Dereliction of duty at the highest level. This is a case of malicious neglect, purely for political purposes. Clearly, both Hillary Clinton and Barack Obama knew that the situation in Libya was unraveling and that security for personnel stationed there should have been given the highest priority.
It wouldn't look good in the news though if it were discovered that Hillary Clinton's pet project of "killing Muammar Gaddafi" was turning into Somalia, the sequel. So they denied security, allowed the assassination of our ambassador and three others all for putting on a false political front. I believe the applicable word that applies here is "Impeachment."
