Is he kidding?
From the AP:

'The New York Times disclosed last month that the NSA had been conducting the domestic surveillance since 2002. The Justice Department on Friday opened an investigation into who told reporters about the program.

"The fact that somebody leaked this program causes great harm to the United States," Bush said.'

He's kidding right? No wait, I'm sorry, he's lying. I guess there is a difference. Lying every time you open your mouth causes great harm to the United States. Only this guy would infer that revealing a possibly illegal act on his part is treasonous. As Bill Hicks would say, "Jesus, what balls."
