TikTok's fate arrives at Supreme Court in collision of free speech and national security

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. The case is being heard Friday. TikTok says it plans to shut down the social media platform in the U.S. by Jan. 19 unless the Supreme Court strikes down or otherwise delays the effective date of a law aimed at forcing TikTok’s sale by its Chinese parent company. Enforcement of the law would be left to the incoming Trump administration. President-elect Donald Trump has dropped his support for a TikTok ban. The court's decision could come within days.
