She admits it was an error on her part. Just coincidentally she said he was born in Kenya. Why not Tanzania?
Sorry, while I have no doubt he was born in Kenya, it is his mothers status which matters, not his. But more importantly, why the lies?
You never heard of resume inflation? You think people writing autobiographies don't shade events in their favor? You think agents don't exaggerate the bios of their clients? As to why Kenya - his father was from Kenya, and book was about his feelings about his father. It was a logical tie-in, as opposed to Zimbabwe, Tanzania or Liberia, which had no relationship to the narrative, unless you think all African country names sound alike.
