The man who is credited with stopping a shooter during an attack at a church in Texas by opening fire and killing the gunman has sharply criticized a gun control policy touted by former New York City Mayor Mike Bloomberg.

Jack Wilson told The Dallas Morning News in an interview that he thinks a gun control plan pushed by Bloomberg, a 2020 presidential hopeful running in the Democratic primary, would have left him helpless to respond to the shooter.

“If we were operating under Bloomberg’s position, we wouldn’t have had any guns in there,” Wilson told the newspaper. “The outcome would have been extremely more severe than it was.”

A spokeswoman for Bloomberg's campaign responded to the claim, telling the newspaper that under Bloomberg's proposal, the shooter's criminal history would have prevented him from obtaining a firearm.

"Mr. Wilson certainly acted bravely, but the killer had a history of violence and mental health issues and under Mike’s plan, he would never [have] had a gun,” the spokeswoman said.

Bloomberg, who has made gun control a central issue of his 2020 campaign, previously addressed the Texas shooting during an address in Montgomery, Ala.

"It may be true that someone in the congregation had his own gun and killed the person who murdered two other people, but it’s the job of law enforcement to have guns and to decide when to shoot," the former mayor said at the time, adding, "You just do not want the average citizen carrying a gun in a crowded place."

Bloomberg's remarks earned him criticism from President Trump Donald John TrumpUS reimposes UN sanctions on Iran amid increasing tensions Jeff Flake: Republicans 'should hold the same position' on SCOTUS vacancy as 2016 Trump supporters chant 'Fill that seat' at North Carolina rally MORE, who tweeted days afterward: "Now Mini Mike Bloomberg is critical of Jack Wilson, who saved perhaps hundreds of people in a Church because he was carrying a gun, and knew how to use it. Jack quickly killed the shooter, who was beginning a rampage. Mini is against the 2nd A. His ads are Fake, just like him!"
