Law firm Morgan and Morgan said Wednesday it has filed the first class-action lawsuit from the data breach of more than 50 million users on Facebook by Cambridge Analytica.

  • Morgan and Morgan files suit in Facebook breach by Cambridge Analytica
  • Class-action suit filed in Northern District of California 
  • John Yanchunis says firm 'waged psychological warfare'
  • READ COMPLAINT: Price v. Facebook, Inc., Cambridge Analytica

The suit, Price v. Facebook, Inc. and Cambridge Analytica, was filed by attorney John Yanchunis in the Northern District of California on behalf of plaintiff Lauren Price and all other Facebook users affected by the data mining.

Yanchunis released the following statement Wednesday in a news release:

“The recent disclosure of the violation of the privacy rights of 50 million consumers who use and trusted Facebook represents yet another troubling example of a company’s failure to maintain the security of information consumers provided – despite its representations to consumers that they have a choice to allow who can access their information through privacy settings.”

He continued by alleging that Cambridge Analytica waged “psychological warfare” against unsuspecting and non-consenting Facebook users.

Cambridge Analytica is a political consulting firm that worked with President Donald Trump’s 2016 presidential campaign.

The research firm Cambridge Analytica was found to have used Facebook to gather data about tens of millions of Americans. It then transferred the data to an analytics company that would eventually work for President Donald Trump's 2016 campaign.

Critics have accused the firm of illegally mining data to target Facebook users with campaign ads.

The firm denies using any of the data to target voters.

Yanchunis said it's “alarming” that Facebook executives reportedly knew of the breach and chose not to say anything until March 16, when the company announced it was suspending Cambridge Analytica.

Facebook shares have taken a huge hit this week, after the Cambridge Analytica scandal broke.

Facebook founder and CEO Mark Zuckerberg gave his first on-camera interview to CNN on Wednesday in the aftermath of the scandal. He apologized for what he called a “major breach of trust.”

Now, members of Congress are calling on Zuckerberg to testify under oath.

“The short answer is, I'm happy to if it's the right thing to do,” he told CNN.
