‘We exploited Facebook to harvest millions of people’s data’: Whistleblower claims analytics firm employed by Trump’s campaign tapped private information of more than 50M users without permission

A data analysis firm employed by President Donald Trump‘s 2016 campaign tapped the Facebook profiles of more than 50 million users without their permission.

The move allowed Cambridge Analytica to capitalize on the private social media activity of a large portion of the U.S. electorate, developing techniques that underpinned its work on President Trump’s campaign in 2016, according to two major reports on Saturday.
