JUSTIN FINCH: This morning, Congress seems more determined than ever to ban TikTok, the Chinese-owned social media platform with 150 million users in the US. - It was quite clear from his answers that, in my opinion, that the Chinese Communist Party does have a lot of influence over them or could. JUSTIN FINCH: TikTok's CEO faced five hours of questioning from Democrats and Republicans. - Quite frankly, I don't trust anything that was being said in there about who has access to the data. JUSTIN FINCH: Lawmakers demanding to know whether the platform can protect Americans' data or whether that data could end up in the hands of the Chinese government. - The Chinese Communist Party is able to use this as a tool to manipulate America as a whole. Your platform should be banned. JUSTIN FINCH: CEO Shou Chew insists that the platform has taken steps to protect data, including a so-called firewall. - There are more than 150 million Americans who love our platform. And we know we have a responsibility to protect them. JUSTIN FINCH: He says the plan is to store Americans' data on US soil. But Chew says that firewall won't be in place until later this year. - I have seen no evidence that the Chinese government has access to that data. They have never asked us. We have not provide it. ANNA ESHOO: But you know what? I find that-- I find that actually preposterous. JUSTIN FINCH: It's unclear if yesterday's hearing will translate into any action. The Biden administration has already said it wants TikTok's Chinese parent company to sell its US operations or face a possible ban. Beijing says, it opposes such a sale. A TikTok spokesperson says, "Shou came prepared to answer questions from Congress. But unfortunately, the day was dominated by political grandstanding." In the meantime, one state is taking new action to curb teen's social media use. The Governor of Utah now signed a bill requiring parental permission for children to use social media. It also prohibits kids under 18 from using social media between 10:30 PM and 6:30 AM. It's unclear how the state will enforce those rules. And back here in Washington, bipartisan support for a Senate bill that would call for the regulation or even outright banning of foreign-made technology, like TikTok. Though, there is no timeline as to when a decision might be made.
