TikTok CEO defends app's impact on US economy and user privacy in congressional hearing.

TikTok CEO Shou Zi Chew will testify before Congress that banning the app in the U.S. would hurt American businesses and the country's economy. The Biden administration has warned the firm that it faces a ban in the United States if its parents company, ByteDance, doesn't sell its stake in the U.S. version of the app amid national security concerns. Chew will make four key commitments to keep TikTok's American users safe, including keeping safety a top priority and firewalling protected U.S. user data from unauthorized foreign access.
