"We've had every official in Hawaii, Democrat and Republican, every news outlet that has investigated this, confirm that, yes, in fact, I was born in Hawaii, August 4, 1961, in Kapiolani Hospital."

"We've posted the certification that is given by the state of Hawaii on the Internet for everybody to see. People have provided affidavits that they, in fact, have seen this birth certificate. And yet this thing just keeps on going."
