Instead, Zuckerberg acknowledged that a "breach of trust" had occurred, and added that "We have a responsibility to protect your data, and if we can't then we don't deserve to serve you".
Noting that Facebook officials "have some sense of the different things that we need to get in front of", Zuckerberg said the company staffers are "building technology" and hiring human reviewers to stamp out propaganda and other attacks.
In his Facebook post, after telling how much he cares for everybody and how much serious Facebook is about what's happening, he listed some steps the company plans to take to ensure such incidents don't happen in future.
"In the wake of recent data theft from Facebook, let my stern warning be heard across the Atlantic, far away in California". Cambridge Analytica claims they have already deleted the data and has agreed to a forensic audit by a firm we hired to confirm this. The British Parliament has also summoned him to explain himself to its media committee, while the European Parliament has "invited" him to "clarify before the representatives of 500 million Europeans that personal data is not being used to manipulate democracy". The application then gathered the data of their friends until it gave them access to tens of millions of users.More news: Hoosier unemployment inches lower for February

Zuckerberg said in a statement he has "been working to understand exactly what happened and how to make sure this doesn't happen again".
Lastly, Facebook is expanding its bug bounty program, rewarding more people for reporting any misuses of data by app developers.
UK Information Commissioner Elizabeth Denham first demanded access to Cambridge Analytica's records and data on March 7. However, later in the day, Zuckerberg said, "This was a major breach of trust and I'm really sorry this happened", in an interview on television network CNN.
Worryingly, however, the Facebook CEO also said that he believes someone may be attempting to interfere in the 2018 midterm elections.
Now, politicians in the US and United Kingdom want Zuckerberg to answer for the privacy scandal with thinly veiled threats that governments will crack down.
It was only a matter of time before Zuckerberg emerged.
