Bush on July 24,2007:"“Those who justify withdrawing our troops from Iraq by denying the threat of Al Qaeda in Iraq and its ties to Osama bin Laden ignore the clear consequences of such a retreat.”"
Bush on March 13, 2002:" Deep in my heart I know the man is on the run, if he's alive at all. Who knows if he's hiding in some cave or not; we haven't heard from him in a long time.
... And he's just -- he's a person who's now been marginalized. His network, his host government has been destroyed.
...So I don't know where he is. You know, I just don't spend that much time on him, Kelly, to be honest with you."
