The Trump administration has been weighing whether to direct China-based ByteDance Ltd. to divest its stake in TikTok’s U.S. operations, according to several people familiar with the issue. The U.S. has been investigating potential national security risks due to the Chinese company’s control of the app.

While the administration was prepared to announce an order as soon as Friday, according to three people familiar with the matter, another person said later that the decision was on hold, pending further review by President Donald Trump. All of the people asked not to be identified because the deliberations are private.

Spokespeople for Microsoft and TikTok declined to comment on any potential talks. The software company’s interest in the app was reported earlier by Fox Business Network.

“We are looking at TikTok. We may be banning TikTok,” Trump told reporters Friday at the White House. “We are looking at a lot of alternatives with respect to TikTok.”

Any transaction could face regulatory hurdles. ByteDance bought Musical.ly Inc. in 2017 and merged it with TikTok, creating a social-media hit in the U.S — the first Chinese app to make such inroads. As TikTok became more popular, U.S. officials grew concerned about the potential for the Chinese government to use the app to gain data on U.S. citizens.

The Committee on Foreign Investment in the U.S. began a review in 2019 of the Musical.ly purchase. In recent years, CFIUS, which investigates overseas acquisitions of U.S. businesses, has taken a much more aggressive role in reviewing and approving deals that may threaten national security. It can recommend that the president block or unwind transactions.

It’s also possible that other potential buyers could come forward, said another person familiar with the discussions. Microsoft’s industry peers — Facebook Inc., Apple Inc., Amazon.com Inc. and Alphabet Inc. — fit the profile of potential suitors, though all are under antitrust scrutiny from U.S. regulators, which would likely complicate a deal.

A purchase of TikTok would represent a huge coup for Microsoft, which would gain a popular consumer app that has won over young people with a steady diet of dance videos, lip-syncing clips and viral memes. The company has dabbled in social-media investments in the past, but hasn’t developed a popular service of its own in the lucrative sector. Microsoft acquired the LinkedIn job-hunting and corporate networking company for $26.2 billion in 2016.

Microsoft can point to one acquisition that came with a massive existing community of users that has increased under its ownership — the 2014 deal for Minecraft, the best-selling video game ever.

Other purchases of popular services have gone less well. The 2011 pickup of Skype led to several years of stagnation for the voice-calling service and Microsoft fell behind newer products in the category. Outside of Xbox, the company hasn’t focused on younger consumers. A TikTok deal could change that, though, and give Microsoft “a crown jewel on the consumer social media front,” Dan Ives, an analyst at Wedbush Securities, wrote in a note to investors Friday.

TikTok has repeatedly rejected accusations that it feeds user data to China or is beholden to Beijing, even though ByteDance is based there. TikTok now has a U.S.-based chief executive officer and ByteDance has considered making other organizational changes to satisfy U.S. authorities.

On Thursday, U.S. Senators Josh Hawley, a Missouri Republican, and Richard Blumenthal, a Connecticut Democrat, wrote the Justice Department asking for an investigation of whether TikTok has violated the constitutional rights of Americans by sharing private information with the Chinese government.

A deal with Microsoft could potentially help extract ByteDance from the political war between the U.S. and China.

U.S. Senator Marco Rubio, a Florida Republican and member of the Senate’s Select Committee on Intelligence, applauded the idea of a TikTok sale. “In its current form, TikTok represents a potential threat to personal privacy and our national security,” Rubio said in a statement. “We must do more than simply remove ByteDance from the equation. Moving forward, we must establish a framework of standards that must be met before a high-risk, foreign-based app is allowed to operate on American telecommunications networks and devices.”
