Just another Pol.
Bush, and apparently Cheney, have the ability to declassify information. Truman started it and the Supreme Court went along with it. Whether they can do that without memorializing it, i.e., let everyone else know they've declassified information, is open for debate.
One thing that isn't open to debate is that Bush's image as a straight talkin' Texan who deals only in facts is a complete hoax. Maybe now I'll stop hearing the drivel about "at least I know where Bush stands". Please. Bush declassified information (the NIE), fed dubious portions as "key findings" to sympathetic press members, then turned the finger of blame on the intelligence community and whined about bad information, all in the name of trying to smear a critic. Let's also not forget the critic happens to be correct on this issue.
Now the administration has the gall to claim they leaked the information in the public interest. There may be many things to admire about Bush personally; his ability to transcend politics and deal honestly with the public in a "take me or leave me" manner is not one of them.
It all depends on what the definition of "leak" is.
