In his first appearance before Congress on Thursday, TikTok CEO Shou Chew was grilled by lawmakers who expressed deep skepticism about his company’s attempts to protect US user data and ease concerns about its ties to China.

It was a rare chance for the public to hear from the Chew, who offers very few interviews. Yet his company’s app is among the most popular in America, with more than 150 million active users.

The hearing, which lasted for more than five hours, kicked off with calls from a lawmaker to ban the app in the United States and remained combative throughout. It offered a vivid display of the bipartisan push to crack down on the popular short-form video app and the company’s uphill battle to improve relations with Washington.

Washington Republican Rep. Cathy McMorris Rodgers, the chair of the House Energy and Commerce Committee, opened Thursday’s hearing by telling Shou: “Your platform should be banned.”

“Still, we have heard important concerns about the potential for unwanted foreign access to US data and potential manipulation of the TikTok US ecosystem,” Chew said. “Our approach has never been to dismiss or trivialize any of these concerns. We have addressed them with real action.”
