"Hillary's Washington insiders rigged the system and Bernie never had a chance," the narrator in the new ad by the Defeat Crooked Hillary PAC says.

The narrator then notes how outgoing DNC Chairwoman Debbie Wasserman Schultz, who tendered her resignation effective after the party's convention, was tapped to be Clinton's honorary chair for her campaign's 50-state ground game effort surrounding her departure. 

"More corruption by Hillary and her cronies — now Hillary hires her DNC chair and wants you to just roll over? Hillary Clinton — she just doesn't get it."

It's aimed at inflaming the tensions within the party by keeping the latest controversy alive. 

Sanders supporters have expressed outrage at the release of the emails, pointing to the correspondence as proof that the party was working against their candidate and in favor of Clinton, now the Democratic presidential nominee. 

That frustration has boiled over at times during the Democratic Nation Convention, where Sanders supporters have shouted down speakers and staged walkouts despite the urging from Sanders and his top aides to stay united. 

A press release from the PAC adds that the group will use its analytics to target Sanders supporters at the convention in Philadelphia and in eight states. The ad is the first from the group, which re-branded itself from a pro-Ted CruzRafael (Ted) Edward CruzThe Hill's Morning Report — After contentious week, Trump heads for Japan Senate GOP votes to permanently ban earmarks Jim Carrey fires back at 'Joe McCarthy wanna-be' Cruz MORE super-PAC during the Republican presidential primary.
