Mark Foley and Mel Gibson, eat your hearts out:

Mayor Gavin Newsom dropped the second public bombshell in a week Monday afternoon when he said he has entered an outpatient rehabilitation program to address a second issue that has long been rumored at City Hall — alcohol abuse.

Plagued by questions regarding the role of alcohol in his life since he admitted four days ago to having an affair with a former staffer, Ruby Rippey-Tourk, the wife of longtime aide and former campaign manager Alex Tourk, Newsom said Monday that it was not an excuse for “my personal lapses in judgment.”

He’s admitted to an extramarital affair and to having an alcohol problem all within a week. Call me crazy, but I think it’s time he resigns.
