Facebook now faces investigations into its business practices from a variety of federal agencies. Officials have opened inquiries into possible civil and criminal violations of laws related to privacy, corporate governance and discrimination.

Facebook has largely denied wrongdoing in each of the investigations and said it was cooperating with regulators and law enforcement.

Here are the agencies looking into Facebook, and some of the issues involved.

Federal Trade Commission

The top federal watchdog for consumer protection is investigating potential privacy violations by the social network. The inquiry began after reporting by The New York Times on the harvesting of Facebook user data by a political consulting firm, Cambridge Analytica. The investigation centers on whether Facebook broke promises it made in a consent decree in 2011, when it said it would tighten protections of user data and explain clearly to users how it handled sensitive data.

The company could face more than $1 billion in fines and tighter restrictions over its handling of data.
