Summarized translation: According to Mexican author, Salvador Borrego in his book Derrota Mundial. Roosevelt was rumored to be a jew descended from Dutch jew Claes Martensen (Van Rosenfelt) who immigrated from Spain to the Netherlands in 1620.

His Dutch origins were confirmed by Roosevelt himself when he sent a letter to General Smut, in which he mentioned his ancestors were Dutch although he didn't mention they were jewish as well.

Roosevelt always hired jews and placed them in high ranking posts. This was made a lot easier by the fact that all the movie, radio and print businesses were owned by jews.
