The Supreme Court rejected an appeal that Barack Obama was not a natural-born citizen due to his dual British-American citizenship at the time of his birth. http://politicalticker.blogs.cnn.com/2008/12/08/scotus-rejects-appeal-questioning-obamas-citizenship/ . In sum, he was born on American soil, to an American mother, despite a father who was a British subject.
One claim is still finding its way through the courts, challenging Obama’s recorded birth in Honolulu, Hawaii.
I’m just glad to see this particular bit of idiocy die.
