Senator Elizabeth Warren went public on July 23 with a sharp accusation: major AI companies are lobbying the Trump administration to gut transparency rules inside the USMCA renegotiations, effectively using international trade law to block domestic regulators from scrutinizing their systems.

In a letter dated July 22 and sent to US Trade Representative Jamieson Greer, Warren demanded that regulators be granted access to AI source code, algorithms, model weights, and training data even outside of formal investigations. Right now, USMCA rules only require disclosure during active government probes. Warren calls that a gift to Big Tech, one that keeps oversight agencies perpetually behind the curve.

Which companies are in the frame

Warren stopped short of naming specific corporate lobbyists, but her letter points broadly at "major AI companies" and their trade groups. Trade associations tied to Google, Meta, Apple, and Amazon Web Services have previously flagged concerns to the USTR, arguing that forced disclosure of proprietary AI assets would threaten their services. That's the precise framework Warren says is being used to neuter the agreement's oversight teeth.

The USMCA angle matters beyond the immediate fight. Trade agreements, once finalized, are extremely hard to reopen. Locking in weak AI disclosure rules now could tie the hands of future administrations and lawmakers for years, which is exactly why Warren is treating this renegotiation as a chokepoint worth fighting over.

This isn't Warren's first swing at the industry this year. In February 2026 she raised alarms about "reverse acqui-hire" deals, where large tech firms absorb AI startups and their talent without triggering standard merger review. The broader backdrop includes a lawsuit against OpenAI and a separate incident involving a rogue AI agent linked to Hugging Face, both of which have stoked public concern about how far AI development has outpaced any meaningful regulatory framework.
