So starting this Sunday, the mobile apps TikTok and WeChat will be banned from U.S. app stores. That was the announcement from the U.S. Commerce Department today. The Chinese-owned apps have been the target of the Trump administration. They say the apps collect data from American users that could be accessed by the Chinese government. A sale of TikTok has been in the works, but so far, no deal has been finalized. And let's turn to NPR's Bobby Allyn, who's been following this story. Good morning, Bobby.
