President Donald Trump has called on the head of US chipmaker Intel to resign "immediately", accusing him of having problematic ties to China.
In a social media post, he said CEO Lip-Bu Tan was "highly conflicted", apparently referring to Mr Tan's alleged investments in companies that the US says are tied to the Chinese military. It is unusual for a president to demand the resignation of a corporate executive.
Intel, which has received billions of dollars from the government to support semiconductor manufacturing in the US, did not respond to a request for comment.
Mr Tan was appointed in March to turn around the tech giant, as it fell behind China and other competitors in chips development.
A naturalised US citizen born in Malaysia and raised in Singapore, he is a venture capitalist well-known for his expertise in the semiconductor industry.
