Nvidia has hired the law firm Wechtel Lipton to conduct an internal investigation into possible foreign espionage, the Wall Street Journal writes. The inspection was carried out against the background of reports of personal relationships between the company's CEO Jensen Huang and a senior manager at the Singaporean Mega Speed company, who is suspected of being a fact for Chinese intelligence. According to Nvidia, there is no evidence yet of a leak of corporate secrets, but the investigation led by former federal prosecutor John Kim will study all available data.
