The U.S. Supreme Court upheld on Friday a law banning TikTok in the United States on national security grounds if its Chinese parent company ByteDance does not sell the short-video app by Sunday, as the justices in a 9-0 decision declined to rescue a platform used by about half of all Americans.

Donald Trump had asked the Supreme Court to delay TikTok’s ban-or-sale law to give him an opportunity to act once he returns to the White House.

The Supreme Court ruled Friday that a controversial ban on TikTok may take effect this weekend, rejecting an appeal from the popular app’s owners that claimed the ban violated the First Amendment.

Meanwhile, the Justice Department is absolutely loving this. The Supreme Court's decision will allow it to "prevent the Chinese government from weaponizing TikTok to undermine America's national security," says Attorney General Merrick Garland. "Authoritarian regimes should not have unfettered access to millions of Americans' sensitive data."

A pending law would pressure China-based ByteDance to sell TikTok for the social media platform to be hosted by U.S. app stores.
