A firm namely Cambridge Analytica which worked for the Trump camaign during the 2016 elections, was suspended by Facebook for several policy violations.

This was informed by Facebook Vice President and Deputy General Counsel Paul Grewal through his post on Friday night. The post said that the decision was made only after such reports that the firm did not fully delete data given to them by a professor of Cambridge University in violation of Facebook policies.

Grewal also alleged that Dr. Aleksandr Kogan had passed data from his app through Facebook Login, to Strategic Communication Laboratories, which houses Cambridge Analytica.

Whoever used that app allowed Kogan to access information of confidential grade like the city they were living in and also the pages or content they liked.

“Although Kogan gained access to this information in a legitimate way and through the proper channels that governed all developers on Facebook at that time, he did not subsequently abide by our rules. By passing information on to a third party, including SCL/Cambridge Analytica and Christopher Wylie of Eunoia Technologies, he violated our platform policies,” the statement read.

Facebook, according to Grewal, after discovering the violation in 2015, demanded the Cambridge Analytica certify about the data that it has been destroyed which they recieved, and that the company has done so.

“Several days ago, we received reports that, contrary to the certifications we were given, not all data was deleted. We are moving aggressively to determine the accuracy of these claims,” the statement said.

“If true, this is another unacceptable violation of trust and the commitments they made. We are suspending SCL/Cambridge Analytica, Wylie and Kogan from Facebook, pending further information.”

Grewal said that Facebook is very much “committed to vigorously enforcing our policies to protect people’s information.”

“We will take whatever steps are required to see that this happens. We will take legal action if necessary to hold them responsible and accountable for any unlawful behavior,” he added.

The data firm which helped Trump to win, has come under strict scrutiny in the probe into Russian election interference.

Robert Mueller, who is a Special Counsel, reportedly requested all emails from the people working at the firm, who worked with the Trump campaign, and Cambridge Analytica CEO Alexander Nix is reportedly interviewed with the House Intelligence committee.
