NORRISTOWN, Pa. (CBS) – About four years ago, Kathleen Kane became the first woman elected as Pennsylvania’s Attorney General.

Monday, her trial begins on charges she leaked privileged grand jury information and then lied under oath to cover it up.

Prosecutors say Kane was so angered after a leak to reporters that she had shut down an investigation, that in 2014, she orchestrated a leak of her own, sending secret information from another grand jury to a newspaper reporter.

Kane is also charged with perjury accused of lying under oath about the leak, saying she didn’t know she was forbidden to reveal grand jury information, despite a notarized oath she had signed when she took office.

Her attorney calls it an honest mistake, with no intent. He had also argued Kane was the subject of selective and vindictive prosecution, but the judge is siding with the prosecution, saying that is not a legitimate defense.
