The US Federal Trade Commission will investigate Facebook over how private data on millions of users was given to Cambridge Analytica.<\/p>\n
The social network has been criticised for letting the analysis firm scoop up data on 50 million users.<\/p>\n
The information is believed to have been used to help Donald Trump’s 2016 campaign for US president.<\/p>\n
The FTC said its probe would determine whether Facebook had “failed” to protect users’ privacy.<\/p>\n
News of the FTC probe, which former FTC officials say could trigger fines in the trillions of dollars – sent shares down 6.5% in afternoon trading in New York before they recovered slightly.<\/p>\n
Tom Pahl, acting director of the FTC’s Bureau of Consumer Protection, said it took the reports about user data going astray “very seriously”.<\/p>\n
He said the FTC regularly took “enforcement action” against firms that caused substantial injury to consumers by breaking laws that govern how personal information should be kept safe.<\/p>\n
Facebook is required by law to notify users and get their permission before data is shared beyond their preferred privacy settings in what is known as the “consent decree”.<\/p>\n
David Vladeck, the former director of the FTC’s Bureau of Consumer Protection, said that the penalty for each violation of the consent decree is $40,000.<\/p>\n
If the data of 50 million people were indeed compromised, the social network’s financial exposure to fines could run into trillions of dollars, Mr Vladeck told the Washington Post<\/a>.<\/p>\n
