From the article:

I do not know—but I believe that Richard Feynman is either a Communist or very strongly pro-Communist—and as such as a very definite security risk. This man is, in my opinion, an extremely complex and dangerous person, a very dangerous person to have in a position of public trust… In matters of intrigue Richard Feynman is, I believe immensely clever—indeed a genius—and he is, I further believe, completely ruthless, unhampered by morals, ethics, or religion—and will stop at absolutely nothing to achieve his ends.

The article speculates who might have written this, having read a lot of books both by and about Feynman I don't know if I agree or not.
