TikTok and its U.S. employees are planning to take President Donald Trump's administration to court over his sweeping order to ban the popular video app, according to a lawyer preparing one of the lawsuits.

The employees' legal challenge to Trump's executive order will be separate from a pending lawsuit from the company that owns the app, though both will argue that the order is unconstitutional, said Mike Godwin, an internet policy lawyer representing the employees.

Trump last week ordered sweeping but vague bans on dealings with the Chinese owners of TikTok and messaging app WeChat, saying they are a threat to U.S. national security, foreign policy and the economy. The TikTok order would take effect in September, but it remains unclear what it will mean for the apps' 100 million U.S. users, many of them teenagers or young adults who use it to post and watch short-form videos.

It's also unclear if it will make it illegal for TikTok to pay its roughly 1,500 workers in the U.S., which is why some of them came to Godwin for help, he said. The order would prohibit “any transaction by any person” with TikTok and its Chinese parent company ByteDance.

“Employees correctly recognize that their jobs are in danger and their payment is in danger right now,” Godwin said.

TikTok didn’t return multiple requests for comment this week. It said in a statement Friday that it was “shocked by the recent Executive Order, which was issued without any due process.”

The Fifth and 14th Amendments to the U.S. Constitution safeguard life, liberty and property from arbitrary government action lacking “due process of law.”

Microsoft is in talks to buy parts of TikTok, in a potential sale that’s being forced under Trump’s threat of a ban.

TikTok said it spent nearly a year trying to engage in “good faith” with the U.S. government to address its concerns.

“What we encountered instead was that the Administration paid no attention to facts, dictated terms of an agreement without going through standard legal processes, and tried to insert itself into negotiations between private businesses,” the company’s statement said.

The White House didn’t immediately return a request for comment Thursday on the pending challenges.

Godwin said he was retained by Patrick Ryan, who joined TikTok from Google earlier this year as a technical program manager. Ryan posted a public fundraising pitch on GoFundMe this week to raise money for attorneys who can “fight this unconstitutional taking.”

“This is unprecedented,” Ryan wrote. “And it’s frankly really uncool.”

Unlike other Chinese tech companies targeted by Trump, such as telecom giant Huawei, TikTok's widespread popularity among Americans adds a layer of complexity to its legal and political challenges. The looming ban has annoyed TikTok users, some of them Trump supporters like Pam Graef of Metairie, Louisiana.

The 53-year-old fitness instructor found nearly instant TikTok fame after downloading the app this summer and posting a video of herself dancing frenetically in a kitchen as someone pretending to be her embarrassed daughter shouts that she's doing it wrong. The video has nearly 3.5 million views.

“I don’t want it to be banned. It’s just a blast,” Graef said. “It’s a way for me to promote my virtual training and virtual classes.”

She said Trump won’t lose her vote over this, but she doesn’t understand all the fuss about the app’s Chinese ownership. “What are they gaining by spying on us?” Graef said. “We’re just doing stupid videos and having fun.”

The company said last week the way it collects data is typical for thousands of mobile apps. “We have made clear that TikTok has never shared user data with the Chinese government, nor censored content at its request,” it said.

Godwin said the employees' legal challenge will be focused on worker rights, not on the national security claims underlying Trump's order.

The civil rights lawyer, known in early internet culture for coining “Godwin's law,” which posits that all online debates will eventually devolve into the use of Nazi analogies, said employees can't afford to wait.

“We have to proceed very quickly,” he said Thursday. "If we wait around for the order to be enforced, which it will be on September 20, then the workers will lose their chances to be paid.”
