Potter

Incorrect.
(hint: he’s more commonly known by his first initial & middle name)
C. Everett Koop
Poet Edward Estin
Don’t you mean “edward estin”?
And under whose administration did he serve?
Looks like he served in the U.S. Army during the Wilson Administration, but not in an official capacity as a poet: E. E. Cummings - Wikipedia
U.S. Army Chief of Staff George C.
Sorry, I’d overlooked:
Angleton.
Play on from “U.S. Army Chief of Staff George C.,” please.
Marshall, Jr.
OSS/CIA officer and Presidential grandson Kermit
Roosevelt
Former ex-Senator and holds a unique distinction: William
Proxmire
(blasted by Arthur C. Clarke in a short story for opposing NASA funding)
Secretary of War Henry
Dearborn
Secretary of War Henry L.
Stimson
Nope!
It is Edward W. Proxmire so the name doesn’t work.
Also the “ex” Senator is a key part of the clue
The “unique” distinction is one that cannot be matched
There is no middle initial since he did not have a middle name
Still in play
Former ex-Senator and holds a unique distinction: William
Clearly you’re thinking of someone else, and that’s fine, but I beg to differ: William Proxmire - Wikipedia
I can think of no other U.S. senator about whom a famous sf author wrote. He is unique.
