The Federal Trade Commission has confirmed that it is investigating Facebook’s privacy practices after it was revealed that the company allowed Cambridge Analytica access to the personal data of some 50 million Facebook users without their expressed consent.

“The FTC takes very seriously recent press reports raising substantial concerns about the privacy practices of Facebook. Today, the FTC is confirming that it has an open non-public investigation into these practices,” the agency said in a statement, after declining to comment last week when Bloomberg reported that an investigation has been opened.
