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.

The Supreme Court has upheld the federal law banning TikTok beginning Sunday unless it's sold by its China-based parent company, holding the risk to national security posed by its ties to China overcomes concerns about limiting speech by the app or its 170 million users in the U.

The US Supreme Court has upheld a law that bans TikTok in America unless its China-based parent company ByteDance sells the platform by this Sunday. TikTok had challenged the law, arguing it would violate free speech protections for the more than 170 million users it says it has in the US.
