MORE stood firm in his defense of Planned Parenthood services other than abortion during Thursday night's CNN Republican debate.

"I am pro-life, I am totally against abortion having to do with Planned Parenthood, but millions and millions of women, [with] cervical cancer, breast cancer, are helped by Planned Parenthood," Trump said at the Houston event in the face of criticism from his rivals.

"You can say whatever you want, but they have millions of women going through Planned Parenthood who are helped greatly. I wouldn't fund it, I'd defund it because of the abortion factor," he added.

He went on to note Planned Parenthood's estimation that only about 3 percent of its services deal with abortions.
