Huang resigned earlier on Thursday amid revelations of extramarital affairs, including with a woman US authorities suspect of spying for China.

The firm, which manufactures advanced chips powering artificial intelligence, has since seen its market value fall below $4 trillion for the first time since July 2025.

Amid the scandal, President Donald Trump’s administration faces allegations that Nvidia did not receive proper scrutiny for its exports of advanced semiconductors to China.

Lawmakers have also accused Lutnick’s Commerce Department of refusing to add dozens of Chinese companies to a US trade blacklist.

“Recent reports raise serious concerns about our national security and the protection of sensitive U.S. technology,” Scott wrote in a post on X. “The American people deserve answers.”

Three other House committees have asked Huang and Nvidia General Counsel Tim Teter to appear for separate hearings on December 1 and 2, or face subpoenas.

Under Secretary of Commerce Jeffrey Kessler was summoned for a December 3 hearing.

China has denied allegations of spying on the US. President Trump earlier defended Huang, calling him “honourable”.
