A Maryland woman has sued Facebook and Cambridge Analytica alleging improper use of her personal information to create ads during the 2016 presidential election.

In a lawsuit filed Wednesday, Lauren Price sued the companies over “the absolute disregard with which Defendants have chosen to treat Plaintiff’s Personal Information,” BuzzFeed reported.

Cambridge Analytica, a data firm used by President Trump Donald John TrumpBiden leads Trump by 36 points nationally among Latinos: poll Trump dismisses climate change role in fires, says Newsom needs to manage forest better Jimmy Kimmel hits Trump for rallies while hosting Emmy Awards MORE's campaign, reportedly collected data on nearly 50 million Facebook users and then used it for voter targeting.

“Facebook, for its part, knew this improper data aggregation was occurring and failed to stop it,” according to a complaint filed in federal court in northern California.

Price is looking to pursue the class action lawsuit against the companies for “failing to protect the privacy of its consumers,” her attorney John Yanchunis told BuzzFeed News.

“I find this reprehensible,” Yanchunis said.

Former Cambridge Analytica researcher Aleksandr Kogan blew the whistle this week about the millions of records the U.K-based company pledged to delete but didn’t.
