Hillary Clinton is expected to win the South Carolina primary on Saturday, and she's going to rely on the state's large African-American population to get her there. But after decades of building up relationships with the black community particularly in the south, her rival Bernie Sanders and his supporters are starting to question her record of working to help African-Americans.

VICE News traveled across South Carolina, talking to African-American voters about their relationship with the Clintons and to see whether Sanders' appeal, particularly among young people, is making any headway in these communities.
