George Obama, 26, is the youngest of the presidential candidate's seven half-brothers and half-sisters, and while the other siblings are close, he told the magazine he was embarrassed he lived "on less than a dollar a month", and so never mentioned his famous half-brother.
"If anyone says something about my surname, I say we are not related. I am ashamed. I live like a recluse
George Obama said he had met his half-brother only twice, once at age 5 and then in 2006 when Senator Obama was touring Africa
in his autobiography, Senator Obama, 47, described his half-brother as a "beautiful boy with a rounded head".
George told Vanity Fair he had been homeless for 10 years
, and where he lived in Huruma was a "tough place".
"I have seen two of my friends killed," he said.
"I have scars from defending myself with my fists. I am good with my fists."
