In a series of media interviews Wednesday night, Facebook CEO Mark Zuckerberg finally apologized for the social media giants role in enabling a massive data breach by British firm Cambridge Analytica and said his company is open to the right government regulation.

Zuckerberg gave interviews to a number of media outlets after days of silence on reports that Cambridge Analytica used data obtained through Facebook to help Donald Trump s campaign target users in 2016. Zuckerberg covered a range of other topics, including speaking in front of Congress, possible government regulations and a long-awaited apology.

This is a major breach of trust, and Im really sorry that this happened, Zuckerberg said immediately during an interview with CNN s Laurie Segall. He said the company would soon inform everyone whose data was affected by these rogue apps that have misused users information. He added that hes sure someone is trying to influence the midterm elections .

There are going to be some new tactics that we need to make sure that we observe and get in front of, he said.

Zuckerberg also expressed the need for greater transparency at Facebook and said the company was open to some government regulation akin to that imposed on television and print media.

Im actually not sure we shouldnt be regulated, he told CNN. I think the question more is what is the right regulation rather than should we be regulated.

His avalanche of interviews Wednesday covered quite a few issues that Zuckerberg had been criticized for not addressing in his statement earlier that day.
