Republican senators publicly demanded that Jensen Huang resign, and a former economic advisor to Trump called for him to step down immediately

U.S. Republican Senator Kevin Cramer accepted an interview with POLITICO and publicly called for Jensen Huang to resign as CEO of NVIDIA. He believes that Huang's extramarital affair poses a serious potential blackmail risk, especially considering that NVIDIA holds highly sensitive AI chip technology. Cramer stated, "The risk of being blackmailed is just too great; I think he must go."Cramer is a member of the U.S. Senate Banking Committee, which is reviewing several bills aimed at strengthening export controls on advanced AI chips. He believes that while it is certainly possible for NVIDIA's board to initiate an internal investigation, it is far from enough. Earlier that day, Larry Kudlow, the former director of the White House National Economic Council during Trump's first term, also publicly urged on Fox Business, "Mr. Huang, resign now." He believes this is a reasonable action for Jensen Huang to take at this time.As the controversy escalates, the U.S. Congress is also accelerating its scrutiny of NVIDIA's chip exports. The three bills under consideration by the Senate Banking Committee involve strengthening export approvals for advanced chips, tracking the destination of chips, and restricting the export of certain semiconductor manufacturing equipment. These bills are vying to be included in the annual National Defense Authorization Act and have not yet been fully passed.
