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. 
NBC News' Tim Russert shows Clinton a headline from The State newspaper that calls her attacks "painful for black voters" and reads Clinton an op-ed from The Washington Post that argues she is "minimizing" Martin Luther King Jr.'s message of "I have a Dream."

It ends with a message to voters:"The Clintons: only with you when they need you." 
Clinton's primary bid has been boosted in large part thanks to overwhelming support from black voters--she won three-quarters of the black vote in Nevada, according to exit polls. 
Her campaign stresses issues that disproportionately affect minority voters, including criminal justice, voting rights and gun violence. 
And she's also leveraged her support from prominent black lawmakers and activists who have accused Sanders, who hails from lily-white Vermont, of coming late to the party on racial justice.
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.
