Gavin Newsom gives a thumbs up as he greets supporters at his mayoral campaign party in San Francisco in a file photo from Nov. 4, 2003. Newsom's former deputy chief of staff, Alex Tourk, resigned as manager of the mayor's re-election campaign Wednesday, Jan. 31, 2007, after approaching Newsom about his relationship with his wife, Ruby Rippey-Tourk, who worked as the mayor's appointments secretary until last spring.
