Massachusetts Attorney General Maura Healey's office said she wants to understand how the data was used, what policies if any were violated and what the legal implications are.
Cambridge Analytica insisted Saturday that Kogan's company, Global Science Research (GSR) harvested the data.
Facebook announced Friday it had suspended the account of Christopher Wylie, the whistleblower from data firm Cambridge Analytica, shortly before articles were published about the data firm and Facebook.
While Facebook is trying to spin that it didn't have much to do with this (as, in their words, users "knowingly signed up"), it's the biggest personal data breach in the company's history.
"Cambridge Analytica also included extensive questions about Russia's president, Vladimir V. Putin, in surveys it was carrying out in American focus groups in 2014", the Times story says.
Christopher Wylie, who help launch Cambridge Analytica off the ground and developed its voter targeting technology, told the Times that Lukoil was primarily interested in how to craft messages to American social media users.
This, it is claimed, allowed researchers to build personality and psychological profiles on millions of users. "That was the basis that the entire company was built on".
Facebook said that Kogan used an app to gather information from users of the social media platform, which he then broke the company's rules by sharing with Cambridge Analytica. A Cambridge University professor, psychologist Aleksandr Kogan, built the app that collected the user data. "We will take whatever steps are required to see that this happens", Grewal stated in the blog post. That stolen data, according to reports, became the foundation for Cambridge Analytica's efforts to target voters for Donald Trump's 2016 Presidential campaign.
The company was funded by Trump supporter and hedge fund billionaire Robert Mercer, and former Trump senior adviser Stephen Bannon once sat on its board.
The University said that it had received assurances that there was not a conflict between Kogan's academic role and his work for Cambridge Analytica.
It said none of that data was used in the services it provided to Mr Trump's campaign.
In a statement, a Cambridge Analytica spokesman denied any wrongdoing. A good analogy is to say that tn the case of Facebook, these laws only take into account the cybersecurity "walls" surrounding Facebook's databases, because they only recognize the security perimeter above the surface.
Indeed, it appears that Stamos realized that Facebook's decision to dance around the magnitude of the issue was only making matters worse.
"We can condemn this behavior while being accurate in our description of it", he said.
How did this data end up in the hands of the analysis firm?
Another US senator, Mark Warner, said in a statement: "This is more evidence that the online political advertising market is essentially the Wild West".
Reached by ABC News, a spokesperson for Cambridge Analytical defended their work, claiming, "It would be entirely incorrect to attempt to claim that SCL Elections illegally acquired Facebook data". Cambridge Analytica created an effective data mining machine.
Representatives in the United States congress have also called for further regulation of Facebook and some have called for Mr Zuckerberg to appear before a senate committee.
According to Facebook, Cambridge Analytica later certified in 2015 that it had destroyed the information it had received, but the social network said it received reports "several days ago" that not all the data was deleted.
Kogan was not immediately available for comment.
Britain's data protection regulator also said this weekend that it was carrying out the potential illegal acquisition and use of Facebook data.
