Adam Mosseri, head of Instagram, faced withering questions on Capitol Hill about the reports the social media app was aware of the severe mental health impacts it was having on teenage girls. Karen Kornbluh, the director of digital innovation and democracy for the German Marshall Fund, joined Cheddar to discuss the rare show of bipartisan outrage on display at the Senate hearing. "The senators came really loaded for bear on both sides of the aisle," she said. Kornbluh explained how senators like Richard Blumenthal (D-Conn.) set up fake Instagram accounts with teen girl profiles in order to research the effects firsthand.
