SEATTLE (Reuters) - A prominent leader of the African-American community inSpokane,Washington, is under investigation for identifying herself as black on a city job application, as a white couple set off a media storm by saying they are her biological parents.Rachel Dolezal, 37, serves as chair ofSpokane's independent police ombudsman commission, and identified herself as white, African-American and Native American when applying for the job,City CouncilPresidentBen Stuckartsaid in an interview on Friday.Dolezal is also president of theSpokanechapter of theNational Association for the Advancement of Colored People(NAACP), the nation's oldest and largest civil rights organization.The city probe was opened after local media questioned Dolezal's racial identity, Stuckart said. The questions came after Dolezal filed police complaints of racial discrimination, most recently that she received hate mail."We are gathering facts, looking at city code, to determine if any city policies in relation to boards or commissions were violated," Stuckart said.Spokane'sSpokesman-Reviewnewspaper reported that Dolezal's birth certificate shows her born to a whiteMontanacouple, who say they are of European and Native American descent.Dolezal did not immediately respond to Reuters' requests for comment.
