Acknowledging that his presidential campaign has opened a racial debate, Sen. Barack Obama, who has a white mother and an African father, says if you look African-American, you are treated like one. Obama and his wife, Michelle, who also addresses the race issue, appear in an interview with Steve Kroft to be broadcast on 60 MINUTES, Sunday Feb. 11 (7:00-8:00 PM, ET/PT) on the CBS television Network. If, as expected, Obama declares his formal candidacy for the Democratic presidential nomination tomorrow, it will be his first interview to be broadcast after that event.
