The economic costs of the wars in Iraq and are estimated to total $1.6 trillion _ roughly double the amount the has requested thus far, according to a new report by Democrats on Congress' Joint Economic Committee.

The report, released Tuesday, attempted to put a price tag on the two conflicts, including "hidden" costs such as interest payments on the money borrowed to pay for the wars, lost investment, the expense of long-term health care for injured veterans and the cost of oil market disruptions.

The $1.6 trillion figure, for the period from 2002 to 2008, translates into a cost of $20,900 for a family of four, the report said. The Bush administration has requested $804 billion for the Iraq and Afghanistan wars combined, the report stated.

For the Iraq war only, total economic costs were estimated at $1.3 trillion for the period from 2002 to 2008. That would cost a family of four $16,500, the report said.

Future economic costs would be even greater. The report estimated that both wars would cost $3.5 trillion between 2003 and 2017. Under that scenario, it would cost a family of four $46,400, the report said.

The report, from the committee's Democratic majority, was not vetted with Republican members. Democratic leaders in Congress, including Senate Majority Leader Harry Reid, D-Nev., seized on the report to criticize Bush's war strategy. The White House countered that the report was politically motivated.

"This report was put out by Democrats on Capitol Hill. This committee is known for being partisan and political. They did not consult or cooperate with the Republicans on the committee. And so I think it is an attempt to muddy the waters on what has been some positive developments being reported out of Iraq," said White House press secretary Dana Perino. "I haven't seen the report, but it's obvious the motivations behind it."

The report comes as the House and Senate planned to vote this week on another effort by Democrats to set a deadline for withdrawing troops from Iraq as a condition for providing another $50 billion for the war.

Reid said the report "is another reminder of how President Bush's stubborn refusal to change course in and congressional Republicans' willingness to rubber stamp his failed strategy _ has real consequences at home for all Americans."
