Social Media giant Tiktok has reportedly moved to sue the US government to overturn legislation to ban the app in the country.

According to reports the company filed the lawsuit, in the U.S. Court of Appeals for the D.C. Circuit on Tuesday.

The suit argues that the recently passed Bill, the “Protecting Americans from Foreign Adversary Controlled Applications Act,” violates constitutional protections of free speech, adding that it’s an “unprecedented violation” of the First Amendment.

“For the first time in history, Congress has enacted a law that subjects a single, named speech platform to a permanent, nationwide ban,” TikTok wrote in the lawsuit, “and bars every American from participating in a unique online community with more than 1 billion people worldwide.”

TikTok’s suit also argues that raising national security concerns is an insufficient reason for the restriction of free speech. Concerns it claims the federal government has yet to prove its warrantedness.

Tuesday’s move by TikTok is the latest development in what has been a tug-a-war between the US government and the company to rein in its use in the country. The federal government and dozens of states have already banned the use of TikTok on government-owned devices.

Since 2020, there has been a bi-partisan along with some in the national security community about TikTok’s data collection and security practices, as well as how the app’s video recommendation algorithm works.
