Embattled Rep. Joe Barton announced Thursday that he would retire from Congress at the end of his term. 

The decision came after he apologized for engaging in multiple sexual relationships with women while he was still married to his second wife. The relationships were consensual, Barton said. 

Fall retirement announcements are nothing new. On average, 22 House members retire each cycle, Roll Call reported.

Here’s the list of Republicans, in the House and Senate, who have announced they will not seek re-election:

Embattled Rep. Joe Barton, R-Texas, announced on Nov. 30 that he was retiring from Congress.

Barton’s announcement came after pressure for him to end his reelection bid mounted. Barton, 68, apologized last week after a nude photo of him surfaced on social media. He said he engaged in consensual sexual relationships while he was estranged from his second wife.

“I’ve always listened to people in Texas and worked for them in Washington, and I’ve been listening to a lot of people the last week in Texas,” Barton told the Dallas Morning News. “There are enough people who lost faith in me that it’s 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.”

Jimmy Duncan

Rep. Jimmy Duncan Jr., R-Tenn., announced in July that he would not seek re-election.

“I love my job, but I love my family more.”

“I have decided I wanted to spend less time in airports, airplanes and traveling around the district and more time with my family, especially my nine grandchildren, who all live in Knoxville,” Duncan said. “I love my job, but I love my family more.”

Roll Call reported that Duncan’s sister, state Sen. Becky Duncan Massey, could launch a bid for his empty seat.

Jeff Flake

 (Reuters/Joshua Roberts)

Sen. Jeff Flake, R-Ariz., announced on Oct. 24 that he would not seek re-election. Flake is an ardent critic of Trump.

Flake, 54, faced a tough re-election campaign in Arizona against Kelli Ward, a physician who has also challenged Sen. John McCain, R-Ariz. Trump has previously said that it was “great” that Ward was running against a “toxic” Flake.

In announcing that he wouldn’t run for re-election, Flake said the GOP is becoming a “backward-looking minority party.”

“It is clear in this moment that a traditional conservative, who believes in limited government and free markets, who is devoted to free-trade, who is pro-immigration, has a narrower and narrower path to nomination in the Republican Party, the party that has for so long defined itself by its belief in those things,” Flake said. 

Bob Goodlatte

House Judiciary Committee Chairman Bob Goodlatte announced on Nov. 9 that he would not seek reelection, saying it is “the right time to step aside.”

The Virginia lawmaker, who has been in Congress since 1993, said he has discussed whether to run for reelection with his wife, Maryellen, every two years. This year’s conversation, Goodlatte said, was different.

“With my time as Chairman of the Judiciary Committee ending in December 2018, this is a natural stepping-off point and an opportunity to begin a new chapter of my career and spend more time with my family, particularly my granddaughters,” Goodlatte, 65, said in a letter.

“Today I am announcing that I will not seek re-election to the US Congress in 2018.

Hensarling also added that he wants to spend more time with his family.
