The proposed restrictions may lead to a wider ban on the social network in the US

The possibility of a US ban on TikTok just became stronger after a House vote in favour of restricting the social network. Politico reports that representatives voted 336-71 in favour of the National Defense Authorization Act, which includes an amendment banning TikTok from all federal devices.

Colorado Representative Ken Buck proposed the addition after calling TikTok a “serious national security threat.” The company’s data collection could theoretically be used in a cyberattack if shared with the Chinese government, Buck said.

The ban isn’t guaranteed to become law. The Senate still has to pass its version of the Act later this week, and both sides of Congress will have to reconcile their bills before they can receive the President’s signature. It’s possible the ban might be altered or removed in the process.

If the Act does forbid TikTok access, though, it could bring the US closer to a wider ban of the service. Secretary of State Mike Pompeo said officials were “looking at” banning general access to Chinese social media apps, and a federal-level move against TikTok would provide fuel for that case.

For its part, TikTok has repeatedly maintained that it doesn’t share data from its app with the Chinese government. Its parent company ByteDance runs an equivalent app, Douyin, within China’s borders. TikTok has made a point of hiring an American CEO and otherwise distancing itself from ByteDance’s Chinese operations.

Whatever happens, this adds to pressure on the social media giant. India recently banned TikTok and 59 other apps due to its ongoing dispute with China, and it also cited security as a factor. The video sharing service is already poised to lose billions of dollars from the India ban, and it could only get worse if the US follows suit.
