WASHINGTON (AP)- A genealogical researcher says presidential hopeful Barack Obama had white ancestors who owned slaves.
William Reitwiesner, in what he calls a first draft into Obama's roots, says he found the information in 1850 Census records from Kentucky. Obama's father was from Kenya and his mother was a white woman from Kansas.
Reitwiesner says one of Obama's great-great-great-great grandfathers owned a 15-year-old girl and a 25-year-old man.
Reitwiesner says the same records show one of Obama's great-great-great-great-great grandmothers owned a 60-year-old man and a 58-year-old woman.
An Obama spokesman notes that while a relative owned slaves, "another fought for the Union in the Civil War."
Reitwiesner says he also found that two other presidential candidates, Republican John McCain and Democrat John Edwards, were descendants of slave owners.
