Now she is coming before Congress. > Frances Haugen has come forward with a wide-ranging condemnation of Facebook, buttressed with tens of thousands of pages of internal research documents she secretly copied before leaving her job in Facebook’s civic integrity unit. Haugen also has filed complaints with federal authorities alleging that Facebook’s own research shows that it amplifies hate, misinformation and political unrest, but the company hides what it knows.
