Senator Warren Probes DoD AI Contracting Practices
March 24, 2026
Senator Elizabeth Warren has initiated a formal investigation into the U.S. Department of Defense's designation of AI company Anthropic as a national security supply chain risk, a move that effectively blocks Anthropic from defense contracts. This designation follows Anthropic's refusal to remove contractual safeguards limiting military use of its AI models, particularly concerning mass surveillance and autonomous weapons. Concurrently, the DoD has awarded a new contract to OpenAI for AI technology deployment in classified networks, raising concerns about the adequacy of safeguards against misuse. Senator Warren's probe scrutinizes the DoD's contracting approach, emphasizing the balance between national security interests, ethical AI use, and procurement transparency. This development highlights evolving challenges in federal AI procurement, especially regarding ethical constraints and supply chain risk designations.
- Procurement professionals should note the increased scrutiny on AI vendors' contractual terms related to military use and ethical safeguards.
- Contractors may face heightened risk assessments and potential blacklisting based on supply chain risk designations tied to AI ethics and national security.
- Agencies and vendors should prepare for potential policy or procedural changes affecting AI technology acquisitions and contract compliance.
- Transparency in contract terms and safeguards is becoming a critical factor in federal AI procurement, influencing vendor eligibility and contract awards.
DoD did not have to take such extreme actions: it could have chosen to terminate its contract with Anthropic or continued using its technology in unclassified systems. Instead, it appears that you went beyond this approach and retaliated against the company by weaponizing longstanding statutes intended to protect against genuine national security threats.

Ultimately, it is impossible to assess any safeguards and prohibitions that may exist in OpenAI's agreement with DoD without seeing the full contract, which neither DoD nor OpenAI have made available.
