The U.S. Supreme Court today upheld a lower court ruling that the app TikTok owned by China’s ByteDance must sell itself or be banned in the U.S.

Justices reject the Chinese app’s First Amendment challenge to a federal law against “foreign adversary” control.

TikTok, ByteDance and several users of the app sued to halt the ban, arguing it would suppress free speech for the millions of Americans who use the platform.

The U.S. Supreme Court on Friday unanimously upheld a law passed in Congress that bans TikTok, which could lead to 3.7 million users in Michigan losing the use of the app as soon as Sunday. The court's decision shifts focus to President-elect Donald Trump, who still can intervene after he is sworn into office on Monday.

The U.S. Supreme Court heard oral arguments last Friday from TikTok, which claims the ban is a breach of American's First Amendment rights. And after more than a week, the court handed down its decision to uphold law that could ban TikTok in the U.S.

U.S. lawmakers on both sides of the aisle hailed a ruling by the Supreme Court on Friday that upheld a law that gives popular Chinese-owned social media app TikTok until Sunday to be bought by an American company or be banned.

With the ban upheld by the Supreme Court and the Biden administration leaving, TikTok CEO Shou Zi Chew is banking on Trump to save the app in the US.

The U.S. Supreme Court officially upheld the law to ban the TikTok social media app on Friday.

TikTok's Saturday black-out comes after the Supreme Court upheld a ban that was passed into law in April. It prevents United States companies from hosting or creating content on the Chinese-owned social media platform, unless it sells to a buyer from the US or one of its allies.

Sen. Tom Cotton (R-AR), one of the biggest China hawks in the GOP, disputed Donald Trump's goal of allowing the platform to remain online and extend the deadline for the sale.
