The U.S. government should not be in the business of shutting down social media firms on the basis of China-hate. TikTok is no worse (and in fact seems to be far better) than various social media apps from U.S.-based firms. There's a lot of be upset with China about, but TikTok (and drone leader DJI, which also has bipartisan China-hate trying to ban it) are not where Congress should be getting involved. If Congress passes such bans and Biden signs them, there will be major court battles and courts should strike the bans down.
