WASHINGTON — Senate Minority Leader Chuck Schumer and several Democratic senators are pressing Majority Leader John Thune to bring three measures aimed at restricting China’s access to advanced artificial-intelligence chips and semiconductor manufacturing equipment to the Senate floor. Schumer made the demand Wednesday alongside Sens. Elizabeth Warren of Massachusetts, Andy Kim of New Jersey and Elissa Slotkin of Michigan. They called for votes on the AI OVERWATCH Act, the MATCH Act and the Chip Security Act, arguing that the measures would strengthen national security and limit the transfer of cutting-edge U.S. technology to China. “The Senate could pass all three bills today and protect our national security and keep U.S. AI tech out of China’s hands,” Schumer said at a Democratic news briefing. He accused Trump of giving China technology needed to compete with the United States in artificial intelligence. The lawmakers’ push comes as Chinese President Xi Jinping travels to Washington for a summit with Trump. The leaders are expected to discuss the shared risks posed by increasingly capable AI systems, as well as the broader competition between the two countries over technology and national security. The timing may make congressional action difficult. The Senate is approaching its final legislative week before the midterm elections, leaving limited time for lawmakers to advance new legislation. The three measures are among more than a dozen bipartisan proposals introduced over the past year to tighten oversight of AI-chip exports to China. The bills were included in a Senate manager’s amendment package for the National Defense Authorization Act, raising the possibility that they could be attached to the annual defense policy measure. Their House counterparts cleared committees earlier this year. Rep. Brian Mast, a Florida Republican who chairs the House Foreign Affairs Committee, has pushed to include the export-control measures in the defense package. The Senate’s $1.15 trillion defense policy bill was blocked by Democrats in July in protest of the administration’s war in Iran, adding another obstacle to negotiations over the legislation. Warren also sent Trump a letter Tuesday warning him against allowing Nvidia CEO Jensen Huang to participate in negotiations with Xi. Warren, a co-sponsor of the AI OVERWATCH Act, has criticized Huang’s lobbying efforts to permit Nvidia to sell advanced AI chips to China. “We certainly should not be letting tech billionaires like Nvidia’s Jensen Huang negotiate away our export controls or decide our AI policy to benefit his own personal bottom line,” Warren said at the briefing. The senators also criticized Trump’s decision late last year to permit Nvidia’s H200 chips to be exported to China. They said those sales could give Beijing an advantage in the global AI race. Nvidia had not immediately responded to a request for comment. The debate reflects a broader policy dilemma for Congress: how to protect U.S. technological leadership and national security without allowing major corporations to determine export policy behind closed doors. For communities tied to the semiconductor industry, the outcome could affect supply chains, research partnerships and the balance between economic growth and safeguards on powerful computing technology.
