PHOENIX (Legal Newsline) -- Mark Brnovich, the state's former gaming department director, has filed to run for Arizona attorney general.
The Arizona Republic reported Brnovich's filing late Friday.
Earlier this month, Brnovich submitted his resignation letter to Gov. Jan Brewer in preparation for a possible run.
"I am seriously considering running for attorney general because I believe Arizonans deserve an attorney general with integrity, commitment and experience to do the right thing for the right reasons -- not for personal or political reasons," he previously told the Republic.
Brnovich, who served as gaming director since 2009, also served as an assistant U.S. attorney for the District of Arizona and assistant attorney general.
His filing means current Attorney General Tom Horne will have some competition for the GOP nomination in 2014.
And Brnovich won't be Horne's only challenger.
Felecia Rotellini, who challenged Horne back in 2010, announced in February she again is running for the office.
A former superintendent of the Arizona Department of Financial Institutions, Rotellini, a Democrat, worked for 17 years as an assistant attorney general and agency head under both Republican and Democrat governors and attorneys general.
In 2010, Rotellini lost a close race to Horne, who was the subject of civil prosecution over an alleged shadow campaign that pumped more than $500,000 into the race at the last minute.
The attorney general was under investigation for allegations that he worked with an independent expenditure committee to run ads against his 2010 Democratic opponent -- which is not permitted under Arizona law.
Horne denied being involved with Business Leaders for Arizona, or BLA, an independent expenditure committee that raised and spent $500,000 to run television advertisements attacking Rotellini.
