NEW YORK (CNN)  -- Three Staten Island men are charged with violating voting rights, accused of assaulting African-Americans after Barack Obama's win in the November presidential election, authorities said Wednesday. A grand jury indicted Ralph Nicoletti, 18, Michael Contreras, 18, and Brian Carranza, 21, on charges of conspiracy to interfere with voting rights. All three pleaded not guilty in federal court Wednesday afternoon. According to the indictment, the three "knowingly and intentionally" conspired to intimidate African-Americans "in the free exercise and enjoyment of a right ... and because of having so exercised that right, to wit, the right to vote."
