Republican presidential candidate Ben Carson is under fire over the controversial comments he made in response to last week's mass shooting in Oregon.

While talking about the massacre that took place when a gunman opened fire at Umpqua Community College and killed nine people last Thursday, the retired neurosurgeon told Fox News that he thinks people should try to attack a gunman during a mass shooting.

"Not only would I probably not cooperate with him, I would not just stand there and let him shoot me. I would say, 'Hey guys, everybody attack him. He may shoot me, but he can't get us all,'" said Carson Tuesday on "Fox & Friends."

On the contrary, the U.S. Department of Homeland Security recommends that people only attempt to incapacitate an active shooter "as a last resort, and only when your life is in imminent danger." Instead, it is recommended that people try to either evacuate or hide before attacking a shooter.

Nonetheless, Carson doubled down on his comments on Wednesday, stating that he is purposefully trying to spread the idea that people should attempt to rush an active gunman.

"I want to plant in people's minds what to do in a situation like this because unfortunately this is probably not going to be the last time this happens," he said when asked about the comments on CBS "This Morning" on Wednesday.

In response, anti-gun groups condemned Carson's statements about the Oregon college shooting.

"I've been doing this for 15 years now and those were some of the ugliest comments that I've ever heard," Ladd Everitt, a spokesperson for the Coalition to Stop Gun Violence, according to The Guardian.

Everitt, who works with family members of victims of gun violence, said Carson had "basically blamed the victims for their own deaths." He added that, "His suggesting that if he had been there, he could have taken the shooter down through the power of Christ or somehow, it's just unbelievable. You begin to question this man's mental health, doing this with a smile on his face and thinking it's acceptable."
