Senator Tom Cotton has asked the Justice Department to investigate whether Chinese entities are exerting improper influence on America's artificial intelligence infrastructure. The Arkansas Republican sent a letter urging federal prosecutors to look into potential infiltration, technology transfers, and data security risks tied to Chinese-backed firms operating in the AI space.
What Cotton is asking for
The senator's request is not a formal referral – it's a push for the Justice Department to open a probe on its own. Cotton specifically wants the DOJ to examine whether Chinese companies or state-backed actors are using investments, partnerships, or personnel placement to gain access to U.S. AI systems and the data those systems rely on. He argues that AI infrastructure – from cloud computing to data centers to the models themselves – has become a national security priority and that Washington needs to act before vulnerabilities deepen.
Why AI infrastructure is the focus
Cotton's letter lands as lawmakers in both parties increasingly view artificial intelligence as a strategic asset. The military, intelligence agencies, and critical industries depend on AI tools for everything from logistics to threat detection. Allowing foreign governments – especially a rival like China – to weave themselves into the supply chain or the underlying software could create backdoors or dependencies. Cotton has been one of the most vocal hawks on China in the Senate, and his latest move widens his focus from traditional semiconductor restrictions to the broader AI ecosystem.
The letter's immediate impact
The Justice Department has not publicly responded to the request. The department typically does not confirm or deny whether it is considering an investigation based on a congressional letter. Cotton's office said the letter was delivered late last week. It is now up to federal prosecutors to decide whether the facts merit a formal inquiry. No specific companies or incidents were named in the senator's public statement, though his office indicated the letter references publicly reported concerns about Chinese-linked venture capital investments in U.S. AI startups and the movement of technical personnel between countries.
The move follows broader efforts in Congress to tighten oversight of foreign investments in sensitive technology. A new interagency committee has begun reviewing deals involving AI, but Cotton wants a criminal or counterintelligence investigation on top of that review process. He argues that voluntary disclosures and export controls alone may not catch covert influence campaigns.
