Social media stocks jumped following an interview from Brendan Carr, one of five commissioners at the Federal Communications Commission (FCC), who told Axios that the Council on Foreign Investment in the US (CFIUS) should take action against the hugely popular (Chinese-owned) short-video app TikTok. 

US lawmakers demanding TikTok banned from US phones is nothing new (see: here & here), but as Axios explained in Carr's interview:

"It's the strongest language Carr has used to date to urge action on TikTok. With more than 200 million downloads in the US alone, the popular app is becoming a form of critical information infrastructure — making the app's ownership by a Chinese parent company a target of growing national security concern."

Even though FCC has no authority to regulate TikTok directly, they can certainly call on Congress to act. 

Axios said TikTok is in discussions with CFIUS about whether it can be divested from ByteDance, a Chinese company, to an American company to remain operational in the US. 

Though, Carr wasn't too optimistic about the future of TikTok in the US. He indicated:

"I don't believe there is a path forward for anything other than a ban." 

He warned there is increasing concern about the high amount of user data flowing back to China and the risk Beijing could influence US politics. He added:

There simply isn't "a world in which you could come up with sufficient protection on the data that you could have sufficient confidence that it's not finding its way back into the hands of the [Chinese Communist Party]."
