The lawsuit by H. Brooke Paige, of the town of Washington, claims Obama is "not a natural born citizen" because both of his parents were not born in the United States.
Obama was born in Hawaii and he is a United States citizen.
Paige's argument is that Obama's father, Barack Hussein Obama Sr., was born in Kenya and so the president doesn't meet a 1758 definition of "a natural born citizen," according to reports.
Paige's lawsuit asks for an expedited hearing. The state's election ballots are scheduled to be printed in the next week.
