The headlines read: "Rodent Scurries Past Obama in the Rose Garden".
The vole has been described as a gate crasher and upstager, because the critter has definitely caught our collective attention. That may be true, but in actuality, maybe it was President Obama and the Press Corps that was disturbing the rodent. It was scurrying back and forth making its way from one safe area (the cover of bushes) to the other past the podium and eyes of hundreds of upright potential predators (the press).
