"We simply have no other choice."
Those are the words used by TikTok in a blogpost Monday as the popular video-sharing app filed a lawsuit to stop the Trump administration from blocking TikTok's usage in the United States.
The company - arguing the proposed ban is a violation of due process.
Trump issued an executive order on August 6th calling for the ban, saying TikTok is a national security threat for its potential to share personal data it collects with China's Communist government.
TikTok said it strongly disagrees with that White House claim, writing that it has "taken extraordinary measures to protect the privacy and security of TikTok's U.S. user data" and that it does not take suing the U.S. government lightly.
TikTok also said the Trump administration violated its constitutional right to due process by banning the company without notice and said the administration was incorrectly using the International Emergency Economic Powers Act to declare a national emergency.
The app, popular with teenagers for sharing dance moves, has been engulfed in the growing dispute between the Trump administration and Chinese-owned tech companies as Beijing and Washington square off.
TikTok is owned by China's ByteDance.
Trump's initial order calling for the TikTok ban was then followed up with another in August, calling for the sale of TikTok's U.S. assets to a U.S. company within 90 days.
ByteDance has been in talks with a number of buyers including Microsoft and Oracle, in a deal that could value TikTok’s U.S. assets as high as $30 billion, sources familiar with the matter told Reuters.
That forced sale is not part of TikTok's lawsuit.
