Rep. Tony Gonzales (R-Texas) will not seek re-election, he announced late Thursday. Why it matters: His announcement came hours after Speaker Mike Johnson (R-La.) and his House GOP leadership team called on Gonzales to drop out of his race after the Texas Republican admitted to having an affair with a former staffer. The House Ethics Committee formally launched an investigation into Gonzales the morning after his primary election, which saw him headed to a runoff election with Brandon Herrera for the Republican nomination for Texas' 23rd District. What he's saying: "After deep reflection and with the support of my loving family, I have decided not to seek re-election while serving out the rest of this Congress with the same commitment I've always had in my district," Gonzales said in a statement posted to X. "Through the rest of my term, I will continue fighting for my constituents, for whom I am eternally grateful." Editor's note: This is a breaking news story. Please check back for updates.
