Hillary Used Her Uncomfortable Laugh To Duck Tough Questions:

PITTSBURGH, Pennsylvania (CNN) – Hillary Clinton used her trademark laugh Thursday to deflect a question about the $800,000 her husband earned in 2005 giving speeches for a Bogota-based group that supports the Colombia free trade agreement — the same trade deal she currently opposes.

Asked by CNN if those earnings represented a conflict of interest given that she has dipped into her family's pocketbook to pay campaign bills, Clinton threw up her hands and laughed loudly for several seconds.

"How many angels dance on the head of the pin?," she responded, continuing to giggle. "I have really, uh, nothing to … I mean, how do you answer that?"

She's done this before. Chelsea can't answer the Monica question and Hillary can't answer, well Hillary can't seem to answer anything.
