WASHINGTON - Confronting a grim economy and a Middle East on fire, Barack Obama turned Wednesday to perhaps the only people on the planet who understand what he's in for: the four living members of the U.S. presidents' club. In an image bound to go down in history, every living U.S. president came together at the White House on Wednesday to hash over the world's challenges with the president-elect. There they stood, shoulder-to-shoulder in the Oval Office: George H.W. Bush, Obama, George W. Bush, Bill Clinton and Jimmy Carter.

"This is an extraordinary gathering," Obama said, looking plenty at ease in the humbling office that will soon be his.

"All the gentlemen here understand both the pressures and possibilities of this office," Obama said. "And for me to have the opportunity to get advice, good counsel and fellowship with these individuals is extraordinary. And I'm very grateful to all of them."

Bush, blistered without mercy by Obama during the campaign season, played the role of gracious host.
