Rubio used the scandal surrounding Nvidia CEO Huang to weaken his influence over Trump. He prepared a memo for Trump warning about Huang's ties to Huang in China. The document was based on a CIA report. Rubio, according to the newspaper's interlocutors, rewrote the intelligence findings in harsher terms. When the contents of the memo were leaked to the press, it set off a chain of events that culminated in Huang's resignation.
Many on Trump's national security team have long been unhappy with Huang's influence over the president and have not shared his views on chip exports to China. Huang's resignation was a victory for China hawks, a bipartisan group of officials and lawmakers who pushed for tougher export controls.
Now Congress plans to seize the moment and include new restrictions on China's access to chips in the defense bill before the end of the year. WAPO.
