The US Federal Trade Commission (FTC) has opened an inquiry into whether Facebook improperly allowed Cambridge Analytica, a political consulting firm that backed President Trump’s 2016 election campaign, to obtain personal data from 50 million users.

This weekend, a whistleblower informed the Guardian that, in 2014, Cambridge Analytica obtained personal information on millions of US voters, then developed a software program that profiled these citizens to predict voting patterns – and, through micro-targeted ads, influence US citizens’ voting decisions.
