The funny aspect to me is that the senators pushing to "ban TikTok" are the same senators pushing for an "open App Store" bill. But I don't see how you can have it both ways.
Sure you can sanction TikTok. Are you going to jail every middle schooler who "does business" with them by downloading the app from unofficial sources?
Or perhaps you want to force ISPs to drop connections to TikTok servers?
