U.S. lawmakers are intensifying efforts to address national security concerns associated with TikTok, the Chinese-owned short video app. A bipartisan consensus is emerging, with Congress considering legislation that would force TikTok to sever ties with its parent company, ByteDance, and address issues of cybersecurity and data privacy. The House has already passed a bill, which is now under Senate consideration. Key figures, including the Senate Intelligence Chair, have suggested possible amendments to the bill, particularly regarding the 165-day timeline for ByteDance to divest its stake in TikTok. Senior officials from the Justice Department and other agencies are scheduled to brief skeptical senators in closed-door sessions on March 19 and 20, advocating for TikTok's operation in the U.S. contingent on its separation from ByteDance. Additionally, U.S. national security officials are set to hold a classified briefing for senators on the Commerce and Intelligence committees on March 20, focusing on the threats posed by foreign adversaries' exploitation of Americans' sensitive data through platforms like TikTok.
