From the Washington Post (hat tip to Josh Marshall at Talking Points Memo):
"A senior administration official, speaking on background because White House policy prohibits comment on an active investigation, said Bush sees a distinction between leaks and what he is alleged to have done. The official said Bush authorized the release of the classified information to assure the public of his rationale for war as it was coming under increasing scrutiny." (emphasis mine)
How typical of this Administration, and Bush in particular, to use a senior administration official speaking on background to a reporter to defend Bush's use of a senior administration official (Libby) speaking on background (as an annonymous former Hill staffer) leaking a classified document (the NIE) to a reporter (Judith Miller).
