The class-action lawsuit filed this week in California contends data was used to send specific political posts aimed out swaying voters.
John Yanchunis with Morgan and Morgan, one of the lead attorneys in the case says they are seeking compensation for anyone who is affected.
On Wednesday Facebook CEO Mark Zuckerburg posted multiple measures the site now has in place to protect users’ information.
Wednesday, on CNN, Zuckerburg apologized in his first on-camera appearance since the scandal broke.
“We have a basic responsibility to protect people's data, and if we don't do that, then we don't deserve to have the opportunity to serve people," Zuckerburg said.
And he promised to look deeper into the activity of app developers.
"Are they selling the data in a way that people don't want? Are they giving it to someone that they don't have authorization to do?"
Now, members of congress are calling on the Facebook founder to testify under oath. Zuckerburg says he's happy to comply.
Meanwhile, the Federal Trade Commission is investigating whether the site violated the terms of a 2011 agreement about how user data was to be handled.
