WASHINGTON (AP) — The CEO of TikTok will make a high-profile appearance Thursday before a U.S. Congressional committee to make the case for why the hugely popular video-sharing app shouldn’t be banned. Shou Zi Chew’s testimony comes at a crucial time for the company, which has acquired 150 million American users but is under increasing pressure from U.S. officials concerned about data security and user safety. TikTok and its parent company ByteDance have been swept up in a wider geopolitical battle between Beijing and Washington over trade and technology. Chew, a 40-year-old Singapore native, is making a rare public appearance to counter the volley of accusations that TikTok has been facing.
