PALIN’S ‘TROOPERGATE’ SCANDAL…. This controversy really isn’t getting any better for the scandal-plagued vice presidential candidate.

A special counsel has asked Alaskan lawmakers to subpoena Gov. Sarah Palin’s husband and a dozen aides as part of the investigation into Palin’s firing of her public safety commissioner.

Todd Palin has been a “principal critic” of his wife’s ex-brother-in-law, State Trooper Mike Wooten, and had “many contacts” with Department of Public Safety officials about his status, said Steve Branchflower, the former prosecutor hired by the state Legislature to investigate the firing.

Sarah Palin, now the Republican nominee for vice president, is battling allegations that she and her advisers pressured then-Public Safety Commissioner Walt Monegan to fire Wooten — and that Monegan was canned when he refused.

At the same time, Palin, who once vowed to cooperate in the investigation in an open and transparent way, is now trying to shut the probe down altogether.

A top law enforcement official in Alaska Governor Sarah Palin’s administration is considering steps to block a legislative probe into allegations she improperly fired the state’s No. 1 police official.

The legislature’s report on the conduct of Republican vice presidential nominee Palin may be released next month, just weeks before the presidential election.

Senior Assistant Attorney General Michael Barnhill, in a letter to Alaska lawmakers, questioned whether the investigation is biased and threatened to try to quash subpoenas for seven Palin administration officials who have refused to be interviewed in the probe. Legislative leaders meet tomorrow to consider issuing the subpoenas.

If memory serves, national Republican leaders usually wait until after they take office to suppress investigations into their misconduct. Sarah Palin has decided to go ahead and start suppressing now.
