From Holden:

Halliburton cannot account for $1.8 billion of your money:

Halliburton Co. did not adequately account for more than $1.8 billion it billed the government for work in Iraq and Kuwait, a published report on the findings of Pentagon auditors said Wednesday.

The $1.8 billion amounts to 40 percent of the $4.18 billion KBR has already billed the Pentagon for its work feeding and housing military troops. The Pentagon could begin withholding payments from KBR if it determines it is owed money — though it has yet to do so.

Auditors’ concerns included more than $900 million in payments for dozens of dining facilities; auditors say that more than a third of those costs may be unjustified, the newspaper said. Auditors also are examining $180 million in costs charged for fuel from Kuwait that was delivered to Iraq.
