President Donald Trump's push for the sale of TikTok to a U.S. company marks a major escalation in his battle to keep data on American citizens out of Chinese hands and a move that, if successful, would be nearly impossible to overturn under U.S. law.
Trump's demand has set off a geopolitical tug-of-war, but it has ample precedent. The administration has required at least three previous Chinese investments in U.S. companies to be unwound on national security grounds after they closed. Each involved data security.
Those decisions followed investigations by the Committee on Foreign Investment in the U.S., or Cfius, an interagency panel led by the Treasury Department that reviews acquisitions of American businesses by overseas investors and can recommend the president block and unwind deals to protect national security.
U.S. government decisions to block and unwind deals on national security grounds are all but impossible to overturn in court. The law that governs Cfius investigations says presidential findings "shall not be subject to judicial review." Only one company has ever challenged a Cfius determination and the case was ultimately settled after the federal appeals court in Washington said the company was entitled to see the unclassified information the committee used.
End of Story
"Essentially what the committee and the president decide is the end of the story," said Brian Fleming, a lawyer at Miller & Chevalier who previously worked in the Justice Department's national security division. "They could spend a lot of time and money to litigate but there's an extraordinarily low likelihood of success in challenging something like this,"
Under Trump, Cfius has become more aggressive toward Chinese investment and is using new authority granted by Congress in 2018 to scrutinize deals, particularly those involving companies like TikTok that collect data on Americans. Cfius typically reviews acquisitions before they close but it can also look back at completed deals when companies never filed for approval from the panel.
Cfius's investigation of TikTok stems from the 2017 purchase by China's ByteDance Ltd. of Musical.ly, an app which did business in the U.S and was later folded into TikTok. Now, Microsoft is in talks to buy TikTok's operations in the U.S., Canada, Australia and New Zealand, and the company said it's aiming to complete the deal no later than Sept. 15.
"It sounds like Microsoft is along the way of doing something," Trump told reporters Tuesday.
"I don't blame them. It's a great company," he said of TikTok. "It's really a great company, but we cannot take the security risk."
