Nvidia’s Jensen Huang expected to testify before Congress amid calls for crackdown on China chip exports – live

Jensen Huang has resigned as Nvidia’s chief executive, and is expected to testify before the US Congress within the next fortnight as lawmakers scrutinise his links to an alleged Chinese spy. His departure adds uncertainty at the world’s leading AI chipmaker and could affect the debate over US exports of advanced chips to China.

The allegations include reported relationships with two Nvidia employees and Alice Huang, who is accused of spying for China; Jensen Huang has denied knowing of her alleged government work and admitted to being unfaithful. Nvidia CFO Colette Kress will lead the company on an interim basis while the board considers successors. Nvidia shares fell 14% at the open before recovering to close more than 4% down, and lawmakers from both parties have called for tighter export restrictions.
