The head of TikTok has been battling for the survival of the massively popular video-sharing app in the US. Yesterday, members of the House Energy and Commerce Committee, in Washington spent hours grilling Shou Zi Chew. They attacked Tiktok over its alleged ties to the Chinese government and the dangers they said it posed to teenagers. Many Democrats and Republicans fear that Beijing could subvert the app to spy, harvest data and push a covert Communist Party agenda. Concerns were also raised about the app's addictive qualities and its possible impact on mental health.
