Other questions abound: How could a program with the sterling reputation of "60 Minutes," which created the television newsmagazine during the Johnson administration, have stumbled so badly? And how could Rather, at 72 the dean of the network anchors, have risked his reputation on such a story in the heat of a presidential campaign?

One mystery among CBS staff members is why network officials remained so confident for so long about the documents as so many questions arose.

1. "The Kerry campaign had absolutely nothing to do with these documents, no ifs, ands or buts," spokesman David Wade said.

2. [Suspected document source] Bill Burkett[] said in an Aug. 21 e-mail to a list of Texas Democrats that after getting through "seven layers of bureaucratic kids" in the Democrat's campaign, he talked with former Georgia Sen. Max Cleland about information that would counter criticism of Kerry's Vietnam War service. The Associated Press obtained a copy of the e-mail Saturday. "I asked if they wanted to counterattack or ride this to ground and outlast it, not spending any money. (Cleland) said counterattack. So I gave them the information to do it with," Burkett wrote.
