TikTok CEO Kevin Mayer resigned Thursday amid US pressure for its Chinese owner to sell the popular video app, which the White House says is a security risk.
TikTok General Manager Vanessa Pappas will replace Kevin Mayer on an interim basis.
Mr Mayer had joined TikTok following a long and successful career at Disney, most recently as chairman of its direct-to-consumer and international businesses, according to TikTok’s website.
TikTok gained immense popularity via its fun, goofy videos and ease of use, and has hundreds of millions of users globally.
But its Chinese ownership has raised concerns about potential censorship of videos, including those critical of the Chinese government, and the risk Beijing may access user data.
Earlier this month, Trump ordered a sweeping but unspecified ban on dealings with the Chinese owners of consumer apps TikTok and WeChat as the US heightens scrutiny of Chinese technology companies, citing concerns that they may pose a threat to national security.
