Bernie Sanders’ campaign responded Wednesday to Democratic National Committee chairwoman Debbie Wasserman Schultz after she said Sanders added “fuel to the fire” by not outright condemning violence at the Nevada Democratic convention over the weekend.

Appearing on CNN, campaign manager Jeff Weaver called out Wasserman Schultz for her treatment of the Sanders campaign, telling host Chris Cuomo that she’s been disrespectful of the campaign since its outset. He also said that while many at the DNC have been good to the campaign, Wasserman Schultz has been the “exception.”
