One of the FCC's five commissioners is urging Congress to prohibit TikTok due to fears that user data could end up in the hands of China's government.
"I don't believe there is any other way ahead than a ban," FCC Commissioner Brendan Carr said in a report released Tuesday.
China-based ByteDance owns TikTok. Carr, appointed by Trump, asked Apple and Google to remove TikTok from their app stores on data harvesting fears.
TikTok has tens of millions of users in the United States, and its popularity is growing as other social media platforms struggle to maintain robust growth.
TikTok has been in talks with the Committee on Foreign Investment in the United States in order to separate from ByteDance and become its own company.
Skepticism about the app's ties to the Chinese government has grown after the Trump administration's failed attempt to ban the social media platform in 2020.
Senate Republicans wrote to Treasury Secretary Janet Yellen this year about TikTok, alleging the Biden administration wasn't taking the national security threat seriously.
A spokesperson for TikTok claimed that the FCC commissioner plays no part in the current negotiations between the company and the United States government.
A TikTok representative stated, "We're optimistic we'll strike an arrangement with the U.S. that will satisfy any reasonable national security concerns."
