As we saw in various media reports, documents have demonstrated to the court that some information came from third parties. I would like to point out that those orders don't mean that people who provide that information are under investigation. That is an important distinction. They are third parties who have information that might be valid for the investigation and that has nothing to do with whether they are under investigation or not. Actually, it is the other way around.
