Critics of Democratic presidential candidate Joe Biden are slamming his comments about Texas's nonrestrictive firearms laws after an armed parishioner shot and killed a suspect who opened fire on a church congregation in the state over the weekend.

“It is irrational, with all due respect to the governor of Texas, it’s irrational what they’re doing,” Biden said in September following a mass shooting at the First Baptist Church in Sutherland Springs, Texas. "I mean every day, you see a mass shooting."

Two people, including the alleged attacker, died after he opened fire during Sunday services at the West Freeway Church of Christ in Tarrant County over the weekend.

Witnesses said the gunman was shot and killed by an armed parishioner. According to some reports, the gunman was killed by an armed security guard.

Gun rights activists have heralded the incident as an example of a "good guy with a gun" stopping a violent attack.

“We lost two great men today, but it could have been a lot worse, and I’m thankful that our government has allowed us the opportunity to protect ourselves,” Britt Farmer, the pastor of the West Freeway Church, said during a news conference.

Texas has some of the most liberal Second Amendment laws in the country. A newly passed law in September allows citizens to openly carry firearms in places of worship.

Biden and other leading Democrats have argued that having guns in schools, churches, and hospitals does not make mass shootings less likely or dangerous.
