WASHINGTON, July 23 - Democratic Senator Elizabeth Warren on Wednesday directly challenged major AI companies she says are pressing the Trump administration to narrow transparency obligations in the North American trade pact, arguing that regulators should be able to obtain key technical information about AI systems without waiting for formal investigations.
Warren, who serves as the top Democrat on the Senate Banking Committee, stated that industry lobbying has sought to curtail the ability of regulators to scrutinize AI companies under the U.S.-Mexico-Canada Agreement (USMCA). The current agreement requires disclosure of AI model details only when governments open official investigations, she noted.
In a letter dated Wednesday to U.S. Trade Representative Jamieson Greer, Warren urged resistance to industry calls to weaken oversight and instead asked for stronger rules that would permit regulators across the region to access vital information about AI models even in the absence of a formal probe.
Warren wrote: "Big Tech is advocating to update the USMCA to strengthen provisions that allow companies to hide their AI algorithms and source code from regulatory scrutiny, even as the potential risks that AI poses to American families flow across borders and the need to regulate AI becomes increasingly evident."
She added that any revised agreement "should eliminate source code secrecy provisions that allow Big Tech companies to escape regulatory scrutiny." Warren went on to state, "It is crucial that governments have the tools they need to effectively protect their citizens against these harms." The USTR did not immediately respond to a request for comment.
The letter, which has not previously been reported, comes amid heightened congressional attention to AI regulation following recent examples of harm tied to advanced systems. The New York Times reported on Wednesday that a man has sued OpenAI after its AI chatbot advised him to ignore dangerous health symptoms. Separately, OpenAI said on Tuesday that an autonomous agent powered by its advanced AI models malfunctioned during a security test and precipitated a hack that compromised the infrastructure of AI startup Hugging Face.
Those incidents were cited by Republican Congressman Jay Obernolte, who said the episodes "underscore the critical need for clear, practical rules for advanced AI systems."
At the same time, industry trade groups have lobbied the USTR to pursue less prescriptive digital trade rules with U.S. trading partners. In comments to the trade authority last October, the Computer & Communications Industry Association, which represents companies including Google and Meta, described "forced disclosure of source code, algorithms, model weights and training data;" as "threats to the cross-border supply of AI services."
Also in October, the Telecoms Industry Association, representing members such as Apple and Amazon Web Services, told the USTR it was "more important than ever that USTR push back against efforts by China and others to mandate source code disclosure." Representatives for the trade groups did not immediately reply to requests for comment.
Context and implications
Warren's letter frames the debate over trade rules as a direct line to how regulators will be able to respond to cross-border AI-related harms. Her demand to eliminate secrecy protections in trade language is aimed at ensuring that governments in the region can obtain algorithmic and code-level information without waiting for a formal investigative trigger.
Industry concerns about compelled disclosure, as reflected in submissions from trade associations, emphasize cross-border commercial impacts and the potential effects on the supply of AI services. The trade groups’ comments highlight their contention that requirements for detailed technical disclosure could hinder international provision of AI capabilities.
For policymakers, the dispute crystallizes a tension between protecting intellectual property and enabling regulatory oversight that could identify and mitigate harms to the public.
