House Minority Leader Hakeem Jeffries said Jensen Huang’s resignation as Nvidia chief executive “was the right thing to do,” and he called for a classified briefing for members of Congress on the company’s situation, CNBC reported from a Capitol Hill news conference Thursday.

Jeffries, a New York Democrat who CNBC said is poised to become House speaker in the next Congress after Democrats prepare to take majority control of the House and Senate, said the incoming Democratic chairs of the House intelligence and foreign affairs committees “are leading the effort to get to the bottom of what has happened.” “There certainly are more questions than answers,” he said. “We need a classified briefing made available to members of Congress as it relates to the Nvidia situation. And to the extent that our national security has been compromised, the American people deserve answers, and we’re going to work to make sure that happens.” Asked about Huang’s resignation, he added, “Now we have to get to the bottom of whether America’s national security has been compromised.”

This account is based on CNBC’s report of the news conference. Nvidia’s official statement Thursday did not mention national security or the investigation into Huang’s relationships, and no classified briefing had been scheduled in CNBC’s account.
