"I think a lot of risks that are pointed out are hypothetical and theoretical risks," Chew responded. "I have not seen any evidence."

"I'm eagerly awaiting discussions where we talk about evidence," he added. "And we then can address the concerns that are being raised."

TikTok has not shared U.S. user data with the Chinese government, nor would it comply if asked to do so, Chew previously said.

Rep. Earl Carter, R-Ga., asked Chew about dangerous TikTok challenge videos such as the “blackout challenge,” which critics say encourages users to strangle themselves.

TikTok is facing several lawsuits from parents who say their children died attempting the blackout challenge. The company has blocked searches for #blackoutchallenge, The Washington Post reported.

“Why is it that TikTok consistently fails to identify and moderate these kinds of harmful videos?” Carter asked. “Why is it that you can’t control this?”

Chew replied, “This is a real industry challenge and we’re working very hard.”

“We’re not talking about the industry,” Carter replied back. “We’re talking about TikTok.”

Rep. Kat Cammack showed a TikTok video of an animated gun shooting bullets that appeared to target Rep. McMorris Rodgers, the committee chair.

"Your own community guidelines state that you have a firm stance against enabling violence on or off TikTok," Cammack said when she revealed the video. "This video has been up for 41 days."

The video was taken down during the hearing, Chew confirmed when the hearing resumed after a short break.

"You've said repeatedly that there is no threat, that this is a platform for entertainment and for fun," Cammack said, pointing her finger at Chew. "Why, if you had nothing to hide, would you need to downplay the association with ByteDance and China?"

Chew replied: "Congresswoman, I have not seen that memo."

"You cannot answer that question, Mr. Chew," Cammack said.
