In a collision between free speech and national security, the Supreme Court will hear arguments over the fate of TikTok, a digital age cultural phenomenon that roughly half the U.S. population uses for entertainment and information.

Facing a looming ban in the United States, TikTok's fate will be in the hands of the Supreme Court in a case being argued on Friday that pits free speech rights against national security concerns over the widely used short-video app owned by Chinese company ByteDance.

TikTok will argue its case in front of the Supreme Court this week, but if a law isn't overturned, the app will shut down by January 19.
