Scrutiny intensified over the extent of the Trump administration’s knowledge of Nvidia CEO Jensen Huang’s relationship with an alleged Chinese spy, a scandal that comes just a week before a superpower summit. US President Donald Trump was told in May, while en route to China, that Washington had intelligence of Huang’s extramarital affair with the Chinese executive, The New York Times reported, while Axios said Trump’s commerce secretary was sent a memo warning about the affair.

The commerce department is reportedly delaying attempts to blacklist the company the woman works for; it stands accused of smuggling advanced chips to China. A US lawmaker will today press the White House for updates on its investigations into the firm.
