Mark Zuckerberg says Facebook could have done more to prevent misuse

INSKEEP: So you still don't know what the number is.

Zuckerberg is set to testify in Washington on Tuesday and Wednesday.

Sen. John Thune, the Republican chairman of the Senate Commerce Committee said, "I think more than anything else right now most of our members want to express their frustration on behalf of their constituents about what's happened to date and want to hear very seriously about how he intends to fix it".

About 214 million Americans with Facebook profiles do not know whether their data was among the information swept up for Cambridge Analytica.

"People have this idea that we are going to pass omnibus privacy legislation and it is going to be a silver bullet", said Alvaro Bedoya, a former congressional aide who worked on privacy issues for former Senator Al Franken. He faces further grilling from the House Energy and Commerce Committee on Wednesday.

But he acknowledged that "it's clear now that we didn't do enough to prevent these tools from being used for harm as well". "We didn't take a broad enough view of our responsibility, and that was a big mistake", Zuckerberg plans to say.

"This was kind of an app that was being promoted during and around the election, and basically you could download this app, and then you could take this survey about different things, and then they would actually pay you", Epicosity Social Media Coordinator Skyler Crabill said.

Last week, both Zuckerberg and Facebook Chief Operating Officer Sheryl Sandberg were asked this question, and they both said the company was trying to gather as much information as possible before talking about it publicly.

Since 2016, Facebook has faced an array of controversies related to its platform.

Sure enough, Facebook has suspended another data analytics firm, New York-based CubeYou, which also used personality quizzes, while it conducts an audit.

He will also likely face questions about ads and posts placed by Russian operatives, in what U.S. authorities believe was an attempt to influence the United States 2016 election. "How are advertisers or political campaigns using that data to come back onto the Facebook system and seed content to particular users", she added.

Users who were not affected will see a different link highlighting which apps are connected to their Facebook accounts and what data those third parties can see. It took the company a month to respond as the outcry from users and privacy advocates grew.

This whole data scandal has landed Facebook in soup and cost it billions of dollars in market value.

Monday, Facebook began notifying the 87 million users affected by the breach.

Starting Monday, Facebook users were supposed to get alerts that indicate if they are one of up to 87 million people whose private information ended up in the hands of a voter data targeting company, Cambridge Analytica, the same company hired by the Trump campaign and other Republicans.

Zuckerberg will provide testimony and address all matters related to the data incident.

One prominent tech leader, Apple co-founder Steve Wozniak, announced meanwhile that he was leaving the social network.

"Facebook is an idealistic and optimistic company".

To ease the way, Zuckerberg on Monday met some lawmakers privately, listening to their concerns before they will have a chance to interrogate him in public. The 33-year-old's performance in front of Congress could have ramifications for his job security. Zuckerberg has drafted a detailed testimony where he outlined the company's latest initiatives and what it will do to prevent this from ever happening again.

The first hearing kicks off Tuesday at 2:15 pm ET, and Business Insider will be in attendance and covering it live.
