Pres. Biden signs provision that could ban TikTok in the U.S.

Congress has long had national security concerns about the Chinese-owned social media app TikTok, but has not succeeded in banning the platform from American app stores. A new law requires TikTok's Beijing-based parent company ByteDance to sell its stake within 9 months or face a nationwide ban. Now, TikTok's CEO is pushing back and promising a legal challenge. KTVU's Heather Holmes and Alex Savidge discuss the implications of the bill with Nadine Farid Johnson, Policy Director at the Knight First Amendment Institute at Columbia University.
