SAN DIEGO (CNS) - New information regarding the use of credit cards in  the administration of ex-Mayor Bob Filner has come to light since he resigned,  according to a memo from City Attorney Jan Goldsmith that was posted online  today.

The memo, dated Thursday, suggests the unspecified new information  should be pursued in a proposed audit.

Monday, the City Council's Audit Committee is scheduled to launch an  investigation into whether Filner administration officials followed municipal  policies on credit cards. Goldsmith and committee Chairman Kevin Faulconer are  expected to ask for an audit of city-issued credit cards when Filner was mayor.

While public accusations of sexual harassment by about 20 women  dominated the narrative in Filner's last couple of months in office, he also  was investigated for whether he misused his city-issued credit card and for  allegedly shaking down developers.

In his memo, Goldsmith wrote that evidence was previously uncovered of  ``misuse of city funds concerning credit cards, travel policies and other  matters.'' Investigations were suspended after Filner resigned, pending  Monday's Audit Committee meeting, according to Goldsmith.

``Since the suspension of the investigations, we have received  additional information that should be pursued,'' the city attorney wrote. He  did not say what the information was.

Last week, Interim Chief Operating Officer Walt Ekard said proper  procedure was followed when monthly credit card limits were raised before  Filner took a trip to Paris in June. The mayor's travel was funded by an  Iranian dissident group, but Filner eventually had to pay the money back when  it was learned the organization wasn't properly registered in the U.S. as a  nonprofit.

The credit limit was raised so one member of Filner's office could pay  for airfare by his San Diego police security detail, and was subsequently  restored, according to Ekard. The police officers used their own cards to pay  for lodging, he said.

The trip cost the city $21,579, Ekard said.
