<B>Obama's father was an abusive alcoholic, his half-brother says</B> By Dugald McConnell and Brian Todd, CNN December 20, 2013 -- Updated 0556 GMT (CNN) -- Barack Obama's father was more abusive and violent than the president was aware of, according to his half-brother, who has written a memoir about their father. But he was also an alcoholic, a "social failure" and an abusive husband, he said. "I remember the sounds of my mothers' screams and I remember the sounds of breaking, things breaking," he told CNN. "And I remember that I couldn't protect her. That's something that no child ever forgets." He said he especially remembered a violent episode when he was 6 or 7. "My father actually broke -- came in the door, against the restraining order, and held a knife to my mother's throat," he said. Unlike Obama, Ndesandjo grew up with their father. http://edition.cnn.com/2013/12/20/politics/obama-father-abusive/index.html?hpt=hp_t3 Dreams from my father, indeed.
