Washington D.C.'s attorney general is suing Facebook over its role in the massive Cambridge Analytica scandal.

AG  Karl Racine filed the lawsuit  Wednesday, claiming the social media giant failed to protect users data by using misleading privacy settings and lax oversight.

Facebook has said  data firm Cambridge Analytica collected information from up to 87 million users without their explicit consent.

All eyes have been on the social media company since the data harvesting scandal.

The  Federal Trade Commission  opened an investigation into Facebook.

The Department of Justice and FBI are also  reportedly investigating  Cambridge Analytica.

And in April, Facebook CEO Mark Zuckerberg  testified before Congress  about the breach and took full responsibility for the leak.

Zuckerberg later appeared before the  European Parliament  to answer questions about Facebook's use of personal data.

But Racine says he wants Facebook to do more than just admit to its failings.

In a statement, the AG says he wants the company to create safeguards to monitor its users' data.

He's also "seeking restitution for consumers, penalties, and costs."
