Archived video has been released which appears to show US presidential hopeful Bernie Sanders protesting against school segregation in Chicago in 1963.

The protest on Chicago’s south side took aim at racist education and housing policies - namely the proposed construction of a new school for black students made up of trailers.

These trailers known as “Willis Wagons” were used by the city to deal with overcrowding in black schools as a way to prevent integration.

As a student at the nearby University of Chicago, Mr Sanders served as a chapter president of the Congress for Racial Equality.

A clipping from the Chicago Tribune purports to show that during a protest, Mr Sanders was charged with resisting arrest and taken to jail.
