AI company Anthropic filed suit against several federal agencies and officials after being labelled a supply chain risk to national security last week.

Anthropic has sued the Defense Department and other federal agencies after the Pentagon announced last week it would label the leading AI company as a threat to national security and ban the use of its products for defense purposes. In late February, Donald Trump said he would also ban the use of Anthropic’s products across other federal agencies.

In its filing, Anthropic alleged that the federal government’s moves to ban Anthropic go beyond a normal contract dispute and instead represent an “unlawful campaign of retaliation.” The company said its “reputation and core First Amendment freedoms are under attack” given the government’s actions and sought to prevent the Trump administration from implementing the bans.

Anthropic said the supply chain-risk designation and messaging from the White House was already “jeopardizing hundreds of millions of dollars,” illegally ignored required procedures and overstepped presidential authority.
