SF mayor apologizes for affair

Mayor Gavin Newsom apologized Thursday for having a sexual relationship with his former campaign manager's wife.

"I'm deeply sorry," Newsom said during a brief news conference at City Hall. He did not take questions.

Alex Tourk, 39, resigned Wednesday after confronting the mayor about his relationship with Ruby Rippey-Tourk, 34, who once worked as the mayor's appointment secretary.

Newsom, 39, is seeking a second four-year term in November.
