I followed the links and tried to find other sources but this blog, DC Whispers, is the only source I could find for this story. Also, the article says Clinton has nothing planned after October 23rd. In fact there is another event listed at the linked site for October 25 in Denver. It could be that events are still being added.
The Whispers site provides a link to American Thinker blog but it does not work.
Her campaign schedule runs through the 23rd, and she has no further events planned. This means that apart from the two events this Monday and the 90-minute debates on the 9th and 19th, Hillary will not show her face for twenty days.
