 Various criticisms were made during the campaign concerning Obama's religious background and heritage, both by political opponents and by some members of the media.In 2004, conservative columnist Andy Martin issued a press release alleging that Obama had "sought to misrepresent his heritage," indirectly triggering one of the first viral emails spreading false rumors about Obama's background.The issue lay fallow for almost three years, but picked up again in late 2006, as the announcement of Obama's presidential candidacy approached.
