NEW YORK -- Video app TikTok is suing the Trump Administration over its efforts to ban the popular Chinese-owned service over national-security concerns.

TikTok, which is owned by China's ByteDance, insisted Monday that it is not a national-security threat and that the government is acting to 鈥渇urther the president's anti-China political campaign.鈥 The company said the government is acting without evidence for its allegations or due process. It filed suit Monday in federal court in California against the Commerce Department, U.S. President Donald Trump and Commerce Secretary Wilbur Ross, saying that it sought to prevent the government from 鈥渋mpermissibly banning鈥 TikTok by overturning President Donald Trump's executive order.

Trump issued two orders in August. The first, on Aug. 6, imposed a sweeping but unspecified ban on any鈥渢ransaction鈥 with ByteDance, to take effect by Sept. 20. A week later, he ordered ByteDance to sell U.S. TikTok assets within 90 days. TikTok's lawsuit isn't fighting the sell order.

In its complaint, TikTok said that while the full scope of the Aug. 6 ban order remains unclear until the Commerce Department fleshes it out, the order still poses 鈥渁n existential threat to TikTok's U.S. business.鈥 It said it would move to block action by the Commerce Department once it issues rules.

The Commerce Department and White House did not immediately reply to requests for comment.

Over past year, TikTok has tried to put distance between its app, which it says has 100 million U.S. users, and its Chinese owners. It installed a former top Disney executive as its American CEO and named two other Americans chief security officer and general counsel. TikTok has also said it is willing to sell its U.S. operations and has held talks with Microsoft with to buy parts of its English-language app. Other companies and investors have reportedly expressed interest as well.

Both Republican and Democratic lawmakers have shared concerns about TikTok that ranged from its vulnerability to censorship and misinformation campaigns to the safety of user data and children's privacy. But the administration has provided no specific evidence that TikTok has made U.S. users' data available to the Chinese government. The Trump administration has ratcheted up tensions with China over trade and tech security issues; the president has also blamed China for the global coronavirus pandemic. His administration has sought to hobble Chinese telecom equipment maker Huawei and the Chinese messaging app WeChat.

U.S. officials point to the hypothetical threat that lies in the Chinese government's ability to demand co-operation from Chinese companies. TikTok says it has not shared U.S. user data with the Chinese government and would not do so, and that it does not censor videos at the request of Chinese authorities.

In its complaint, TikTok said that it has protected U.S. user data by storing it in the U.S. and Singapore, not China. It said it has also set up 鈥渟oftware barriers鈥 to ensure that TikTok segregates its U.S. user data from other ByteDance products.

The company says Trump's Aug. 6 order violated TikTok's Fifth Amendment due-process rights by giving it no 鈥渘otice or opportunity to be heard.鈥 It claims that the order is not based on a genuine national emergency and the administration hasn't proven that TikTok's activities meet the legal standard of 鈥渁n unusual and extraordinary threat鈥 required by the International Emergency Economic Powers Act, which Trump cited as one of the bases for his order.

Getting a court to overturn the government's determination that TikTok is a national-security threat would be difficult, legal experts said. That true even though the Trump administration is 鈥減ushing authority in places it's never been used before,鈥 said Paul Marquardt, a foreign-investment review lawyer with Cleary Gottlieb in Washington.

Still, the administration has 鈥渟ignificant discretion鈥 on national security, said Christian Davis, a Washington lawyer with Akin Gump whose practice focuses on foreign investment and international trade. Due-process claims might be easier to argue, Davis said, but those issues could be 鈥渃ured鈥 with a modification of the order.

TikTok has grown rapidly in the past two years, racking up nearly 700 million global users as of July 2020, the company said in its complaint. That has drawn the attention of officials in the U.S. as well as in other countries - India has also cracked down on TikTok - as well as U.S. competitors. Facebook recently rolled out a TikTok copycat feature in its Instagram app and its CEO Mark Zuckerberg has publicly criticized TikTok.
