Obama also has another half brother who lives on $12 a month in a hut in Kenya. But you never read anything about him helping the man.
As for this Jewish half brother, remember that Barack Hussein Senior was very good at dropping his pants and getting down to business whenever he felt the urge. (Typical Third World behavior.) Anyway, after leaving Stanley Anne Dunham, Barack Senior took up with a Jewish woman named Ruth Beatrice Baker who came with him back to Kenya.
Personally I don't understand what these women saw in that man.
