House panel advances bill giving Congress veto over AI chip exports

A House Foreign Affairs Committee approved legislation that would give Congress formal review and veto authority over export licenses for advanced artificial intelligence processors bound for China and other designated adversaries. The bipartisan measure, called the AI Overwatch Act and authored by committee Chair Rep. Brian Mast (R-Fla.), moved out of committee on a 42-2-1 vote on Jan. 21, 2026.

The bill would require the Commerce Department to subject exports, re-exports and in-country transfers of certain high-powered AI chips to a licensing regime. It sets two power-based thresholds: a lower threshold at which a license would be required and a higher threshold beyond which exports to listed countries of concern would be prohibited. The measure identifies China, Russia, Iran, North Korea, Cuba and Venezuela as countries of concern.

Under the proposed law, congressional committees would have a formal 30-day review window to examine license applications for covered chips destined for those countries. During that period the House Foreign Affairs Committee and the Senate Banking Committee could seek to block a license by passing a joint resolution, creating a statutory veto mechanism modeled on existing oversight of foreign arms sales. Commerce would also be required to provide lawmakers with detailed license applications and certifications demonstrating that the processors would not be used for military, intelligence or surveillance purposes.

Mast framed the bill as a response to accelerating technology and national security risks, saying the legislation would “ensure congressional oversight keeps pace with advancing technology.” During the committee markup he likened the proposal to existing review of weapons transfers: “If we are selling another country anything that could give them an advantage on the battlefield, it requires congressional notification,” he said.

The markup came after controversy over recent shipments of Nvidia H200 processors to China, and after a widely noted social-media post from President Donald Trump that highlighted economic benefits from sales. The White House’s AI adviser publicly argued against portions of the bill, part of a political backdrop that committee members said helped focus attention on export policy.

Committee consideration also turned on partisan lines for at least one amendment. Rep. Gabe Amo (D-R.I.) proposed adding a “sense of Congress” provision emphasizing the national security risk of H200 sales; the amendment was rejected along party lines. Chairman Mast argued the change would “disregard” the national security conditions the bill itself seeks to enforce.

The committee recorded two dissenting votes from Reps. Andy Barr (R-Ky.) and Rich McCormick (R-Ga.), while Rep. Darrell Issa (R-Calif.) voted present and warned the measure risked turning Congress into a regulator, saying, “Let me assure you, Congress is not a good regulator.”

On the same day, the panel unanimously approved a separate measure to commission a periodic report on China’s AI capabilities, sponsored by Del. James C. Moylan (R-Guam). Committee materials show Mast introduced the AI Overwatch Act in December 2025 and previewed the bill during a Jan. 14 hearing on U.S.-China AI competition.

The legislation now faces floor consideration in the full House and must clear the Senate before it can become law. If enacted, it would alter the current export-control process by embedding a statutory congressional review and potential veto for the most powerful AI processors destined for U.S.-listed adversaries, with the Commerce Department and Senate Banking Committee positioned as primary operational actors under the new regime.
