On his last day in office (Jan. 20, 2001), President Clinton departs a farewell rally at Andrews Air Force Base and heads for the plane. Photographer Diana Walker -- also in her last day on the White House beat -- says of this moment, "I can't imagine his feelings that day -- perhaps his face tells us a little."

"After a farewell at Andrews Air Force Base, former President Clinton heads for the plane. I can't imagine his feelings that day -- perhaps his face tells us a little. This was my last day on the White House beat. I'd been where I wanted to be, watching the last moments of the President being the President and welcoming a new President. I had very mixed feelings. I'd been to wonderful places, been witness to exciting events and some truly remarkable moments. I'd seen our political system at very close range and had some images to show for it. I had been very lucky and not felt it was time for me to go. As I watched the President and First Lady drive off toward their new life, I had mine too. Suddenly I remembered that January 20 was my birthday, and once again I'd spent it with a President." -- Diana Walker
