Facebook Whistleblower Reveals Identity, Says Firm Chooses "Profit Over Safety"

Frances Haugen, a 37-year-old data scientist from Iowa, has worked for companies including Google and Pinterest.

The whistleblower who shared a trove of Facebook documents alleging the social media giant knew its products were fueling hate and harming children's mental health revealed her identity Sunday in a televised interview, and accused the company of choosing "profit over safety."

Frances Haugen, a 37-year-old data scientist from Iowa, has worked for companies including Google and Pinterest -- but said in an interview with CBS news show "60 Minutes" that Facebook was "substantially worse" than anything she had seen before.

She called for the company to be regulated. "Facebook over and over again has shown it chooses profit over safety. It is subsidizing, it is paying for its profits with our safety," Haugen said.

"The version of Facebook that exists today is tearing our societies apart and causing ethnic violence around the world," she said.
