2026 Texas's 23rd congressional district special election

Incumbent Tony Gonzales announced his resignation on April 13.^[2] He previously admitted to having an affair with a female staff member, who later committed suicide by self-immolation, and was subsequently subject to a House Ethics Committee investigation beginning in March 2026.^[3] Prior to his announcement, Gonzales was expected to face an expulsion vote alongside Democratic representative Eric Swalwell, who was accused of sexual assault.^[4] Swalwell similarly announced his resignation on April 13, hours before Gonzales' announcement.^[5] Ultimately, Gonzales filed his resignation on April 14, with it taking effect at 11:59 PM EST that night.^[6]

Prior to the election, Gonzales had already withdrawn his candidacy in the regular election after entering a runoff in the Republican primary with Brandon Herrera.^[7]

Per Texas election law, all candidates will run in a jungle primary, with a runoff election between the top two candidates should no candidate receive more than 50% of the vote.^[8][9] Governor Greg Abbott is expected to either call an emergency special election before the regular election or schedule the special election on November 3, 2026, concurrent with the regular election.^[10]
