Revilo Oliver (Revilo is Oliver spelled backwards) made his comment about JFK in his article "Marxmanship in Dallas" published in American Opinion magazine, the JBS house organ, in February, 1964. But Oliver left the JBS in the summer of 1966--I heard that it was due to some Judeophobic remarks he had made at a rally. However, he claims in an article available on a website devoted to him that he resigned from the JBS because he discovered that it was controlled by a "committee of Jews."
I have heard Revilo P. Oliver called “the Grand Palindrome.”
