A New York professor filed a legal claim against Cambridge Analytica seeking information on what the data firm learned about him, CNN reported Sunday.

David Carroll, a professor at the New School’s Parsons School of Design, filed a request on Friday with a British court asking them to order Cambridge Analytica, a data firm used by the Trump campaign, to turn over all the data they’ve collected on the professor, and the source of that data.

The claim was filed the same day Cambridge Analytica was suspended from Facebook after reports it had not fully deleted data it obtained from Cambridge University professor Aleksandr Kogan.

The professor was found to have harvested more than 50 million Facebook profiles from his app, which required a Facebook login, despite only 270,000 having given permission for their data to be harvested, according to a New York Times report Saturday.

About 30 million of the profiles Kogan gave the firm had enough information to create psychographic profiles, the newspaper reported.

CNN reported Sunday that Carroll asked Cambridge Analytica last year to provide the data it had gathered on him. However, the professor claimed the data firm did not disclose how it got all the information.

“If you just go by the topics, they are ranked in a way that demographics alone can’t explain,” he told CNN.

As a result, his legal claim is seeking information on the data they gathered and how they gathered it.

“In particular, I am concerned that I may have been targeted with messages that criticized Secretary Hillary Clinton Hillary Diane Rodham ClintonBiden leads Trump by 36 points nationally among Latinos: poll Democratic super PAC to hit Trump in battleground states over coronavirus deaths Battle lines drawn on precedent in Supreme Court fight MORE with falsified or exaggerated information that negatively affected my sentiment about her candidacy,” he said in a statement to the court.
