This is the first time I've heard anyone claim that Libby told Miller that there was a CIA vendetta against the administration. I wonder how Kincaid knows that; is he just guessing, or did Libby or Miller tell him? And if it's true, why has Miller never talked or written about it?
She's saving it for her book.
Miller did write about it
As I told the grand jury, I recalled Mr. Libby's frustration and anger about what he called "selective leaking" by the C.I.A. and other agencies to distance themselves from what he recalled as their unequivocal prewar intelligence assessments. The selective leaks trying to shift blame to the White House, he told me, were part of a "perverted war" over the war in Iraq.
