"Senator, we consider ourselves to be a platform for ideas", Zuckerberg replied.
On April 5, the social media giant, however, revealed that the data of as many as 87 million users was improperly shared with British political consultancy Cambridge Analytica, far greater than the 50 million previously estimated. Zuckerberg said he had never seen that text before. You can also follow Zuckerberg's testimony in the live blog below.
The shares fell steeply last month after it came to light that millions of users' personal information was harvested from Facebook by Cambridge Analytica, a political consultancy that has counted US President Donald Trump's election campaign among its clients.
"Has anyone been fired from the app review team?" Not his thing, this sort of public theatre of inquiry.
On Tuesday, the Facebook CEO testified in front of a rare US Senate joint committee hearing.
But the 33-year-old internet mogul managed to deflect any specific promises to support any congressional regulation of the world's largest social media network and other US internet companies. It seems Zuckerberg needed some extra padding for his chair.

Kennedy told the laughing hearing room that Facebook was covering their "rear end" with the user agreement before bluntly stating, "I am going to suggest to you that you go back home and rewrite it..." How do you make money? All you have to do is download the Domino's Alexa Skill and link your account using the pizza-maker's app. Then, when you're hungry, just say "Alexa, open Domino's" to launch the skill. Assert that Facebook started as an idealistic and optimistic company. Now you can just say "Alexa, how is traffic?" or "Alexa, what's my commute?" and Amazon will tell you what to expect from your drive. That was something even Dimon couldn't prevent.
"What about Palmer Luckey?"
This mention of affordability could suggest a move towards a YouTube-style system, with an ad-driven version available for free, and an ad-free subscription service for users who are willing to pay.
