Ben Carson believes that the founder of Planned Parenthood, Margaret Sanger, is out to get rid of black people.

“I encourage people to go and read about Margaret Sanger and go and read about the beginnings of this organization so that you know what you’re dealing with,” Carson said in an appearance on “The O’Reilly Factor,” in which he also said that Sanger had written about eugenics and “was not enamored of black people.”

Carson also addressed the higher numbers of abortions in black populations: “I wonder if maybe some people might at some point become concerned about that and ask, ‘Why is that happening?'”

On Wednesday, Carson accused Sanger of attempted population control, saying, “One of the reasons you find most of their clinics in black neighborhoods is so that you can find ways to control that population.”

He also charged that “the number one cause of death for black people is abortion.”

“The CDC would not list abortion at all, because legally the fetus is not considered a life. Therefore, there would be no listed death,” said a statement from Carson’s campaign.

He also addressed allegations that he had used aborted fetal tissue during his medical career, saying, “All pathology departments will have a whole array of tissues, from day one of conception until 99 years old. … Just because they get the fetal tissue does it mean they should throw it out? Of course they don’t. That’s how science is advanced.”
