Judy Miller allowed Scooter Libby to attack Joe Wilson and then helped him to cover his tracks:

Mr. Fitzgerald asked about a notation I made on the first page of my notes about this July 8 meeting, “Former Hill staffer.” My recollection, I told him, was that Mr. Libby wanted to modify our prior understanding that I would attribute information from him to a “senior administration official.” When the subject turned to Mr. Wilson, Mr. Libby requested that he be identified only as a “former Hill staffer.” I agreed to the new ground rules because I knew that Mr. Libby had once worked on Capitol Hill.

Miller is a partisan operative, not a reporter.
