The campaign against Chinese-owned TikTok has reached a new height. The U.S. House of Representatives passed a law banning TikTok on official devices.

In an email on Tuesday, the House Office of the Chief Administrative Officer told representatives and staff that TikTok was no longer allowed on official devices because of security issues. The email recipients were instructed by the CAO to uninstall TikTok from their official devices.

Chief Administrative Officer Catherine Szpindor wrote in an email that House staff are not allowed to download the TikTok app on any House mobile device. Tik Tok can't be used on mobile devices in the house. You will be contacted if you have the TikTok app on your phone.

The app will not be downloaded in the future. ByteDance is the parent company of TikTok.

The policy doesn't apply to personal devices, only to official House devices, according to a spokesman for the CAO.

The CAO sent an email just days after the House passed the omnibus bill, which will now be signed by the president. The ban on TikTok was part of the omnibus bill. The Committee on House Administration gave the CAO the go-ahead to implement a similar policy for the House.

ByteDance, the parent company of TikTok, came under fire last week after it was discovered that four company employees had accessed the TikTok data of U.S.

State and federal lawmakers think TikTok is gathering intel on Americans. TikTok has been partially banned in 19 states. TikTok tried to appease fears by assuring Americans that their user data will be stored in the U.S.
