I heard this more or less "live" on NPR's "Marketplace" where the comment was originally aired. I was not really paying attention to who was talking and I thought it was some dopey low-level redneck volunteer at the Astrodome.
When I realized the next day it was Barbara Bush I nearly fell out of my chair!
I immediatly went to the wikipedia and helped flesh out the bit under "controversies" which you can find HERE.
One can only imagine what this family says when the camera is not around!
PS - someone said this has not been picked up by mainstream media - it has - prominent features in NY Times, CNN, etc. etc. I think in a way it is too funny to be really shocking.
