From the September 13 edition of Fox News' Hannity:
SEAN HANNITY (HOST): Is there a chance she might have had a TIA, a stroke in her history? Is there a chance that there's something else neurologically going on? Is there -- for example, WikiLeaks has the research into some drugs that can be used for Parkinson's. Is that a possibility? M.S., a possibility?
KELLY POWERS: Yes, Sean, all of this is a possibility, and the point is that we don't have her medical records. We don't know, don't have a neurological work-up, so it's hard to speculate.
