On Wednesday, a U.S. resident has sued Facebook and a British-based political consultancy for obtaining data from millions of the social media site’s users without their permission. It's the first complaint of what may be many lawsuits seeking damages over Facebook’s ability to protect user data, and exploitation of the information by data company Cambridge Analytica. The consultancy was hired by President Donald Trump for the 2016 campaign, which improperly accessed information of Facebook users to build detailed profiles on American voters.
