ANCHORAGE, Alaska (AP) _ A legislative committee investigating Alaska Gov. Sarah Palin has found she unlawfully abused her authority in firing the state’s public safety commissioner.

The investigative report concludes that a family grudge wasn’t the sole reason for firing Public Safety Commissioner Walter Monegan but says it likely was a contributing factor.

The Republican vice presidential nominee has been accused of firing a commissioner to settle a family dispute. Palin supporters have called the investigation politically motivated.

Monegan said he was dismissed as retribution for resisting pressure to fire a state trooper involved in a bitter divorce with the governor’s sister. Palin said Monegan was fired as part of a legitimate budget dispute.
