Jensen Huang is out at Nvidia. Washington is just getting started with him and the company he co-founded.

Huang, the leather-jacket-clad CEO of the world's most important chipmaker, resigned from Nvidia on Thursday after revelations that he had an affair with a suspected Chinese spy. But the spy saga is gripping Washington, and lawmakers are preparing for investigations into how the now-ex-CEO's affair may have damaged U.S. artificial intelligence dominance, the national security implications and the executive's close relationship with President Donald Trump and his Cabinet.
