The White House, Obama Administration and campaign lied about the events the led up to the killing of four Americans, including our ambassador to Libya, in Benghazi. This was all about politics. After all, Obama has been taking victory laps over the killing of bin Laden and has basically claimed al Qaeda is defeated. The killing of bin Laden put a dent in al Qaeda, but had not defeated it or its many off shoots.
Of course, this administration has issues with calling all of this whay it is, a war on terror. They initially claimed that the Fort Hood massacre was "workplace violence", even though the terrorist was screaming Allah akbar! So now they have to try and convince us it was some movie trailer that caused all of this. They have to or it proves that Obama's outreach and apology to the Islamists was and is a total failure, like most of his foreign policy!
One must ask the question, what did Obama know and when did he know it?
