Congress asks Nvidia's Jensen Huang for a closed-door briefing on spy reports

Republican Representatives John Moolenaar, Brian Mast and Rick Crawford sent a letter to Nvidia. They chair the House committees on China, Foreign Affairs and Intelligence.

They asked Jensen Huang for a joint, closed-door briefing. That means a private meeting where no cameras or press are present.

The letter says the reports "raise significant national security concerns" about China gaining access to US technology and information. The topics are:

• Security at Nvidia: how the company protects itself against spying by foreign governments.
• His contacts: Jensen Huang's interactions with Alice Huang, an executive at the company Megaspeed.

The request is an invitation to talk, not a subpoena (a legal order to appear). The reports do not say whether he has agreed to attend.

Alice Huang, also known as Huang Le, is a top executive at Megaspeed, a Singapore-based company that builds data centers. She is not related to Jensen Huang. They share a common surname.

Megaspeed is one of Nvidia's customers. It was set up in 2023 after a Chinese firm split off its overseas operation.

Reports say US officials have watched her for about a year. They describe her as having relationships with executives at the highest levels of the AI chip industry. She was photographed near Jensen Huang at events around the Computex trade show in Taipei in 2024 and again in 2025.

Reporters who dug into her background found gaps. A media job she was said to have held could not be confirmed by people at the outlets involved.

Unnamed US officials say that China's Ministry of State Security recruited Alice Huang. That is China's main spy agency. The aim, according to the report, was to learn about American AI chips and possibly to influence Nvidia to push for its most advanced chips to be made available to China.

Unnamed sources also say the same intelligence memo claimed Jensen Huang had a romantic relationship with her. Nobody has confirmed it publicly, and no document has been published.

Keep one thing in mind: none of this is proven. These are allegations passed on by anonymous officials. The Chinese embassy in Washington called them "groundless smears and slanders."

In real life think of a stranger who becomes friendly with the one person at a company who decides what gets built. Intelligence agencies call a setup like that a "honeypot," a relationship used to gather information. Whether that happened here is exactly what has not been shown.

Nvidia has pushed back. A spokesperson told reporters that Jensen Huang's interactions with Alice Huang were "not unusual" and that Nvidia does not share classified information with its customers.

The company also said that meetings with customers are part of a CEO's job. It says Jensen Huang talks with thousands of customer executives every year.

On the information side, Nvidia says its regional cloud customers receive ordinary business information. It says they get "not sensitive NVIDIA trade secrets" and "zero information relevant to national security."

This is not Megaspeed's first time in the news. US officials looked into whether the company helped Chinese firms get around American limits on AI chips.

The Commerce Department started looking after officials visited a Megaspeed data center in Malaysia. They reportedly found Nvidia equipment still in boxes. That raised the question of whether the hardware had just arrived or was about to be shipped on.

Megaspeed has been accused of helping move about $2 billion of advanced Nvidia chips to China through a subsidiary called Speedmatrix. Nvidia says those diversion claims were "thoroughly investigated and debunked last year." Reports also say the Justice Department is now leading a probe into Megaspeed.

The catch: the chip accusation and the spy reports are separate claims. One does not prove the other.

The US has rules called export controls. They block the most advanced AI chips from being sold to China, because those chips train and run the most powerful AI systems.

Nvidia makes the leading chips. When a buyer is a middleman, the rules are harder to enforce. A chip sold to a data center in Singapore or Malaysia could in theory end up somewhere else.

Reports also say Jensen Huang has lobbied the Trump administration to ease the limits on advanced chips for China. The concern raised by officials is that someone close to Nvidia's leadership could learn how that effort is going. That is the reason lawmakers care about who he talks to.

Singapore opened its own investigation into Megaspeed. Its government told reporters that it does not carry out export controls set by other countries. It said it takes a "zero-tolerance stance" on commercial fraud. It also said it is not targeting Alice Huang or looking into her claimed ties to Jensen Huang or China.

Taiwan is also reportedly looking at her visits there. Taiwanese authorities have reportedly placed her under physical surveillance, according to unnamed sources. Taiwan has not publicly commented.

Reports also say President Donald Trump was briefed on the situation last year and did not act. Unnamed officials say Jensen Huang never received a defensive briefing. That is a warning agencies sometimes give to people who may be spy targets. Officials often hold back such warnings so that the person under watch does not realize they are being investigated.

The next step is whether Jensen Huang accepts the invitation and when. Nothing in the reports sets a date.

A closed-door session means the public may learn little of what is said. Lawmakers could still publish a summary or ask more questions of Nvidia and Megaspeed.

The Justice Department's work on Megaspeed and the Singapore case run on their own timelines. Any charges or findings would be new facts. Until then, the central claims stay unproven.

• Chip rules are in play: the debate decides how easily the best AI chips reach China, which affects prices, supply and AI progress.
• Treat the allegations carefully: they come from unnamed officials. Wait for confirmed facts before drawing conclusions about any person.
• Nvidia's stock and products: nothing here changes what Nvidia sells today, but the outcome could shape future export rules.
• Watch for official statements: a published summary of the briefing or a court filing would be the first hard evidence.
