Yes, Clinton knew but he did not pass it on to Bush. He will claim he did, and has claimed such. But, quite characteristically, he lied. At the time of the transition, perhaps he thought he could just hide his incompetentence. Then, 9-11 happenened and changed things.
I've seen Clinton say that about bin Laden; oddly enough, it's not the story he told back during 9-11; but now he's tweaked it.
But I've yet to hear one person in this White House either confirm or deny it.
