Found this comment on the Diplomas2.0 blog (here), that sums up this pathetic administration perfectly:
Couldn’t he have come out and said something along the lines of, “Given what is happening at the Naval Yard, we will postpone this event.”
“Team” Obama couldn’t take the chance President Obama would say,
“If I had a son he’d look like Aaron Alexis.”
