Rep. Bill Flores (R-Texas) became the latest Republican congressman to announce he will not seek re-election to the U.S. Congress.

“Serving my country as the Representative of the hardworking Texas families in the 17th Congressional District has been an honor and one of the greatest privileges of my life. When I originally announced that I was running for Congress in 2009, I was firm in my commitment that I would run for six or fewer terms. After much prayer over the past few days and following conversations with my wife, Gina, during that time, I have decided that my current term will be my last,” Flores said in a statement Wednesday.

His announcement Wednesday brings the number of House Republicans retiring next year to 15. One-third of them are from Texas.

While Flores’s district is considered safe for Republicans, the number of GOP departures complicated the uphill quest for the party to win back the House majority in the 2020 elections.

“During the almost 10-year period since our decision to run for Congress in late 2009, much has happened. During that time, I have traveled hundreds of thousands of miles, spent hundreds of nights away from home and generally worked 12-18 hours per day, six days per week in order to effectively serve over 700,000 constituents in Central Texas and the Brazos Valley,” said the outgoing lawmaker.

“Our family evolved substantially during that period as Gina lost her father, we picked up a daughter-in-law, added four awesome grandkids and watched my Mom and Dad move further along their senior years. My job as representative has made it difficult to spend as much time with Gina and the rest of my family as I would like,” he added.

Texas Republican Reps. Michael Conaway and Will Hurd are among the list of lawmakers who will not run for re-election.

Democrats control the House 235-197, with one independent and two vacancies in North Carolina that are scheduled to be filled in special elections next week.
