The Ferrer campaign criticized Green for the actions of supporters in the runoff that were construed as racist, involving literature with "New York Post" caricatures of Ferrer and Al Sharpton distributed in white enclaves of Brooklyn and Staten Island. Green said he had nothing to do with the dissemination of the literature. An investigation by the district attorney of Kings County, New York, Charles J. Hynes, came to the conclusion that "Mark Green had no knowledge of these events, and that when he learned of them, he repeatedly denounced the distribution of this literature and sought to find out who had engaged in it."
