President Bush is putting the finishing touches on his request for $56 billion to finance the Persian Gulf war.

The president could ask Congress as early as Tuesday for the additional money for the fight with Iraq, now in its second month.White House officials, speaking on condition of anonymity, have said Bush will propose paying for the war with $41 billion in foreign contributions and $15 billion in U.S. taxpayers' dollars.

The president will say that amount will be enough to pay for the fighting through March, the officials said. A request for still more money is expected when the war's costs, now largely unpredictable, become clearer.

The measure will cover the extra salary costs the war has generated for troops and the replenishment of used weapons. Congressional backing of the request is not in doubt.
