Montana becomes first US state to ban TikTok

Greg Gianforte, the governor, signed legislation prohibiting mobile app stores from offering the video-sharing platform by next year

Montana has became the first US state to ban TikTok after the governor signed legislation prohibiting mobile application stores from offering the app within the state by next year.

The move is among the most dramatic in a series of US escalations against TikTok, which is owned by Chinese tech company ByteDance. TikTok has come under increasing scrutiny over its ties to China, amid concerns that such links could pose a national security threat.
