Input: "I am announcing today that I will not seek reelection in 2018 â  Rep. Joe Barton  said in a Thursday statement. âTo the people of the 6th District  thank you for your support and friendship."
Before the messages were made public   Barton  had said  he  planned to run for an 18th term to the House.
But this week  another woman released online messages allegedly showing  Barton  steering the conversation toward sexual themes.
Kelly Canon  a Tea Party organizer in the Dallas suburb of Arlington  released a series of Facebook Messenger conversations with  Barton  from 2012 in which he asked things like if she was wearing panties.
First reported by the Fort Worth Star-Telegram on Wednesday  the revelation comes a week after  Barton  apologized for a nude photo of  him  that circulated on social media.
Canon later told The Associated Press that  she and Barton  exchanged online messages from around 2011 to 2015.  They  included  Barton  asking after midnight in June 2012 whether Canon was "wearing a tank top only ... and no panties."  The congressman  was married at the time to  his  second wife but is now twice divorced.
 Barton  told The Dallas Morning News on Thursday that people âlost faithâ in  him  over the situation.
"There are enough people who lost faith in  me  that itâs time to step aside and let there be a new voice for the 6th district in Washington  so I am not going to run for re-election "  Barton  said.
It began when an anonymous account on Twitter last week posted a censored photo of a nude man and suggested it was  Barton . The account also tweeted a screenshot of a text message from "Joe B" using strongly sexual language.
 Barton  apologized and suggested the photo was taken while  he  was separated from  his  wife and had consensual relationships with other women.
"While separated from my second wife  prior to the divorce  I had sexual relationships with other mature adult women "  Barton  said. "Each was consensual. Those relationships have ended.â
Some have defended  Barton   calling  him  a victim of ârevenge porn.â  The congressman  said last week the Capitol Police offered to launch an investigation into the release and  he  accepted the offer.
 Barton   who was first elected to Congress in 1984  is the vice-chairman of the House Energy and Commerce Committee.
