On Thursday, TikTok CEO Shou Zi Chew will testify before the House Committee on Energy and Commerce to address concerns about the app's national security implications, consumer privacy, data security practices, and its relationship with the Chinese Communist Party. Chew has sought to reassure the public that the company is taking steps to protect user data, but a recent incident involving a reporter's data has raised questions about the company's commitment. The hearing will be closely watched to see if Chew's testimony is enough to allay the concerns of U.S. policymakers.
