It is a looped (replayed) segment of THE WIDE LOAD FLOTUS making some smirking comment to her PANTLOAD spouse during the 9/11 ceremonies this past Sunday. The smirking expression on MOO's face coupled with a a few people attempting to decipher what she was saying leads to this explanation over on native You Tube:
Michelle Obama says something about the flag to BO and then smirks and shakes her head. What is it she is saying?..woe betide this woman if there is ever a confirmation or any audio on this event.
Some lip readers are saying she says - "all that for a flag?"
The ceremony beforehand included a choir singing and bagpipe playing before unfurling a tattered US flag.
UPDATE: I posted a new -- hopefully more clear -- video of the incident. A lot of the controversy rages over whether she said what she said or not -- of course. But a number of people have pointed out that the expressions, scowls, and shaking of her head from side to side was enough to evince disrespect for the ceremony and the solemnity of the occasion.
