During Barack Obama's campaign for president in 2008 and in the years following his election, many conspiracy theories have been circulated, falsely asserting that he is not a natural-born citizen of the United States and consequently, under Article Two of the U.S. Constitution, that he is ineligible to be President of the United States.
