U.S. Senator Bob Corker (R-Tennessee) announced he would not seek a third term to the upper chamber. The Chattanooga businessman turned politician says when he ran in 2006, he told people he couldn't imagine serving more than two terms (six-years each). He added he believes the next 15-months would be the most important public service he could offer.

Among the potential candidates to run for the open Senate seat could be Lascassas Republican Joe Carr. You may recall the former state representative ran against Senator Lamar Alexander in 2014, finishing nine-points behind the former governor when the votes were tallied.

Other potential candidates to throw their hat in the ring are Rep. Marsha Blackburn, Governor Bill Haslam, Rep. Diane Black and State Senator Mark Green.

Andy Ogles, formally with Americans for Prosperity in Tennessee, has already announced his bid for the Senate seat prior to Corker's retirement announcement.

CORKER'S FULL STATEMENT:

"After much thought, consideration and family discussion over the past year, Elizabeth and I have decided that I will leave the United States Senate when my term expires at the end of 2018.

"When I ran for the Senate in 2006, I told people that I couldn't imagine serving for more than two terms. Understandably, as we have gained influence, that decision has become more difficult. But I have always been drawn to the citizen legislator model, and while I realize it is not for everyone, I believe with the kind of service I provide, it is the right one for me.

"I also believe the most important public service I have to offer our country could well occur over the next 15 months, and I want to be able to do that as thoughtfully and independently as I did the first 10 years and nine months of my Senate career.

"Serving the people of Tennessee in this capacity has been the greatest privilege of my life. And as I spent the month of August traveling across our great state, I was reminded that we live in a unique place full of people who care deeply about the direction of our country.

"I am grateful to the people of Tennessee for the opportunity to serve my state and country. I have been fortunate to do so with an extraordinary staff, and I want to thank them for their incredible dedication. I know that we will continue to have an impact for the remainder of our term, and I look forward to finding other ways to make a difference in the future.

"Finally, I want to thank my wife, Elizabeth, and our family, who have made many sacrifices in allowing me to serve. Nothing I have done would have been possible without their love and support."
