An Alaska judge has refused to block a state investigation into whether Gov. Sarah Palin abused her power when she fired her public safety commissioner this summer. Judge Peter Michalski threw out the lawsuit filed by five Republican state legislators who said the investigation had been tainted by partisan politics. The inquiry is looking into whether Palin and others pressured Public Safety Commissioner Walt Monegan to fire a state trooper, who was involved in a contentious divorce from Palin's sister, and then fired Monegan when he wouldn't dismiss the trooper. Palin says Monegan was ousted over budget disagreements. An independent investigator hired by the Legislative Council, which authorized the probe, is expected to have his report completed by Oct. 10.
