The half brother of President Barack Obama Mark Ndesandjo has a new book “Nairobi to Shenzhen”. Mark Ndesandjo says Barack Obama Sr beat his mother Ruth Nidesand and Mark.

Mark Ndesandjo has not talked to media until this week as his book gets released, one of several from Obama relatives. Mark lives in Shenzhen, near Hong Kong. The book is self published.

Mark Ndesandjo explains that Barack Obama Sr met Nidesand as a graduate student at Harvard University. The couple returned to Obama Sr’s home in Kenya. Mark Ndesandjo was born along with a brother David who later died in a motorcycle accident, reports AP.

There in Kenya Obama Sr had children with his first wife even while with Ruth. President Obama would be born in Hawaii in 1961 and in 1963 his mother Stanley Ann Dunham and Obama Sr separated. The AP reports says “at least” six other children by Obama Sr were born in Kenya before his passing in 1982 in a car crash.
