By the way...his 'brother' is a half brother from one of his fathers 4 wives so why would he be obligated to help him?
My wife has half-siblings she has not lived with since she was six. They live in a poor country.
We have helped them. We are not even "rich" like Obama is.
They don't live in a "hut" (although her sister did when we found them after 17 years).
