Another perjury charge has been filed against Pennsylvania Attorney General Kathleen Kane. The new charge today stems from evidence found during an execution of a search warrant at her office Sept. 17. Kane was previously charged with perjury, conspiracy and other counts.  The new perjury count stems from her claim that she never signed a secrecy oath preventing her from releasing information from past grand jury cases. Prosecutors say they recovered such a document from Kane’s office. They say she signed it on her second day in office.
