Facebook CEO Mark Zuckerberg has made his first public appearance since the revelations that research company Cambridge Analytica had harvested data from 50 million Facebook users without their permission.

"This was a major breach of trust and I'm really sorry that this happened," Zuckerberg told CNN, reiterating a statement published on his own Facebook page earlier in the day. "We have a basic responsibility to protect people's data, and if we can't do that then we don't deserve to have the opportunity to serve people."
