A Massachusetts judge has ordered Facebook to turn over data requested by Attorney General Maura Healey's office relating to information that may have been improperly shared with Cambridge Analytica, a political consulting and data-mining firm.

Healey joined Boston Public Radio on Friday to discuss the latest development in her office's lawsuit against the social media company.

"We sent subpoenas to investigate the extent to which we believe Facebook has engaged in the systemic collection of our data, and then the sale and use of that data to make money for Facebook, at the expense of our own privacy," she said. "What we still don't know, because Facebook has fought us every step of the way, is all the apps, all the developers that were able to access our data, and what they've done with that."

Cambridge Analytica used data-mining techniques to target ads and political campaigns on social media in the 2016 election.

"This is really important. What these platforms, what Facebook is doing and what they've done, we really need to get to the bottom of it and hold them accountable for the lack of transparency and misuse of our info and data," said Healey. "If they'd only protected our personal data in the same way they're trying to protect their own info from review from our office, and scrutiny of others, we'd probably be in a better place, but that isn't the way Facebook has gone about this."

During the "Ask The Attorney General" segment on Jan. 24, Healey also discussed impeachment, the Roe Act, and took listener calls about myriad consumer concerns.
