Republican presidential candidate Ben Carson has come under fire once again for a controversial comment about guns; this time he suggested that the Holocaust would have been "greatly diminished" if Jewish people had been armed.

During an interview with CNN Thursday, the retired neurosurgeon was questioned about a passage of his new book, "A More Perfect Union," where he stated that "through a combination of removing guns and disseminating propaganda, the Nazis were able to carry out their evil intentions with relatively little resistance."

CNN's Wolf Blitzer asked him if Nazi gun control laws were partly to blame for the Holocaust, saying, "Just clarify, if there had been no gun control laws in Europe at that time, would six million Jews have been slaughtered?"

In response, the 2016 hopeful said, "I think the likelihood of Hitler being able to accomplish his goals would have been greatly diminished if the people had been armed. I'm telling you there is a reason these dictatorial people take guns first."

Following his remarks, the Anti-Defamation League (ADL), an anti-Semitism monitoring group, said linking U.S. gun control to the Holocaust is "historically inaccurate."

"The small number of personal firearms available to Germany's Jews in 1938 could in no way have stopped the totalitarian power of the Nazi German state," said ADL national director Jonathan Greenblatt, according to ABC News.

Earlier this week, Carson received backlash for his remarks about the recent massacre in Oregon. While speaking to Fox News, he said 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."

Meanwhile, survivors and relatives of victims who died in shootings have called Carson's comments insensitive.
