Why is TikTok considered a national security threat in the United States?

TikTok has been officially declared a national security threat by prominent U.S. officials, including Ohio Republican Representative Mike Turner and Brendan Carr, the chairman of the Federal Communications Commission. This designation stems from concerns about the app's data collection practices and its connections to the Chinese government. The labeling of TikTok as a security threat has significant implications, leading to periods of removal from Apple and Google platforms in the U.S. and triggering ongoing legislative efforts to regulate the app's operations. These concerns center around potential data privacy issues and the possibility of misinformation spreading through the platform.
