TikTok CEO Shou Zi Chew is set to face a grilling from US lawmakers this Thursday in his first sworn testimony before Congress, with the hearing focusing on data privacy and security. In preparation, Chew has been taking part in near-daily, multi-hour prep sessions with TikTok personnel and the app has organized a gathering of creators in D.C. to show their support. The hearing is expected to be a high-stakes event, with Chew’s performance likely to have a major impact on the future of the app in the US.
