TikTok CEO faces Congress and reassures advertisers amidst ban threat.

Shou Zi Chew, CEO of TikTok, is set to testify before Congress on Thursday to defend the app against claims that it is a Chinese spying and propaganda machine. Chew has worked to counter American suspicions with hard logic, telling members of Congress that his company is unaffiliated with the Chinese government and is committed to building a “sunny corner of the internet” for colorful videos and creative speech. However, tensions with the Chinese government and broader anxieties about social media and American children have made TikTok into a political punching bag.
