The fact that they disclosed it publicly and the market reacted sharply, is the latest indication of rising scrutiny and concern among various government agencies of Facebook's practices.
>> At the heart of the probe, whether Facebook violated a 2011 agreement with the FTC that it had to obtain users' permissions before data about them could be shared beyond the privacy settings they established. The Senate Judiciary Committee on Monday also invited Mark Zuckerberg to testify at a privacy hearing in April.
