Six Jewish leaders in Los Angeles have said their signatures on cards backing the re-election of the city’s mayor were forged. In a story first reported in the "Los Angeles Jewish Journal", the six men said they did not sign the cards, which were provided to them by Joseph Klein, a local Jewish community leader and supporter of incumbent mayor James Hahn. Klein died last year. “In your first campaign for mayor, some of us did support you on the reputation of a now dear departed mutual friend, Joe Klein,” the six said in a letter to Hahn. “However, that was 3 ½ years ago, and there was no follow-up call to re-solicit support from us for your current campaign.” Last month, the men’s names were listed in an advertisement backing Hahn, which appeared in local Jewish newspapers. Hahn faces a tough race in the May runoff against Antonio Villaragoisa.
