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.

President Joe Biden appears to be backpedaling on the TikTok ban he signed last year. His administration is now saying it won’t enforce the law that will boot the popular platform from app stores, which is scheduled to begin on Sunday, the day before he leaves office.

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.

TikTok has gone dark in the U.S., the result of a federal law that bans the popular social media app for millions of Americans.

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-elect Donald Trump, who once called to ban TikTok, has since pledged to keep it available in the U.S.

The Biden administration doesn't plan to take action that forces TikTok to immediately go dark for U.S. users on Sunday, an administration official told ABC News.

TikTok said it would “go dark” on Sunday unless President Joe Biden’s administration offered assurance that it would not enforce a ban upheld Friday by the Supreme Court for the app’s U.S. operations to be sold or booted over “national security concerns.

Biden won't enforce the TikTok ban set for Sunday, January 19, his last day in office. It will be up to the Trump administration to enforce the law.
