The Silicon Valley superstar engulfed by personal scandal

He rose to prominence as the business he leads - artificial intelligence (AI) chip giant Nvidia - became one of the world's most valuable companies. As the face of the AI boom, Huang also became close to Donald Trump as the president pushed for the US to keep its dominance of the technology over China. The 63-year-old who was once lauded as the "Taylor Swift of tech" and referred to as "Daddy Huang" in Taiwan is now mired in scandal after an affair with a suspected Chinese spy.

He graduated as an electrical engineer from Oregon State University, and then with a master's degree in the same field from Stanford University. Huang has a famously close relationship with Trump. At the recent AI summit at the White House, where 42 tech executives were present, the president was flanked by Elon Musk and Huang.

"I just know he's a fine person, but you never know what's going on," Trump told reporters, adding that he had "done an amazing job for our country". Huang has long found himself at the centre of US-China tensions. Trump has repeatedly said the two nations are in a race for dominance.
