In a particularly dramatic scene in Weldons book, Countdown to Terror, the Pennsylvania Republican described personally handing to then-Deputy National Security Adviser Steve Hadley, just after Sept. 11, an Able Danger chart produced in 1999 identifying Atta. But Weldon told TIME hes no longer certain Attas name was on that original document. The congressman says he handed Hadley his only copy.
So he published this in a book without being certain? Without documented proof to back up the allegations?
