TikTok Faces Senate Deadline Over Safety Test Affecting 15 Million U.S. Users
Senators demand TikTok explain a test that disabled a safety feature for 15 million U.S. users, including 16-year-old Chase Nasca, with answers due September 1.
Summary
TechCrunch reported on August 20, 2026, that Senators Marsha Blackburn, Republican of Tennessee, and Richard Blumenthal, Democrat of Connecticut, demanded answers from TikTok CEO Shou Chew and Adam Presser, CEO of its U.S. business, calling the company’s experiment “depraved.” Bloomberg reported that TikTok intentionally withheld an algorithmic safeguard from 10% of U.S. users, or 15 million people, to test whether protection from overwhelming harmful content reduced engagement.
The control group included 16-year-old Chase Nasca, whose feed delivered thousands of videos about sadness, suicide and loneliness before he died by suicide. The senators submitted 13 questions, seeking every employee who knew about the experiment, TikTok’s reason for including minors, and every U.S. algorithm test that disabled or delayed a safety feature. TikTok must respond by September 1 and had not answered TechCrunch’s request for comment.
