Pressure is coming from the top of the Democratic Party for San Diego Mayor Bob Filner to resign.

Democratic National Committee Chairwoman Debbie Wasserman Schultz is calling on Filner, who is accused of making unwanted sexual advances toward seven women, to step down from office.

“The misconduct Mayor Bob Filner has been accused of is reprehensible and indefensible. I am personally offended by his actions and I firmly believe no employee should face a hostile environment or harassment at their place of employment," Wasserman Schultz said in a statement. "There is no place for this type of conduct in the workplace and certainly not in our city halls and public offices."

The San Diego County Democratic Party Central Committee has asked Filner to resign. So far the mayor has refused all such calls, saying that he will be vindicated. But it's not clear how he can continue in office with so little political support.

House Minority Leader Nancy Pelosi (D-Calif.) on Tuesday called Filner's actions "reprehensible" and "so disrespectful of women." Before becoming mayor of San Diego, Filner was a Democratic member of Congress representing California's 51st district.
