Congress tightens AI chip export rules

Highlights

Bipartisan support is intensifying for AI chip export curbs following Nvidia founder Jensen Huang's resignation and the investigation into Megaspeed's alleged smuggling to China.
Lawmakers plan to attach several AI chip export restriction bills, including the Remote Access Security Act, to the National Defense Authorization Act for passage before January 2025.
Pressure is mounting on the Commerce Department and Nvidia leadership to explain how U.S. chips reached blacklisted entities, with Congress considering stricter export licensing and oversight.

Legislative push gathers pace on Capitol Hill

As reported by the Financial Times, Democrats and Republicans are accelerating support for a group of bills that would curb sales of sensitive AI chips overseas and give Congress greater authority to review, and potentially block, exports already approved by the Trump administration.

The renewed effort follows revelations involving Nvidia founder Jensen Huang, who resigned earlier this week after reports of extramarital affairs, including with a woman suspected of ties to Chinese intelligence. U.S. authorities have been investigating for more than a year whether Singapore-based Megaspeed, an Nvidia customer, was smuggling chips to China.

One proposal, the Remote Access Security Act, would prevent Chinese companies from remotely accessing advanced chips overseas through cloud services, even when they are barred from purchasing the hardware directly. Three senior House Republicans, John Moolenaar, Brian Mast and Rick Crawford, urged colleagues on Friday to pass several AI chip export bills immediately and requested appearances before Congress by Huang, Nvidia General Counsel Tim Teter and export controls official Jeffrey Kessler.

Supporters of the measures argue that restricting exports is critical because Nvidia chips help train the most advanced AI models used by groups such as OpenAI and Anthropic. They say the issue has become more urgent after questions over the administration's handling of exports linked to Megaspeed.

Defense bill seen as key route for tougher controls

Backers of the legislation are now looking to attach the measures to the final version of the National Defense Authorization Act, or NDAA, the annual U.S. defense spending bill. Because the NDAA broadly funds the Department of Defense and is considered must-pass legislation, it offers a strong path for the export controls to become law.

The bill is due to be considered by the current Republican-majority Congress before lawmakers elected in November's midterm elections take their seats in January. The proposals this week also attract support from outgoing House Speaker Mike Johnson and his likely successor, Hakeem Jeffries, increasing their chances of staying in the final package.

Analysts in Washington say the political fallout from the Nvidia episode, combined with the post-election calendar, is shifting the outlook in favor of stricter oversight. Still, some aides caution that Congress faces a crowded year-end agenda and could run short of time.

The latest push also comes as lawmakers press Commerce Secretary Howard Lutnick to explain how Nvidia was allowed to sell chips to Megaspeed. American companies need licenses from the Commerce Department to export goods to entities on the U.S. blacklist, and scrutiny is intensifying over whether enforcement has been strong enough to keep advanced hardware out of China.

As we noted earlier, Congress chip export limits were gaining support after Nvidia said CEO Jensen Huang was stepping down amid a scandal.
