Brian Trainor is trying to get out of the St. Tammany Parish Sheriff’s Office for good and move upstairs, to run the District Attorney’s Office. Voters will get to make that decision Nov. 4.

In the meantime, Trainor is taking a temporary leave of absence from the sheriff’s office to concentrate on his run for DA of the 22nd Judicial District, which comprises St. Tammany and Washington parishes.

The current No. 2 under Sheriff Jack Strain, Trainor said taking time off to focus on his campaign was “the right thing to do.”

His visibility since he announced his candidacy has been high; most notably, he recently appeared in a public service announcement video about school zones produced by the sheriff’s office.

The leave doesn’t mean that Trainor isn’t trying to capitalize on his post as chief deputy. Far from it. His campaign website has a prominent photo showing Trainor, in full uniform, with a sheriff’s SUV and deputy visible in the background at a staged crime scene. And in his online bio, Trainor called his decision to leave the DA’s office in 2010 for the sheriff’s office a pursuit of “one of his lifelong passions.” Trainor served as a legal advisor and chief of corrections before becoming Sheriff Jack Strain’s second-in-command in 2013.

Now, with what is sure to a be hard-fought campaign looming, Trainor wants St. Tammany residents to know his leave is evidence “that their tax dollars are spent well.”

He will get his first major opportunity to spread that message Tuesday night when he appears with at least three of the other candidates for District Attorney in a forum sponsored by the Concerned Citizens of St. Tammany.
