The former Nvidia CEO resigned after admitting reports of two extramarital affairs came to the fore. The two women are Alice Huang, who is suspected of being a Chinese spy, and Kimberly Powell, Nvidia's vice president of healthcare. Amid the ongoing Nvidia controversy, Elon Musk has backed its former CEO Jensen Huang once again. Musk said late Friday night that he would sign the petition by Nvidia employees to reinstate Huang.
