The US Supreme Court has upheld a law banning TikTok nationwide unless China-based parent company ByteDance sells the platform by Sunday.
TikTok has challenged the law, arguing that it violates free speech protections for the app's more than 170 million users in the United States.
But that argument was rejected by the country's highest court, meaning TikTok must now find an approved buyer for the US version of the app or face removal from app stores and web hosting services.
However, the outgoing Biden administration and incoming President Donald Trump are trying to reach a reprieve for the platform, which US authorities have warned poses a national security risk.
