Anthropic sued the U.S. government, demanding the removal of the blacklist and the restoration of its federal contracts.

CoinFeed reported on March 9 that, according to lawsuit documents, Anthropic is requesting a court order to overturn the U.S. Department of Defense's blacklisting of the company and reinstate its federal contracts. Anthropic argues that the First Amendment to the U.S. Constitution protects the right to set ethical boundaries for one's technology without retaliation. Anthropic sued the U.S. government after being designated a "supply chain risk" company for refusing to remove security barriers.
