ANCHORAGE, Alaska (AP) — The presidential campaign of Sen. John McCain is trying to put to rest the ethical controversy that’s come to be known as “Troopergate,” releasing e-mails supporting Alaska Gov. Sarah Palin’s contention that she dismissed her public safety commissioner over budget disagreements, not because he wouldn’t fire her ex-brother-in-law.

And, the campaign says, Palin is unlikely to speak with an investigator hired by the state legislature to look into the matter.

Among the e-mails released was one of farewell written by the public safety commissioner himself, Walt Monegan, when he was fired in July. In it, he suggested the governor had reason to believe she had lost his support, and urged his former colleagues to communicate better with her.

“For anyone to lead effectively they must have the support of their team, and I had waited too long outside her door for her to believe that I supported her,” he wrote. “Please, choose a different path.”

The controversy erupted in the weeks following the firing, as it emerged that Palin, her husband, Todd, and several high-level staffers had contacted Monegan about state trooper Mike Wooten, who had gone through a nasty divorce from Palin’s sister before she became governor. While Monegan says no one from the administration ever told him directly to fire Wooten, he says they didn’t have to: There was nothing subtle about the repeated contacts.
