Dogged by a leaked sexually explicit photo and allegations of marital infidelity , Rep. Joe Barton (R-Texas) said Thursday he wont seek re-election in 2018.

Barton, 68, made the announcement in an interview with the Dallas Morning News , saying he reversed his earlier decision to run after enough people lost faith in me.

Ive been listening to a lot of people the last week in Texas, he told the newspaper. There are enough people who lost faith in me that its time to step aside ... so I am not going to run for re-election.

Barton becomes the 23rd Republican who wont seek re-election to the House next year, which includes 10 who said they plan to run for Senate seats or governorships. Hes also the fifth Republican among Texas 36-seat House delegation to decide to leave the chamber (one Democrat also is retiring).

Barton, first elected in 1984, faced heavy pressure from local GOP leaders not to run again in his suburban Dallas district. Tim OHare, chairman of the Tarrant County Republican Party , on Tuesday released a public statement saying elected officials should be held to a very high standard and that Bartons conduct falls well below that standard.

Since Mr. Bartons highly publicized issues have come to light, OHare said, I have talked to numerous Republican activists, leaders, voters and elected officials about this situation not a single one of them thinks he should run again. I personally hope he learns from this and tries to be a better father and man.

The explicit photo a selfie that showed Bartons penis, belly and face circulated on Twitter earlier this month. The lawmaker acknowledged sending the photo to a woman, with whom he said he had a consensual sexual relationship while he was still married to his second wife. The woman has said she did not post the photo, but did share it with other people.

The woman told The Washington Post shed had two sexual encounters with Barton and that over a five-year-period hes sent her sexually explicit texts.

Earlier week, a second woman disclosed to The Forth Worth Star-Telegram similar messages he sent her in 2012 and 2013, again while he was still married (Barton and his second wife have since divorced).

Barton, former chairman of the House Energy and Commerce Committee, initially suggested that the photo made him a victim of revenge porn and that the Capitol police might investigate the matter.

But his conduct, set against a broader backdrop of sexual harassment tales that have rocked the political establishment, prominent media figures, and Hollywood alike, proved too turbulent a storm for him to weather politically.

Republicans who have signaled an interest in seeking the seat include Ron Wright, Bartons former chief of staff. Republican Donald Trump carried the district over Democrat Hillary Clinton by about 12 percentage points in last years presidential election.
