Speculation.
(I was wearing my tin-foil PJ's.)
What I was figuring was the Barnes got kicked out of office right as this was going on.
Wasn't in TX politics though at the time, so Ican't match Bush (senior) with Barnes or Bentsen or Bush (junior) or bentson (junior) ....
But they all knew each other, and somebody exposed Sharpstown and cost Barnes teh governor position.
1. If they reflect real documents that once existed, then who typed those if Killian didn't type and Knox typed everything for him? It would seem to be Knox.
2. Knox also doesn't like Pres. Bush for some reason. She sounds like the busybody secretary who considers herself lord of the castle by virtue of longevity since commanders and staffs come and go. Privy to moments of frustration and bad days on the part of commanders and touchy moments between commander and subordinate, she didn't know how to separate those moments from overall evaluations.
In short, if she had evaluated Patton after Eisenhower dressed him down, SHE never would have given him another command. Eisenhower, however, a great commander who knew when to be good cop and when to be bad cop, put his CONSIDERED opinion in his evaluations of Lt Bush. His considered opinion was that the Pres. was an excellent aviator.
I've rated guys in the army, too, and you don't look at the moments they tick you off. You look at the entire year, at what they produced, at what you've learned that explains them.
Knox apparently got confused between her role -- secretary -- and the command role. SHE was the secretary.
At least, however, she was honest about these memos.
3. That means her selection for who might have been a disgruntled person with "knowledge" should be looked at. SHE probably knows that she either told the person about or showed the person the originals once upon a time.
