Montana has become the first state to ban TikTok. Here's what happens next.

Montana has officially become the first state in the country to ban TikTok after Republican Gov. Greg Gianforte signed the bill into law on Wednesday, May 17. The law is set to take effect in January 2024 and is already facing legal challenges.

"To protect Montanans' personal and private data from the Chinese Communist Party, I have banned TikTok in Montana," wrote Gianforte on Twitter.

The ban was quickly criticized by the ACLU amid concerns that the bill infringes on First Amendment rights.
