I don't usually subscribe to conspiracy theories, but...

Politico reports that:

'The State Department said Saturday that Secretary of State Hillary Clinton fainted and suffered a concussion, but did not specify when that happened or the circumstances surrounding the incident.
She will not testify this week before House and Senate committees about the Sept. 11 attacks on Benghazi as scheduled, congressional sources said.'

Hmm, convenient?

If you like conspiracy theories then Politics & Finance have a doozy ...
