When the Supreme Court justices first shared an inaugural stage with Donald Trump, they heard the new president deliver a 16-minute declaration against the country and vow, “This American carnage stops right here and stops right now.

TikTok is set to be banned in the US on 19 January after the Supreme Court denied a last ditch legal bid from its Chinese owner, ByteDance. It found the law banning the social media platform did not violate the first amendment rights of TikTok and its 170 million users, as the companies argued.

The U.S. Supreme Court’s decision could come Friday in the case about whether TikTok must shut down in a few days under a federal law that seeks to force its sale by the Chinese company that owns the social media platform.
