Marine One Departs White House

(CBS/Mark Knoller)

CBS News White House Correspondent Mark Knoller took this photo of Marine One carrying President Obama from the White House today, and we decided to post it purely because we thought it was cool. (Plus, it's a photo that cost significantly less than, say, $328,835.)

Mr. Obama took Marine One to Air Force One for a flight to Arizona, where he will deliver a commencement speech at Arizona State University this evening.
