Katie Couric's Notebook: Power Lunch

It was the ultimate power lunch.

President-elect Obama sat down at the White House today with all four members of what may be the world's most elite club - President Bush and former President's Bush, Clinton and Carter.

Who wouldn't want to be a fly on the wall for that conversation?

This was the first White House gathering of all living Presidents since 1981. The lunch was Mr. Obama's idea and President Bush was happy to set it up.

On the menu: some good advice, a little inside information, and maybe a few war stories. The president-elect said he hoped to learn from the successes of his predecessors. After all, they tackled some of the same issues now on his plate: economic crises and the never-ending efforts to bring peace to the Middle East.

Mr. Obama gets a lot of advice.

But this was a chance to hear directly from the only men who truly understand the awesome responsibility he is about to face.
