House Foreign Affairs chair: 'Very likely' chips restrictions make it into defense bill

• The chair of the House committee overseeing export controls says chip guardrails in a coming defense bill are likely.
• Rep. Brian Mast cast doubt on whether ousted Nvidia CEO Jensen Huang knew where his company's chips ended up.
• Mast is also pressing for Huang to testify soon about the scandal, Politico reported.

House Foreign Affairs Chair Brian Mast said Thursday it is "very likely" a group of bills that would impose new guardrails on exports of advanced US chips to China will make it into a must-pass annual defense bill this year.

The Florida Republican told reporters that the controversy involving Jensen Huang, who resigned as Nvidia's CEO earlier Thursday after revelations he had an extramarital relationship with a potential Chinese spy, has added momentum to the effort.

"If he doesn't know who he's in bed with, he doesn't know where all the chips are going either, and we know that for a fact," said Mast, whose committee oversees export control policy.

Lawmakers are discussing a trio of chip export control bills for the annual defense package, including the Chip Security Act, a measure that would crack down on smuggling by requiring advanced chips to contain location-verification mechanisms.

Two other measures are in the mix as well. One would tighten restrictions on chip-making equipment and push foreign countries to match US restrictions. The other would give Congress a chance to review licenses for advanced sales of AI chips.

President Donald Trump has been cool to the idea of tighter chip export restrictions and previously signed off on deals that allowed Nvidia to sell more of its high-end chips to China.

Mast also said Thursday that he still has confidence in Commerce Secretary Howard Lutnick, who is facing growing scrutiny over his handling of the Trump administration's chips policy. But he declined to say the same for a key Lutnick deputy, Jeffrey Kessler, who heads the Commerce Department bureau in charge of export controls.

Asked if he has confidence in Kessler, chief of the Bureau of Industry and Security, Mast said: "I'm not going to answer that yes or no. It's something that — you know, he's been most granular on this level and a lot of things about where chips can and can't be sold to. That's been more of an argumentative dynamic."

He also said he "absolutely" wants to investigate BIS' role in the Nvidia controversy.

A BIS spokesperson did not immediately respond to a request for comment.

Mast is pressing for Huang to testify soon about the scandal.

"We want to see him basically in a week," Mast said. "Sooner rather than later."

He is in talks with the former CEO's team, but didn't rule out a subpoena. Nvidia did not immediately respond to a request for comment.

"If negotiations shut off and we don't think they're in good faith, OK, fine, do that," he said. "I'll just subpoena you for the next day. No big deal."
