was Dov Zakheim. Here's some paragraphs from Wikipedia. There is much more.
Point being - has anyone asked him? His bio said he reduced the amount somewhat Hmmmmm.
The company he led prior to becoming Comptroller was said to have manufactured remote control for aircraft.
He worked politically to put George in office.
"From 1987-2001, Zakheim was CEO of SPC International, a subsidiary of System Planning Corporation, a high-technology analytical firm. During that period he served as a consultant to the Office of the Secretary of Defense, and sat on a number of major DoD panels, including its Task Force on Defense Reform (1997) and the DoD's first Board of Visitors of Overseas Regional Centers (1998-2001).
Zakheim is also a member of the Council on Foreign Relations, the International Institute for Strategic Studies, and the United States Naval Institute, and a member of the editorial board of the journal The National Interest. He is a three-time recipient of the Department of Defense's highest civilian award, the Distinguished Public Service Medal, as well as other awards for government and community service.
He was an Adjunct Scholar of the Heritage Foundation, a Senior Associate at the Center for Strategic and International Studies, and published over 200 articles and monographs on defense issues.
He was then appointed to be Undersecretary of Defense and Comptroller from 2001 to 2004 under the George W. Bush administration, and served in this capacity until April 2004. During his term as Comptroller, he was tasked to help track down the Pentagon's 2.6 trillion dollars ($2,600,000,000,000) worth of unaccounted transactions <1>. He initiated a number of processes that led to the reduction of that sum by two-thirds by the time of his departure, and to its reduction by over 99.9% within two years thereafter"
http://en.wikipedia.org/wiki/Dov_S._ZakheimAnyone going to ask him where he THINKS the money is?
Think about how many people have never talked about the missing money in the DOD or have never heard about it.
I think he, Rumsfeld, and Zakheim's successor should sit down for an interview.
