In a letter to Defense Secretary Pete Hegseth, Senator Elizabeth Warren (D-MA) equated the DOD's decision to label Anthropic a "supply-chain risk" as retaliation, arguing that the Pentagon could simply have terminated its contract with the AI lab.

The Defense Department said concerns that Anthropic might "attempt to disable its technology" during "warfighting operations" validate its decision to label the AI firm a supply-chain risk.

More than 30 OpenAI and Google DeepMind employees signed onto a statement supporting Anthropic's lawsuit against the Defense Department after the agency labeled the AI firm a supply-chain risk, according to court filings.

Anthropic filed suit against the Department of Defense on Monday after the agency labeled it a supply-chain risk. The complaint calls the DOD's actions "unprecedented and unlawful."

Trump's Department of War feud with Anthropic won't impact other companies that are using Claude via Microsoft and Google products.

Anthropic CEO Dario Amodei said he plans to challenge the Department of Defense's designation of the AI firm as a supply-chain risk. He claims most Anthropic customers are unaffected by the label.

The Department of Defense has officially labeled Anthropic a supply-chain risk, making the AI firm the first American company with the label. Meanwhile, the DOD continues to use Anthropic's AI in Iran.

Tech workers have signed an open letter urging the Department of Defense to withdraw its designation of Anthropic as a "supply chain risk" and instead to settle the matter quietly.
