I have some suspicions, but I really think that it's the responsibility of this committee to find out by asking and seeking evidence.
Who authorized it? What was the intent behind it? Whom you call as witnesses could be critical, sir, to the finding of the fact and whatever conclusions you want to draw. I think the most important thing is to make sure it doesn't happen again, regardless of whether it was an honest mistake and there was no intent to mislead, as your contention was, or whatever words you chose to use.
