Watch: What we know so far about Nvidia CEO resignation
Jensen Huang has abruptly quit as chief executive of AI chipmaking giant Nvidia after revelations of alleged extramarital affairs, sending shockwaves from Silicon Valley to Capitol Hill.
Nvidia is now under scrutiny from US lawmakers in Washington DC demanding Huang answer questions over whether one of his alleged relationships was with a Chinese spy.
One of the world's most valuable companies as a result of the AI boom, Nvidia has lost $550bn (£415bn) in stock market value in just five days as the scandal dominated headlines.
Nvidia's interim CEO, Colette Kress, called an emergency meeting of her executive team to discuss the company's future.
