Welcome to Ad Age's Wake-Up Call, our daily roundup of advertising, marketing, media and digital news. What people are talking about today: Facebook's Mark Zuckerberg will be in the hot seat today, answering U.S. lawmakers' questions about Facebook's failings. Ad Age's Garett Sloane has a guide about what to expect from two days of congressional hearings about the social network's data privacy scandal. As Sloane writes:
"There is no way Zuckerberg should expect to get away from Washington without answering, 'What did you know and when did you know it?' That's the question that gets to the heart of almost every D.C. scandal, and there are still big questions about the timeline of Facebook's dealings with Cambridge Analytica and why it did not punish its misdeeds sooner."
Zuckerberg's prepared comments, released ahead of time, look like a compilation of talking points/apologies/promises that we've heard a lot lately. One excerpt from his comments to be delivered Wednesday to a committee at the House of Representatives: "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."
