Facebook is under increasing pressure to withdraw proposed changes that would allow the company to use the names, images, and content of Facebook users for advertising without consent. After EPIC and several privacy groups wrote to the Federal Trade Commission that the changes would violate a 2011 Consent Order, the Commission has opened an investigation. Senator Ed Markey also wrote to the FTC, stating that Facebook's changes "raise[] a number of questions about whether Facebook is improperly altering its privacy policy without proper user consent and, if the changes go into effect, the degree to which Facebook users will lose control over their personal information." Senator Al Franken has called on Facebook to reconsider expansion of its facial recognition activity. In a letter to Mark Zuckerberg, Senator Franken asked "How many face prints does Facebook have?"
