Civil Rights leader and legendary athlete, Dr. John Carlos, made history on the Olympic podium in 1968. After medaling in the 200 meter race in Mexico City, he and Tommie Smith raised their fists in the Black Power salute during the national anthem. Marking fifty years since that iconic moment, Dr. Carlos spoke with Sports Editor of The Nation and co-author of his memoir, Dave Zirin. Dr. Carlos shares his story of meeting Dr. Martin Luther King Jr., the hardships he faced after the '68 Olympics, and the message he has for athletes continuing the movement for racial justice today.
