Judge Shuts Down Trump’s Attempt to Blacklist Anthropic, Calls It ‘Classic First Amendment Retaliation’

Remember when the Trump administration tried to blacklist Anthropic, the AI safety company behind Claude? Turns out, a federal judge wasn’t having any of it.

US District Judge Rita Lin just granted Anthropic a preliminary injunction against the Department of War, and her ruling is a brutal takedown of what she called “classic First Amendment retaliation.”

Here’s the short version: The Department of War wanted to designate Anthropic a “supply-chain risk” — a label that effectively blacklists a company from federal contracts and partnerships. Their reasoning? Anthropic had the audacity to criticize the administration in public.

Lin wasn’t buying it. “By all appearances, these measures appear designed to punish Anthropic,” she wrote. That’s about as damning as it gets for a government agency trying to justify a blacklist.

What really got me was the detail about how the Department of War’s own records showed they targeted Anthropic because of its “hostile manner through the press.” Not because of any actual national security threat. Not because of evidence of wrongdoing. But because the company said things the administration didn’t like.

This is higher than I expected — the judge didn’t just find procedural problems. She found a pattern of retaliation that strikes at the core of the First Amendment.

Lin also pointed out that officials seemed to have no authority to take such extreme actions without considering less restrictive alternatives. No evidence was offered that Anthropic posed any urgent risk to national security. It was just punishment, plain and simple.

For those keeping score at home, this isn’t the first time a court has pushed back against executive overreach in tech. But it’s notable because Anthropic isn’t some fly-by-night startup. They’re one of the leading AI safety companies, and they’ve been vocal about government AI policy — including criticism of the previous administration’s approach.

The ruling is a reminder that even when the executive branch wants to punish a company for speaking out, there are limits. The First Amendment still means something, even when the target is a corporation.

I suspect this case will have ripple effects beyond just Anthropic. If the government can’t blacklist a company for being rude in the press, that sets a precedent that protects any tech company that dares to criticize policy. And given how polarized the AI policy debate has become, that’s a meaningful safeguard.

For now, Anthropic can breathe easy. But the administration will likely appeal, and this could drag on for months or years. The bigger question is whether the next administration — regardless of party — will try similar tactics.

Because if there’s one thing we’ve learned from the past few years, it’s that the tools of retaliation don’t disappear when the party in power changes. They just get pointed at different targets.
