WASHINGTON—Calls for an investigation into the security risks posed by the video app TikTok are widening, adding to pressure on President Biden to make good on his year-old promise to get tough on apps that could share Americans’ personal data with foreign adversaries.
The Democratic chairman of the Senate Intelligence Committee and the panel’s top Republican sent a joint letter to the Federal Trade Commission this week urging an investigation of TikTok’s data-handling and other practices. TikTok’s parent, ByteDance Ltd., has its headquarters in Beijing.
