you can do a see also within a footnote to accommodate a note in a note and you certainly can have expository footnotes that explain the text more i just read through the article again and i think it may have gone too far in the whitewash direction for example it's ok to say that she clarified her educational background and have a footnote but the footnote ought to say what was being clarified this way is too vague and not at all clear that there was some obfuscating going on similarly saying her role in a potential giuliani administration and not saying even in footnote what was controversial i think is misleading there may be a few other places too i'm all for npov and not suggesting that this be an attack article but i think as i said it's gone too far over toward a whitewash talk
