Barack Obama citizenship conspiracy theories

During Barack Obama's campaign for president in 2008, throughout his presidency and afterwards, there was extensive news coverage of Obama's religious preference, birthplace, and of the individuals questioning his religious belief and citizenship – efforts eventually known as the "birther movement", by which name it is widely referred to across media. The movement falsely asserted Obama was ineligible to be President of the United States because he was not a natural-born citizen of the United States as required by Article Two of the Constitution. Studies have found these birther conspiracy theories to be most firmly held by Republicans strong in both political knowledge and racial resentment.

Theories alleged that Obama's published birth certificate was a forgery – that his actual birthplace was not Hawaii but Kenya. Other theories alleged that Obama became a citizen of Indonesia in childhood, thereby losing his U.S. citizenship. Still others claimed that Obama was not a natural-born U.S. citizen because he was born a dual citizen (British and American). A number of political commentators have characterized these various claims as a racist reaction to Obama's status as the first African-American president of the United States.

These claims were promoted by fringe theorists (pejoratively referred to as "birthers"), including businessman and television personality Donald Trump, who would later succeed Obama as president. Some theorists sought court rulings to declare Obama ineligible to take office, or to grant access to various documents which they claimed would support such ineligibility; none of these efforts succeeded. Some political opponents, especially in the Republican Party, expressed skepticism about Obama's citizenship or were unwilling to acknowledge it; some proposed legislation that would require presidential candidates to provide proof of eligibility.

Theories have persisted despite Obama's pre-election release of his official Hawaiian birth certificate in 2008, confirmation by the Hawaii Department of Health based on the original documents, the April 2011 release of a certified copy of Obama's original Certificate of Live Birth (or long-form birth certificate), and contemporaneous birth announcements published in Hawaii newspapers. Polls conducted in 2010 (before the April 2011 release) suggested that at least 25% of adult Americans said that they doubted Obama's U.S. birth, and a May 2011 Gallup poll found that the percentage had fallen to 13% of American adults (23% of Republicans). The fall was attributed to Obama's release of the long form in April 2011.
