In a fact sheet, the White House said that of the $87 billion, $66 billion would be for U.S. military operations in Iraq, Afghanistan and elsewhere.

Of that, $51 billion would be for supporting what the document called "a robust force in Iraq" of U.S. and multinational forces, and to repair and replace equipment. Currently there are about 140,000 U.S. troops in the country.

The money was to include an unspecified amount to allow U.S. troops in Iraq for a year to get two weeks of leave, $300 million for body armor and $140 million for "Humvee" vehicles.

An additional $20 billion was to help rebuild Iraq — $15 billion to set up an Iraqi army, a police force and other security, and $5 billion to rebuild drinking water and electrical systems, railroad lines and other facilities.

Overall, the paper said, initial estimates were that rebuilding the country would take $50 billion to $75 billion.

The administration is hoping the costs can be split about evenly between U.S. taxpayers, allied countries and funds from Iraqi oil sales, said one GOP congressional aide.

The request included an additional $11 billion for U.S. military efforts in Afghanistan, and $1.2 billion — including $400 million provided in earlier legislation — to help rebuild that country's infrastructure and security forces.
