Washington — The Supreme Court on Friday upheld a new law that would lead to a ban of the social media platform TikTok, clearing the way for the widely popular app to shutter in the U.S. as soon as Sunday.

The Supreme Court’s remarkably speedy decision Friday to allow a controversial ban on TikTok to take hold will have a dramatic impact on the tens of millions of Americans who visit the app every day and broad political implications for President-elect Donald Trump.

TikTok CEO Shou Chew on Friday responded to the Supreme Court’s decision to uphold the law requiring the app to sell its U.S.-based operations to a non-Chinese buyer or face a ban in the U.S. The law will prohibit app stores like Apple’s App Store and Google Play,
