WASHINGTON (CNN) - President Bush will meet Federal Reserve Chairman Alan Greenspan Monday before a briefing of key members of Congress on an emergency war budget request officials say will total about $75 billion.

White House spokeswoman Claire Buchan also said that Greenspan was at the White House earlier Monday to meet with members of Bush's economic team but that the president was not present.

She gave few details about the afternoon meeting, other than to say "they'll be talking about the current state of the economy."

Besides Greenspan and Bush, Treasury Secretary John Snow and Stephen Friedman, director of Bush's National Economic Council, were to take part in the afternoon meeting before the White House economic council meets, Buchan said.

The president plans to formally unveil the spending request Tuesday at the Pentagon, and then will travel to Central Command headquarters in Tampa, Fla., Wednesday to meet with military personnel involved in managing the Iraqi war effort.

It also comes at the beginning of a week in which senior aides say Bush will make a number of public appearances, including his announced stops at the Pentagon and Central Command headquarters. The latter is most likely to include a visit to a U.S. military base involved in the Iraq war effort.

The senior official said the emergency budget request -- formally known as a supplemental budget request for this fiscal 2003 budget year -- will be sent to Congress later this week and Bush will discuss the numbers with key members of Congress, including the chairmen and ranking members of the House and Senate appropriations committees.

Bush said Sunday he was satisfied with the war effort so far, while voicing his condolences for those killed and his concern for those wounded and taken prisoner.

Senior aides repeatedly have said a major White House concern is that the public appears to believe it will be a quick conflict with a minimum of U.S. casualties, and say from Bush on down the administration will continue to press the case that the war could be longer and more dangerous than many might have believed.
