Trump wants to include the head of Nvidia in his delegation to the trip to Asia, despite the internal investigation into Huang.
"I would definitely take him with me. I didn't hear him do anything wrong. He did business with somebody, but that's what everybody does," the US president told reporters.
Trump is scheduled to travel to Asia in a week to attend ASEAN summits in the Philippines and APEC meetings in China.
Earlier, Nvidia's board announced the start of an investigation against CEO Jensen Huang for cheating on his wife with a Chinese businesswoman suspected of spying for China.
Five months ago, Trump already took Huang with him on a trip to China, and then the media wrote that the American president "at the last minute" called the head of Nvidia. Trump was accompanied on his trip by "a dozen directors of American companies".
