Chinese short-form video-making app TikTok has been banned on mobile devices issued by the U.S. House of Representatives.

The House ordered staff to delete TikTok from any House-issued mobile phones, according to an internal memo seen by NBC News.

“House staff are NOT allowed to download the TikTok app on any House mobile devices. If you have the TikTok app on your House mobile device, you will be contacted to remove it,” read the memo.

Local administrations in 19 U.S. states have already banned TikTok on government issued-devices.

TikTok spokesperson said that the move was a “political signal rather than a practical solution for security concerns.”

Last week, reports surfaced that China-based ByteDance, the parent company of TikTok, accessed data of at least two U.S. journalists and a “small number” of other people connected to them.

In October, TikTok denied that it used specific location data to track certain U.S. individuals, pushing back against a Forbes report that alleged the app was planning on carrying out such monitoring.

In June, TikTok said it started routing U.S. user data through Oracle to appease concerns that China-based employees could access U.S. information.
