TikTok says it plans to go offline on Sunday, January 19th if the Biden administration doesn’t intervene. The company confirms earlier reporting that it will be “forced to go dark” on the 19th unless the outgoing administration provides a “definitive statement” assuring its “most critical service providers” that they won’t be held liable for breaking the law.

TikTok said its services will go dark on Sunday unless the Biden administration gives a definitive statement providing assurances for Apple, Google and other service providers. The Supreme Court on Friday ruled unanimously to uphold a law requiring that parent company ByteDance sell TikTok or see it be effectively banned in the U.

As politicians scramble over TikTok in Washington, the window for President Joe Biden to rescue TikTok appears to be slamming shut.
