The Supreme Court on Friday unanimously upheld the federal law banning TikTok beginning Sunday unless it's sold by its China-based parent company, holding that 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 United States. A sale does not appear imminent and, although experts have said the app will not disappear from existing users' phones once the law takes effect, new users won't be able to download it and updates won't be available. That will eventually render the app unworkable, the Justice Department has said in court filings. The decision came against the backdrop of unusual political agitation by President-elect Donald Trump, who vowed that he could negotiate a solution, and the administration of President Joe Biden, which has signaled it won't enforce the law — which was passed with overwhelming bipartisan support — beginning Sunday, his final full day in office.
