U.S. Sen. Tom Cotton (R., Ark.) had earlier this week sent a letter to Yeary, the Intel board chair, questioning him about Tan’s ties to Chinese firms. Sen. Bernie Moreno of Ohio, where Intel has delayed plans to build new facilities, joined in Thursday, calling for Tan to resign.

President Donald Trump urged the chief executive officer of Intel Corp. to resign over what he called conflicts of interest, injecting fresh turmoil at a company already struggling to stem losses and eke out relevance in the artificial intelligence age.
