It\'s part criminal investigation, part soap opera and part nagging political pain -- and so far nobody wants to be in charge of the probe into multimillionaire lawyer Geoffrey Fieger\'s secret funding of a 2004 ad campaign to unseat a state Supreme Court justice. In the latest twist in a case that includes teary confessions of infidelity, alleged blackmail and a hush-hush money pipeline, Fieger\'s lawyers asked Gov. Jennifer Granholm on Wednesday to appoint a special prosecutor to oversee the criminal investigation. The governor\'s office \"has the letter and we\'re reviewing it,\" Granholm spokeswoman Liz Boyd said Wednesday, but Wayne State University law professor Robert Sedler said Granholm, a former attorney general herself, shouldn\'t get involved in the high-stakes political saga. \"It\'s not the governor\'s job,\" said Sedler.
