A report by the Government Accountability Office says the U.S. has spent more than $300 billion on military operations in Iraq so far.
The report was released on the same day the White House rejected a war-funding deal from Congressional Democratic leaders, who said they offered to grant the president the authority to waive deadlines for withdrawal.
At stake is more than $90 billion the president says is needed to cover the costs of combat in Iraq and Afghanistan through September.
According to the report, the Defense Department's reported obligations to date include about $304.6 billion for operations in and around Iraq as part of Operation Iraqi Freedom, and an additional $74.2 billion for operations in Afghanistan, the Horn of Africa, the Philippines, and elsewhere as part of Operation Enduring Freedom.
$28.3 billion was also spent for operations in defense of the homeland.
