The right-wing professional liars that parroted this crap are not in the habit of following up if their sources make corrections. That's the beauty of the right-wing slime machine. While the initial source of the lie may be held to account and forced to make a correction, the liars on radio and Fox News' "opinion hours" who forwarded the lie can let it fester with complete impunity. This is a crucial part of Rupert Murdoch's war on journalism: little to no enforcement of journalistic principles.
