I don't think this can be presumed. The more I read about this the more uncertain about it either way. Here's a few questions: 1. Has a minor had an abortion at a PP clinic in the first place? 2. Does the AG has other evidence that a minor girl visiting PP for an abortion has had sex with an adult? 3. What are the consent laws in Indiana and Kentucky? 4. What are the confidentiality laws of those states? Without those this seems to be more of a fishing expedition on the part of the AG rather than the investigation of a specific crime. If the AG has other corroborating evidence and the consent and confidentiality laws allow it then IMO PP should be giving up names. Without that I don't see much here than a fixing expedition for political reasons.
Depends on the statute. Some of them specify that it is rape if the man is X years older than the minor. I am not sure of the specific laws in the states where this issue has been raised.
