Congress has posted online Mark Zuckerberg's prepared testimony ahead of a Wednesday hearing. The seven-page statement starts with an apology from Zuckerberg, saying “That was a big mistake. It was my mistake, and I’m sorry” he says that Facebook failed to take a broad enough view of its responsibilities. He continues “I started Facebook, I run it,” and that it is he who is responsible for everything that happens here. It's one of two Capitol Hill appearances for the Facebook Founder and CEO this week. Zuckerberg will be testifying before the US House of Representatives Committee on Energy and Commerce on Wednesday after he faces another hearing in the Senate on Tuesday. The testimony covers familiar issues like Facebook facing questions following reports that research firm Cambridge Analytica improperly gained access to the personal information of as many as 87 million Facebook users and also the Russia-linked Internet Research Agency’s misinformation campaign. Josh Constine at TechCrunch marks that it does offer some new information regarding Russia-linked APT28 hacking group but Facebook confirms that it has detected and shut down accounts related to APT28 over the summer of 2016. This week’s hearing by Zuckerberg will be his first opportunity to address privacy policies before lawmakers as well as making his first appearance in Congress.
