Eight TikTok content creators sued the U.S. government on Tuesday, issuing another challenge to the new federal law that would ban the popular social media platform nationwide if its China-based parent company doesn’t sell its stakes within a year.

Attorneys for the creators argue in the lawsuit that the law violates users’ First Amendment rights to free speech, echoing arguments made by TikTok in a separate lawsuit filed by the company last week. The legal challenge could end up before the Supreme Court.

The complaint filed Tuesday comes from a diverse set of content creators, including a Texas-based rancher who has previously appeared in a TikTok commercial, a creator in Arizona who uses TikTok to show his daily life and spread awareness about LGBTQ issues, as well as a business owner who sells skincare products on TikTok Shop, the e-commerce arm of the platform.
