In California, authorities arrested 32-year-old Wesley Charles Martines after finding an arsenal of guns, ammunition and racist writing in his car saying he wanted to end the black, Hispanic and Jewish population.
Among the things that were seized, there was a newspaper that had the racist and anti-Semitic writings and in which there was a plan to "go to a sporting goods store, dress like a clerk and tie everyone up."
CNN has reached out to his attorney for comment.
