President Obama's half-brother George Obama stars in an anti-Obama documentary by Dinesh D'Souza. Obama met his brother once when he visited Kenya and wrote about it in his memoir "Dreams From My Father".
One has to wonder if this is yet another phony bit from Obama as has been revealed in David Maraniss's book "Barack Obama: The Story" in which many details of Obama's life were debunked.
From "Dreams From My Father":
'I took comfort in the fact that perhaps one day, when he was older, George, too, might want to know who his father had been, and who his brothers and sisters were, and that if he ever came to me I would be there for him, to tell him the story I knew.'
