James von Brunn, who is accused of murdering security guard Stephen Johns in the course of a terrorist attack on the U.S. Holocaust Memorial Museum on June 10, had longstanding ties to far-right, racist groups. These connections are evident in his letters to retired Marine Corps General Pedro A. Del Valle, himself an activist of the far-right, who provided both material support and philosophical inspiration to von Brunn.
According to the memoir von Brunn published on his website (available here, in cached version), his connection to General Del Valle goes back at least to the mid-1960s. In fact, von Brunn credits Del Valle with inspiring his anti-Semitism by giving him a book.
"In 1964 Gen. Pedro del Valle gave me John O. Beaty's The Iron Curtain Over America. For the first time I learned how JEWS had destroyed Europe and were now destroying America."
