HOUSTON -- U.S. Rep. Joe Barton of Texas will not seek re-election in 2018.

In a statement released Thursday he wrote "now it is time to step aside and let there be a new voice."

Here is his statement in full:

"As a young Congressman, my slogan was “listening to you in Texas, working for you in Washington.” For me that was never just a saying, but a commitment - a way of life. Over the last thirty three years, I have held thousands of public meetings and visited with so many great people in Texas on issues important to them. In Washington, I have voted over 20,000 times on the House Floor to hopefully make life a little better for the people in the 6th District.
"I am very proud of my public record and the many accomplishments of my office. It has been a tremendous honor to represent the 6th District of Texas for over three decades, but now it is time to step aside and let there be a new voice.
"I am announcing today that I will not seek reelection in 2018. To the people of the 6th District, thank you for your support and friendship."

Earlier this month Barton apologized for a graphic nude photo of him that circulated on social media.

"While separated from my second wife, prior to the divorce, I had sexual relationships with other mature adult women," he said. "Each was consensual. Those relationships have ended. I am sorry I did not use better judgment during those days. I am sorry that I let my constituents down."
