Commerce Secretary Lutnick Faces Congressional Heat After Nvidia Scandal

What happened

Howard Lutnick, who ultimately oversees US export controls, is facing questions about any policy or enforcement gaps that let Nvidia's AI processors reach unauthorized Chinese buyers. He still has backing from President Donald Trump, who offered a vote of confidence just hours after Jensen Huang's resignation on Thursday.

Huang stepped down after disclosures of a relationship with Alice Huang, who US officials suspect of spying for China. Her Singapore firm, Megaspeed, has been under Commerce Department investigation for possible export control violations and has denied wrongdoing. Alice Huang is now in China. Founded in 2023, Megaspeed brought in no less than $4.6 billion of Nvidia equipment, which made it the company's biggest buyer in Singapore.

Why Congress is pressing

Members of Congress are seeking explanations from Lutnick and fellow administration officials regarding whether any choices facilitated China's access to Nvidia's top-tier chips, as well as the extent of influence figures such as Jensen Huang had on those policies. That pressure intensified one week after an election in which voters expressed strong dissatisfaction with the AI surge.

Senator Jim Banks said on Fox News, "I would like for Secretary Lutnick ASAP to come testify before the Senate Banking Committee because we have a lot of bipartisan questions and concerns about what's happened over the last year." Axios reported that Trump approved stricter actions targeting companies believed to be funneling advanced AI chips to China, yet Lutnick postponed taking action. Representative Raja Krishnamoorthi called that report "deeply, deeply disturbing," adding on Bloomberg Television that the week's events are "a freaking disaster" that should draw review from Nvidia's board, U.S. intelligence agencies, and the federal government.

People tied to the White House say Lutnick has long been sidelined inside the administration, and although his departure has been predicted before, it still hasn't occurred. A White House official said Trump continues to have full confidence in Lutnick and characterized him as the most transformative leader of the Commerce Department in modern history.

Inside BIS and Kessler

A key flashpoint is the Bureau of Industry and Security, a low-profile but powerful Commerce agency that regulates exports of items including advanced AI chips and reports up to Lutnick. Lawmakers are threatening probes into BIS chief Under Secretary Jeffrey Kessler. Senator Elizabeth Warren said the Senate Banking Committee has plans underway for inquiries and that Lutnick and Kessler "must explain why they have not closed export control loopholes and act today to ensure our advanced technology is not fueling China's military."

According to Bloomberg, in late summer 2025, Nvidia's general counsel Tim Teter got in touch with Kessler to inquire whether BIS had any involvement in Alice Huang's recent detention by Singaporean authorities. Bloomberg earlier said BIS was not involved, citing individuals with direct knowledge. A spokesperson for Nvidia said that when he made the call, Teter did not know about the affair.

In the weeks after, BIS staff were restricted in their ability to investigate Nvidia, including a directive to route all requests regarding the company through Kessler, according to Bloomberg. BIS spokespeople have previously denied wrongdoing. On Bloomberg Television, Ben Buchanan, who served as the White House's special adviser for AI under the Biden administration, said, "This is an incident where the enforcement is not good. The decision making has not been good."

Further complicating the picture, Democratic lawmakers allege Lutnick's sons, who hold leadership roles at Cantor Fitzgerald, are benefiting from policy decisions he makes. Before taking the secretary post, Lutnick - formerly Cantor's CEO - sold his ownership interest to meet legal obligations and later placed his sons in senior roles at the company. The Commerce Department did not provide a comment right away, and Cantor Fitzgerald declined to comment.

What this means for your portfolio

The bottom line: Congress is zeroing in on whether export-control decisions let Nvidia's high end chips slip to unauthorized Chinese buyers, and whether BIS oversight under Kessler held up. That mix of hearings, investigations and political heat could translate into tighter rules, faster enforcement and more scrutiny for companies building or selling advanced AI hardware.

If your portfolio is exposed to AI chip makers or their supply chains, expect more regulatory attention on cross border sales. The near term impact hinges on what Commerce does next, how BIS operates under scrutiny, and what formal findings emerge from planned inquiries.
