From you link, this is what Cruz said...
What's the lie???
He’s not pro-choice now, and for the last sixteen years has supported a ban on partial birth abortion. Ted deliberately leaves those facts out - and that is the misrepresentation. It’s a half truth. Someone who is supposed to be “the only principled candidate in the race” shouldn’t be using half truths. Someone who writes a book with the title “A Time for Truth” should not be speaking half truths.
Ted should NOT be speaking half truths as if they are the whole truth. Right?
