President Obama authorized the state of Hawaii to release a copy of his long-form birth certificate, resulting in massive media attention and a front-page splash by New York Times reporter Michael Shear on Thursday, “ Citing ‘Silliness,’ Obama Shows Birth Certificate .” But a Times media reporter wrongly suggested the “Birther” theories only erupted after Obama became president, among conservatives, when in fact they first circulated during the Democratic primaries, stirred up by supporters of Obama rival Hillary Clinton. Shear wrote: President Obama released his long-form birth certificate on Wednesday, a step that injected him directly into the simmering “birther” controversy in the hope of finally ending it, or even turning it to his advantage. The gamble produced dramatic television as Mr. Obama strode into the White House briefing room to address, head on, a subject that had been deemed irrelevant by everyone in his orbit for years even as it stoked conservative efforts to undermine his legitimacy as president.
