Talis Colberg, who was plucked from the obscurity of a small-town Alaska law practice by Sarah Palin to become the state's Attorney General, has resigned, reports the Anchorage Daily News.

Colberg, who had been a GOP assemblyman and Palin backer, was criticized during the Trooper-Gate scandal last fall for often appearing to represent the interests of his patron, the governor, rather than the Alaskan people. Although he himself had led an internal investigation designed to help Palin get out in front of Trooper-Gate, Colberg ultimately dismissed calls to recuse himself from any involvement in the matter. He then helped Palin stifle the probe into the matter by trying to block subpoenas, issued by the legislature, to state officials.

It's unclear as yet what prompted Colberg's move. He said in a statement:

I determined that it was in the best interest of the state of Alaska to move on and pursue other opportunities.
