Why is Montana banning TikTok, and will it work?

The app TikTok is wildly popular, and in some circles, wildly controversial. The state of Montana recently passed legislation that would ban the app in the state. What is it about TikTok that would lead to a state take a drastic action like this? How legitimate are the concerns? Is it even possible to enforce, and what could a move like this lead to? For this conversation, we caught up with Dr. Hilde Van den Bulck, who is a professor and head of the communication department in the College of Arts and Sciences at Drexel University.
