U.S. Congress moves to tighten Nvidia chip export curbs on China

U.S. congressional consensus is growing to restrict Nvidia chip exports to China following a spy scandal that forced CEO Jensen Huang to resign, threatening China's access to advanced AI technology. House Speaker Mike Johnson cited bipartisan support for tougher limits after Huang stepped down over a reported relationship with a businesswoman suspected of spying for China. Lawmakers are pushing for stricter controls on AI chips, which underpin China's AI development. White House officials are also discussing whether to remove Commerce Secretary Howard Lutnick, according to sources, as pressure for decisive action mounts across Washington.
