TikTok and China’s ByteDance sue to block US law seeking sale or ban of app

TikTok and its Chinese parent company ByteDance filed a federal lawsuit on Tuesday seeking to block a US law that would force the divestiture of the popular short-video app or ban its use nationwide.

The companies filed the suit in the US Court of Appeals for the District of Columbia arguing that the law violates the First Amendment of the US Constitution, which protects free speech, as well as several other constitutional provisions.
