The U.S. Senate Banking Committee has given Jensen Huang and Commerce Secretary Howard Lutnick a choice: appear voluntarily in December or face subpoenas. The committee confirmed overnight that Huang, Nvidia's former CEO, is asked to testify on December 3 and Lutnick on December 10.

Senator Tim Scott of South Carolina, the committee's chairman, set the terms bluntly. "Recent reports raise serious concerns about our national security and the protection of sensitive U.S. technology," he said. "The American people deserve answers."

His letter carried a sharper warning. If either man declines to appear voluntarily, the committee is "prepared to use all tools at our disposal, including subpoenas, to conduct this legitimate and necessary oversight." That is committee language for: attendance is not optional in practice. What remains unsaid is precisely which export decisions the committee intends to challenge first.

Why the committee has jurisdiction

Scott's letter to Huang lays out the legal basis. The committee holds "jurisdiction over matters relating to 'export controls,' including their application to NVIDIA's exports of advanced semiconductors" — the government rules restricting which high-end chips (the processors powering artificial intelligence) may be sold to foreign buyers, above all China.

The committee said in a post on X that it is "seeking answers to questions that raise grave national security concerns." It did not publish the specific questions. That gap matters: witnesses are preparing testimony without knowing the exact allegations they will face.

The scandal behind the summons

The hearing is the latest development in a fast-moving sequence. Huang resigned from Nvidia, the company he spent 30 years building, after admitting an extramarital affair with a woman believed to be a Chinese spy, identified as Alice Huang (no relation). China has denied any involvement.

The story has since widened. Reports have surfaced of an affair with Nvidia executive Kimberly Powell, and Reuters reported yesterday, citing unnamed sources, that Huang had a second relationship with a member of staff. Nvidia has not commented on those reports beyond confirming its internal review.

The company's board has launched its own independent investigation and hired Joon H. Kim, former acting U.S. Attorney for the Southern District of New York, now at Wachtell, Lipton, Rosen & Katz, to lead it. An outside counsel of that stature signals the board expects the review to face legal, not merely reputational, scrutiny. President Trump told reporters earlier this week that the FBI is investigating the affair with the alleged spy.

Colette Kress, Nvidia's chief financial officer, has been named interim CEO following the resignation.

What are the accusations against Lutnick?

Committee members have suggested the Commerce Secretary allowed loopholes to persist that let high-end chips keep flowing to China. Senator Jim Banks, Republican of Indiana, told Fox News last night that he believed Lutnick had "defied President Trump's directive not to sell these high-end chips to China or to allow them to be sold to Chinese customers, that ended up happening anyway."

That is a serious charge: a cabinet member allegedly contradicting a direct presidential directive. Banks offered no documented cases in the interview, and the committee has not yet published evidence — a caveat worth holding onto until December 3.

Senator Elizabeth Warren of Massachusetts, the committee's ranking Democrat, aimed at the same target. "Secretary Howard Lutnick and Under Secretary Jeffrey 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," she said.

Note the second name. Warren's statement extends the demand to Jeffrey Kessler, the under secretary — a signal that senators view the enforcement failure, if there is one, as institutional rather than personal.

What should Huang expect in the room?

Hostility, from both parties. Senator John Kennedy, Republican of Louisiana, told CNN last night: "I'm not naive; I'm not Bambi's baby brother. I know people have affairs; I wouldn't recommend it, but if you do, you ought to make sure it's not with a Chinese spy. I mean, check their LinkedIn page for God's sake."

Kennedy framed the stakes more soberly in the same interview, calling the affair an "intergalactic freak show" and adding: "Here's a man, head of one of the most powerful companies in the world, more than anybody else in the private sector; he's been making AI policy for America, and certainly with respect to our relationship with China. And then we learn about this."

What does this change for Nvidia and chip policy?

In the near term, the hearings will keep export-control enforcement at the top of the Washington agenda, with both parties competing to appear tougher on China. For Nvidia, the interim leadership under Kress now faces a Senate inquiry layered on top of an FBI investigation and a board review — three parallel processes, none of them under the company's control. Whether any of the three produces evidence of actual technology leakage, rather than personal misconduct, is the question December's testimony may begin to answer.
