The Supreme Court ruled on Friday, Jan. 17, to uphold a law that would ban the app for the 170 million people who use the app in the U.S. The ruling lines up with decisions other courts have made and sets up the ban to go into effect on Sunday, Jan. 19.

The White House said on Friday that Tiktok should remain available to Americans but the timing of the Supreme Court ruling on a law banning the app means it must fall to the Trump administration.

TikTok went dark for users across the U.S. late Saturday as the app notified users of a ban that went into effect just days before President-elect Trump's inauguration.

By now you've almost certainly heard that TikTok could be about to get banned in the US this coming Sunday, January 19. The latest update today is that the social platform will "go dark" amid uncertainty around what the White House will actually decide to do.

"TikTok and ByteDance Ltd. apps are no longer available in the United States, and visitors to the United States might have limited access to features," Apple said.

President-elect Donald Trump is spending the eve of his inauguration in a series of Washington events that celebrate his return to power and his “Make America Great Again” movement as he prepares to move back into the White House at a time of deep national political divisions.

President-elect Donald Trump publicly said Saturday that he will probably give TikTok a 90-day reprieve from a U.S. ban set to take effect Sunday, just before he takes office.

TikTok said it will be forced to go dark on January 19, the day the ban is set to take effect, without more assurances it won't be enforced.

TikTok's app was removed from prominent app stores on Saturday evening just before a federal law that bans the popular social media platform went into effect.

TikTok became unavailable in U.S. on Saturday evening after Supreme Court upheld the ban. Follow along for live updates.
