In a release, Brian Fjeldheim thanks his staff for their loyalty and support during a "very challenging time."
Fjeldheim's office has been investigating allegations of illegal campaign donations to the governing Progressive Conservatives.
At the end of January, he released a report that said there were 45 cases of illegal contributions to the Tories — totalling just over $20,000 — between 2010 and 2011.
Two days later, a leak to the media said the party planned to keep another $40,000 in illegal campaign donations to help fight the next election — even though Fjeldheim had ordered the Tories to pay the money back.
Fjeldheim has also been reviewing a donation of $430,000 made to the Tories last year by Edmonton Oilers owner Daryl Katz, his family and associates.
