A preposterous lie about how this attack was precipitated by a "spontaneous" demonstration in response to some obscure anti-Muslim video was concocted to follow a campaign narrative that al Queda was crushed by Obama's policies. In perpetrating this lie US security was jeopardized and the attackers are walking free to plot another attack. This lie was concocted at the highest levels of government and certainly Obama himself knew of the cover up. This should be ample grounds for impeachment.
The other unanswered question was why the ambassador was in Benghazi and not at the more secure US embassy in Tripoli.
Worst of all they attacked our rights to Freedom of Speech by alleging that a stupid YouTube video was the cause of it.
