The Society of Professional Journalism’s code of ethics is apparently unknown to, and easily dismissed by, MSNBC’s Andrea Mitchell. On “Andrea Mitchell Reports” Monday, the anchor introduced Politico’s Jonathan Martin after playing a clip of former Godfather’s Pizza CEO Herman Cain suggesting some reporters at an event in Texas check the Society of Professional Journalism’s “code of ethics.” “Jonathan Martin is the senior reporter for Politico and broke the original story,” she said. “I assume you read the journalistic code of ethics, whatever that is.” Martin replied by saying he had his copy “well-thumbed.”
