Is there a transcript of what kind of questions were asked? I can imagine useful information being gleaned by questions like, "what was the nature of the attack, how were people able to get in, what exactly happened here, how did you store the data, why were you confident it was secure, etc?" That gives you a starting point of what the facts are, what was really experienced. When you are working from a ground zero of zero knowledge (and I bet most of these committee members have zero knowledge, if not all of them), it's good to establish facts of what happened before figuring out solutions.
