Here was Ms. Rice's Statement after speaking to a Senate Panel about Benghazi, and her roll in lying to the American People (Emphasis mine):
In the course of the meeting, we explained that the talking points provided by the intelligence community, and the initial assessment upon which they were based, were incorrect in a key respect: there was no protest or demonstration in Benghazi. While we certainly wish that we had had perfect information just days after the terrorist attack, as is often the case, the intelligence assessment has evolved. We stressed that neither I nor anyone else in the Administration intended to mislead the American people at any stage in this process, and the Administration updated Congress and the American people as our assessments evolved.
Get that, "neither I nor anyone else in the Administration intended to mislead." But we already know the facts are that terrorist action, and not some YouTube Video, was already known to be the cause of the Benghazi attack. We know that the CIA submitted talking points that addressed the terrorist attack. So if they never "intended to mislead," did they instead believe that the CIA was lying to them?
No. They didn't believe that, but they're hoping you'll believe that they believe that.
So, to be clear one more time:
The Secretary of State had to sign off on leaving the Benghazi compound under-defended. Since Obama was routinely pointing to Libya as a foreign policy success, it is unreasonable to believe that he was unaware of that decision, and could have over-ruled his Secretary of State.
When the attack occurred, the White House had immediate visual intelligence via drone and the compound's own security cameras. They knew the nature of the attack. Nevertheless, someone made the decision not to send help. Remember, that was an active order: "stand down." Barack Obama could have over-ridden that order. He was either not available (and therefore derelict in his duty as President and Commander in Chief) or actively chose not to override that order, thus sentencing our people to death.
After the attack occurred, the White House approved a set of talking points to be delivered by Ambassador Susan Rice which explicitly excluded any reference to a terror attack, and instead referenced a "spontaneous demonstration" which they already knew had never existed.
Barack Obama consigned those men to death, and then lied to the American People about it.
He must be immediately impeached.
Update: Commenter 'Jane D'oh' at the AoSHQ points out that Susan Rice is also partially responsible for Bill Clinton's decision not to take Bin Laden when Sudan offered him to us on a silver platter.
