President Barack Obama poses with the "Racing Presidents" beneath Washington Nationals Park on June 11, 2015.
Photographer Pete Souza describes the scene: "We had just stopped by the annual Congressional Baseball Game at Nationals Park and we were already driving away underneath the stadium. The President asked the Secret Service to stop the motorcade when he spotted The Racing Presidents (they compete against each other in a running race during every game). My vehicle was 100 feet ahead so I jumped out and ran back in time to catch them in a group photo for posterity."
