Faulk says he and others in his section of the NSA facility at Fort Gordon routinely shared salacious or tantalizing phone calls that had been intercepted, alerting office mates to certain time codes of "cuts" that were available on each operator's computer.

"Hey, check this out," Faulk says he would be told, "there's good phone sex or there's some pillow talk, pull up this call, it's really funny, go check it out. It would be some colonel making pillow talk and we would say, 'Wow, this was crazy'," Faulk told ABC News.

Faulk said he joined in to listen, and talk about it during breaks in Back Hall's "smoke pit," but ended up feeling badly about his actions.

"I feel that it was something that the people should not have done. Including me," he said...

Asked for comment about the ABC News report and accounts of intimate and private phone calls of military officers being passed around, a US intelligence official said "all employees of the US government" should expect that their telephone conversations could be monitored as part of an effort to safeguard security and "information assurance."

"They certainly didn't consent to having interceptions of their telephone sex conversations being passed around like some type of fraternity game," said Jonathon Turley, a constitutional law professor at George Washington University who has testified before Congress on the country's warrantless surveillance program.
