Facebook harms children and weakens democracy - BBC
A former Facebook employee has told US lawmakers that the company's sites and apps "harm children, stoke division and weaken our democracy".
Frances Haugen, a 37-year-old former product manager turned whistleblower, heavily criticised the company at a hearing on Capitol Hill.
Facebook however said Ms Haugen spoke about areas she has no knowledge of.
It comes amid growing scrutiny of the social media giant and increasing calls for its regulation.
