Data misuse: Facebook's problems are my mistake, says Mark Zuckerberg

Facebook chief Mark Zuckerberg says he accepts responsibility for the social network's failure to protect private data and prevent manipulation of the platform, according to testimony released today on the eve of his first Congressional appearance.

"We didn't take a broad enough view of our responsibility, and that was a big mistake. It was my mistake, and I'm sorry," Zuckerberg said in his written testimony released by a House of Representatives panel.

"I started Facebook, I run it, and I'm responsible for what happens here."

Zuckerberg will testify before senators on Tuesday and a House panel on Wednesday amid a firestorm over the hijacking of data on millions of Facebook users by the British firm Cambridge Analytica, which worked with Donald Trump's campaign.
