Soledad O'Brien's 'Black In America' Airs December 9 (VIDEO)

Soledad O'Brien is out with her latest installment in CNN's "Black In America" series.

The special, called “Who Is Black in America?” explores racial identity in black communities. It is the fifth part of the "Black In America" series, which debuted in 2008 with an exploration of black women's experiences with family and education. The latest documentary airs Sunday, December 9 at 8 p.m. EST.

O'Brien, who is multiracial and identifies as "black," spoke out about her own racial identity and why it matters to viewers watching "Black In America."

"You know, white people really have a luxury in that they get a range of stories, that they’re not defined by five stories," she explained. "So I think that the difference with 'Black in America' was the filter did matter. That there are only going to be five stories and we want to know exactly who you are and what your credentials are to be telling our story."

She said that she "used to take great offense" at questions about her ethnic background, but no longer does. "I think I was part of "Black in America" even in the context of who is the filter of the story and so it became relevant, so I really stopped hating answering that question because I felt like my job is to elaborate and explain for people who I am," she said.
