In the United States, there are growing calls to ban TikTok, owned by China-based company ByteDance, or to pass bipartisan legislation to give President Joe Biden's administration legal authority to seek a ban. Devices owned by the US government were recently banned from having the app installed.

"The House will be moving forward with legislation to protect Americans," McCarthy said on Twitter.

TikTok CEO Shou Zi Chew appeared before a US House Committee for about five hours on Thursday, and lawmakers from both parties grilled him about national security and other concerns involving the app, which has 150 million American users.
