The new video is called "The Clintons Hope You Forgot," and cobbles together footage of newscasters highlighting some of the more controversial moments and headlines surrounding that 2008 race.

But Sanders has fought that characterization, noting his early involvement with racial justice protests and his arrest back in the 1960s for protesting unfair housing practices.
