A California judge temporarily blocked the Pentagon. The ruling exposes how culture wars threaten tech sector stability.

The Big Picture The feud began when the government aimed to contract with Anthropic directly. Until then, the Defense Department had used Anthropic's Claude for much of 2025 without complaint, according to court documents. The company walked a branding tightrope as a safety-focused AI firm that also won defense contracts.

Judge Rita Lin's 43-page opinion suggests what was really a contract dispute never needed to reach such frenzy. It did because the government disregarded existing dispute processes and fueled the fire with officials' social media posts that would eventually contradict court positions.

“The judge found the government "set out to publicly punish Anthropic for its 'ideology' and 'rhetoric'."”

Why It Matters The case sets boundaries on how much the government can punish a company for not playing ball. Labeling Anthropic a supply chain risk would essentially identify it as a "saboteur" of the government, for which the judge saw insufficient evidence.

Government officials tweeted first, lawyered later. President Trump's Truth Social post on February 27 referenced "Leftwing nutjobs" at Anthropic and directed every federal agency to stop using the company's AI. Defense Secretary Pete Hegseth soon echoed this, saying he'd direct the Pentagon to label Anthropic a supply chain risk.

Doing so necessitates that the secretary take specific actions, which Judge Lin found Hegseth did not complete. Letters sent to congressional committees, for example, said less drastic steps were evaluated and deemed not possible, without providing further details.

The government also said the designation was necessary because Anthropic could implement a "kill switch," but its lawyers later admitted having no evidence of that, the judge wrote. Hegseth's post also stated that "No contractor, supplier, or partner that does business with the United States military may conduct any commercial activity with Anthropic." But the government's own lawyers admitted on Tuesday that the Secretary lacks that power, agreeing with the judge that the statement had "absolutely no legal effect at all."
