In an interview with CNN, Brendan Carr, one of the Federal Communications Commission, said Tik Tok should be banned.
He said this is a danger to national security because users use TikTok in the US. TikTok has more than 200 million users in the US.
Some companies in the US have negotiated several times to prevent the Chinese government authorities from accessing US users data on TikTok.
TikTok refuses to commit to cutting off data flows to China.
Carr wrote in a letter to Call and Google in June, asking them to remove the TikTok app from their Play Stores because TikTok was leaking its data to China.
A spokesperson of TikTok said that TikTok supports national data privacy legislation.
