Facebook deputy general counsel and Vice President Paul Grewal wrote in a post Friday night that the decision was made after reports that the firm did not fully delete data given to them by a University of Cambridge professor in violation of Facebook policies.

Grewal said Aleksandr Kogan had passed data from his app, which used Facebook login, to Strategic Communication Laboratories (SCL), which houses Cambridge Analytica.

Those using his app allowed Kogan to access information such as the city they were living in and pages or content they liked.

…The data firm has come under scrutiny in the probe into Russia’s election interference.

Special counsel Robert Mueller reportedly requested all emails from employees at the firm who worked with the Trump campaign, and Cambridge Analytica CEO Alexander Nix also reportedly interviewed with the House Intelligence Committee.
