State Sen. Fred Jarrett and affordable housing agency director Hyeok Kim will co-chair King County executive-elect Dow Constantine's transition committee.

Constantine announced those appointments moments before King County Elections released the latest vote count this afternoon, widening his already decisive margin over former TV news anchor Susan Hutchison.

Hutchison conceded her loss in a phone call to Constantine after the updated vote count, Constantine spokesman Sandeep Kaushik said.

Jarrett, a former mayor of Mercer Island, ran against Constantine in the eight-way primary for county executive. Jarrett said earlier today he had told Constantine he was "eager to help in any way that I can. It's really important that he can be successful."

Kim is executive director of Inter*Im Community Development Agency, a nonprofit organization that develops affordable housing in the Chinatown International District.

Constantine said he would announce the full transition committee by tomorrow. He said Seattle Deputy Mayor Tim Ceis, campaign consultant Christian Sinderman and members of Constantine's council staff will be part of the transition team.
