Facebook CEO Mark Zuckerberg has been testifying before U.S. lawmakers in an attempt to shake off his firm's biggest privacy scandal to date. <br />He says he's responsible and he's sorry for what happened.<br />Ro Aram has more. <br /> The once press shy Zuckerberg seemed calm and collected, at least for now, as he faced a barage of questions on a range of issues, including Facebook's handling of alleged Russian election meddling and hate speech.<br />But the main and biggest issue by far was consumer privacy. <br />Senators wanted to know how Cambridge Analytica - a British consultancy firm linked to the Trump campaign - harvested the personal data of 87 million users.<br />Zuckerberg started the hearing by apologizing for that incident….<br /><br /> "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. I started Facebook, I run it, and I'm responsible for what happens here."<br /><br /> The Facebook chief explained that an app developer, Aleksandr Kogan, got users' permission to use their data for a quiz app, but breached the terms of service by selling that information to Cambridge Analytica.<br />Senator Bill Nelson asked why users were not notified of the sale of their data and this was Zuckerberg's answer…<br /><br /> "Senator, when we heard back from Cambridge Analytica that they had told us that they weren't using the data and had deleted it, we considered it a closed case. In retrospect, that was clearly a mistake. We shouldn't have taken their word for it and we've updated our policies in how we're going to operate the company to make sure that we don't make that mistake again."<br /><br />Zuckerberg is not only trying to restore public trust in his company but also to fend off possible regulations that some lawmakers have floated.<br /> He's scheduled to testify again on Wednesday before the House Energy and Commerce Committee.<br />Ro Aram, Arirang News. <br />
