TikTok sues Montana, saying state ban violates First Amendment

The popular video app TikTok sued Montana on Monday, saying the state’s new law banning the app statewide would violate Americans’ First Amendment right to free expression.

The federal lawsuit will set the stage for a broader debate over the short-video app and its Chinese parent company, ByteDance, which some critics in the United States have said is vulnerable to Chinese government propaganda and espionage.
