Did Michelle Obama Break Debate Rules by Clapping?

First Lady Michelle Obama appeared to break the debate rules last night by clapping:

Interestingly, Obama, wearing pink, is not applauding her husband, President Barack Obama--she is applauding debate moderator Candy Crowley.

As Real Clear Politics reports:

According to the rules both campaigns agreed to, or the memorandum of understanding (MOA), there is to be no clapping from members of the debate audience.

The rule: Article 9, Section A, Subsection 7: "All members of the debate audience will be instructed by the moderator before the debate goes on the air and by the moderator after the debate goes on the air not to applaud, speak, or otherwise participate in the debate by any means other than by silent observation, except as provided by the agreed upon rules of the October 16 town hall debate."
