Ron Wyden and Richard Neal asked Commerce to preserve records as they question whether the arrangement amounts to an unconstitutional export tax.
Listen to this story
The arrangement under scrutiny would route Taiwan-made Nvidia chips through the United States for a security review, collect a 25% tariff, then allow their export to Chinese buyers under Commerce Department licenses. Senators Ron Wyden and Richard Neal are seeking records to determine how the administration used Section 232, a law governing threatening imports, in a process they argue may function as an unconstitutional export tax. The inquiry could clarify how tariff and export-control powers are being combined; the cited press reports and allegations are not findings of the investigation.
The records request covers the Section 232 semiconductor inquiry and tariffs, Nvidia export-license decisions, and communications involving Nvidia, Jensen Huang, or their representatives.
Wyden and Neal say Section 232 was intended to address imports that threaten national security, not facilitate exports to China.
The lawmakers cite reports that Commerce paused a suspected chip-smuggling investigation after outreach from Nvidia; the reported sequence does not establish that Nvidia caused the pause.
Ron Wyden and Richard Neal opened an investigation on November 12, 2026, into the Trump administration’s handling of Nvidia AI-chip sales to China. They demanded that the Commerce Department preserve related records, challenging an arrangement they describe as letting the government collect a cut of sales through a national-security tariff.
Wyden, the Senate Finance Committee’s ranking Democrat, and Neal, the House Ways and Means Committee’s ranking Democrat, are examining decisions that combine tariff policy with export permissions. Their committees oversee taxation and trade.
The process described in the lawmakers’ release has two stages. Nvidia chips manufactured in Taiwan would first enter the United States for a security review, triggering a 25% tariff. The Commerce Department would then grant an export license allowing Nvidia to sell the chips to Chinese companies.
The legal vehicle, according to the release, is Section 232 of the Trade Expansion Act of 1962. That law addresses imports that threaten national security. Wyden and Neal characterize the arrangement as an attempt to disguise an unconstitutional export tax as a national-security tariff.
Congress wrote Section 232 to give the President a tool to take action against imports he has determined to pose a national security threat; Trump’s use of the statute appears to have done the opposite, undermining U.S. national security and putting Americans at risk.

The preservation demand covers three categories:
The lawmakers also cited press reports alleging that President Donald Trump and Commerce Secretary Howard Lutnick had been briefed about Jensen Huang’s relationship with an alleged Chinese intelligence asset but nevertheless approved advanced AI-chip exports to China. Those allegations are grounds for the inquiry, not findings produced by it.
Citing press reports, the release says Commerce suspended an investigation into suspected smuggling of certain Nvidia chips into China after outreach from the company. That reported sequence does not, by itself, establish that Nvidia caused the investigation to stop.
The release additionally states that Nvidia and Huang donated at least $26 million to Trump’s projects. It does not establish that the donations determined a tariff, licensing or enforcement decision.
