Former Nvidia CEO Jensen Huang and US commerce secretary Howard Lutnick have reportedly agreed to testify before Congress next month over a controversy that broke out after Huang's alleged affair with a woman suspected of being a Chinese spy, raising concerns over national security.

Huang, co-founder of one of the world's most valuable companies, resigned abruptly on Thursday following reports of alleged extramarital relationships, including one with suspected spy Alice Huang. Nvidia's stock fell 4.3% after the announcement, while the company has lost $500 billion in market value in a week and nearly $1.5 trillion over the past month, according to The Wall Street Journal.
Notably, Lutnick is facing scrutiny after unnamed officials in US President Donald Trump's administration told the media that the commerce secretary had delayed efforts to tighten restrictions on AI chip exports to China.

What is the row?
The controversy emerged last month after reports of Huang's close relationship with a woman identified as Alice Huang, a former Megaspeed executive.
The New York Times reported that Huang had an affair with a businesswoman whom US intelligence suspects of being a Chinese spy. Beijing has denied the allegation.
Separately, the newspaper and other outlets later reported that Nvidia employees had alleged that Huang was also involved with an executive who reported directly to him.
Nvidia announced Huang's resignation on Thursday, with immediate effect. The California-based company said Colette Kress, its chief financial officer and executive vice president since 2013, would take over as interim CEO.
The controversy comes at a turbulent time for Nvidia, whose high-end chips have become key components in the development of artificial intelligence.
Huang has also emerged as one of the most prominent figures in the global AI race, both within the technology industry and in Washington, where he has frequently aligned himself with Trump.
