TikTok CEO grilled for over five hours on China, drugs and teen mental health

Shou Zi Chew attempts to play down concerns over data and privacy as lawmakers call for ban on Chinese-owned app

The chief executive of TikTok, Shou Zi Chew, was forced to defend his company's relationship with China, as well as the protections for its youngest users, at a testy congressional hearing on Thursday that came amid a bipartisan push to ban the app entirely in the US over national security concerns.

The hearing marked the first ever appearance before US lawmakers by a TikTok chief executive, and a rare public outing for the 4o-year-old Chew, who has remained largely out of the limelight as the social network's popularity soars. TikTok now boasts tens of millions of US users, but lawmakers have long held concerns over China's control over the app, which Chew repeatedly tried to assuage throughout the hearing. Let me state this unequivocally: ByteDance is not an agent of China or any other country," Chew said in Thursday's testimony.
