Mark Zuckerberg testified in Congress for the second day and told the authorities his personal data was also improperly sold. During the Congressional hearing, the Facebook CEO said a developer sold his personal data to Cambridge Analytica.

Zuckerberg is facing the heat for the recent data scandal where 87 million users’ data was used by Cambridge Analytica. Mr. Zuckerberg also said Facebook plans to sue Cambridge Analytica for the data scandal. The social media giant also plans to sue the Cambridge University professor who provided the firm with the 87 million users’ data.

The CEO also said the company was conducting an audit of Cambridge Analytica to try and retrieve the data. However, Zuckerberg also pointed out if the firm was hosting the data in a foreign country accessing it would be challenging.

During Zuckerberg’s first five hour long testimony on Tuesday, he apologized for the scandal in which 87 million people’s data was collected illegally. The social media CEO was asked about the Russian groups who used Facebook data to rig the 2016 U.S., elections. To this Zuckerberg said his company appointed a special counsel to investigate the alleged meddling.
