Yes, this point is illustrated in his comments from this article:
McCain replied: I think that the Obama campaign should and will give all information necessary. You know, in all due respect to the Republican National Committee and anybody right now, I think we should try to be working constructively together, not only on an issue such as this, but on the economy stimulus package, reforms that are necessary. And so, I don’t know all the details of the relationship between President-elect Obama’s campaign or his people and the governor of Illinois, but I have some confidence that all the information will come out. It always does, it seems to me.
What a jerk!!!
