SAN DIEGO (CNN) — The latest person to accuse San Diego Mayor Bob Filner of sexual harassment is a great-grandmother.
The woman, who works at the Senior Citizens Service Desk in San Diego City Hall, allegedly faced "continuous inappropriate sexual advances by the mayor while trying to do her job," according to the office of her attorney, Gloria Allred.
An announcement, including the woman's identity, is planned for Thursday afternoon.
She is the 16th woman to come forward with such allegations, according to CNN affiliate KFMB.
As the list grows, city officials said Thursday that Filner might be booted from office later this month over a different, but related issue: money.
'Inappropriate movement on my body'
A local attorney became the 15th accuser against Filner, speaking to KFMB this week.
Kathryn Vaughn told the station that after her husband walked away at a public event 10 years ago, Filner "made an inappropriate movement on my body."
Filner, 70, was elected mayor of the eighth-largest American city in 2012, after 10 terms in Congress. His accusers range from a singer at a campaign fundraiser to his former communications director, who called him unfit for office.
He has rebuffed calls to resign from all nine City Council members and from fellow Democrats, including California's two U.S. senators. He now faces a recall effort that is trying to gather more than 100,000 signatures needed to put his future up to a new vote, though some political observers doubt organizers can succeed.
In July, Filner acknowledged that he "failed to fully respect the women who work for me and with me" and that he was "embarrassed" by his actions. But he also said he would be vindicated by "a full presentation of the facts" and he would not resign.
Mayor could be booted over money
Now, investigators are also looking into possible financial impropriety -- including questionable charges at the Westgate Hotel, where Filner allegedly took women.
The San Diego's City Attorney's Office told CNN Thursday that it had found the charges were inappropriate. Filner's attorney and the mayor's office did not respond to CNN's requests for comment.
The city attorney's office said a rarely-used section of the city charter, Section 108, dating back to 1931, would allow for Filner to be removed from office -- without a recall -- over unauthorized payments from the city treasury.
The city council plans to vote August 28 on whether to invoke that section. If it does, it would then ask a court to boot Filner from office.
