On Wednesday, the House of Representatives voted overwhelmingly in favour of a bill that could lead to the forced sale or nationwide ban of TikTok in the U.S. To become law, the bill still needs to pass the U.S. Senate, and that’s not guaranteed.

Today, NPR tech correspondent Bobby Allyn on the arguments for and against the bill, how realistic a forced sale or ban would be, and what all this might mean for TikTok’s users.
