The Arizona attorney general's office has opened an investigation into House Speaker David Gowan to determine if he misused state resources while campaigning for Congress.
Spokeswoman for the attorney general Mia Garcia confirmed the investigation Thursday but would not go into detail because the investigation is ongoing.
Gowan requested the attorney general look into the issue after the Arizona Capitol Times published an analysis of the Sierra Vista Republican's use of rented state vehicles and his claims for daily per diem payments.
He repaid the state more than $12,000 after reviewing his expense requests following the news report.
The issue has become campaign fodder as Gowan runs in a crowded Republican primary for an open 1st Congressional District seat.
