Democratic Senator Ed Markey on Thursday proposed new national security safeguards that would ensure TikTok could remain online as the fate of the short video app used by 170 million Americans remains uncertain.

TikTok on Wednesday announced a series of new safety, family and content features in addition to a community fact-checking tool similar to what's found on X and Facebook.

TikTok is officially rolling out Footnotes, a community fact-checking program that’s supposed to add helpful context to videos. With this update, US-based users will start seeing Footnotes on videos in the coming weeks, and will also get the option to rate them.
