Rev. Al Sharpton has spent his life speaking up, loudly, against racism and racial violence. The new documentary "Loudmouth" chronicles his path from a teenage preacher to a racial justice firebrand on the streets of 1980s New York City. Rev. Sharpton joins MetroFocus to talk about his fascinating journey – from his days marching through then-hostile white neighborhoods like Bensonhurst and Howard Beach - exposing a racist side of New York many didn’t want to believe existed - to his current place as media elder statesman and presidential adviser.
