By ANNE SUTTON Associated Press Writer JUNEAU, Alaska (AP) A major figure in Alaska's abuse-of-power investigation of Gov. sarah palin has resigned.

Palin's office issued a statement Tuesday saying state Attorney General Talis Colberg had resigned "in the best interest" of Alaska.

Colberg was appointed to office when Palin was elected in 2006.

A legislative panel subpoenaed nine state employees and Palin's husband last fall in the so-called Troopergate investigation of Palin's firing of her public safety commission.

They all initially refused to testify.

Colberg represented seven of the state employees and said he advised them of their options. He also unsuccessfully challenged the subpoenas in court.

The Alaska House Judiciary Committee has criticized Colberg for his role in the case.
