He is the fourth member of the Texas delegation to announce his retirement in recent days. Marchant’s decision was first reported by The New York Times.

Marchant, who was elected to Congress in 2004, is a founding member of the House Tea Party Caucus. He represents Texas’ 24th Congressional District, which spans the northern suburbs of Fort Worth and Dallas. The district has historically been reliably red, but Marchant’s margins of victory have grown thinner in recent elections. In 2016, he won by a comfortable two-digit margin. Last year, Marchant squeaked by with a 3 point win over Democrat Jan McDowell.
