From NBC News:
Immediately after Perez’s selection as party chairman in late February, an adviser to outgoing DNC Interim Chair Donna Brazile, Leah Daughtry, asked every employee to submit a letter of resignation dated April 15, according to multiple sources familiar with the party’s internal workings.
A committee advising Perez on his transition is now interviewing staff and others as part of a top-to-bottom review process to decide not only who will stay and who will go, but how the party should be structured in the future.
…The DNC will embark on a national search to fill key party positions, overseen by the 30-odd members of the transition advisory committee.
What is unclear with the house-cleaning move is what “roles that new deputy chair Keith Ellison — the Minnesota congressman who narrowly lost the party’s chair race to Perez — and other vice chairs will play,” reports CNN.
