Each time we start an examination, we first determine who we think may have information pertaining to what we're trying to review. We make a list of people and organizations and we write a very clear letter to them. The letter makes it very clear that we want to see everything that relates directly or indirectly to the topic.
In my opening remarks, I said that I couldn't tell you whom we asked for what material until the release of the report. You'll see the list of witnesses and an indication of the sources that we consulted. However, until the report is released, the act unfortunately prohibits me from telling you to whom we sent a letter.
