A Senate subcommittee on Tuesday heard from a whistleblower who claims Facebook manipulated content it knew was harmful to young users, a day after the social media giant experienced an apparently unrelated massive outage.
Frances Haugen, who revealed her identity during a Sunday interview on CBS' "60 Minutes," has been cooperating with a Senate Commerce subcommittee as part of its ongoing efforts to assess potential regulation of the platform. Haugen told lawmakers on Tuesday about documentation she said show the company -- and CEO Mark Zuckerberg -- intentionally ignored proof of its potentially harmful impact on users.
Facebook has publicly disputed Haugen's claims.
