Is this video of Bernie Sanders being arrested?

A video has emerged that appears to show Democratic presidential candidate Bernie Sanders being arrested in Chicago in 1963.

The video, posted to Vimeo by Kartemquin Films, was shot on Aug. 5, 1963 by filmmaker Jerry Temaner, who was recording a protest on the city’s South Side. Activists were protesting the city’s plan to build a new school out of a group of aluminum mobile homes referred to as “Willis Wagons.” Opponents considered these wagons as methods of containing black students.

In the video, a young man — who looks similar to other photos of Sanders around that time — is shown in handcuffs, being escorted away by police. At the time, Sanders was a student at the nearby University of Chicago, where he was president of the university’s chapter of the Congress for Racial Equality.

Sanders was charged with resisting arrest and taken to jail that day.

The video’s emergence comes at a time when Sanders’ Civil Rights activism history has been called into question by Hillary Clinton’s supporters, most notably Rep. John Lewis (D-Ga.).

Sanders has made a concerted effort to reach black voters, who have backed the Clintons in the past. Erica Garner, whose father died in 2014 while in a police chokehold in New York, has come forward to endorse Sanders and has campaigned for him in South Carolina.

He also recently met with the Rev. Al Sharpton at a high profile meeting at a popular soul food restaurant in Harlem.
