WASHINGTON (AP) -- President Bush has sent lawmakers a $70 billion request to fund U.S. operations in Iraq and Afghanistan into next spring.

Friday's request fills in the details of the $70 billion placeholder that the White House asked for when it sent its budget to Congress in February.

Congressional analysts say Bush's request would bring the total spending to fight terrorism and conduct the wars in Iraq and Afghanistan to $875 billion.

The bulk of the money, $45 billion, would fund combat operations, but there's also $3 billion to deal with roadside bombs and $2 billion to cope with rising fuel costs.
