The Democratic National Committee's (DNC) new slate of at-large delegates threatens to push out longtime members, many of whom have ties to the more progressive wing of the party.
The moves have frustrated the progressive-leaning Democrats who feel the staff shakeup is retribution for their opposition to its new Chairman Tom Perez during February's chairman race.
NBC News first reported the grumblings over Perez's slate of at-large members on Wednesday night.
Ousted and demoted DNC veterans reportedly include Ray Buckley, James Zogby, Alice Germond and Barbra Casbar Siperstein, the network reported, adding that a common thread linking many of them is their support of Sen. Bernie Sanders (I-Vt.) and Rep. Keith Ellison (D-Minn.), who ran against Perez for the chairmanship.
