Some prominent members of the the Democratic National Committee's (DNC) are frustrated with the party's new slate of at-large delegates.

Those DNC members include Ray Buckley, James Zogby, Alice Germond and Barbra Casbar Siperstein, who supported Ellison, who ran against Perez for the chairmanship, or Sanders.

Buckley, who ran against Perez for the top DNC role before endorsing Ellison, was pushed out of his positions on the DNC's Executive Committee and Rules Committee, NBC News reported. "I understand the chair can do as he pleases, but still, it's all just very disappointing," Buckley told the news outlet. "It is quite unusual for a former party officer who has been serving on the DNC for forever to just be left out in the cold without even a call from the chairman," said Germond, who had served on the DNC since the 1980s. "So I assumed it had something to do with myself support for Keith." Zogby tweeted his disappointment on Thursday , arguing that "this doesn't bring the party together. It deepens the divide at a time we need all hands on deck for '18 & '20."
