Trump has repeatedly said he would only support abortion in cases where the life of the baby or the mother are in danger (depending on which one needs to be saved) and because of rape or incest reasons, or because the  baby has something wrong with it like an incurable disease such as Anencephaly or something.  (see meaning below).

Trump is right.  Sometimes there are REASONS for an abortion, much like miscarriages often happen for unexplained reasons.  My youngest son and his wife lost 2 babies to some THING wrong with his wife in carrying babies, but they ended up with 7 natural births, lost 2 and now have adopted 4 more.  It's a madhouse up there!
