YANKTON, S.D.(WNAX)- South Dakota Senator John Thune spoke to AP history classes at Yankton High School on Friday. He got several questions about social media and government control.

He says there are concerns about China using Tik Tok to spy on Americans.

Thune says the Chinese are working to gather as much US technology as they can.

Thune says while there are bills filed to ban Tik Tok, that could be very difficult.

Thune has co-sponsored several bills attempting to limit the reach of China into US tech companies.
