TikTok CEO Resigns as Tensions Mount With White House VOA News The head of TikTok resigned Wednesday as tensions mount between the Chinese-owned video platform and the White House, which contends TikTok is a security risk in the U.S. Chief Executive Officer Kevin Mayer announced his resignation days after the company filed a lawsuit challenging a U.S. government crackdown on the company over claims the social media app can be a tool to spy on U.S. citizens. Mayer, a former Disney executive who joined the company in May, said in letter to employees his decision to quit came after the "political environment has sharply changed" in recent weeks. "I understand that the role that I signed up for, including running TikTok globally, will look very different as a result of the U.S. administration's action to push for a sell-off of the U.S. business." U.S. President Donald Trump signed an executive order on August 6 banning TikTok unless its parent company, ByteDance, sells its U.S. operations to an American company within 90 days. .
