from labeling Anthropic a national-security supply-chain risk, a win that could preserve roughly $200 million in Pentagon work and partnerships. But the ruling is only a partial victory: the government may still pursue the designation under separate statutes, and a D.C. Circuit panel could rule differently, leaving months or years of legal uncertainty for Anthropic and the broader AI industry as appeals proceed.
A federal judge temporarily blocked the Pentagon from labeling AI firm Anthropic a supply-chain risk, delaying the DoD’s ability to apply the risk tag and highlighting judicial scrutiny of government risk assessments on AI vendors.
A federal judge blocked the Pentagon from designating Anthropic as a 'supply chain risk' and paused President Trump's order to cease federal use of Anthropic's Claude, ruling the moves likely unlawful and a First Amendment retaliation, with a seven‑day stay to allow an appeal.
A federal judge laid out the core issues in Anthropic’s bid to block the Pentagon from labeling it a national-security risk, criticizing government actions as potentially punitive and raising questions about First Amendment rights, due process, and Congressional authority in a case that could reshape AI procurement.
A San Francisco judge questions the Pentagon’s designation of Anthropic as a supply chain risk and its move to bar the company’s Claude AI from military work, saying the actions appear punitive and could undermine the firm. Anthropic argues the designation is unconstitutional and seeks to block it, while the DOJ contends the government must guard national security. The hearing underscores a broader AI governance debate over how the tech should be used in government, with Anthropic maintaining red lines against mass surveillance and autonomous weapons; a ruling is expected soon.
Anthropic says it cannot disable or alter Claude or provide a backdoor during military operations, disputing DoD claims it could sabotage the AI; the dispute centers on supply-chain risk and licensing, with court filings and hearings shaping how Claude may be used by the Pentagon.
The Trump administration, in a California federal court filing, defends the Pentagon’s designation of Anthropic as a national-security supply-chain risk after the AI firm refused to loosen guardrails on Claude. Anthropic is suing to block the blacklist, arguing violations of free speech and due process, while the government says the dispute is about contracts and national security, not speech. The filing suggests Anthropic’s ability to win may hinge on federal contracting implications and national-security concerns, with potential losses for the company and impacted government relationships.
Nearly 150 retired federal and state judges filed an amicus brief backing Anthropic in its lawsuit against the Trump administration’s designation of the company as a 'supply chain risk,' arguing the move could set a dangerous precedent for government influence over private AI firms and threaten Anthropic’s government contracts; a preliminary injunction hearing is scheduled as the dispute with the Pentagon and White House intensifies.
Defense Department CTO Emil Michael said Anthropic’s Claude AI models would pollute the defense supply chain due to baked-in policy preferences, justifying a supply-chain-risk designation that could jeopardize hundreds of millions in contracts. Anthropic has sued the Trump administration to overturn the designation, arguing it is unlawful and harms its business. The designation requires contractors to certify they don’t use Claude; Anthropic has published Claude’s constitution, describing how it shapes the model’s safe and ethical behavior. Despite the blacklist, Claude has been used to support U.S. military operations in Iran, and the DoD says a transition plan is in place to move away from Anthropic, noting the change cannot be done overnight.
The Defense Department has directed senior leaders to purge Anthropic AI products, including Claude, from all DoD systems within 180 days after designating Anthropic a supply‑chain risk, affecting key national security operations such as nuclear weapons, ballistic missile defense and cyber warfare; exemptions are allowed only for mission-critical uses with a detailed risk-mitigation plan. Anthropic has sued the government, and OpenAI has a Pentagon deal.
Anthropic warned that its feud with the Pentagon could cost up to $5 billion in revenue as negotiations over guardrails for AI use stall Pentagon contracts. OpenAI and Google researchers filed an amicus brief supporting Anthropic, arguing the Pentagon’s “supply-chain risk” designation could hurt the broader US AI industry. Anthropic is seeking a temporary court order to continue Pentagon-related work while lawsuits challenge the designation and its First Amendment claims. Some customers have paused talks or demanded escape clauses, but major cloud providers will continue offering Claude without Pentagon ties; a San Francisco hearing could happen soon.
Anthropic filed a lawsuit against the Department of Defense and other federal agencies after the Trump administration designated the company a “supply chain risk” and ordered agencies to stop using its Claude AI. The suit argues the designation and directive are unlawful, infringe First Amendment rights, and threaten hundreds of millions of dollars in contracts, seeking injunctive relief to protect current and future business. The case underscores a broader clash over AI use in government, with Anthropic asserting it can work with the Pentagon while upholding redlines against mass surveillance and autonomous weapons.
Anthropic has filed a federal lawsuit to overturn a Trump-era designation that labels its supply chain as a risk, asking a court to remove the designation and the resulting constraints on its operations.
