Cambridge Analytica, the data firm used by the Trump campaign, pushed back Monday against reports that it obtained the private information of millions of Facebook users without their permission and failed to destroy it.

The company said in a statement it “strongly denies” reports that it used data harvested from 50 million Facebook profiles for the Trump campaign, and said it deleted all the Facebook data it had accumulated.

Facebook suspended the firm from its platform on Friday, saying it did not fully delete data given to it by Aleksandr Kogan, a University of Cambridge professor.

Kogan reportedly obtained the information from an app he created, which used a Facebook login.

The New York Times reported that 30 million of the profiles provided by Kogan contained enough information for the firm to create psychographic profiles.
