Rep. Mike Turner, R-Ohio, former chairman of the House Intelligence Committee, said on Sunday that TikTok remains a national security threat and he hopes President-elect Trump can reaches a deal that leads to China-based ByteDance selling its stake in the app.

"Let's be clear, TikTok is absolutely a national security threat," Turner said on "Face the Nation."

Turner said TikTok's "access to data and its ability to use itself as a propaganda tool" make it a threat to the U.S.

"The Supreme Court upheld this. It remains a national security threat. And because of that, the United States Congress, the law - that is the law of the land says that ByteDance need to divest itself," Turner said. "Now, the only thing that would protect the United States, and protect our citizens, is divestiture."

Trump said an executive order extending the time TikTok has to comply with the law by 90 days.

"Elon Musk has said something very interesting. He has said, you know, of course he's noted that Twitter, his X, does not have access to China. And that's sort of an admission by China as to what they're doing with TikTok. They won't let Twitter or X in, almost an admission as to what they're doing," he said.

"Also, you know, ByteDance have said, well, we don't sell it. Another admission that it's really not a business. This is a propaganda tool. It is an access to data," he added.

Turner said he hopes Trump reaches an agreement with TikTok that results in the sale of the app to a company outside of China.

"We certainly hope that he gets a deal that recognizes the issue of national security," he said. "There is no role in which they can remain active in which China can have access to this data."
