From "Media Matters":
"In the acknowledgements page of his forthcoming book, MSNBC analyst Pat Buchanan gives "special thanks to Marcus Epstein for the invaluable assistance and untold hours he devoted to researching ideas, issues, and anecdotes." Epstein, a writer and activist with a history of inflammatory statements about race and immigration, was previously arrested for attacking a woman with a "karate chop" and calling her the n-word.
In July of 2007, according to a factual proffer by the U.S. Attorney, Epstein "was walking down the street making offensive remarks when he encountered the complainant, Ms. [REDACTED], who is African-American. The defendant uttered, 'Nigger,' as he delivered a karate chop to Ms. [REDACTED]'s head. Ultimately, the defendant was stopped and arrested by Secret Service officers."
