Let's all give the liar as much rope as he needs to hang himself.
Someone should ask which Federal Agency provided the money?
Someone should ask which budget line item or which recent court decision allows for a $400 million expenditure by the Executive Branch.
Someone should ask the federal Department or Agency Inspector General of every agency involved who in that Agency has a $400 million dollar signature authority to expend funds.
Someone should ask to see the receipts from the people who have $400 million payment authority for the money to be transferred to whatever agency/contractor had the unmarked aircraft.
Then people who did not have authority to distribute funds not in the budget or not a Budget line item should be charged with criminal offenses. Then flip them up the chain of command to the Big Zero or whoever will take the fall for him. The people who do not question illegal orders should pay the price for their actions.
