Sheryl Sandberg says Facebook will reveal how Russia targeted U.S. voters

Sheryl Sandberg, Facebook's chief operating officer, said Thursday that the social network would reveal how Russia-linked groups targeted Americans with ads that were designed to disrupt the 2016 presidential election and tip it to Donald Trump.

The Trump campaign used Cambridge Analytica, a firm backed by Trump supporter Robert Mercer, which blended its own database of information on American voters with Facebook to find swing voters or discourage people from voting at all.
