BARACK Obama decided to ‘become black’ after being teased at university by students who called him ‘Oreo’, a new book claims.

In Barack Obama: The Story, Washington Post journalist David Maraniss reveals that at Occidental College in Los Angeles, Obama was mocked by UJIMA, the black student group on campus.

OBAMA… heckled at university, the future president listened to Bob Marley’s Survival

The future president got sick of being compared to the black and white biscuit he decided to define himself as more African than American.

He spent hours listening to the music of reggae king’s Bob Marley and became obsessed with his deeply political album Survival.

He also became a huge fan of Stevie Wonder and took a boring low-paid job so he could understand what it was like to be poor and black.
