US lawmakers press Commerce Secretary Lutnick on Nvidia chip export delays
US lawmakers are pressuring Commerce Secretary Howard Lutnick to explain delays in restricting chip exports to Megaspeed, a Singapore-based firm linked to an alleged Chinese spy, amid a deepening Nvidia controversy. Republican senators, including John Cornyn, demand Lutnick testify before Congress, citing "outrageous circumvention of national security export controls." Democrats have requested the department preserve documents related to the case, questioning whether political factors influenced decisions on export licences. The dispute follows Nvidia CEO Jensen Huang's resignation on Thursday amid revelations about his personal ties. Lawmakers also referenced Nvidia's $25 million donation to a Trump project, raising concerns about potential influence on administration actions.
