Mark Zuckerberg is finally holding a press conference. Sorta.

The Facebook co-founder and CEO is holding a conference call Wednesday to discuss user’s privacy. 

He acknowledged that Facebook is now facing two central questions: “Can we get our systems under control and second, can we make sure that our systems aren’t used to undermine democracy,” Zuckerberg said

“It’s not enough to give people a voice, we have to make sure that people are not using that voice to spread disinformation,” he added. 

And, specifically, he acknowledged that Facebook has “to ensure that everyone in our ecosystem protects people’s information.”

Zuckerberg’s comments come after one of his lieutenants, Facebook’s CTO Mike Schroepfer, said in a blog post that the number of people whose profiles were improperly handed to Cambridge Analytica was much higher than originally thought.

Facebook said data from 87 million Facebook users appears to have been improperly shared with Cambridge Analytica, a more than 50 percent increase from the 50 million people estimated by earlier reports.

Zuckerberg said, in response to a question from CNET, that the company waited to announce this number until Wednesday because he wanted to get a “full understanding” and “give you the complete picture.” He said Facebook wanted to figure out the maximum number of people who may have been affected by the rogue app Facebook said was created by a lecturer at University of Cambridge to collect profile information of millions of users and then hand them to  data analytics firm Cambridge Analytica.
