One of them will be to contine funding the costs of the wars for the second half of fiscal year 2009, Congress had already appropriated $65.9 billion for the first half of fiscal year 2009. The Defense official confirms that the second half of the fiscal year 2009 request will be for $75.5 billion. That would bring the total war spending costs for fiscal year 2009 to $141.4 billion. In a letter to Congress on Dec. 31, Defense Secretary Robert Gates estimated that this request might be $69.7 billion. That estimate did not take into account the addition of troops into Afghanistan.
