My recollection is that all along the administration claimed that career bureaucrats at defense were in charge of contracting and Cheney had nothing to do with the process. So why would there have been any coordination with the Vice President's office. I don't know DC well enough, but my understanding is there is no official oversight role for the VP. So the defense that this was all standard operating procedure sounds like a big fat lie.
