Mom blames Instagram for her teen daughters' death

Julianna Arnold says her 17-year-old daughter died after she met an older man on Instagram who sold her pills laced with fentanyl. She now runs a non-profit for parents who say they lost their children because of social media. She says this week's trial against Meta, YouTube and TikTok is a crucial moment for accountability after years of raising alarms about the risks of social media for young people.
