John Eaves resigned as Fulton County chairman on Aug. 23, an expected move that is required for him to officially join the Atlanta mayoral race.

Commissioner Bob Ellis, whose District 2 includes part of northern Sandy Springs, has been serving as vice chairman and now will be interim chairman pending a special election, according to a Fulton County spokesperson.

The special election for the chairman seat has yet to be scheduled, though it is expected to be held Nov. 7 to match local municipal elections. The race has two announced candidates: Robb Pitts, a Democratic former Fulton commissioner and Atlanta City Council president, and Gabriel Sterling, a Republican Sandy Springs City Council member.

With Eaves’ resignation, the seven-member Fulton Board of Commissioners is now operating with two vacant seats. Vice Chair Joan Garner died in April, and another special election will be scheduled to fill her Atlanta-area District 4 seat.

The Atlanta municipal election will be held Nov. 7 and candidate qualifying continues through Friday, Aug. 25.
