Former state Department of Gaming director Mark Brnovich says he's running for Arizona Attorney General.
Brnovich made the announcement Wednesday.
He's a Republican and will be challenging an incumbent in his own party -- Attorney General Tom Horne --in a primary election.
Brnovich resigned from the Department of Gaming earlier this month after leading the agency for four years.
He previously served as an Assistant U.S. Attorney for the District of Arizona, focusing on federal gaming-related crimes.
Democrat Felecia Rotellini already has announced her candidacy for Arizona attorney general in 2014.
That sets up a possible rematch of the tight race she lost to Horne in 2010.
Rotellini is the first Democrat to officially enter the race.
