Montana has become the first state to ban the popular social media app, TikTok. The ban was signed into law by Governor Greg Gianforte and has been challenged by TikTok in a U.S. District Court lawsuit, arguing that it violates the First Amendment. The company believes its legal challenge will prevail and the ban affects the hundreds of thousands of TikTok users in Montana. The lawsuit is the latest in a series of legal challenges to the app, which has been the subject of scrutiny from the U.S. government.
