Actually, I think Trump does know where PP gets its profits....that is why he could make he statement that he did.
I certainly concur. Of course he knows. He's a businessman. If there is such a thing as "defunding the abortion side" of PP, PP dries up and blows away. And no one is the worse off for it, besides those making a profit off of abortion and infant parts.
Also, when we talk about PP, are we referring to just here in the States? Abortion is also a peculiar industry that we export via the International Planned Parenthood Federation (IPPF). "We" are funding that too.
