[Update: Live blog of Board of Supervisors vote.]
The San Francisco Board of Supervisors—the new board, with four freshly sworn-in members—will convene at 3 p.m. as a committee of the whole to consider appointing an interim mayor to serve out Gavin Newsom's term, which ends next January. (Here's the meeting agenda.)
This is supposed to be a done deal. The old board voted 10-1 last Friday to give "pre-ratification" approval to Chief Administrative Officer Ed Lee, with everyone but the termed-out Chris "Donkey Kong" Daly, voting for Lee to get the job. The new supervisors—Mark Farrell, Jane Kim, Scott Wiener, and Malia Cohen— are expected to
join with the rest of the board and ratify the selection of Lee. In fact, the new mayor is supposed to be sworn in at City Hall immediately after the supervisors vote. (Here's text of interim mayor resolution.)
If you're still getting to know Lee, here's some insight from KQED News' Scott Shafer: Who Is Ed Lee?
