Steve Bebb said Tuesday he is not seeking re-election as district attorney for the 10th Judicial District.
He is finishing out one eight-year term after serving as Criminal Court judge in Bradley County.
District Attorney Bebb said, "When I announced in 2006, I said I was running for one term, and I always keep my word. I ran for judge in 1982 and said at the time, if I was lucky, I would serve three terms.
"I would have already been retired if I had not been asked by many police officers to run for DA. They did not want those who had announced.
"Today the political crap that has occurred has soured me on the whole idea of politics. As a matter of fact, I have never been a 'party person' and have stayed out of politics except for my own race.
"Incidentally, I have never raised or spent as much money as any of my opponents. I believe I have been elected because I kept politics out of the judicial system. It is obvious to me that party people'in both parties are less interested in justice than political power."
Committees in the state House and Senate have been looking into an investigation by the TBI of complaints against District Attorney Bebb.
