The youngest person to ever head the NAACP will endorse Bernie Sanders for president.

Former NAACP head Ben Jealous plans to make his announcement before next Tuesday’s New Hampshire primary, reps from Sanders’ campaign told CNN on Thursday.

His rival, Democratic front-runner Hillary Clinton, is relying on the support of minority voters in the upcoming Nevada and South Carolina primaries.

On Tuesday, Mr Sanders gained his fifth endorsement from a state lawmaker in South Carolina. Representative Joe Neal of Richland County said that he's impressed with Mr Sanders' platform to help restore the middle class.
