It seems that Obama has more relatives in need than his shanty-living  half-brother in Kenya. From the UK Times:

Barack Obama has lived one version of the American Dream that has taken him to the steps of the White House. But a few miles from where the Democratic presidential candidate studied at Harvard, his Kenyan aunt and uncle, immigrants living in modest circumstances in Boston, have a contrasting American story.

Zeituni Onyango, the aunt so affectionately described in Mr Obama's best-selling memoir Dreams from My Father, lives in a disabled-access flat on a rundown public housing estate in South Boston.

A second relative believed to be the long-lost "Uncle Omar" described in the book was beaten by armed robbers with a "sawed-off rifle" while working in a corner shop in the Dorchester area of the city. He was later evicted from his one-bedroom flat for failing to pay $2,324.20 (£1,488) arrears, according to the Boston Housing Court.
