President Joe Biden's administration said it will be up to President-elect Donald Trump to implement the ban on TikTok, which is set to take effect in two days after the Supreme Court upheld the law Friday.

Congress last year in a law signed by President Joe Biden required that TikTok’s China-based parent company ByteDance divest the company by Jan. 19 or risk getting banned in the U.S.

The White House has looked into options to keep TikTok accessible to its 170 million American users if a ban that is set to go into effect Sunday continues as planned.

President Joe Biden is reportedly not planning to enforce TikTok’s ban on Jan. 19, and is opting to leave the fate of the app in President-elect Donald Trump’s hands. Speaking on condition of anonymity,

President Biden will not enforce a ban on TikTok that is set to take effect Sunday, a U.S. official said, leaving its fate to Donald Trump.

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.

As a ban looms over the social media app and its 170 million users, TikTok said it will be “forced to go dark” on Sunday unless the Biden administration explicitly declares that it will not enforce the ban.

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.
