Instagram’s creator conference in June was supposed to celebrate its commitment to influencers. But one marquee interview has come back to bite Instagram head Adam Mosseri. 

At a Senate hearing Wednesday, Senator ​​Marsha Blackburn (R-Tenn.) used Mosseri’s video exchange with Instagram and YouTube star JoJo Siwa to make the point that Instagram-parent Meta Platforms was not doing enough to protect young people on its apps.

To recap: During Mosseri’s June talk with Siwa, the teen influencer revealed she had been on Instagram since she was five years old, or far younger than the required age of 13. That confession prompted Mosseri to smile and say, “I don’t want to hear that.”
