On March 23, 2026, Senator Elizabeth Warren sent letters to Defense Department officials, including Pete Hegseth and Sam Altman, seeking more information about OpenAI's defense contract.
Warren's inquiry highlights concerns regarding the potential blacklisting of Anthropic, which may be perceived as a retaliatory action linked to OpenAI's contract.
This situation raises important questions about the implications for defense contracting and the operational landscape for AI companies involved in government projects.
