A US embassy staffer in Vienna writes AMERICAblog and says [President George W Bush defaced American flags]. Reportedly, a slew of conservative Republican Bush supporters wanted to get Bush's autograph on US flags. And Bush signed them. Right on the flags. Kind of ironic right before Senate Republicans force us to debate "flag burning," again, simply because they have no more ideas left.
