The Bush administration on Monday formally asked Congress for an additional $45.9 billion in fiscal 2008 emergency spending for military and diplomatic operations in Iraq and Afghanistan, according to congressional aides.

The new request brings to $196.4 billion the total requested for the war in the fiscal year that began Oct. 1. That includes $189.3 billion for the Defense Department and $7.1 billion for the State Department and other agencies. As emergency spending, the money does not count against the year’s budget caps for other types of discretionary spending.

In February, as part of his fiscal 2008 budget submission, President Bush requested $145.2 billion in war funding, including $141.7 billion for the Pentagon.

In July the president requested an additional $5.3 billion for mine-resistant vehicles to protect soldiers from roadside bombs. Congress provided those funds in the fiscal 2008 stopgap funding resolution, enacted last month, which will keep the government funded through Nov. 16.

Congress is not expected to pass a new war funding measure this calender year, although it will have to provide some additional money. Earlier this month, House Appropriations Committee Chairman David R. Obey, D-Wis., said he will not move a war funding bill out of his committee in 2007, saying the president must change his policy in Iraq before Obey will advance the bill.

Congress could allow the Pentagon to borrow war funds from its regular fiscal 2008 spending bill, once that measure is enacted, or it could attack a few months’ war funding to some other appropriations measure in the weeks between now and adjournment.
