From the Dallas Morning News:

HOUSTON – The former secretary for the Texas Air National Guard colonel who supposedly authored memos critical of President Bush’s Guard service said Tuesday that the documents are fake, but that they reflect real documents that once existed.

*boggle*

More:

Mrs. Knox said she did all of Lt. Col. Killian’s typing, including memos for a personal “cover his back” file he kept in a locked drawer of his desk.

She said she did not recall typing the memos reported by CBS News, though she said they accurately reflect the viewpoints of Lt. Col. Killian and documents that would have been in the personal file. Also, she could not say whether the CBS documents corresponded memo for memo with that file. . .

She also said the memos may have been constructed from memory by someone who had seen Lt. Col. Killian’s private file but were not transcriptions because the language and terminology did not match what he would have used.

For instance, she said, the use of the words “billets” and a reference to the “administrative officer” of Mr. Bush’s squadron reflect Army terminology rather than the Air National Guard. Some news reports attribute the CBS reports to a former Army National Guard officer who has a longstanding dispute with the Guard and has previously maintained that the president’s record was sanitized.

Mrs. Knox also cited stylistic differences in the form of the notes, such as the signature on the right side of the document, rather than the left, where she would have put it.

USA Today, which has done some very nice, solid reporting on this story, adds this nugget:

Another former Texas National Guard officer, Richard Via, also said that the documents were fakes but that their content reflected questions about Bush that were discussed at the time in the hangar at Ellington Air Force Base, where he had a desk next to Killian's.

Via said he and others he worked with "remember the physical, and him going to Alabama was an issue." He said Killian "made notes and put them in his files about things like that."

Killian kept the files because "he was trying to cover his ass," Via said. "He was always worried something would come back on him."

He said Killian's secretary "would type them up, and he'd put it in his desk drawer and lock it."

As I've said, it's long past time for CBS News to tell us how they obtained the documents, from whom they obtained them, and the process by which they investigated them and concluded that they were legit. It's what Murrow would've done.

But this is certainly an interesting wrinkle in the story: the concerns seem to have been legitimate, even if the memos are not.
