Nvidia CEO Jensen Huang, the preeminent face of the artificial intelligence infrastructure boom, has been ousted from his post after reports of three affairs, including one with a woman suspected of spying for China.

Longtime CFO Colette Kress is taking the job of interim CEO, Nvidia said on Thursday, and Huang will no longer have ties with the chipmaker. The board, which has never had a chair before, appointed director Harvey Jones to that role. Jones, 73, formerly led Synopsys, a company that Nvidia took a $2 billion stake in last year.

The resignation deepens a crisis partly of Nvidia’s own making, since the company has long lacked a clear succession plan. The 63-year-old has been Nvidia’s only CEO during its three-decade history. He carefully managed every part of the business, while also serving as a cheerleader for the broader AI industry.
