Are you referring to this admission on his website that he was born a citizen of Kenya:
When Barack Obama Jr. was born on Aug. 4,1961, in Honolulu, Kenya was a British colony, still part of the United Kingdoms dwindling empire. As a Kenyan native, Barack Obama Sr. was a British subject whose citizenship status was governed by The British Nationality Act of 1948. That same act governed the status of Obama Sr.s children. Since Sen. Obama has neither renounced his U.S. citizenship nor sworn an oath of allegiance to Kenya, his Kenyan citizenship automatically expired on Aug. 4, 1982.

No, I'm referring to the apocryphal accounts of what was supposedly said during a Keyes/Obama debate in 2004. That's what roving's post (which I quoted and was responding to) was about.
