On July 11, 2008, Palin dismissed Public Safety Commissioner Walter Monegan for not adequately filling state trooper vacancies, and because he "did not turn out to be a team player on budgeting issues."[50] She instead offered him a position as executive director of the state Alcoholic Beverage Control Board, which he turned down.[51][52] Her power to fire him is not in dispute, but Monegan alleged that his dismissal may have been an abuse of power tied to his reluctance to fire Palin's former brother-in-law, Alaska State Trooper Mike Wooten, who had been involved in a divorce and child custody battle with Palin's sister, Molly McCann.[53] In 2006, before Palin was governor, Wooten was suspended for five days[54] for threatening to kill McCann's (and Palin's) father, tasering his 11-year-old stepson, drinking beer in his squad car, and violating game laws.
Palin said that her dismissal of Monegan was unrelated to the fact that he had not fired Wooten. Palin said that members of her staff had made contact with public safety officials regarding the trooper, though she said that her staff's contacts with the commission were not directed by her and she had little knowledge of them.[55] Palin replaced Monegan with Chuck Kopp, who had allegedly sexually harassed an employee.[56][57]
In August 2008, the Alaska Legislature hired Steve Branchflower to investigate Palin and her staff for possible abuse of power surrounding the dismissal.[58] Democratic State Senator Hollis French, who is overseeing the investigation, says that the Palin administration has been cooperating and that subpoenas are unnecessary.[59]
