The positive outcome came after a massive 10 hours of questioning over the span of two days.
With questions still swirling about how foreign entities use platforms like Facebook and Twitter to spread fake news and sow division, and how these networks handle user data, it's curious Congressional Republicans would spend so much time questioning Zuckerberg about two vloggers.
"We have not seen wild changes in behavior", the Wall Street Journal quoted Everson as saying, "with people saying I'm not going to share any data with Facebook anymore". This is not a term that Facebook uses, officially - or at least it's not one they'll admit to using publicly.
After a long pause and an embarrassed grin he answered "umm.no!" "More important, the pieces of data that I found objectionable, like the record of people I had unfriended, could not be removed from Facebook, either".
Rep. Raul Ruiz of California explained that Facebook's recent crises, despite the company operating under an FTC decree, may mean that the federal government should create a regulatory body that oversees how consumer data is collected and used. Again, Mr Zuckerberg appeared uncomfortable.
New Mexico's representative Ben Ray Lujan asked Zuckerberg if Facebook maintains a detailed profile of people who never signed up for Facebook.
It felt as though the company made a calculated decision to deflect rather than talk openly about the scope of Facebook data collection and its data-based ad system. "Right there. Not buried in the settings somewhere but right there", Zuckerberg said.
And last week the European Union had said that its justice commissioner, Vera Jourova, would hold phone talks with Facebook's Chief Operating Officer Sheryl Sandberg to discuss what the company is doing to address the breach, which may have affected 87 million people around the world. "All of that", Hoffman said.
The university fired straight back.
The social media platform announced the action against the company on Monday. And as for Dr Kogan, the university had written to Facebook about its allegations against him but had not received a reply.
"It certainly doesn't feel like that to me", Zuckerberg responded, eliciting a few snickers from the audience.
Dr Kogan and the Cambridge Psychometrics Centre are in dispute over whether a row over his personality app - and the involvement of the centre's academics - was about ethics or money. "I promise to do better for you", he wrote. That's also what makes Facebook so terrible: It knows everything about you.
"If we find someone that improperly used data, we're going to ban them from our platform and tell everyone affected", he said.
Cambridge Analytica compromised personal information of approximately 87 million users, half a million of whom were from India.
