HNN Editor 2-20-16  The Sanders campaign has now confirmed that the protester in the video is Bernie Sanders.

A decades-old video has emerged showing Chicago cops arresting a young protester — who bears a striking resemblance to young Bernie Sanders — at a 1963 anti-segregation demonstration in Chicago.

The grainy footage could jump-start Sanders’ effort to attract African-American voters ahead of the Feb. 27 primary in South Carolina, where more than half of registered Democrats are black.

Backers of Democratic front-runner Hillary Clinton have questioned Sanders’ history with the civil rights movement.
