Most likely, but it is interesting that the rumors or conspiracy theories or speculations implicate the OSS, forerunner of today's CIA. A CIA which seems, and historically has been, full of communist sympathizers and other anti-American intellectual types from (originally) the Ivy League.
I've seen the old news clippings implicating the OSS. IIRC it was leaker. I just ran across the article cleaning up some clipping from my father - WW2 vet.
