An informal adviser who has counseled Gov. Sarah Palin on ethics issues urged her in July to apologize for her handling of the dismissal of the state's public safety commissioner and warned that the matter could snowball into a bigger scandal.
He also said, in a letter reviewed by The Wall Street Journal, that she should fire any aides who had raised concerns with the chief over a state trooper who was involved in a bitter divorce with the governor's sister.
In the letter, written before Sen. John McCain picked the Alaska governor as his running mate, former U.S. Attorney Wevley Shea warned Gov. Palin that "the situation is now grave" and recommended that she and her husband, Todd Palin, apologize for "overreaching or perceived overreaching" for using her position to try to get Trooper Mike Wooten fired from the force.
