RU-486, in smaller than standard dosages, can be used as an emergency contraceptive. That's not it's most common purpose, and I would agree the author of the article misspoke.
Anyone have a link to the report to the Clinton Administration that's discussed? I'd like to reat that whole puppy.

That's the closest I can find for now. It involves going through a lot of documents though. They start at page 18, before then, it's a summary basically.
It's not the same drug. Mifepristone, RU-486, is used on established pregnancies, not as a morning-after pill (which is a concentrated dosage of normal birth control pills). You seem to share the author's misconception (terrible pun, I know).
