Since his inauguration in 2008, the legitimacy of Barack Obama's birth has been very controversial. Many people believe that Obama is not a legitimate United States citizen which would make it constitutionally illegal for him to be President of the United States.

Some people claim that his birth certificate, which states he was born in Hawaii, is a fraud and that he was really born in Kenya. Others claim that during the time of his birth his father held British citizenship which made him a dual citizen, which is not a natural born citizen as contained in the United States Constitution.
