Huang's confidence reportedly takes a hit
According to a report by NDTV, Huang's usually charming and confident demeanour reportedly disappeared in the final hours of his tenure as CEO.
As the controversy escalated and began raising questions about US national security, Huang allegedly started using phrases such as "whatever" and "I don't care".
People who remained in touch with him reportedly said the Nvidia chief appeared increasingly underconfident, even describing himself as "a piece of sh*t".
Affair controversy puts Huang under scrutiny
Huang had previously denied being unfaithful to his wife before eventually admitting to the alleged extramarital relationship.
Even during interviews, he maintained that his interactions with Alice were typical of a professional relationship between customers and executives.
The controversy reportedly intensified as allegations surrounding the relationship drew attention to its potential national security implications for the United States.
How the China spy scandal unfolded
The leadership crisis follows a report by The New York Times last month alleging that US intelligence agencies had uncovered a close relationship between Huang and Alice Huang, who was suspected of passing intelligence directly to Beijing.
Following Nvidia's announcement of an internal investigation on Sunday, US President Donald Trump confirmed on Monday that the FBI was also looking into the matter.
Nvidia has maintained that it has found no reason to suspect a breach of national security or the compromise of internal secrets.
However, the company said its investigation would examine all available information.
China, meanwhile, has denied any involvement in the alleged attempt to compromise the Nvidia chief.
Trump says Huang had no idea about alleged spy links
Trump said Huang had denied knowing that the woman was allegedly working as a spy and that he believed the Nvidia chief.
"I asked him that question, 'Did you have any idea that she was a spy?' He said, 'I had no idea that she was a spy' and I really believe him," Trump told reporters during a White House briefing.
The US President also confirmed that the FBI was investigating the matter, adding that he believed Huang would be "in good shape".
The controversy has put the spotlight on Nvidia's business dealings with China. Under Huang's leadership, the company emerged as the world's leading manufacturer of artificial intelligence (AI) chips.
His lobbying efforts in Washington also helped secure Trump administration approval in January for Nvidia to export its H200 chips to the Chinese market.
