>> Facebook on Wednesday said it may have improperly shared the personal data of 87 million users with Cambridge Analytica. Much more than the previously estimate 50 million. Reuters correspondent David Ingram covers Facebook.>> We are gonna see a compounding effect from this higher estimate of the number of users affected.
This just adds to the likely outrage from lawmakers, from advertisers, from users, from regulators, about the scale of Facebook and the trouble that can come when you have potential privacy violations on that scale.>> CEO Mark Zuckerberg, in a conference call with reporters, vowed to implement stronger controls on users' profile information.
>> It's clear now, that we didn't do enough, we didn't focus enough on preventing abuse, and thinking through how people could use these tools to do harm, as well. We didn't take a broad enough view of what our responsibility is and that was a huge mistake, and it was my mistake.
>> There was a lot of focus during this conference call about whether Mark Zuckerberg was still the right person to be leading the company that he founded.>> Do you still feel like you're the best person to run Facebook moving forward?>> Yes.>> He was asked whether the board had had discussions about him stepping down and he said not that he knew of.
He said that he had not fired anyone as a result of the Cambridge Analytica scandal and did not intend to. So somewhat defiant while at the same time he was apologizing for making mistakes that Facebook made.>> Knowing what I know today, clearly we should've done more and we will going forward.
>> Zuckerberg is set to testify about the leaked profile information next week before the US House Energy and Commerce Committee.
