U.S. Senator Warren Writes to Secretary of Defense and Altman: Labeling Anthropic as a "Supply Chain Risk" Appears to Be Political Retaliation, Requests Full Disclosure of OpenAI Contract

According to 1M AI News monitoring, U.S. Senator Elizabeth Warren wrote to Secretary of Defense Pete Hegseth, stating that the Department of Defense's decision to classify Anthropic as a "supply chain risk" seems to be "retaliatory." Warren pointed out that the Department of Defense could have chosen to terminate the contract or continue using Anthropic technology in non-sensitive systems, but instead opted for a more stringent supply chain risk label.

On the same day, Warren wrote to OpenAI CEO Sam Altman, requesting specific terms of the agreement with the Department of Defense. She wrote, "I am particularly concerned that the Department of Defense is attempting to compel American companies to provide tools for monitoring American citizens and deploying inadequately safeguarded fully autonomous weapons." She noted that without seeing the full contract, she could not assess any security terms that may be present, and neither the Department of Defense nor OpenAI have released the full contract.

Hours after Anthropic was blacklisted, OpenAI announced an agreement with the Department of Defense. Anthropic has filed a lawsuit against the Trump administration, with a preliminary hearing scheduled for this Tuesday in the San Francisco federal court. Several technology companies (including OpenAI, Google, Microsoft) and legal advocacy organizations have submitted amicus briefs supporting Anthropic.
