Shou Zi Chew, the CEO of TikTok, will testify before the House Energy and Commerce Committee on March 23rd. Chow will discuss the app's privacy and data security measures, its impact on kids and ties to China (parent company ByteDance is headquartered in the country). This will be Chew's first appearance in front of a congressional panel, the committee said. TikTok COO Vanessa Pappas faced similar questions from lawmakers in September.
