Bobby Allyn, NPR; Here are 4 key points from the Facebook whistleblower's testimony on Capitol Hill
"Research shows Facebook coveted young users, despite health concerns.
Of particular concern to lawmakers on Tuesday was Instagram's impact on young children.
Haugen has leaked one Facebook study that found that 13.5 percent of U.K. teen girls in one survey say their suicidal thoughts became more frequent.
Another leaked study found 17% of teen girls say their eating disorders got worse after using Instagram.
About 32% of teen girls said that when they felt bad about their bodies, Instagram made them feel worse, Facebook's researchers found, which was first reported by the Journal.
Sen. Marsha Blackburn, R-Tenn., accused Facebook of intentionally targeting children under age 13 with an "addictive" product — despite the app requiring users be 13 years or older.
"It is clear that Facebook prioritizes profit over the well-being of children and all users," she said.
Blumenthal echoed this concern.
"Facebook exploited teens using powerful algorithms that amplified their insecurities," Blumenthal said. "I hope we will discuss as to whether there is such a thing as a safe algorithm.""
