Conspiracy theories about the citizenship of Barack Obama are ideas that reject the legitimacy of the United States citizenship of President Barack Obama or his eligibility to be President of the United States. Some of these conspiracy theories allege that Obama was born in Kenya, not Hawaii, and that his birth certificate is a forgery. Others allege that Obama is a citizen of Indonesia, or that because he had dual citizenship at birth (British and American), he is not a natural born citizen of the United States, which is a requirement to be President of the United States under Article Two of the United States Constitution. These conspiracy theories received attention in mid-2008 following Obama's victory in the Democratic primaries, in late 2008–early 2009 with regard to the Electoral College vote and Obama's inauguration, and again in mid-2009 following a lawsuit by Army reservist Stefan Cook.
