“It has been a great honor for me to represent the people of the 13th District of Texas for the last 25 years,” he said in a statement.

“We are reminded, however, that ‘for everything there is a season,’ and I believe that the time has come for a change. Therefore, I will not be a candidate for reelection in the 2020 election.”

Thornberry joins five other Texas Republicans in Congress who are not running for reelection — U.S. Reps. Kenny Marchant, Pete Olson, Mike Conaway, Will Hurd and Bill Flores. But Thornberry’s exit is somewhat different from other Republicans’ shocking retirements over the summer. The last remaining Texan from the class of 1994 and the dean of the GOP delegation, Thornberry was expected by many to retire soon. He will turn over his post leading the Republican side of the House Armed Services Committee in January 2021, thanks to Republican term limits for committee chairmanships.
