Bush and Cheny continue to deny that Osama bin Laden was allowed to escape at the battle of Tora Bora.
Well, they would, wouldn't they?
As far as I know, no one of any seriousness who isn't a Republican shill denies that OBL escaped. For example, Peter Bergen recently wrote an excellent article entitled "The Long Hunt for Osama" for The Atlantic, in which he took up this issue, among many others that touch on OBL's current whereabouts.
An earlier post on this blog How Not to Finish the Job in Afghanistan and Iraq talked a bit about what happened at Tora Bora.
Update - August 7, 2005: I have more to say on the topic of Tora Bora in this recent post "Gary Berntsen on the Failure to get Osama bin Laden at Tora Bora".
