Exclusive: U.S. opens national security investigation into TikTok - sources

The U.S. government has launched a national security review of TikTok owner Beijing ByteDance Technology Co’s $1 billion acquisition of U.S. social media app Musical.ly, according to three people familiar with the matter.

While the $1 billion acquisition was completed two years ago, U.S. lawmakers have been calling in recent weeks for a national security probe into TikTok, concerned the Chinese company may be censoring politically sensitive content, and raising questions about how it stores personal data.

TikTok has been growing more popular among U.S. teenagers at a time of growing tensions between Washington and Beijing over trade and technology transfers. About 60% of TikTok’s 26.5 million monthly active users in the United States are between the ages of 16 and 24, the company said this year.

The Committee on Foreign Investment in the United States (CFIUS), which reviews deals by foreign acquirers for potential national security risks, has started to review the Musical.ly deal, the sources said. TikTok did not seek clearance from CFIUS when it acquired Musical.ly, they added, which gives the U.S. security panel scope to investigate it now.
