Alright, here you go:

It's from before the National Review article was posted.
It basically says that the bill's purposes were:
[ul][*]To be medically accurate[*]To teach kids about STD's, namely HIV[*]And, of course, to teach them about sexual harrassment[/ul]
However, FactCheck.org doesn't address whether or not Planned Parenthood was behind the bill or not, it's not even close to being mentioned,so the reporter must've been right, since he interviewed co-sponsors of the bill, and Mr. Martinez told York that Planned Parenthood made the recommendations, and had input into it.
