House lawmakers are set to meet next month with the CEO of TikTok at a hearing to probe whether one of the most popular apps in the world shares Americans’ data with China and whether it harms young children, the latest face-off between members of Congress and the head of a large social media platform. Rep. Cathy McMorris Rodgers, R-Wash., chair of the House Energy and Commerce Committee, who has made Big Tech accountability a key part of her agenda, said Monday that TikTok CEO Shou Zi Chew would appear before the committee for the first time on March 23.
