Facebook is reportedly investigating ties between one of its current employees and Cambridge Analytica, the data firm used by the Trump campaign that was recently suspended from the platform.

CNN reported Sunday that the company is looking into Joseph Chancellor, a researcher at Facebook who was previously a director of Global Science Research. The latter company reportedly provided data to Cambridge Analytica.

Facebook suspended Cambridge Analytica from the platform on Friday after reports it had not fully deleted data it obtained through the platform from University of Cambridge professor Aleksandr Kogan.

It's unclear what Chancellor's responsibilities at Global Science Research were, or if he had knowledge of Kogan's data collection practices, CNN reported. But Kogan and Chancellor were both at the University of Cambridge when they set up Global Science Research, according to CNN's report.

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.
