Despite the turmoil that continues to surround his company, Mark Zuckerberg has insisted he is still the best person to lead Facebook.
"When you're building something like Facebook which is unprecedented in the world," he said on Wednesday, "there are things that you're going to mess up.
"What I think people should hold us accountable for is if we are learning from our mistakes."
As well as being Facebook's chief executive, Mr Zuckerberg is chairman of the company's board. When asked if his position had been discussed, he replied: "Not that I know of!"
The mere possibility that his leadership is in question is a scenario few would have predicted even a month ago.
But recent reports around improper data gathering by third parties - as well as fake news and propaganda - have prompted some to question Mr Zuckerberg's ability to lead a company that some think has grown beyond his control.
