Trump administration action on risks posed by TikTok likely 'in weeks'

President Donald Trump's administration is studying the national security risks of social media applications including TikTok and WeChat, with action to address the issue expected in the coming weeks, a White House official said on Wednesday.

"There are a number of ... administration officials who are looking at the national security risk as it relates to TikTok, WeChat and other apps that have the potential for national security exposure, specifically as it relates to the gathering of information on American citizens by a foreign adversary," White House Chief of Staff Mark Meadows told reporters en route to Washington from Georgia.

"I don't know that there's any self-imposed deadline in terms of action, but I would say that we're looking at weeks, not months," he added.

TikTok defended its security practices in a statement, saying: "We are fully committed to protecting our users' privacy and security.

"TikTok has an American CEO, a Chief Information Security Officer with decades of U.S. military and law enforcement experience, and a growing U.S. team that works diligently to develop a best-in-class security infrastructure. TikTok U.S. user data is stored in Virginia and Singapore, with strict controls on employee access. These are the facts," the statement said.

WeChat owner Tencent did not immediately respond to a request for comment.

The comments come as TikTok, a popular short video-sharing app owned by Beijing ByteDance Technology Co, finds itself increasingly in the crosshairs of the Trump administration as U.S.-China ties sour over the coronavirus pandemic and Beijing's move to curb freedoms in Hong Kong.

On Wednesday, the New York Times reported the administration was weighing action against Chinese social media services like TikTok under the International Emergency Economic Powers Act, which gives the president broad powers to penalize companies in response to extraordinary threats, citing people familiar with the matter.

But the administration was already looking into the company, after lawmakers called for a probe over concerns it could be censoring politically sensitive content and failing to safely store personal data.

Reuters reported last November that a powerful U.S. government committee known as CFIUS had launched a national security review of Bytedance's $1 billion acquisition of U.S. social media app Musical.ly.

Meadows offered little detail about the mechanisms under consideration to respond to any threats posed by TikTok, but noted that the CFIUS review was perhaps on a parallel tract.

WeChat, a chat app owned by Tencent Holdings Ltd, a Chinese gaming and social media group, has received less scrutiny in Washington.
