Judge Shuts Down Trump’s Attempt to Blacklist Anthropic: ‘Classic First Amendment Retaliation’

A federal judge just handed the Trump administration a pretty clear loss in its fight against Anthropic. US District Judge Rita Lin didn’t mince words when she described the Department of War’s attempt to blacklist the AI company as “classic First Amendment retaliation.”

Lin granted Anthropic’s request for a preliminary injunction, blocking the Department of War from designating the company as a supply-chain risk. Her order cuts through the usual government jargon and gets straight to the point: this wasn’t about national security, it was about punishing a company that spoke out.

“By all appearances, these measures appear designed to punish Anthropic,” Lin wrote. That’s a remarkable statement from a federal judge, and it suggests the court sees this as a straightforward case of the government using its power to silence critics.

The Department of War’s own records apparently show the real reason for the blacklisting: Anthropic’s “hostile manner through the press.” Not evidence of security risks, not proof of vulnerabilities, just a company being difficult with journalists. That’s a flimsy basis for designating anyone a supply-chain risk, let alone a major AI company.

Lin also pointed out that officials didn’t bother considering less restrictive alternatives or providing any evidence that Anthropic posed an urgent threat to national security. They just went straight for the nuclear option, which makes the whole thing look even more retaliatory.

I’ve seen this pattern before in tech policy disputes. When a company criticizes the government, suddenly there are “security concerns” that nobody can quite explain. The legal standard for supply-chain risk designations isn’t supposed to be “we don’t like their tone,” but that’s essentially what the Department of War was running on here.

The injunction means Anthropic can continue operating without the blacklisting cloud hanging over it, at least for now. The case will proceed, but this preliminary ruling doesn’t bode well for the government’s position.

What’s striking is how transparent the retaliation appears to be. The Department of War didn’t even bother creating a paper trail that would hold up to scrutiny. Their own records contradicted their stated justification. That’s either incredible incompetence or a sign that they thought they could push this through without anyone checking the details.

Either way, the judge saw through it. And that’s a good reminder that even in an administration that’s pushed the boundaries of executive power, the courts can still slam the brakes when the government gets too creative with its national security authority.
