Marco Rubio caused downfall of Jensen Huang, the billionaire's biographer claims

Jensen Huang's biographer Stephen Witt said US Secretary of State Marco Rubio was behind the billionaire's downfall. "[Huang] persuaded President [Donald Trump] to lift export restrictions on NVIDIA chips to China, and this put him in conflict with the more hawkish members of [Trump's] staff-especially Rubio," Witt said. "It was Rubio who oversaw the memo that exposed Huang," he added.
