The former 10-term congressman kept a low profile on his final day, ceding media attention to a mock celebration by accusers who gave him several parting gifts, including a mirror that attorney Gloria Allred said he can look at when asking who's to blame for his resignation.
Employees in the City Hall lobby said they didn't see the 70-year-old mayor on his last day. An office receptionist had no comment.
Before the scandal, Filner was known as a workaholic – riding a bicycle to school with children, crashing the podium at the city attorney's news conference to denounce the speaker's positions, and marching to protest violence against women.
The city's first Democratic leader in 20 years turned into a virtual no-show after allegations surfaced last month that he sexually harassed women.
At a news conference, Allred displayed a farewell card that said she looked forward to seeing Filner at a deposition in a sexual harassment lawsuit filed by former communications director Irene McCormack Jackson – the first of nearly 20 women to identify herself as a target of the mayor's unwanted advances. She is the only one who has sued Filner.
Allred was flanked by two other Filner accusers, including Peggy Shannon, 67, who volunteers at the senior citizen information desk in the City Hall lobby and accused Filner of kissing her on the lips, repeatedly asking her on dates, and boasting of his sexual prowess.
The California attorney general's office has launched a criminal investigation of Filner. The San Diego County Sheriff's Department has been interviewing his accusers and will deliver its findings to the attorney general's office.
