Footage posted this week by a documentary production company called Kartemquin Films shows a 21-year-old Sanders being led away from a sit-in by police.
According to The New York Times, Sanders’ campaign confirmed that it was him in the video, as a student at the University of Chicago in 1963. Sanders was protesting segregation in Chicago Public Schools.
Meanwhile, The Chicago Tribune found a negative of a photo in its archives showing what appears to be the future presidential candidate getting arrested, as well. Sanders himself confirmed that it was him in the photo.
The photo is reportedly from the same event, where Sanders was charged with resisting arrest and found guilty. He paid a $25 fine.
