Mark Zuckerberg says Sorry

Washington, Mar 22: "I'm really sorry that this happened," the Facebook (FB) CEO told to media here on Wednesday.

We have a responsibility to protect your data, and if we can't then we don't deserve to serve you," Zuckerberg said, in his first public comments on the harvesting of Facebook user data by a British firm linked to President Donald Trump's 2016 campaign.

Writing on his Facebook page, Zuckerberg announced new steps to rein in the leakage of data to outside developers and third-party apps, while giving users more control over their information through a special toolbar.

Zuckerberg addressed the scandal publicly through a Facebook post on Wednesday. He wrote that the company made "mistakes" and outlined how it has changed its policies to make sure that user data is protected.

"I wish we'd taken those steps earlier," Zuckerberg told Segall. "That ... is probably the biggest mistake that we made here."
