There is no evidence provided to back up those accusations.

The members of a House panel questioning Shou Chew, the video app’s C.E.O., appeared unconvinced by his insistence that American user data would be out of reach of the Chinese government. In an often scathing five-hour hearing today, the lawmakers accused TikTok of threatening U.S. national security and harming adolescents.

Republican and Democratic lawmakers repeatedly asked Chew if TikTok — which is owned by Chinese internet giant ByteDance and used by 150 million Americans — was spying on Americans on behalf of the Chinese government. Chew insisted that a program that would store the data of American users on domestic servers would protect their information, but the Biden administration has rejected the proposal.

The popular app has become a battleground in a technological cold war, with American threats of a TikTok ban in some ways mirroring how China has long blocked many American platforms. Hours before Chew testified, China’s commerce ministry said it opposed a sale of the app, potentially narrowing the Biden administration’s options.

Some lawmakers also expressed worries about TikTok’s impact on teenagers. They accused TikTok of building an addictive algorithm that can bombard young people with videos that can put them in dangerous and even lethal situations.
