Someone needs to ask that publishing house, where did they get the notion Obama was foreign-born in the first place? Obama certainly looks and sounds American. If he had walked into my office, I would have assumed he was American, unless told otherwise.
Why bother? They'll just lie. Truth is they thought he was born in Kenya because that's what Obama himself told them. Was he speaking in a Kenyan accent at the time? I wonder... But they'll never 'fess up to this. They'd rather blemish their reputation than tell the truth.
Sheriff Joe needs to pull his investigators out of Hawaii and have them start sniffing around Columbia and Harvard. Wouldn't be surprised if other literary agents made the same "typo".
