U.S. Senate summons Nvidia's Huang and Commerce's Lutnick to testify

The U.S. Senate Banking Committee has requested former Nvidia CEO Jensen Huang and Commerce Secretary Howard Lutnick testify separately before Congress next month amid national security concerns, according to a Politico report Friday. Senator Tim Scott sent letters asking Huang to testify on December 3 and Lutnick on December 10, warning Huang he could face a subpoena if he declines, citing reports about his ties to a potential Chinese spy. Huang resigned as Nvidia's CEO Thursday, intensifying scrutiny of the AI chipmaker's exports to China. The request to Lutnick focuses on the Commerce Department's role in export controls, with Republicans questioning his handling of semiconductor policy. Nvidia remains central to the broader debate over whether advanced AI chip sales to China threaten U.S. national security.
