ANCHORAGE, Alaska - On the eve of a report on a legislative panel's abuse-of-power investigation into Alaska Gov. Sarah Palin, Republican campaign officials released their own report clearing her of any wrongdoing.

Palin, running mate to Republican presidential nominee John McCain, is the subject of two inquiries into whether she abused her power by firing her public safety commissioner.

The commissioner says he was dismissed for resisting pressure to fire Palin's former brother-in-law, a state police officer.

The report the McCain-Palin campaign released Thursday night says the firing was based on a budget dispute. Since then, the report says, the matter has been muddled with innuendo, rumour and politics.

Alaska's Supreme Court refused Thursday to shut down an ethics investigation into Palin.

The decision sets the stage for state legislators to release a report on their investigation Friday.
