It's a two-part answer, sir.
In conducting his inquiry, I believe Mr. Justice O'Connor had unfettered and full access to any and all information that related to this.
Secondly, as you know, there are some aspects of this matter that are subject to national security confidences. They have not been made explicit in the public report, and they are in fact now the subject of review by the courts. Whether or not there was anything related to Mr. Arar emanating from American authorities in that regard, I don't know.
