The Connecticut attorney general is demanding answers from Facebook following reports that the data research firm Cambridge Analytica obtained information on 50 million users without their consent.

"News reports that personal user information from Facebook profiles was provided to third parties without user consent are concerning and raise serious questions about how this happened in the specific situation involving Cambridge Analytica and about Facebook's policies and practices more generally,” Attorney General George Jepsen said in a statement.
