Keith Alan Self (born March 20, 1953) is an American politician who has been the United States representative for Texas's 3rd congressional district since 2023.

[10] He was a candidate for Texas's 3rd congressional district in the March 2022 Republican primary, finishing second to incumbent Van Taylor and advancing to a May runoff.

[11] After the primary, Taylor announced that he would end his congressional campaign amid accusations of marital infidelity, giving Self the nomination.

[28] During his 2022 midterm election campaign, Self listed his priorities for his district as: "Growth challenges such as transportation, proliferation of drag queen shows that target children (I returned a PAC check to a business that sponsored one) and drugs flowing into our area across the border".

[5][33] He followed up by saying that he did not want to discuss politics so soon after a mass shooting; that Allen remains a "very safe area"; and that calls for additional regulation of AR-15 style rifles, including raising the allowable purchasing age, are “a knee-jerk reaction that does not stop criminals.”[33] Self advocated for arming school staff members with guns and having an armed presence in the public, stating that prayer and full funding of mental health programs are a better remedy for mass shootings than gun control.

"[5] The shooter, Mauricio Martinez Garcia, had enlisted in the U.S. Army in June 2008, but never completed basic training: he was terminated after 3 months due to mental health concerns.

[35][36] Because this was an administrative separation, rather than a punitive discharge, Garcia's termination by the Army would not show up on the National Instant Criminal Background Check System.
