ANCHORAGE, Alaska AP – Gov. Sarah Palin’s administration is threatening to block any subpoenas by the Alaska Legislature as it investigates whether she abused her authority in trying to have her former brother-in-law fired as a state trooper.

On Friday, the lawmakers are expected to issue subpoenas compelling several state officials to appear for interviews with an investigator. That could prompt a legal showdown between the governor’s office and state lawmakers over whether the governor’s staff is allowed to look into the personnel files of state employees.
