"Is it possible for Facebook to exist without collecting and selling our data?" he said. "I'm aware that there may be, but we are working with them".
"A small number of people who logged into "This Is Your Digital Life" also shared their own News Feed, timeline, posts and messages which may have included posts and messages from you", Facebook said in a missable note.
"Senator, no, I would probably not choose to do that publicly here", Zuckerberg replied.
The number is believed to only be around 1,500, but with Facebook now investigating nearly 10,000 apps it begs the question of how many more examples like this will be found. But he warned that lawmakers should be careful in what they propose.
After resisting previous calls to testify, Zuckerberg agreed to come to Capitol Hill this month after reports surfaced - and the company confirmed - that Cambridge Analytica had gathered Facebook users' data. So could you give me some sort of idea on how you can really, honestly say, it's it's my data when, quite frankly, they may have goods on me, I don't I don't want them to have any information on me.
